PAST COLD ARCTIC PRESENT WARMER ARCTIC

Higher pressure sub-tropic constrained the low-pressure arctic

Lower pressure difference allows waves of arctic air to invade the South: Warmer & Colder Winters.

Weather Extremes: Cold Air Oscillates South from the ArcticThe Arctic is warming faster than the rest of our earth.

Therefore the temperature and the accompanying pressure difference that used to keep arctic air up North comes South, bringing cold air to Atlanta & New Orleans.

Using a conservative prediction of a half meter (20 inches) of sea-level rise, the Organization for Economic Co-operation and Development estimates that by 2070, 150 million people in the world’s large port cities will be at risk from coastal flooding, along with $35 trillion worth of property—an amount that will equal 9 percent of the global GDP.

Sea Level Rise ‘Locking In’ Quickly, Cities Threatenedhttp://www.climatecentral.org/news/sea-level-rise-locking-in-quickly-cities-threatened-16296

Published: July 29th, 2013

Carbon pollution to date has already locked in more than four feet of sea-level rise past today’s levels.

That’s enough, at high tide, to submerge more than half of today’s population in 316 coastal cities and towns, home to 3.6 million people, in the lower 48 states.

Other cities projected to be 50 percent underwater: Galveston, Texas, by 2030; Norfolk, Virginia; and Coral Gables, Florida, by 2044.

“That’s one place I’m really nervous about,” says Richard Alley, a glaciologist at Penn State University and an author of the last IPCC report. “It involves the physics of ice fracture that we really don’t understand.” If the Thwaites Glacier breaks free from its rocky berth, that would liberate enough ice to raise sea level by three meters—nearly ten feet. “The odds are in our favor that it won’t put three meters in the ocean in the next century,” says Alley. “But we can’t absolutely guarantee that. There’s at least some chance that something very nasty will happen.”

Hurricane Sandy •At least 100 U.S. deaths. •Economic losses expected to climb as high as $50 billion. •Eight million homes without power.

The broadening scientific consensus:

*Climate change amps up other basic factors that contribute to big storms.

*The oceans have warmed, providing more energy for storms.

*The Earth’s atmosphere has warmed, so it retains more moisture, which is drawn into storms and is then dumped on us.http://www.businessweek.com/articles/2012-11-01/its-global-warming-stupid

NY City is highly vulnerable to storm surges.

Storm surges are responsible for much of the damage and loss of life associated with land falling hurricanes.

The combined effects of storm climatology change and a 1 m Sea Level Rise may cause the present NYC 100-yr surge flooding to occur every 3–20 yr.

The Next Hurricane, and the NextBy THE NY Times EDITORIAL BOARD

•The rebuilding strategy report, from the President’s Hurricane Sandy Rebuilding Task Force, identifies 11 climate-related disasters costing an estimated $110 billion in damages in the last year alone.

•Congress made important changes last year to the financially distressed National Flood Insurance Program, reducing subsidies that have made this insurance affordable.

•Now homeowners can either pay much higher insurance rates if they leave things the way they are or they can reconfigure their houses to prepare for the next disaster. Reconfiguring could mean raising the house on pylons above the high-water level.

•Taxpayers should not be paying to rebuild and then re-rebuild as the sea level rises.

Frequency of occurrence (vertical axis) of local June-July-August temperature anomalies (relative to 1951-1980 mean) for Northern Hemisphere land in units of local standard deviation (horizontal axis). Temperature anomalies in the period 1951-1980 match closely the normal distribution ("bell curve", shown in green), which is used to define cold (blue), typical (white) and hot (red) seasons, each with probability 33.3%. The distribution of anomalies has shifted to the right as a consequence of the global warming of the past three decades such that cool summers now cover only half of one side of a six-sided die, white covers one side, red covers four sides, and an extremely hot (red-brown) anomaly covers half of one side. Source: Hansen, J., Sato, M., and Ruedy, R., Proc. Natl. Acad. Sci., 2012.

Loaded Climate Dice: global warming is increasing extreme weather events.Extreme summer heat anomalies now cover about 10% of land area, up from 0.2%. This is based on observations, not models.

Wildfires in Western US have increased 4-fold in 30 years.

The effects of global warming on temperature, precipitation levels, soil drying, and Western Pine beetles are turning many of our forests into kindling for more wildfires.(Westerling, A.L, et al.

An Inconvenient Ice:Methane Hydrates Could Power the Planet—or Fry ItMethane hydrates could solve the world's energy challenge—or make global warming worse.Sep 16, 2014 |By Lisa Margonelli

http://www.scientificamerican.com/article/methane-hydrates-could-power-the-planet-or-fry-it/

Page 40: Global Warming: Why Be Concerned?

Methane hydrate, "Fire ice natural gas hydrate” is a solid clathrate compound in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.

Found where temperatures are low and water ice is common, significant deposits of methane clathrate have been found under sediments in the ocean.

It is also trapped within the Arctic tundra.

Methane discovery stokes new global warming fears & shock, as retreat of Arctic releases greenhouse gas

 13 Dec 2011 http://www.independent.co.uk/news/science/methane-discovery-stokes-new-global-warming-fears-shock-as-retreat-of-arctic-releases-greenhouse-gas-6276278.html

Methane is a greenhouse gas 50 times more potent than carbon dioxide.

“Earlier we found torch-like structures like this but they were only tens of metres in diameter. This is the first time that we've found continuous, powerful and impressive seeping structures more than 1,000 metres in diameter.” Dr Semiletov American Geophysical Union meeting in San Francisco. 

The total amount of methane stored beneath the Arctic is calculated to be greater than the overall quantity of carbon locked up in global coal reserves.

The Coming Climate Crash:Lessons for Climate Change in the 2008 RecessionBy HENRY M. PAULSON Jr. Secretary of the Treasury under Pres. George W. Bush.JUNE 21, 2014 http://www.nytimes.com/2014/06/22/opinion/sunday/lessons-for-climate-change-in-the-2008-recession.html http://riskybusiness.org

“We’re staring down a climate bubble that poses enormous risks to both our environment  and economy. The warning signs are clear and growing more urgent as the risks go unchecked.

A tax on carbon emissions will unleash a wave of innovation to develop technologies, lower the costs of clean energy and create jobs as we and other nations develop new energy products and infrastructure.

Climate change is the challenge of our time. We’ve seen and felt the costs of underestimating the financial bubble. Let’s not ignore the climate bubble.”

Page 44: Global Warming: Why Be Concerned?

What Can We Do?

Page 45: Global Warming: Why Be Concerned?

Long Term Solution to Reduce C02 Emissions

The American Clean Energy and Security Act of 2009, Markey-Waxman bill passed the House of Representatives by a narrow margin.

A cap and trade system, under which the government sets a limit (cap) on the amount of greenhouse gases, mostly C02, that can be emitted. Utilities like coal that exceed the limit must buy permits from non-carbon emitters, nuclear, hydro, solar, wind. This increases the cost of coal generation, but reduces that of non-carbon emitters.

Short Term Response We can not afford it because it would increase the cost of energy. ”It would ruin our economy.” The Senate did not pass the bill.

We already having to pay:Since 1996 over $1 billion damage doubled compared with the previous 15-year period.

Page 46: Global Warming: Why Be Concerned?

Fixing Climate Change May Add No Costs, Report SaysNY Times, Sept 16, 2014

The Global Commission on the Economy & the Climate.

•An ambitious series of measures to limit emissions would cost $4 trillion or so over the next 15 years, an increase of roughly 5 percent over the amount that would likely be spent anyway on new power plants, transit systems and other infrastructure.

•When the secondary benefits of greener policies — like lower fuel costs, fewer premature deaths from air pollution and reduced medical bills — are taken into account, the changes might wind up saving money.
