Cover pictureThe cover shot for the 2016 Australian Weather Calendar Rain over sand dunes near Mungo NSW

The photographer was travelling through Mungo National Park in late February 2014 knowing the 40degC temperatures and instability from a low-pressure lsquotroughrsquo through the region could make for some dramatic weather

ldquoI noticed the convection develop 50 km to the northwest of my location Determined to catch it I made my way through 30 km of 4WD tracks and scaled multiple sand dunes to this ridge line to arrive just in time as the storm hit and proceeded to dump rain thunder and lightning and outflow winds of an estimated 70 kmhrdquo

Editorial

Tick-tock Time itrsquos just one of the many things we canrsquot control in life and something we may all be feeling the pressure of this time of year (How long have those Christmas ldquoshopsrdquo been on display for now I think at least two months)

Thinking back I recall my first test at university was to draw and label the geological timescale in as much detail as possible The time we were given to ldquolearnrdquo the timescale (I had never seen it before) was just one night It was worth something like 5 of our final mark for first year geology Though that was just the start of a miserable journey for me time itself still fascinates me

Much has happened in Australia in the time since the last issue of BAMOS Australia now has a new Prime Minister (who got down to business pretty quickly and has already awarded his first round of Prime Ministerrsquos Science Prizes) Alan Finkel was announced as the next Chief Scientist NASA found evidence of flowing water on Mars and of course one of the bestmdashin my opinionmdashmovie trilogies about time was (or should have been) celebrated with ldquoBack to the Future Dayrdquo

Time is also a key feature of our AMOS 2016 conference theme ldquoFrom Minutes to Millenniardquo This theme reflects the challenges that scientists experience when working on different and sliding timescales but also draws from the past to address future challenges

There are now less than three months left until AMOS 2016mdashthough AMOS 2015 was only four months ago Having two consecutive conferences so close together has meant that much of the efforts of the Society has been on

conferences for the past year or somdashand this will continue to be so until AMOS 2016 draws to a close

However for this issue of BAMOS I am particularly grateful to everyone who contributed such great articles and picturesmdashit means that the focus in this issue drifts away from the AMOS conferences and instead takes a closer look at what some of our active AMOS Centres have been up to

(But just in case you forgot about AMOS 2016 Irsquove posted a reminder for you below)

Tom Beer also takes us across to Paris where he recently attended the preparatory science conference before the upcoming COP21 meeting

Neville Nicholls examines media interest in climate change and Kaitlin Alexander takes us through the Paleocene-Eocene Thermal Maximum ocean acidification mystery

As always I also learned a great deal from our regular columnists Blair Trewin and Damien Irving

It was exciting for me to receive and read these stories for BAMOS and I hope that you all enjoy reading them too See you next time

Positioning AMOS policies A question that Irsquom sometimes asked and have difficulty answering is ldquoWhat is the AMOS policy position view on ______ rdquo I can certainly answer this question about my views and about what I think AMOS policy should be However my opinions are not AMOS policy and may not properly represent the views of the AMOS membership Unfortunately AMOS currently has few actual formal policies or positions This is a challenge for us as a society and limits our ability to meet our strategic goals to be advocates for our profession and be a source of independent information

AMOS policies must reflect the broad views of the membership along with being consistent with the highest quality peer-reviewed scientific evidence available Our positions should be in line with our expertise formed with the desire to inform and educate the general public and provide policy relevant information to governments

AMOS policy must underpin AMOS submissions to government inquiries and other public statements (eg to the media)

In the recent past most AMOS statements or submissions have been created by members of the AMOS Executive with input and subsequent approval by the AMOS Council Often this process occurs on very short timelines This approach is certainly within the AMOS rules but in my opinion has sometimes proven to be an ineffective way to form policy Except for AMOS membersrsquo role in electing Council the AMOS membership is not included in much of the current policy process Yet the most robust forms of AMOS policy should also include feedback from the membership and thus truly representing the views of the Society

If this became our strict measure of what defines AMOS policies then we only have a few in place the AMOS rules and the AMOS strategic and operational plans These have all been created through consultation with the entire AMOS membership but are not outward-looking policies We also had the AMOS position statement on climate change our only position statement which was adopted almost 10 years ago through a member-wide consultation process (Council has since retired this statement when it became out-dated)

In discussions with the American Meteorological Society (AMS) leadership wersquove learned that they have addressed

this issue by devising a highly structured way of creating policymdashfor a large part through their policy and position statement process The AMS currently has more than 30 statements in force and each is created through a rigorous procedure involving experts AMS Council and the AMS membership These policies form the basis of essentially all of their public commentary which is drawn from relevant parts of the appropriate statements

I advocate a similar approach for AMOS where we devise a range of policies and positions to facilitate better engagement with the public and advocacy on behalf of our field Our size makes it unrealistic to create 30 or more statements but we certainly need more than we currently have

As a starting point we are in the process of updating the AMOS position statement on climate change Many thanks to Blair Trewin and Ailie Gallant for leading this effort as well as AMOS Council for their feedback to date The draft statement has recently been circulated for member comment Once comments are received and adequately addressed (to the satisfaction of the AMOS Council) this statement will become AMOS policy

Although critically important AMOS positions should not be limited to climate change There are many topics in our fields that deserve formal statements As you may recall we are currently creating a small number of AMOS expert groupsmdashthese groups will help AMOS broaden our policy portfolio through leading the writing of other AMOS position statements

The consultative processes used to create AMOS policy will likely lead to some issues being portrayed more conservatively than some people might like Yet these concerns should be outweighed by the value of having positions that broadly represent the views of the entire Society The statements will be valuable not only for our purposes but to inform and educate the general public and governments Indeed the previous version of the AMOS position statement on climate change was highly valuable in that regard

February image for the 2016 Australian Weather Calendar Dust devil near Mount Bryan Image Jacob Elliot

Co-produced by the Bureau and AMOS the not-forshyprofit Australian Weather Calendar is the countryrsquos most popular calendar

Each year the publication attracts hundreds of entries from across the Australian community Entries exceeded 800 for the 2016 versionmdashthe 32nd year of its publication

Each image in the calendar is accompanied by an explanation of the underlying meteorology

The image above is Februaryrsquos feature This was captured by Jacob Elliot in South Australia He was chasing a storm near Mt Bryan in South Australia on 7 January 2015 hoping to take some photos of the lightning When he looked back towards Burra and saw a towering dust devil his objective changed

Dust devils or willy-willies are formed when a localised pocket of hot air rises quickly through cooler air above it The rapidly rising air pocket is replaced by air rushing in below it This inflowing air often arrives in an uneven manner and can start to rotate As the air pocket continues to rise and stretch the speed of rotation increases in the

same way as a twirling ballet dancer drawing in their arms and legs spins faster In dry areas dust is drawn into the rotating air columnmdashgiving dust devils their name and distinct appearance Jacob was using a Canon 600D with an EF-S 18ndash55 mm lens

A depiction of the new icebreaker Image DamenDMS MaritimeKnud E Hansen AS courtesy of the Australian Antarctic Division

Last month the Australian Government revealed plans for Australiarsquos new icebreakermdasha modern sophisticated ship offering scientists unprecedented and extended access to the Southern Ocean and Antarctica

The once-in-a-generation investment by the Australian Government forms the centrepiece of Australiarsquos Antarctic presence and will influence the shape of Australiarsquos Antarctic programme for decades to come

The icebreaker will be faster larger stronger and offer increased endurance compared with the ageing AuroraAustralis which has been battling the stormy Southern Ocean since 1989

The new ship provides a modern platform for marine science research in both sea ice and open water and a moon pool for launching and retrieving remotely operated vehicles A multi-beam bathymetric echo sounder will enable seafloor mapping while portable and flexible science laboratories will offer scientists space to conduct cutting edge research

The new icebreaker is expected to be commissioned in October 2019

Spectacular new era in satellite meteorology unveiled Bureau of Meteorology

Sun rising over Australia as seen from the Himawari-8 Image Bureau of Meteorology bomgov auaustraliasatellite

The Bureau now has near real-time imagery from the Japanese Himawari-8 satellite available to the public via its new web viewer Himawari-8 is currently the most advanced dedicated weather satellite in the world

Bureau Director and CEO Dr Rob Vertessy said the benefits are enormous

ldquoHimawari-8 is one giant leap in satellite meteorology itrsquos like switching from black and white TV to high definition colour in one jump Or you could compare it to switching from the grainy images of the silent era to IMAX You can see unfolding weather in detail wersquove only dreamed of in the past But itrsquos more than just eye-candy for our forecastersrdquo Dr Vertessy said

ldquoHimawari-8 generates about 50 times more data than the previous satellite Our forecasters now have access to 16 observation wavebands that capture important detail from many layers of the atmosphererdquo he said

ldquoPreviously we received a satellite image just once every hour now we get a detailed scan of our part of the globe every 10 minutes It brings the conditions on earth to liferdquo

ldquoCombined with the coming upgrade to our supercomputer Himawari-8 is a game changer Weather computer models ingest data and extrapolate to provide

a forecast The better the data we put in the better the forecast that comes outrdquo

ldquoOur forecasters are now starting to make use of the vast quantity of new data One of the most immediate benefits is the ability to see storms as they develop We expect to see continual growth in our use of the data over the coming yearsrdquo

Jamie Briggs Minister for Cities and the Built Environment attended the launch on behalf of the Australian community Japanrsquos Ambassador to Australia Mr Sumio Kusaka attended as Japanrsquos representative

Dr Vertessy expressed gratitude to the Japan Meteorological Agency for making the data from Himawari-8 freely available to Australia

ldquoThere is a wonderful tradition of global cooperation in meteorology The Japan Meteorological Agency is making a big investment in Himawari-8 close to a billion Australian dollars and the Australian community can share the benefits We are extremely grateful for the excellent relationship we have with our counterparts in Japanrdquo he said

Six months of El Nintildeomdashevent still going strong Bureau of Meteorology It is now six months since the 2015 El Nintildeo became established in the Pacific During this time oceanic and atmospheric indicators have been persistently strong comparable to the events of 1997ndash98 and 1982ndash83 International climate models suggest the peak in El Nintildeo sea surface temperatures is likely to occur before the end of the year then gradually ease in the first quarter of 2016

Sea surface temperatures in the central tropical Pacific as of 10 November are around 24 degC above average the largest anomaly for this event so far Other indicators of El Nintildeo such as the Southern Oscillation Index (SOI) cloudiness near the Date Line and trade winds still reflect strong El Nintildeo conditions despite some weakening in the SOI in early November

The positive Indian Ocean Dipole (IOD) event is also persisting This event has been in place for over three months International climate models expect the positive IOD to break down during November and early December More broadly Indian Ocean temperatures remain very warm the October sea surface temperatures anomaly for the Southern Hemisphere Indian Ocean was the highest positive anomaly for any month on record

El Nintildeo is usually associated with below-average spring rainfall over eastern Australia and increased spring daytime temperatures south of the tropics A positive IOD typically reinforces the drying pattern particularly in the southeast During summer El Nintildeorsquos influence on rainfall decreases while warmer daytime and night-time temperatures continue to be more likely across the south and east

Australia better prepared for drought with new programme Bureau of Meteorology As a strengthening El Nintildeo brings drier warmer weather to Australiamdashpotentially expanding drought affected areasmdashBureau of Meteorology Director and CEO Dr Rob Vertessy says the country is better able to anticipate the impacts on water resources thanks to the Australian Governmentrsquos Improving Water Information Programme

Speaking during National Water Week last month Dr Vertessy explained the national programme was initiated at the peak of the Millennium Drought following frustration amongst water policy makers due to inadequate information on the state of Australiarsquos water resources

Dr Vertessy said ldquoThe Millennium Drought made us acutely aware of how tenuous our water security was Well into that drought we had a very piecemeal view of how much water was held in storage present in aquifers running in rivers and being used in rural areasrdquo

ldquoFurthermore we had no ability to forecast the volume of water flowing into our reservoirs in the weeks and months ahead making it even harder to manage our severely diminished water supplies at the timerdquo

That situation was the catalyst for the creation of the Improving Water Information Programme founded on the ethos that ldquoyou cannot properly manage what you do not measurerdquo

Since the start of that programme eight years ago the Bureau of Meteorologymdashthe lead national organisation for collecting and disseminating water information under the Federal Water Act 2007mdashhas released an extensive portfolio of new water information products and services

The Bureau has been working closely with State water agencies urban and rural water utilities and research organisations to enhance the availability and value of water information and to provide a nationally consistent view with weather and climate data provided by the Bureau

One of the key services coming out of this work is the National Water Account which documents annual changes in water stores and flows water rights and water use in Australiarsquos most significant water supply systems The recent inclusion of Queenslandrsquos Burdekin region means the account now captures up to 85 of Australiarsquos water use

Various online products accessible on the Bureaursquos website provide continuous updates on the amount of water held in water storages on the volume of river flows on groundwater levels on water restrictions and on water market activity

The Bureau now provides valuable insight into what lies ahead too forecasting river flows for the next seven days at over 100 sites and seasonal streamflow outlooks for over 140 sites across the nation

ldquoWersquove come a long way since the Millennium Drought with much improved situational awareness and foresight regarding our nationrsquos most valuable natural resource waterrdquo Dr Vertessy said

ldquoThe next time Australia approaches a serious water security crisis we wonrsquot be flying blind Our vastly improved water information will mean that governments businesses and communities are far better prepared and able to action mitigation strategies much sooner and at a lower costrdquo he said

Brisbane Centre news Michael Hewson Secretary Brisbane Regional Centre

On Thursday 5 November some 20 or so members and guests of the Brisbane Regional Centre of the Australian Meteorological and Oceanographic Society met for a bite of lunch This included a briefing about the summer weather outlook from Dr Richard Wardle Richard is the Supervising Meteorologist at the Bureau of Meteorology Queensland Regional Office

After catching up on atmospheric climate and oceanographic interests of participants over lunch we learnt about the Queensland summer to comemdashoutlooks for tropical cyclones storms and bushfires in the context of lingering El Nintildeo climatological conditions Richard took some time to comment on what has been learnt about flood history post-El Nintildeo periods as well

The meeting discussed briefly the merits of tying an entire outlook on a single climate index noting the competing needs of public communication and the complexities being explored by atmospheric science

Thanks to Tamika Tihema and Katie Rosemond Bureau staff and AMOS members for arranging the session It was a good rollup of members

The Brisbane Regional Centre has some plans for some further meetings including an early February talk from Professor Roger Smith on Northern Australian meteorological phenomena

Later in 2016 we hope to possibly arrange a workshop where participants can work up an accreditation on climate risk assessmentmdashthat will be a very practical experience

Gliding and meteorologymdashAMOS takes to the air Matt Woodhouse CSIRO

Andrea Dittus and Matt Woodhouse prepare to launch Image Sonya Fiddes

The AMOS Melbourne Centre recently organised two visits to Benalla airfield to fly with the Gliding Club of Victoria (GCV) On 15 August and 5 September despite unappealing weather in Melbourne members were greeted with fine blue skies on arrival in Benalla

GCV Vice President Tim Shirley welcomed AMOS members and then proceeded to give an overview of soaring meteorology describing how glider pilots use thermals to stay in the air By searching for and circling in thermals glider pilots gain heightmdashwhich they can use to look for and fly to the next thermal and so travel very large distances During the long summer days pilots from Benalla regularly achieve distances in excess of 1000 km with average speeds of over 100 kmh Conditions at Benalla are so good in fact that the Australian National Championships will be hosted there in January 2016 followed by the World Championships the following year Timrsquos presentation was very well received and prompted many astute questions

With the conclusion of Timrsquos presentation our intrepid AMOS aviators moved out to the launch point where sunglasses were donned sunscreen applied and picnic blankets spread The sleek white two-seat gliders were waiting and after being introduced to the glider and instructor each member was strapped in and prepared for take-off The launches were by aerotow a light powered aircraft towing the glider to 3000 ft above ground The GCV instructors flew the gliders from the rear seat giving unobstructed views from the snow-capped Australian Alps to the south and across the Murray River into NSW After releasing the rope at 3000 ft members were given the chance to take control of the glider Several members were lucky enough to find thermals to extend their flights no mean feat in mid-winter And a couple of adrenaline-seekers were even treated to some aerobatics and high-speed flying before landing back at the airfield

Many thanks to the Gliding Club of Victoria for making the day happen and laying on perfect weather The question is when can we go again

Effects of the EAC on Tasmania Andrew Klekociuk and Andrew Marshall Hobart Regional Centre

AMOSmdashAMSA Public Lecture Summary On the evening of 18 August the Hobart Centres of the Australian Meteorological and Oceanographic Society (AMOS) and the Australian Marine Sciences Association (AMSA) hosted a public event at the University of Tasmaniarsquos Stanley Burbury Theatre examining the physical behavior and ecosystem implications of changes in the East Australian Current (EAC) Titled Feeling theEffects of the East Australian Current on Tasmania the event featured 15 minute talks by speakers Associate Professor Neil Holbrook (University of Tasmania and ARC Centre of Excellence for Climate System Science) Associate Professor Gretta Pecl (University of Tasmania) and Dr Mike Pook (CSIRO) followed by a 40-minute panel question-and-answer session with the audience Dr Scott Ling (University of Tasmania) facilitated as Master of Ceremonies and provided input for the panel discussion The event was repeated the following night (19 August) at the University of Tasmaniarsquos Sir Raymond Ferrall Centre in Launceston

Prof Holbrook set the scene by describing the oceanographic features of the EAC Pioneering work by CSIRO from the 1960s described the general transport regimes associated with the EAC which involves a broad flow southward along the continental shelf to approximately 30˚S which transitions into eddies

further south and a branch that heads eastward towards New Zealand In the mid-1980s work by the Scripps Institution of Oceanography produced large-scale maps of ocean circulation and contextualised the EAC as part of the broader South Pacific Gyre (SPG) circulation During the 1990s analysis of long-term records showed that the south-west Tasman Sea is warming to significant depth An intensification of the East Australian Current extension (largely composed of anti-cyclonic eddies) consistent with forcing from changes in the large-scale wind stress field across the mid-high latitude South Pacific Ocean has been implicated as a key driver of the warming Recent modelling suggests that further changes in the SPG will result in increased southward extension of long-lived warm-core (anti-cyclonic) eddies along the Tasmanian east coast and this will be accompanied by an increase in sea surface temperature extremes south and west of the Tasman Sea warming

Prof Pecl provided a description of observed oceanic ecosystem changes that are linked to warming of the EAC in the Tasmanian region Documented changes include southward expansion of sea urchins that have caused loss of kelp forests the southward migration of a significant portion of intertidal species and seaweeds and major distributional changes in over 45 coastal fish species Many of these changes have been directly witnessed by Scott Ling who has undertaken more than 1700 dives to research



changes in urchin populations off eastern Tasmania Prof Pecl highlighted that while general southward movements in species have been seen the overall picture is complicated as movements of some species are hard to detect and not all species are capable of moving and adapting to environmental change In order to obtain a clearer picture of change in the marine environment Prof Pecl has been central in the development of the Range Extension Database and Mapping (lsquoRedmaprsquo httpwww redmaporgau) project which is hosted by the University of Tasmania and involves the identification and location of ldquoout of rangerdquo species through public participation Recent results from the project have shown that some widely distributed species are shifting faster in response to change along the Australian east coast and that change is greatest in the lower trophic levels Overall the data gathered by Redmap are proving valuable for wider efforts in modelling and for informing decisions about conservation and management

Dr Pook went on to describe the implications of changes in the EAC to climate and weather patterns in the Tasmanian region While the Tasmanian west coast has the highest annual rainfall accumulation as a result of its orographic placement in the general westerly flow regions of the north-east experience the highest daily rainfall amounts Extreme rainfall events in the Tasmanian northshyeast are invariably associated with cut-off lows when low pressure systems become stationary between blocking highs to the east and west of the state Modelling such as that conducted for the Climate Futures for Tasmania project indicates that future warming of the EAC may

lead to more intense cut-off lows to the east of Tasmania and provide higher rainfall intensity during these events Overall the understanding of these extreme events is informing planning in the agricultural fisheries and business sectors

Following the talks there was strong engagement with the audience which consisted of 185 people in Hobart and 50 people in Launceston including researchers teachers academics and those outside academia with broad interest in weather climate and oceanography

Generous support for the event was provided by the University of Tasmania National Science Week and the Australian Institute of Physics Partner organisations also included Inspiring Australia the Institute for Marine and Antarctic Studies CSIRO and the ARC Centre of Excellence for Climate System Science

Climate change driving species redistribution Craig Macaulay Hobart Regional Centre

International researchers will present the latest assessment of how climate change is driving a redistribution of Earthrsquos species when they meet in Hobart next February

The conference Species on the Move is being held for the first time to evaluate shifts occurring throughout the worlds lands and oceans but particularly in recognised global hotspots such as Australiarsquos south-east and south west waters

The co-coordinator Associate Professor Gretta Pecl is from the University of Tasmaniarsquos Institute for Marine and Antarctic Studies She said between 25ndash85 of marine and terrestrial species in any given area have been recorded as having moved to new environments with climate change considered to be the primary factor in the redistribution

The conference follows four themes detection impacts prediction and adaptation

ldquoWhile the mechanisms that underpin redistribution are poorly understood the overwhelming nature of range shiftsmdashfrom poles to the equator and ocean depths to mountains topsmdashoffers a rare opportunity to advance scientific theory of biogeography evolutionary ecology and global changerdquo Prof Pecl said

ldquoEssentially this is an evolving field of science tracking animals birds fish and mammals to identify how and where species will move with climate change the impact of a change in our environment and in the face of such changes how to sustainably manage natural resources such as commercial fish populationsrdquo she said

Up to 250 scientists are expected to attend the conference at Hobartrsquos Grand Chancellor from February 6ndash9 and hosted by the University of Tasmania

Conference Report

lsquoOur Common Future under Climate Changersquo Conference (CFCC) report Paris 6-11 July 2015 Tom Beer

Background

This conference was organised by an international partnership of Future Earth ICSU and UNESCO (along with numerous French organisations) to be the preparatory science conference before the COP21 meeting in Paris in December 2015 But you may ask surely the Intergovernmental Panel on Climate Change (IPCC) meetings are the preparatory science meetings Indeed but whereas IPCC works under a ldquoscience for policyrdquo regime CFCC appeared to have a more overtly political agenda designed to influence COP21 into producing agreements (unlike Copenhagen)

The conference had strong support from the French Governmentmdashthe French President was scheduled to open the conference but pulled out at the last minute because of the currency crisis in Greecemdashand French institutions So much so that I was told that the University of Pierre and Marie Curie (UPMC) insisted on hosting sessions This meant that half of the conference was at the eastern end of Paris and the other half was at the western end of Paris Twenty minutes by metro between the two locations

The four days of the conference were organised as

bull Day 1 State of Knowledge on Climate Change

bull Day 2 Landscapes of Our Common Future

bull Day 3 Responding to Climate Change Challenges

bull Day 4 Collective Action amp Transformative Solutions

I attended this conference in Paris because it almost directly followed on from the end of the IUGG General Assembly in Prague (a weekend intervened) and I felt that in my role as a member of the ICSU Committee of Scientific Planning and Review I should attend this ICSU organised conference and in my role as Chair of the IUGG Commission on Climatic and Environmental Change I should attend to foster further interactions with key players in Future Earth

My role was to display a poster about the Weather Climate and Food Security program run by the IUGG Commission on Climatic and Environmental Change

The conference published a day-by-day electronic newsletter of activities I have reproduced the salient bits in the Appendix

Personal Highlights

A new look at Resilience

Following the Plenary speeches on Day 2 there was a plenary panel discussion titled Contours of a Resilient Global Future with J Rockstroumlm (Stockholm Resilience Centre Stockholm Sweden) L Fernaacutendez Carril (Universidad Nacional Autoacutenoma de Meacutexico Ciudad de Meacutexico Mexico) A Gavilano (Environmental Policy Analysis Bern Switzerland)

This was memorable because Dr Carril took issue with the use of the word resilience as being a good thing He claimed that we do not want to be resilient we want to make sure that we have been adequately prepared that we do not need to be resilient Resilience is defeatism

Rockstroumlm the head of a resilience institute defended his position by claiming that he agreed with Carril that mitigation was neededmdashbut if events have gone too far for mitigation then adaptation is needed and that is what resilience is all about

Curiously enough on the plane home I read a book ldquoTheBeginning of Infinityrdquo by David Deutsch FRS Professor of Physics at Oxford University who makes a similar point in Chapter 17 in relation to ldquosustainabilityrdquo Deutsch argues against a sustainable world as being one that is static and lacks innovation He argues for unsustainability as being needed to keep us innovative and able to provide new solutions

Boycotts for Climate

Damian Carrington Head of Environment at The Guardiannewspaper described the paperrsquos keepitintheground campaign to divest financial support from fossil fuel companies He called it a campaign ldquorooted in the reality that therersquos far more carbon locked in the ground than we can safely burnrdquo This was followed by a panel discussion with New York Times journalist Andrew Revkin and Dagmar Dehmer of German newspaper Der Tagesspiegelon the rights and wrongs of journalism as advocacy Revkin said that US journalists seek to present both sides of an argument and Dehmer said that such a divestment campaign violates every ethical code of German journalism A lively QampA session with the audience followed that discussed the roles and responsibilities of both journalists and scientists when communicating about climate change

What I took away from this and interpolated into a discussion at the World Congress on Risk in Singapore two weeks later was that the approach to climate change communication differs according to the nationality of the communicator

AppendixmdashOfficial Summary of Each Dayrsquos Events

Day 1

Our Common Future Under Climate Change kicked off to a packed auditorium for the opening plenary French Research and Education Minister Najat Vallaud-Belkacem issued a stark warning saying that ldquounless we have widespread climate action we will be the generation that knew what had to be done but didnrsquot do itrdquo Segolegravene Royal French Minister for the Environment Energy and Sustainable Development echoed the same message calling on scientists to speak with a clear voice in the run-up to the Paris climate change negotiations in December

ldquoWe have won the battle of ideas now we must win the battle for actionrdquo she said She also reminded scientists that while science has a duty to provide proof and evidence ldquoto be heard in the preparations for the summit in Paris as you deserve your voices must not be too tangled up in precautionsrdquo

There are transcripts available of WMO Secretary-General Michel Jarraudrsquos speech and the speech he delivered on behalf of UN Secretary-General Ban Ki-Moon

Many of the presentations can be found on the conference Slideshare page httpwwwslidesharenetCFCC15

Day 2

In the first plenary Karen OrsquoBrien of the University of Oslo recognized the need for adaptation while acknowledging that there are some risks under higher warming that we cannot manage She also pointed out that addressing climate change is not only a technical problem but forces us to ask what risks we can accept or tolerate which is a question of beliefs and values Paul Leadley of the Universiteacute de Paris-Sud argued that our common future should recognize the value of the many species with whom we shared the planet whose options under climate change are limited to ldquomove adapt or dierdquo

Day 3

The conference turned towards a focus on responding to the challenges of climate change Many speakers highlighted the urgency of reducing emissions to lessen the risks of climate change and in many cases pointed out win-win solutions to do so In daringly PowerPoint-free reflections Saleemul Huq noted that adaptation is not just dealing with risks but taking opportunities to be better offand make transformational change He also cautioned that itrsquos very doubtful that adaptation can be a solution in a +3 or +4degCworld sharpening the need for mitigation

Several speakers highlighted the need to articulate an attractive vision of a low-carbon future Ken Caldeira encouraged attendees to imagine the world we would like to create with healthy happy prosperous people In a parallel session moderator Jeffrey Hardy echoed this need


Conference Report

saying ldquoI want to see the aspirational sense of wanting to live in a low-carbon future If you love technology itrsquos smart and data-heavy if you love your community itrsquos a better place to live Therersquos clean air for everyone Donrsquot we want to live there anyway even if climate change didnrsquot existrdquo

In the plenary Fatih Birol noted that not only visions but specific targets will be critical to send the signal for emitters like the energy sector to meet ambitious goals including an emissions peak in 2020 In Thursdayrsquos press briefing Diana Uumlrge-Vorsatz shared an example of ambitious goals spurring change much faster than expected ldquoWhen we wrote about zero-energy buildings less than a decade ago most researchers didnrsquot think it was possible Today itrsquos in European law The law came out before the scientific community was convinced it was feasible The regulations pushed the industry to innovate and itrsquos having a very significant impact Really a miracle happenedrdquo

Day 4

In Fridayrsquos morning plenary Hans Joachim Schellnhuber of the Potsdam Institute for Climate Impact Research sounded a clarion call that ldquothe age of carbon is overrdquo He warned that ldquoit is a very bad idea to go beyond two degreesrdquo and suggested ldquoLetrsquos take this as the reference line what are we going to do about itrdquo He said that if there is any chance of avoiding dangerous climate change

an ldquoinduced implosion of the carbon economyrdquo is needed adding that the responsibility for financing the transition cannot lie with the poor ldquoit is not the poor who will pay for this transition that is ludicrousrdquo He said that if we are willing to invest in a long-term future for our children in the form of their education we should also invest in the climate those children will live in

In the closing plenary Scientific Committee Chair Chris Field summed up the conference

ldquoWe are moving to a post-carbon era where climate change mitigation and adaptation are combined with other goals to build a sustainable futurerdquo noting the deep commitment of scientists to be part of the solution He also presented the conference Outcome Statement which emphasized that for a two in three probability holding warming to 2degC or less we have a remaining carbon budget of about 20 yearsrsquo worth of current emissions To achieve a stable climate emissions eventually must go to zero Conference attendees are invited to make use of the statement in their communications

Field also emphasized that science has an essential role in highlighting connections between objective observations of the Earthrsquos state and the human questions raised by climate change ldquohow we think about the interests of the poor versus the rich the future versus the present and nature versus economiesrdquo

Article

Increased media interest in climate change Neville Nicholls Monash University

Climate scientists are sometimes disheartened by the low level of knowledge of and interest in climate change displayed by politicians and some sections of the media But there is evidence that the message about climate change is getting out One part of this evidence is the increasing frequency of media articles about climate change and global warming

The website Chronicle (chroniclenytlabscom) allows us to chart how the frequency of articles published in the New York Times that mention specific words or terms has changed over the years Figure 1 shows the annual frequency of articles published in the New York Times that mention ldquoglobal warmingrdquo and ldquoclimate changerdquo The figure shows that the frequency of articles mentioning either ldquoclimate changerdquo or ldquoglobal warmingrdquo has risen over time since the early 1970s Since about 2008 ldquoclimate changerdquo has become the more frequently used of the two

terms as the frequency of articles using ldquoglobal warmingrdquo has declined

Yet some articles might only have used the term ldquoclimate changerdquo while some may have only used ldquoglobal warmingrdquo and others may have used both terms There is no simple way to determine the frequency of articles mentioning ldquoclimate changerdquo andor ldquoglobal warmingrdquomdashthis frequency would be a clearer indication of New York Times interest in the topic of climate change But we can use the frequencies shown in Figure 1 to estimate upper and lower bounds for the frequency of such articles The upper limit each year (the maximum frequency) is the sum of the frequency of articles using either ldquoclimate changerdquo or ldquoglobal warmingrdquo (it is of course possible that an article could be written about climate change without using either of the terms ldquoglobal warmingrdquo or ldquoclimate changerdquo but this seems unlikely) For this ldquomaximumrdquo estimate to be correct would


Article

Figure 1 Frequency of New York Times articles using ldquoclimate changerdquoor ldquoglobal warmingrdquo 2015 figure calculated using data up to 7 September 2015 Data from chronicle nytlabscom

Figure 2 Maximum and minimum estimates of frequency of New York Times articles using either ldquoclimate changerdquo or ldquoglobal warmingrdquo or both terms Other details as in Figure 1

imply that no article using the term ldquoglobal warmingrdquo also used ldquoclimate changerdquo and vice versa The lower limit (the minimum frequency) is the larger of the two frequencies in Figure 1 in each year (this would imply that all articles that mentioned ldquoclimate changerdquo also mention ldquoglobal warmingrdquo and vice versa) Figure 2 displays how these maximum and minimum estimates of the frequency of articles on climate change have varied over the years The frequency of articles each year mentioning either ldquoclimate changerdquo or ldquoglobal warmingrdquo (or using both terms in one article) must lie between these maximum and minimum estimates

New York Times interest in climate change peaked in 2007ndash2009 then declined somewhat before rebounding over the last two years possibly reaching its maximum in 2015 Figures 1 and 2 indicate that over the past decade about 15 of all New York Times articles have mentioned climate change or global warming This may seem quite a low frequency until it is compared with the frequency of articles mentioning ldquoterrorismrdquo (173 of all articles in 2015) ldquoSyriardquo (227) ldquorefugeerdquo (069) ldquoEbolardquo (049)

ldquoflurdquo (029) or ldquomalariardquo (018) So in the context of other topics of considerable public media and political interest the interest in climate change in the New York Times has been substantial The evidence is that climate scientists have been successful in raising media interest in climate change and that this interest is continuing to grow

The direct influence of climate scientists in fostering media interest is evident in the two figures The early assessment reports of the Intergovernmental panel on Climate Change (IPCC) in 1990 and 1995 were associated with quite small increases in media interest But subsequent IPCC assessments (2001 2007 201314) have seen substantial jumps in the number of media articles on climate change The major meetings of the United Nations Framework Convention on Climate Change (UNFCC) in 1997 (Kyoto) and 2009 (Copenhagen) have also been associated with increased media interest as has the lead up this year to the Paris UNFCCC meeting in December So it seems that the pain and time spent preparing IPCC assessments or in UNFCCC meetings have been worthwhile after all

Solving the PETM ocean acidification mystery Kaitlin Alexander Climate Change Research Centre (CCRC) ARC Centre of Excellence for Climate System Science University of New South Wales

The Paleocene-Eocene Thermal Maximum 55 million years ago left behind puzzling evidence of deep ocean acidification New climate model research at UNSW may finally shed light on this event as lead author Kaitlin Alexander explains

In order to find an example of previous climate change comparable to what wersquore experiencing today you have to go back 55 million years The Paleocene-Eocene Thermal Maximum (PETM) was an episode of global warming and ocean acidification caused by increasing greenhouse gases In May of this year my co-authors Katrin Meissner Tim Bralower and I published a paper in Nature Geoscience which sheds new light on a long-standing mystery about ocean acidification during the PETM

The PETM occurred after the extinction of dinosaurs but before the emergence of humans Ocean sediments laid down during this event show that the average global temperature increased by around 5degC over a few thousand years (Zeebe et al 2009) We can expect a similar amount of warming over the next few hundred years if we continue burning fossil fuels at our current rate

Itrsquos also clear from the sediment record that this warming was driven by a large release of carbon into the atmosphere Nobody is sure where this carbon came from but possible explanations include peat burning or methane released from the seafloor

Itrsquos difficult to figure out exactly how much atmospheric CO2 increased during the PETM because there were no ice sheets present to record its concentration Instead we can measure the severity of ocean acidification based on calcium carbonate content in ocean sediments and calculate how much extra CO2 would be needed to explain that ocean acidification

The problem is that ocean acidification was not uniform during the PETM It was more severe in the Atlantic than it was in the Southern Ocean and the Pacific and until now nobody has known why The different regions give two different answers as to how much CO2 increased and until now we havenrsquot known which answer to trust

Using simulations with the University of Victoria Earth System Climate Model my co-authors and I have identified a mechanism which may explain this discrepancy In our simulations ocean acidification during the PETM was more severe in the Atlantic because CO2 was not the only contributing factor It was exacerbated by changes in ocean circulation due to warming which caused a parcel of corrosive water to spread through the Atlantic dissolving sediments in its path

At 55 million years ago global bathymetry was quite different from today In particular there was a ridge on

the seafloor between the North and South Atlantic near the equator This ridge completely isolated the deep North Atlantic from other oceans like a giant bathtub on the ocean floor In our simulations this ldquobathtubrdquo is filled with corrosive water which has low alkalinity and so can easily dissolve calcium carbonate This corrosive water originated in the Arctic Ocean and was able to sink to the bottom of the Atlantic by mixing with dense salty water from the Tethys Ocean (the precursor to todayrsquos Mediterranean Black and Caspian Seas)

In our simulations this corrosive bottom water gradually warmed in response to the PETM As it warmed it became less dense until the vertical density gradient was sufficient for deep water formation the denser surface water sank and pushed the corrosive bottom water up and over the ridge This corrosive water spread southward through the Atlantic eastward through the Southern Ocean and into the Pacific dissolving sediments as it went (Figure 3a of the original paper) It became diluted as it travelled and so the most severe effects were felt in the South Atlantic This pattern agrees with sediment records which show close to 100 dissolution of calcium carbonate in the South Atlantic

The PETM is often considered an analogue to modern climate change since the carbon release which caused the PETM was probably similar in magnitude to that of present-day fossil fuel reservoirs (Meissner et al 2014 Swart and Weaver 2012) although it was released about ten times more slowly However the unusual conditions we simulate in the North Atlantic during the PETMmdashan isolated deep basin filled with very corrosive water in a region susceptible to deep water formationmdashhave no analogue in the modern ocean Therefore we have no reason to believe that similar releases of corrosive water

Managing your data

If yoursquore working on a project that involves collecting or generating novel data that would be of interest to the wider research community (eg you might be participating in a scientific ocean voyage or a model intercomparison project) then itrsquos likely that one of the first things you did was develop a data management plan Many funding agencies actually formally require this and such plans usually involve outlining your practices for collecting generating organising backing up and storing your data

What many people donrsquot realise is that even if you arenrsquot collecting or generating your own data (eg you might simply be downloading a reanalysis dataset) you should still start your project by developing a data management plan That plan obviously doesnrsquot need to consider everything a full-blown data collectiongeneration project does (eg you donrsquot need to think about archiving the data at a site like Figshare) but there are a few key things all data analysis projects need to consider regardless of whether they produced the original dataset or not

1 Data Reference Syntax The first thing to define is your Data Reference Syntax (DRS)mdasha convention for naming your files As an example letrsquos look at a file from the data archive managed by Australiarsquos Integrated Marine Observing System (IMOS)

threddsdodsCIMOSeMIIdemosACORNmonthly_gridded_1h-avg-current-map_non-QCTURQ2012IMOS_ACORN_V_20121001T000000Z_TURQ_FV00_monthly-1-hour-avg_END-20121029T180000Z_C-

20121030T160000Znc

Thatrsquos a lot of information to take in so letrsquos focus on the structure of the file directory first threddsdodsCltprojectgtltorganisationgtltcollectiongtltfacilitygtltdata-typegtltsite-

codegtltyeargt

From this we can deduce even without inspecting the contents of the file that we have data from the IMOS project that is run by the eMarine Information Infrastructure (eMII) It was collected in 2012 at the Turquoise Coast Western Australia (TURQ) site of the Australian Coastal Ocean Radar Network (ACORN) which is a network of high frequency radars that measure the ocean surface current The data type has a sub-DRS of its own which tells us that the data represents the 1-hourly average surface current for a single month (October 2012) and that it is archived on a regularly spaced grid and has not been quality controlled The file is located in the ldquodemosrdquo directory as it has been generated for the purpose of providing an example for users at the very helpful Australian Ocean Data Network user code library1 1 httpsgithubcomaodnimos-user-code-library



Just in case that file ever gets separated from this informative directory structure much of the information is repeated in the file name itself along with some more detailed information about the start and end time of the data and the last time the file was modified ltprojectgt_ltfacilitygt_V_lttime-startgt_ltsite-

codegt_FV00_ltdata-typegt_lttime-endgt_ltmodifiedgtnc

In the first instance this level of detail seems like a bit of overkill but consider the scope of the IMOS data archive It is the final resting place for data collected by the entire national array of oceanographic observing equipment in Australia which monitors the open oceans and coastal marine environment covering physical chemical and biological variables Since the data are so well labelled locating all monthly timescale ACORN data from the Turquoise Coast and Rottnest Shelf sites (which represents hundreds of files) would be as simple as typing the following at the command line

$ ls ACORNmonthly_TURQROTnc

While itrsquos unlikely that your research will ever involve cataloging data from such a large observational network itrsquos still a very good idea to develop your own personal DRS for the data you do have This often involves investing some time at the beginning of a project to think carefully about the design of your directory and file name structures as these can be very hard to change later on The combination of bash shell wildcards and a well-planned DRS is one of the easiest ways to make your research more efficient and reliable

2 Data provenance When defining my own DRS I usually add some extra fields to cater for the intermediary files that typically get created throughout the data analysis process For instance I add a field to indicate the temporal aspects of the data (eg to indicate if the data are an anomaly relative to some base period) and another for the spatial aspects (eg to indicate whether the data have been re-gridded) While keeping track of this information via the DRS is a nice thing to do (it definitely helps with bash wildcards and visual identification of files) more detailed information needs to be recorded for the data to be truly reproducible A good approach to recording such information is the procedure followed by the widely used Climate Data Operators (CDO) and NetCDF Operators (NCO) Whenever an NCO or CDO utility is executed at the command line a time stamp followed by a copy of the command line entry is automatically appended to the global attributes of the output netCDF file thus maintaining a complete history of the data processing steps Herersquos an example global attribute entry from a CDO command I ran just the other day

ERAInterim_500hPa_1993-030day-runmean_nativenc

You might be thinking ldquothis is all well and good but what about data processing steps that donrsquot use NCO CDO or even netCDF filesrdquo It turns out that if you write a script (eg in Python R or whatever language yoursquore using) that can be executed from the command line then it only takes an extra few lines of code to parse the associated command line entry and append that information to the global attributes of a netCDF file (or a corresponding metadata text file if dealing with file formats that donrsquot carry their metadata with them) To learn how to do this using Python check out the Software Carpentry lesson on Data Management in the Ocean Weather and Climate Sciences2

3 Backup Once yoursquove defined your DRS and implemented the NCOCDO approach to data provenance the final thing to think about is backing up your data This is something I discussed in detail in the August 2014 issue of BAMOS but the crux of the story is that if your starting point files (ie the data files required at the very first step of your data processing) can be easily downloaded (eg reanalysis or CMIP5 data) then you probably donrsquot need your local copy backed up All of your code should be version controlled and backed up via an external hosting service like GitHub or Bitbucket so you can simply re-download the data and re-run your analysis scripts if disaster strikes If you generated your starting point files from scratch on the other hand (eg you collected the data during a field experiment) then backup is absolutely critical and would be part of your data management plan

20 March 1978 The El Nintildeo event of 1977ndash78 brought dry conditions in late 1977 and early 1978 to much of eastern Australia The July to February period was the fifth-driest on record for Victoria and the ninth-driest for New South Wales and dryness continued into the first half of March 1978

A broad low-pressure system formed in the Coral Sea far to the north-east of Brisbane on the 17th with a secondary low east of Bundaberg These consolidated into a subtropical low east of the Gold Coast on the 18th The low moved close to the coast on the 19th before moving inland and south-west By the 20th it was centred near Dubbo with an increasingly strong easterly flow between it and a high pressure system over Tasmania The low gradually weakened over the next two days and moved first southshywest then south-east into a trough over the far south-east of New South Wales on the 22nd A new small low formed in the trough off the mid-north coast of New South Wales on the 24th before the system was finally swept away by a strong cold front on the 26th

Whilst the heaviest rains from east coast lows are normally quite localised this event brought heavy rain to almost all of coastal New South Wales Weekly totals exceeded 200 mm along almost the entire coast from the Gold Coast to the Victorian border with 100+mm totals extending inland to the ranges

Initially the heaviest falls were in the Gold CoastTweed region with Murwillumbah receiving 321 mm on the 19th and a two-day total for 18ndash19 March of 509 mm at Springbrook The strongest winds of the event also occurred during this period including a gust of 131 km h at Nobbys Head in Newcastle

Over the next two days though the focus of the heaviest rain moved to the area immediately west and south of

Sydney The heaviest falls of all were near the Illawarra escarpment with a three-day total of 884 mm (including 348 on the 20th) for 19ndash21 March at the St Anthonyrsquos site near Robertson while Bowral had three successive three-figure daily totals on its way to a three-day fall of 415 mm The Blue Mountains also experienced very heavy rain with an all-time daily record of 285 mm at Katoomba On the 21st the heaviest rain moved to the coastal escarpment of the South Coast Cottesloe southeast of Nimmitabel had 366 millimetres (the second-highest daily fall on record for the Southern Tablelands) and Badja 263 mm

Canberra (where 92 mm was a March record at the time) was about the western limit of the heavy rain most of inland New South Wales and Victoria got rain but two-day totals for 20ndash21 March west of the ranges were mostly in the 10ndash20 mm range with only locally higher falls

Despite relatively dry catchments leading into the event such heavy rains produced significant flooding in many coastal catchments especially the Manning Paterson HawkesburyNepean Shoalhaven Richmond Tweed and Hastings Six deaths occurred during the event mostly in western Sydney and many properties were inundated around Windsor Maitland Taree and Wingham (where the Manning River reached its second-highest level on record) With very strong inflows from both the Wingecarribee and Coxs Rivers Warragamba Dam spilled producing the highest flood since 1964 at Windsor (and one not matched since) The situation around Taree was exacerbated when 236 millimetres fell on the 25th fromthe secondary low but these rains were fairly localised and had little impact outside that area AMENDMENT The photograph accompanying Charts From the Past in the last issue was captioned incorrectly The photograph was taken in August 1929 not SeptembermdashEd

7 We recommend that the author(s) make five suggestions for referees to undertake the peer-review Also we ask for a list of five potential referees whom the author does not want as reviewers due to conflicts of interest or past close association

8 Once peer-review has been completed a final version of the document should be sent to the editor either in Word format or as plain text The document should also include figure and table captions and the references but no figures Figure files should be sent separately (they may be in any format and the editor will confer with the author(s) on the resolution and formatting)

9 Galley-proofs will be sent to the author(s) for final checking before publication

BAMOS also accepts a wide range of non-peer-reviewed work for example news items charts from the past conference reports book reviews biographical articles and meet a member AMOS members are therefore encouraged to submit articles that would be of general interest to the AMOS community without necessarily requiring peer review File formats should follow those given above a word or plain text document should be submitted (which includes any figure captions and tables) along with any figure files given separately

All articles should be either posted or emailed to the editor with any questions on the formatting also directed to the editor (see the inside back cover of this issue for contact details)

Cover pictureThe cover shot for the 2016 Australian Weather Calendar Rain over sand dunes near Mungo NSW

The photographer was travelling through Mungo National Park in late February 2014 knowing the 40degC temperatures and instability from a low-pressure lsquotroughrsquo through the region could make for some dramatic weather

ldquoI noticed the convection develop 50 km to the northwest of my location Determined to catch it I made my way through 30 km of 4WD tracks and scaled multiple sand dunes to this ridge line to arrive just in time as the storm hit and proceeded to dump rain thunder and lightning and outflow winds of an estimated 70 kmhrdquo
