UN Climate Body (IPCC) Too Slow, Too Cautious

Stephen CLIMATE CHANGE/GLOBAL WARMING, Energy, ENVIRONMENT, Media, News, Science , ,

The review of the IPCC (Intergovernmental Panel on Climate Change) has been completed and concluded that the science is sound. Of course that is not what many in the blogosphere are saying.

As a journalist my experience with the IPCC over past decade has been that their communication is terrible. The Summary for Policy Makers report is unreadable except by the most dedicated jurno with good salary and few deadlines…

Secondly public statements by IPCC are so qualified with caveats to require telepathy to parse the real meanings.

Finally compared to my reading of the latest science the IPCC is woefully out of date and conservative to a fault.

In my view much of the current criticism of the IPCC is misdirected and done so to deliberately confuse the public about the reality of the near and present danger of climate change.

I have interviewed scientists and other experts about how the findings and integrity of climate science/scientists have been systematically attacked and distorted by those with vested interests:

Summary of the InterAcademy Council Review from the excellent Australian science blog Climate Shifts:

The long-awaited review of the IPCC has been delivered by the InterAcademy Council (an Amsterdam-based organization of the world’s science academies). Contrary to the misguided expectations of the denialist community, the Inter-Academy Council has concluded that the periodic assessment reports of the IPCC have been successful overall. There is some need, however, for improving some of the reporting process and for developing a better set of processes to deal with the growing scientific and political complexity of the climate change issue.

Here is the press release posted today by the InterAcademy Council (IAC).

Last year’s cold and snowy winter directly connected to warmer Arctic new research reveals

By Stephen Leahy

OSLO, 15 June 2010 (IPS)

Last winter’s big snowfall and cold temperatures in the eastern United States and Europe were likely caused by the loss of Arctic sea ice, researchers concluded at the International Polar Year Oslo Science Conference in Norway in June.

Climate change has warmed the entire Arctic region, melting 2.5 million square kilometres of sea ice, and that, paradoxically, is producing colder and snowier winters for Europe, Asia and parts of North America.

“The exceptional cold and snowy winter of 2009-2010 in Europe, eastern Asia and eastern North America is connected to unique physical processes in the Arctic,” said James Overland of the NOAA/Pacific Marine Environmental Laboratory in the United States.

“In future, cold and snowy winters will be the rule rather than the exception” in these regions, Overland told IPS.

[[UPDATE Dec 29 2010 – Winter of 2010-11 appears to follow same pattern, see new post with northern hemisphere temp map for 20 Dec:  Arctic Hothouse Turns Europe into an Icebox]]

Scientists have been surprised by the rapid warming of the Arctic, where annual temperatures have increased two to three times faster than the global average. In one part of the Arctic, over the Barents and Karas Seas north of Scandinavia, average annual temperatures are now 10 degrees C higher than they were in 1990.

Overland explains the warming of the Arctic as the result of a combination of climate change, natural variability, loss of sea ice reflectivity, ocean heat storage and changing wind patterns, which has disrupted the stability of the Arctic climate system. In just 30 years, all that extra heat has shrunk the Arctic’s thick blanket of ice by 2.5 million square kilometres – an area equivalent to more than one quarter the size of the continental U.S.

The changes in the Arctic are now irreversible, he said. Continue reading →

Heat Waves Put Global Food Supply At Risk

[New Article]

By Stephen Leahy

VIENNA, Aug 11, 2010 (IPS)

A wind turbine on an acre of northern Iowa farmland could generate 300,000 dollars worth of greenhouse-gas-free electricity a year. Instead, the U.S. government pays out billions of dollars to subsidise grain for ethanol fuel that has little if any impact on global warming, according to Lester Brown.

“The smartest thing the U.S. could do is phase out ethanol subsidies,” says Brown, the founder of the Washington-based Earth Policy Institute, in reference to rising food prices resulting from the unprecedented heat wave in western Russia that has decimated crops and killed at least 15,000 people.

“The lesson here is that we must take climate change far more seriously, make major cuts in emissions and fast before climate change is out of control,” Brown, one of the world’s leading experts on agriculture and food, told IPS.

Average temperatures during the month of July were eight degrees Celsius above normal in Moscow, he said, noting that “such a huge increase in temperature over an entire month is just unheard of.”

VIENNA, Jul 31, 2010 IPS

The oceans are the lifeblood of our planet and plankton its red blood cells. Those vital “red blood cells” have declined more than 40 percent since 1950 and the rate of decline is increasing due to climate change, scientists reported this week.

“Phytoplankton are a critical part of our planetary life support system. They produce half of the oxygen we breathe, draw down surface CO2, and ultimately support all of our fisheries,” said

Boris Worm of Canadas Dalhousie University and one of the worlds leading experts on the global oceans.

“An ocean with less phytoplankton will function differently,” said Worm, the co-author of a new study on plankton published this week in Nature. Plankton are the equivalent of grass, trees and other plants that make land green, says study co-author Marlon Lewis, an oceanographer at Dalhousie.

“It is frightening to realise we have lost nearly half of the oceans’ green plants,” Lewis told IPS.

“It looks like the rate of decline is increasing,” he said.

Independent environmental journalism now depends on public support, learn more about how this works and how you can help, click here.

Climate change is warming the oceans about 0.2C per decade on average. This warmer water tends to stay on top because it is lighter and essentially sits on top of a layer of colder water. This layering, or stratification, is a problem for light-loving plankton because they can only live in the top 100 to 200 meters.

Eventually they run out of nutrients to feed on unless the cold, deeper waters mix with those near the surface. Ocean stratification has been widely observed in the past decade and is occurring in more and larger areas of the world’s oceans. Continue reading →

Stephen Leahy interviews science historian NAOMI ORESKES

PARIS, Mar 24, 2010 (IPS)

Even though 2009 was the fifth warmest year since 1850, and 2000-09 the warmest decade ever, according to the World Meterological Organisation, surveys show that public concern about global warming in the United States and Canada has dropped sharply in the past 18 months.

Why? Because of a relentless disinformation effort from an unlikely cabal of fossil fuel interests, Christian evangelicals and the media, says Naomi Oreskes, a professor of history and science studies at the University of California, San Diego.

“They have managed to reopen the debate over global warming in people’s minds,” she told IPS.

Oreskes and co-author Erik Conway, a science historian at the Jet Propulsion Laboratory, document similar efforts to manufacture doubt around the science on acid rain, the ozone hole, secondhand cigarette smoke, and the pesticide DDT in their just published book, “Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming”. [Tons of excellent reviews —  the “eye-opener of the year” says one reviewer.]

In 2004, Oreskes was vilified on TV, radio and in print by commentators for providing clear evidence there was in fact a scientific consensus on global climate change. Her essay in the journal Science examined all of the peer-reviewed scientific papers on climate over the previous 10 years and found none dissented with the theories that climate change was occurring and it was caused by humans. Her survey has never been successfully challenged, despite many attempts.

IPS environmental correspondent Stephen Leahy spoke to Oreskes over the phone. Excerpts of the interview follow.

Q: Where is the vehement opposition to the very idea that we need to do something about climate change?

A: Some of it is ideological, part of a long history in the United States that equates environmental regulation as going down the slippery slope to socialism. And some is religious. Christian evangelicals don’t like science in general and have found common cause with the coal industry as a way to be able to teach creationism. Obviously, the motivation of the coal industry is rather different but now these people have come together to undermine science in general.

“This government is doing nothing on climate but they always make sure to sound like they’re doing something to fool Canadians.” — John Bennett, Sierra Club of Canada

By Stephen Leahy

UXBRIDGE, Canada, Mar 16, 2010 (IPS)

Canada’s climate researchers are being muzzled, their funding slashed, research stations closed, findings ignored and advice on the critical issue of the century unsought by Prime Minister Stephen Harper’s government, according to a 40-page report by a coalition of 60 non-governmental organisations.

“This government says they take climate change seriously but they do nothing and try to hide the truth about climate change,” said Graham Saul, representing Climate Action Network Canada (CAN), which produced the report “Troubling Evidence”.

“We want Canadians to understand what’s going on with this government,” Saul told IPS.

Climate change is not an abstract concept. It already results in the deaths of 300,000 people a year, virtually all in the world’s poorest countries. Some 325 million people are being seriously affected, with economic losses averaging 125 billion dollars a year, according to “The Anatomy of a Silent Crisis“, the first detailed look at climate change and the human impacts.

Released last fall by the Geneva-based Global Humanitarian Forum, the report notes that these deaths and losses are not just from the rise in severe weather events but mainly from the gradual environmental degradation due to climate change.

“People everywhere deserve to have leaders who find the courage to achieve a solution to this crisis,” writes Kofi Annan, former U.N. secretary-general and president of the Forum, in the report.

Canadians are unlikely to know any of this. Continue reading →

OUR Roof is on Fire: Dangerous Climate Change is Here

It will take lot of us – probably in the streets” to make politicians face the truth, says climate scientist James Hansen.

[Dangerous climate change is already upon us say some of the best scientists we have. But political leaders — and most of the public — don’t get it. This is an attempt to close the chasm between climate reality and climate denial fantasy. I wrote this at the end of the Copenhagen Climate meetings last December thanks in part to financial contributions from readers that allowed me to do the research and interviews. — Stephen]

“Our leaders do not get the scale of the problem or the rapidity of the changes.”            — Andrew Weaver, climatologist at Canada’s University of British Columbia

Analysis by Stephen Leahy

COPENHAGEN Dec 22 ,2009 (IPS/TerraViva)

The roof of our house is on fire but our leaders, our economic system and we ourselves are ignoring the alarms and continuing to add more fuel. There are no exit doors in our house; there is nowhere else to go.

Dangerous climate change is already here.

The two-week climate summit in Copenhagen came to an end with disappointing results and details that are still vague.

A ”Copenhagen Accord” was agreed by the US, China, South Africa and India by Friday night. It was unclear which other countries were willing to support it.

But coral reefs are dying, the Arctic is melting and rising sea levels threaten the homes of millions. And we’re on our way to a planet-transforming four-degree C rise in global average temperatures in as soon as 50 years.

Future generations could face an utterly transformed planet, where large areas will be seven to 14 degrees C warmer, making them uninhabitable. In this world-on-fire, the one to two metre sea level rise by 2100 will leave hundreds of millions homeless, according to the latest science presented at the “4 Degrees and Beyond, International Climate Science Conference” at the University of Oxford in September.

That’s the science-based, slap-in-the-face reality as the Copenhagen climate talks fizzle out here with little progress Friday.

“Our leaders do not get the scale of the problem or the rapidity of the changes. They don’t get that it must be dealt with now,” said Andrew Weaver, a climatologist at Canada’s University of British Columbia and lead author of the Intergovernmental Panel on Climate Change (IPCC) reports.
