Federal Report: Warming = More Harmful Climate Extremes

Monday, June 23rd, 2008

The first thorough federal review of research on how global warming may affect extreme climate events in North America forecasts more drenching rains, parching droughts (especially in the Southwest), intense heat waves and stronger hurricanes if long-lived greenhouse gases continue building in the atmosphere.

The report is distinct from last month’s federal review of specific impacts of warming on agriculture, ecosystems, coasts and the like in the United States, focusing instead on how weather patterns will change. It also largely echoes, at the regional level, findings on global impacts from the Intergovernmental Panel on Climate Change last year.

The organisation of denial: Conservative think tanks and environmental scepticism

Saturday, June 21st, 2008

This worrisome research article has appeared in a peer reviewed journal. It’s not telling us anything that we didn’t already know, but it does catalogue the situation and help us steer clear of the hyperbole.

Environmental scepticism denies the seriousness of environmental problems, and self-professed ’sceptics’ claim to be unbiased analysts combating ‘junk science’. This study quantitatively analyses 141 English-language environmentally sceptical books published between 1972 and 2005. We find that over 92 per cent of these books, most published in the US since 1992, are linked to conservative think tanks (CTTs). Further, we analyse CTTs involved with environmental issues and find that 90 per cent of them espouse environmental scepticism. We conclude that scepticism is a tactic of an elite-driven counter-movement designed to combat environmentalism, and that the successful use of this tactic has contributed to the weakening of US commitment to environmental protection.

Mounting Costs Slow the Push for Clean Coal

Sunday, June 15th, 2008

WASHINGTON — For years, scientists have had a straightforward idea for taming global warming. They want to take the carbon dioxide that spews from coal-burning power plants and pump it back into the ground.

President Bush is for it, and indeed has spent years talking up the virtues of “clean coal.” All three candidates to succeed him favor the approach. So do many other members of Congress. Coal companies are for it. Many environmentalists favor it. Utility executives are practically begging for the technology.

But it has become clear in recent months that the nation’s effort to develop the technique is lagging badly.

In January, the government canceled its support for what was supposed to be a showcase project, a plant at a carefully chosen site in Illinois where there was coal, access to the power grid, and soil underfoot that backers said could hold the carbon dioxide for eons.

Perhaps worse, in the last few months, utility projects in Florida, West Virginia, Ohio, Minnesota and Washington State that would have made it easier to capture carbon dioxide have all been canceled or thrown into regulatory limbo.

Coal is abundant and cheap, assuring that it will continue to be used. But the failure to start building, testing, tweaking and perfecting carbon capture and storage means that developing the technology may come too late to make coal compatible with limiting global warming.

“It’s a total mess,” said Daniel M. Kammen, director of the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley.

Global warming may be greatest threat to tropical species

Sunday, June 15th, 2008

Washington – While global warming is expected to be strongest at the poles, it may be an even greater threat to species living in the tropics, scientists say.

Tropical species are accustomed to living in a small temperature range and thus may be unable to cope with changes of even a few degrees, according to an analysis in Tuesday’s edition of Proceedings of the National Academy of Sciences.

“There’s a strong relationship between your physiology and the climate you live in. In the tropics many species appear to be living at or near their thermal optimum, a temperature that lets them thrive. But once temperature gets above the thermal optimum, fitness levels most likely decline quickly and there may not be much they can do about it,” Joshua J. Tewksbury said in a statement.

Worries Mount as Farmers Push for Big Harvest

Saturday, June 14th, 2008

GRIFFIN, Ind. — In a year when global harvests need to be excellent to ease the threat of pervasive food shortages, evidence is mounting that they will be average at best. Some farmers are starting to fear disaster.

American corn and soybean farmers are suffering from too much rain, while Australian wheat farmers have been plagued by drought.

“The planting has gotten off to a poor start,” said Bill Nelson, a Wachovia grains analyst. “The anxiety level is increasing.”

Randy Kron, whose family has been farming in the southwestern corner of Indiana for 135 years, should have corn more than a foot tall by now. But all spring it has seemed as if there were a faucet in the sky. The rain is regular, remorseless.

Some of Mr. Kron’s fields are too soggy to plant. Some of the corn he managed to get in has drowned, forcing him to replant. The seeds that survived are barely two inches high.

At a moment when the country’s corn should be flourishing, one plant in 10 has not even emerged from the ground, the Agriculture Department said Monday. Because corn planted late is more sensitive to heat damage in high summer, every day’s delay practically guarantees a lower yield at harvest.

National Academies call for 50% CO2 cut

Saturday, June 14th, 2008

The National Academies of 13 countries told the leaders of the biggest polluting countries that “immediate large-scale mitigation action is required.”

While objections have been raised by a few people (well, one person anyway) to these leading scientific groups inserting themselves into the climate debate, the rest of us should be glad they are counseling the world — especially their own countries — toward sanity. The statement is clear on what actions will be needed:

The transition to a low carbon society requires: setting standards; designing economic instruments and promoting energy efficiency across all sectors; encouraging changes in individual behaviour; strengthening technology transfer to enable leapfrogging to cleaner and more efficient technologies; and investing strongly in carbon-removing technologies and low-carbon energy resources: nuclear power, solar energy, hydroelectricity and other renewable energy sources.

Hints of methane’s renewed rise

Wednesday, June 11th, 2008

– And why would a rise in Methane levels be important?:

“Methane is the second most important gas causing man-made climate change. Each molecule causes about 25 times more warming than a molecule of CO2, but it survives for shorter times in the atmosphere before being broken down.”

 – As the world’s temperature rises, vast amounts of Methane trapped in the permafrost will be released as the permafrost melts.   In addition, there are vast amounts of Methane trapped in deep ocean sediments as Methane Clathrates and scientists fear that given sufficient warming of the oceans, these will be released into the atmosphere as well.   More warming, more releases, more releases, more warming.   It’s not a pretty picture.

– – – – – – – – – – – – –

Levels of the greenhouse gas methane in the atmosphere seem to be rising having remained stable for nearly 10 years.

Data from the National Oceanographic and Atmospheric Administration (Noaa) in the US suggest concentrations rose by about 0.5% between 2006 and 2007.

The rise could reflect melting of permafrost, increased industrialisation in Asia or drying of tropical wetlands.

The rise in carbon dioxide levels was significantly higher than the average annual increase for the last 30 years.

Noaa figures show CO2 concentrations rising by 2.4 parts per million (ppm) from 2006 to 2007. By comparison, the average annual increase between 1979 and 2007 was 1.65ppm.

Concentrations now stand at 384 ppm, compared to about 280 ppm before the era of human industrialisation began

Upwards curve?

The rise in CO2 is not exceptional compared with the previous few years, but does add more evidence that concentrations are rising faster than they were a decade or so ago.

The methane figure is more interesting, and potentially of more concern.

Concentrations have been more or less stable since about 1999 following years of rapid increases. Industrial reform in the former Soviet bloc, changes to rice farming methods and the capture of methane from landfill sites all contributed to the levelling off.

But the 2007 figure indicates that levels may be on the rise again.

US climate change bill is blocked

Wednesday, June 11th, 2008

– “It’s a huge tax increase,” said Mitch McConnell, leader of the Senate Republicans, most of whom opposed the bill.

-Mmmm- what a great reason to put off saving the world from catastrophe.   Bravo. 

= = = = =

A US attempt to establish a system of caps and tax relief to cut carbon emissions has been blocked in Congress.

The bill was backed by most senators, but did not get the 60 votes needed to stop a delaying tactic – a filibuster – used by the bill’s opponents.

Even if it had succeeded in passing Congress, President George W Bush had pledged to veto the bill.

Lawmakers will now wait until next year – when there will be a new president – before attempting to pass a new bill.

Doomed Kiribati needs escape plan

Wednesday, June 11th, 2008

Kiribati’s President, Anote Tong, says his country may already be doomed by global warming – and he wants New Zealand and Australia to consider the issue of environmental refugees.

“We may already be at the point of no return, where the emissions in the atmosphere will carry on contributing to climate change, so in time our small low-lying islands will be submerged,” Mr Tong said yesterday in Wellington.

Kiribati’s highest point of land is just 2m above sea level, and under “worst-case” scenarios it will be flooded by the Pacific this century and its 94,000 people will have to be re-settled in other countries.

Mr Tong, a graduate of the London School of Economics, said climate change “is not an issue of economic development, it’s an issue of human survival”.

Climate Findings Were Distorted, Probe Finds

Wednesday, June 4th, 2008

– If you are not angry – you are not paying attention. 

= = = = =

An investigation by the NASA inspector general found that political appointees in the space agency’s public affairs office worked to control and distort public accounts of its researchers’ findings about climate change for at least two years, the inspector general’s office said yesterday.

The probe came at the request of 14 senators after The Washington Post and other news outlets reported in 2006 that Bush administration officials had monitored and impeded communications between NASA climate scientists and reporters.

James E. Hansen, who directs NASA’s Goddard Institute for Space Studies and has campaigned publicly for more stringent limits on greenhouse gases that contribute to global warming, told The Post and the New York Times in September 2006 that he had been censored by NASA press officers, and several other agency climate scientists reported similar experiences. NASA and the National Oceanic and Atmospheric Administration are two of the government’s lead agencies on climate change issues.

From the fall of 2004 through 2006, the report said, NASA’s public affairs office “managed the topic of climate change in a manner that reduced, marginalized, or mischaracterized climate change science made available to the general public.” It noted elsewhere that “news releases in the areas of climate change suffered from inaccuracy, factual insufficiency, and scientific dilution.”

Officials of the Office of Public Affairs told investigators that they regulated communication by NASA scientists for technical rather than political reasons, but the report found “by a preponderance of the evidence, that the claims of inappropriate political interference made by the climate change scientists and career public affairs officers were more persuasive than the arguments of the senior public affairs officials that their actions were due to the volume and poor quality of the draft news releases.”
