Why conserve land?
• To preserve sensitive natural areas
• To save forests, the lungs of the planet
• To preserve habitat for our fellow creatures
• To preserve the watersheds
• To preserve areas of natural beauty

Climate change…is it real?
Recent events, and scientific studies are forcing us to connect the dots between: our actions, and • the droughts, • fires, • floods, • tornadoes, • wars, • refugees, and • species extinction we see going on in our world.

The Science of 350
• Scientists say that 350 parts per million CO2 in the atmosphere is the safe limit for humanity.
![Page 15: Nature Conservation – Why is it necessary?giddy.org/jenny/conservation-why-1.pdf · push Japanese carbon emissions 2.4 percent higher in 2011. Coal or Natural Gas? – NIMBY! Who](https://reader033.vdocuments.net/reader033/viewer/2022051806/600269873534d1435445c902/html5/thumbnails/15.jpg)
Why 350?
• According to Bill McKibben, well-known environmentalist, author, and founder of 350.org, there are three numbers we need to understand global warming: 275, 392, and 350.
• Since the beginning of human civilization up until about 200 years ago, our atmosphere contained about 275 parts per million of carbon dioxide.
![Page 16: Nature Conservation – Why is it necessary?giddy.org/jenny/conservation-why-1.pdf · push Japanese carbon emissions 2.4 percent higher in 2011. Coal or Natural Gas? – NIMBY! Who](https://reader033.vdocuments.net/reader033/viewer/2022051806/600269873534d1435445c902/html5/thumbnails/16.jpg)
Beginning in the 18th century, humans began to
burn coal and gas and oil to produce energy
• The amount of carbon in the atmosphere began to rise, at first slowly and now more quickly.
![Page 17: Nature Conservation – Why is it necessary?giddy.org/jenny/conservation-why-1.pdf · push Japanese carbon emissions 2.4 percent higher in 2011. Coal or Natural Gas? – NIMBY! Who](https://reader033.vdocuments.net/reader033/viewer/2022051806/600269873534d1435445c902/html5/thumbnails/17.jpg)
Oops – we are now at 392ppm
• By now— the planet has about 392 parts per million CO2 – and this number is rising by about 2 parts per million every year.

Disastrous impacts are already being seen – Bill McKibben writes:
• Drought
• food scarcity
• More disease - mosquitoes spreading malaria and dengue fever
• Glaciers melting • Drinking water
disappearing

El Niño years – conflict doubles
• Solomon Hsiang and colleagues at Columbia University used data from the past half-century to show that in tropical regions, the risk of a new civil conflict doubles during El Niño years (when temperatures are hotter than usual and there is less rainfall).
• If that finding is correct, then a warming world could mean the end of the relatively peaceful era in which we are now living.

El Niño is here
• “Supported by the model forecasts and the continued warmth across the Pacific Ocean, the official forecast calls for the development of most likely a weak El Niño during September 2012, persisting through December-February 2012-13 (see CPC/IRI consensus forecast).”

Environmental effects worsening human conflicts
• Rising sea levels – flooding
• Increased intensity of extreme weather
• These impacts are combining to exacerbate conflicts and security issues around the world

Is the earth really getting warmer?
Yes, and there is complete agreement among several different temperature records that in the last 30 years it has warmed dramatically.

Population Growth Matching CO2 Emissions
The image shows the relationship between population and CO2 emissions.
It can be reasoned that an increase in population results in an increase in CO2 emissions.

How big is the problem of carbon dioxide in the earth's atmosphere?
• 80% of the world's energy comes from fossil
fuels.
• The current burning of fossil fuels -- oil, coal and natural gas -- releases 7 billion tons of carbon per year in the form of carbon dioxide, plus lots of other greenhouse gases.
• It's at least 10 times too much

International Energy Agency Report of June 2012
Described by the New York Times editorial as “Required reading for regulators and the industry — and for anyone who cares about energy, the environment and climate change”.
• CO2 emissions rose by 3.2% last year
• China was the biggest contributor to the global rise made, its emissions increasing by 9.3 percent, driven mainly by higher coal use.

According to the IEA: Business as usual = Devastating consequences
• "the trend is perfectly in line with a temperature increase of 6 degrees Celsius (by 2050), which would have devastating consequences for the planet,"
• Scientists say ensuring global average temperatures this century do not rise more than 2 degrees Celsius above pre-industrial levels is needed to limit devastating climate effects like crop failure and melting glaciers.

What kept the CO2 numbers down recently?
In the USA, a switch to natural gas from coal in power plants, a slower economy and a mild winter helped cut emissions by 1.7percent.

Recommendations for lowering our CO2 emissions
The International Energy Agency made these recommendations for world governments to help meet emission targets:
• cut fossil fuel subsidies
• boost energy efficiency
• move away from coal

What happens if we give up on Nuclear Power? – caught between a rock and a hard place
The IEA report warned about the impact of phasing out nuclear power output after the Fukushima accident in Japan, which helped push Japanese carbon emissions 2.4 percent higher in 2011.

Coal or Natural Gas? – NIMBY! Who can blame us for not wanting “Fracking”
in our backyard? • We’ve seen the documentary “Gasland” • We’ve seen the faucets on fire • We don’t want our wells contaminated with the big
companies’ secret chemical concoctions

Switching to natural gas…
That won’t solve climate change.
• But a gas-fired power plant emits only half as much carbon dioxide as a coal-fired plant.

Regulating fracking
• Gov. Andrew M. Cuomo is preparing a proposal that would allow hydraulic fracturing for gas only in Marcellus Shale areas where deposits are at least 2,000 feet deep.
• The plan would require the approval of municipalities for the gas-drilling process to begin in their areas.

Climate Change Results – More Wildfires
Headline, June 12th: Southwest drought, climate warming and fuel: an explosive combination for record wildfires
During the last two summers, wildfires have run rampant in the Southwest, setting record after record for size and destructiveness
![Page 40: Nature Conservation – Why is it necessary?giddy.org/jenny/conservation-why-1.pdf · push Japanese carbon emissions 2.4 percent higher in 2011. Coal or Natural Gas? – NIMBY! Who](https://reader033.vdocuments.net/reader033/viewer/2022051806/600269873534d1435445c902/html5/thumbnails/40.jpg)
Largest fires in states’ history
• Texas: Suffered its worst wildfire season on record in 2011 • New Mexico: Has had its two largest fires in state history the last two years. • Arizona: The Wallow Fire in 2011 consumed more than 500,000 acres, the
largest on record in that state. • Colorado: …the second largest wildfire in that state’s history. This fire has
burned more than 41,000 acres and “there’s no end in sight.” (June 2012)

What’s happening with the Climate in the
Western USA ...
The U.S. Drought Monitor shows much of Texas, New Mexico, Colorado, and Arizona under drought conditions ranging from moderate to exceptional. • In this region,
temperatures have warmed substantially since 1970.
• These states have been warming at a rate of about 0.5-0.6 degrees F per decade.

Why does climate change cause more
heavy rainfall events? Rising ocean temperatures allow tropical storms to keep more
of their strength as they travel northward over the ocean

Tropical Storms in the Hudson Valley
• The devastating floods of 2011 were caused by Tropical Storm Irene, which brought 6 inches of rain from August 27th to 28th.
• A week later, Tropical Storm Lee followed.
![Page 46: Nature Conservation – Why is it necessary?giddy.org/jenny/conservation-why-1.pdf · push Japanese carbon emissions 2.4 percent higher in 2011. Coal or Natural Gas? – NIMBY! Who](https://reader033.vdocuments.net/reader033/viewer/2022051806/600269873534d1435445c902/html5/thumbnails/46.jpg)
In 1999 Hurricane Floyd had less impact – why?
• At that time, we were five inches below normal for precipitation.
• Drier ground was able to absorb the rainfall, as were wetlands, lakes, and ponds.
• In comparison, before Tropical Storm Irene dumped her rain on us, we had already exceeded average rainfall by 8.25 inches.

• Also, warmer water expands.
• The USGS study suggests the Northeast would get hit harder because of ocean currents.

Accelerated sea level rise already happening in the Northeast – USGS report
• Since 1990, sea levels have gone up globally about 2 inches.
• But in Norfolk, Va., sea level has jumped a total of 4.8 inches
• For Philadelphia, levels went up 3.7 inches
• In New York City, it was 2.8 inches.
• The accelerated rate along the East Coast could add about 8 inches to 11 inches more.

Sea level rise in the Northeast prompts action now
• Over one million people live on land less than five feet above the high tide line in the Northeast corridor.
• New York’s subway system is quite vulnerable. If a storm pushes water a few inches above a threshold into the New York City subway system - the whole system could flood within 40 minutes.
• New York is responding to the threat by raising lips around the gratings above subways.

Farewell to the tiger
Here’s a choice: save the last remaining tigers on the planet, or kill them, chop them into pieces, and eat them in the mistaken belief that tiger parts can be used as medicine.

Chinese “Medicine” responsible for cruel killing, and decrease in numbers of tigers, rhinos, bears
• In terms of poaching, elephants had an awful year in 2011, and now we learn that the same thing can be said for rhinos.
• Reuters reports that rhino poaching in South Africa increased 33% in 2011, with 443 rhinos killed and half of that poaching occurring in Kruger National Park.
At current rates, the rhinoceros will be extinct in South Africa by 2015.

Why do we need the leatherback and all the rest of
the earth’s biodiversity?
• They are symbolic of the great biodiversity that inhabits the oceans.
• That biodiversity is threatened by human activities ranging from overfishing to global warming.
• “Leatherback turtles are the Pandas of the Pacific.”

• Third, even if we don’t need biodiversity, the species that make up that biodiversity have their own right to exist.
• All species have an inherent right to exist in the world.

Urban Sprawl
(1) About 1/3rd of the open space developed during our country’s entire history was lost in the last 3 decades;
(2) We continue to lose about 1.6 million acres of farms, forests, and other open lands each year
(3) The US Census Bureau estimates that by the end of the century the US population will have grown more than 30 percent from the present 309 million to about 400 million.
(The world population is anticipated to be 10billion by 2050)

Invasive Species
• By now, we are all aware of insects and plants in our own gardens that have become problem pests eg the oriental vine bittersweet strangling our shrubs, the beautiful purple loosestrife taking over the wetlands, kudzu “the plant that ate The South”, but who knew that Queen Anne’s Lace was not native to the northeast, but a European invader?!

About 60 percent of plants now considered invasive were introduced deliberately through the plant trade
• The other 40 percent are human-related accidental introductions such as seeds stuck in cargo or shipping containers. Only a tiny fraction of non-native introductions are from natural causes such as blowing in with a hurricane
Not all imported plants become invasive, but those that do can become a significant threat to native plants

Aliens at Wildcliff Nature Reserve
• Australian black wattle (acacia mearnsii) were imported to South Africa in the 1920’s for fence posts and firewood
• They will grow anywhere, they suck up all the moisture, and they secrete a toxin that prevents any other plant from growing beneath their canopy
• They are the biggest challenge facing Wildcliff, in terms of time, money and manpower.
• If left unchecked, they will create an ecological disaster for South Africa

The Oceans…
• Imagine an underwater world without whales, sharks, and dolphins, where jellyfish and algae rule. It's already happening, says marine biologist Callum Roberts in his new books, The Ocean of Life.
Causes:
• Chemical and industrial pollutants flowing into our rivers and oceans
• All that CO2 released by burning fossil fuel is gradually infiltrating the deep sea, changing ocean chemistry, impacting temperatures and oxygen levels,

The Rise of the Jellyfish
• The jellyfish joyride begins when high nutrients combine with a fall in abundance of their predators.
• Jellyfish suppress their predators further by eating more of their young and so pave the way for a full-blown population explosion.
Why are jellyfish populations booming? "Global warming, pollution, and human activity in marine habitats are not generally regarded as good things," says Gerry Bellet at the Vancouver Sun — "unless you're a jellyfish."

Fish less, Catch more
• A World Bank report aptly titled “The Sunken Billions: The Economic Justification for Fisheries Reform” calculated that major fish stocks of the world would produce 40 percent more if we fished them less.
• It sounds paradoxical—fish less to catch more—but that is the simple message.

“What can I do to help?”
• Avoid eating fish that are overexploited in the wild
• Try to avoid prawns or scallops and other bottom feeders fished up by dredgers and trawlers, such as plaice, cod, and hake.
• Eat low in the food web, so favor smaller fish like anchovies, herring, and sardines over big predators like Chilean sea bass, swordfish, and large tunas.

Study Shows Planet Keeping Pace
With CO2 Emissions • According to a new study, published in Nature, August 1st, 2012,
about half of the carbon dioxide we’ve pumped into the atmosphere by burning fossil fuels has been absorbed by plants and oceans
• Scientists are convinced this can’t go on forever — but at least we haven’t come to the danger point yet.
Whew!

Green roofs – such as this one on ConEd’s building in Manhattan
If New York City’s 1 billion square feet of roofs were transformed into green roofs, it would be possible to keep more than 10 billion gallons of water a year out of the city sewer system, absorb CO2 from the air. (It’s also cost effective – roofs last longer!)

White roofs • When I lived in Manhattan, and sometimes looked down
on all those black roofs, absorbing heat from the sun, I thought, why not cover them with white tarps in the summer, and revert to black in the winter.

Cow manure provides electricity
• The Huishan Dairy Farm in China uses an anerobic digestor to break down the organic matter in their cow’s waste.
• The farm is able to capture methane “from 60,000 of Huishan’s 250,000 cows to produce 5.66 megawatts of power.
• the plant could also generate 620,000 tons of fertilizer and reduce carbon emissions by 180,000 tons per year.

Health & Climate Change
• Maria Neira, director of public health and environment at the WHO:

The Conversion of a Climate-Change Skeptic
By RICHARD A. MULLER, Professor of Physics, UCLA, Berkeley
• CALL me a converted skeptic. Three years ago I
identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming.
• Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct.
• I’m now going a step further: Humans are almost entirely the cause.
• New York Times, July 28, 2012

Interview with Lester Brown
Q: What's the most important thing for humanity to start
doing?
Get the market to tell the ecological truth.
Calculate the cost of burning a gallon of gasoline, for example,
and incorporate the indirect cost in the form of a tax.
We're all economic decision-makers and we
respond to market signals. But the market's giving us bad information. I mean
grossly distorted information.

Q: What should I do? Talk to congressfolk? Write a letter to the editor? Buy a hybrid?
Lester Brown: Most of the people in audiences I'm talking with have been asking themselves that question. Recycle
paper, buy a Prius, whatever -- lifestyle changes.
But we've reached the point where we have to go beyond that. We now have to go for systemic change; otherwise we're not going to make it. That's why tax restructuring is so important. That means
becoming politically active.
Maybe it's lobbying city council or representatives in Washington, letting them know what we think, what we
want them to do. If enough of us do that, change will begin.

What can we do on a personal level?
• Keep informed – read widely, newspapers, magazines, Internet, books
• Online sources such as: 350.org and http://www.realclimate.org/ • Join local environmental organizations (think
globally, act locally) • Consider working with a conservancy to protect
your land in perpetuity • More to discuss in future lectures about what we
can do at home
