The row over US inaction on carbon emissions reached new heights yesterday after the White House allowed Congress to look at last year's government proposal to officially deem climate change a threat to public health - a plan that aides to George Bush refused to acknowledge or read. The climate plan was finished in December by the US Environmental Protection Agency (EPA) in response to a supreme court ruling that required the Bush administration to state whether carbon emissions should be regulated to protect public health.

A new study shows that Germany has already reduced greenhouse gas emissions to the level pledged in the Kyoto Protocol. But a greater reliance on coal-fired power plants may soon reverse the trend. When it comes to global warming and concurrent efforts to reduce the emissions of greenhouse gases, Germany has always tried to present itself as a leader. New data set to be released on Friday shows that the country has earned its bragging rights.

Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.

Researchers developing alternatives to fossil fuels are working with everything from algae to babassu oil to corn, but a California company says it can recycle carbon dioxide into fuel. Carbon Sciences claims it has developed a way of using the CO2 emitted during the combustion of coal, oil and other hydrocarbons to create transportation fuels like gasoline and jet fuel. Should Carbon Sciences - or any of the other firms working on similar projects - accomplish this on a large scale, it could bring a reduction in CO2 emissions as well as an abundant supply of renewable fuel.

Concerns over the destruction of the Brazilian rainforest resurfaced at the weekend after it emerged that deforestation jumped by 64% over the last 12 months, according to official government data. Brazil's National Institute for Space Research this week said that around 3,145 square miles - an area half the size of Wales - were razed between August 2007 and August 2008.

What if it were possible to bury carbon dioxide over a mile below a power plant in the second worst air basin in the United States? In 2011 the greenhouse gas will be pumped below a power plant in the southern San Joaquin Valley of California. Located in Kern County near Bakersfield, the Clean Energy Systems power plant is powered by different kinds of natural gas and oxygen. It produces five megawatts of energy, enough for 5,000 homes, but the carbon sequestration experiment will increase that to 50 megawatts.

Australia is the dryest nation on earth, always was always will be, the trouble is Global warming is making the situation worse and rainfall is reducing in a disturbing pattern. For two centuries since European settlement the States have fought over 'Water-Right's' and the use of water to the detriment of the environment and ultimately to the sustainability of everyone residing here. The Murray-Darling Basin is 3,370km long, drains one-seventh of the Australian land mass, and is currently by far the most significant agricultural area in Australia. The name of the basin is derived from its two major rivers, the Murray River and the Darling River.

In an interview released today by Newsmax, Gov. Sarah Palin (R-AK) - Sen. John McCain's (R-AZ) newly minted running mate - was asked for her "take on global warming and how is it affecting our country." "A changing environment will affect Alaska more than any other state, because of our location," Palin said, adding, "I'm not one though who would attribute it to being man-made." DeSmogBlog notes that NASA and the National Academy of Sciences disagree:

Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. The animation above is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced Synthetic Aperture Radar (ASAR) instrument aboard Envisat. The dark grey colour represents ice-free areas while blue represents areas covered with sea ice.

New satellite measurements show that crucial sea ice in the Arctic Ocean has plummeted to its second-lowest level on record. Arctic ice always melts in summer and refreezes in winter. But more and more ice is being lost and not recovered. The National Snow and Ice Data Center in Boulder, Colorado, announced Wednesday that the extent of sea ice in the Arctic is down to 2.03 million square miles. The lowest point on record is 1.65 million square miles set last September. With about three weeks left in the melt season, the record may fall, scientists say.

As soon as I have finished this column I will jump on the train to Kent. Last year Al Gore remarked: "I can't understand why there aren't rings of young people blocking bulldozers and preventing them from constructing coal-fired power plants." Like hundreds of honorary young people, I am casting my Zimmer frame aside to answer the call. Everything now hinges on stopping coal. Whether we prevent runaway climate change largely depends on whether we keep using the most carbon-intensive fossil fuel. Unless we either leave it - or the carbon dioxide it produces - in the ground, human development will start spiralling backwards. The more coal is burnt, the smaller are our chances of future comfort and prosperity. The industrial revolution has gone into reverse.

The first meeting of the International Agrichar Initiative convened about 100 scientists, policymakers, farmers and investors with the goal of birthing an entire new industry to produce a biofuel that goes beyond carbon neutral and is actually carbon negative. The industry could provide a "wedge" of carbon reduction amounting to a minimum of ten percent of world emissions and possibly much more.

When the tobacco industry was feeling the heat from scientists who showed that smoking caused cancer, it took decisive action. It engaged in a decades-long public relations campaign to undermine the medical research and discredit the scientists. The aim was not to prove tobacco harmless but to cast doubt on the science.

According to a study published in the July 14, 2000, issue of Science, one-third of the world's population is water-stressed, with 8 percent classified as severely water-stressed, including the western United States and northern Mexico, South America, India, China, Africa surrounding the Sahara Desert, and southern Africa and Australia. "Water stress" has profoundly different meanings in developed and developing countries. In Africa and many parts of Asia, it means inadequate water for drinking, sanitation and crops. In emerging economies such as India and China, it translates as an inability to meet the dietary and lifestyle aspirations of a growing middle class.

(NaturalNews) Scientists have increasingly warned that a hasty switch from fossil fuels to biofuels may actually accelerate global warming rather than helping to avert it, leading U.K. Prime Minister Gordon Brown to declare his opposition to new European Union biofuel standards that will soon be going into effect.

This map is from the August 2008 "Humanitarian Implications of Climate Change" report, commissioned by U.N. OCHA and CARE. It shows cumulative humanitarian risk hotspots for all three climate-related hazards studied - floods, cyclones and drought. Areas at risk of more than one type of hazard are considered to be of most concern for humanitarian actors.

New greenhouse gases emitted in making flat-screen televisions or some refrigerants might be capped under a planned U.N. treaty to combat global warming, delegates at U.N. talks in Ghana said on Friday. Emissions of the recently developed industrial gases, including nitrogen trifluoride and fluorinated ethers, are estimated at just 0.3 percent of emissions of conventional greenhouse gases by rich nations. But the emissions are surging.

WASHINGTON (May 29, 2008) - More than 1,700 of the nation's most prominent scientists and economists today released a joint statement calling on policymakers to require immediate, deep reductions in heat-trapping emissions that cause global warming. Issued just days before the Senate begins debate on the Lieberman-Warner climate bill, the statement marks the first time leading U.S. scientists and economists have joined together to make such an appeal.

James Hansen, one of the world's leading climate scientists, will today call for the chief executives of large fossil fuel companies to be put on trial for high crimes against humanity and nature, accusing them of actively spreading doubt about global warming in the same way that tobacco companies blurred the links between smoking and cancer.

A four-square-kilometre chunk has broken off Ward Hunt Ice Shelf - the largest remaining ice shelf in the Arctic - threatening the future of the giant frozen mass that northern explorers have used for years as the starting point for their treks. Scientists say the break, the largest on record since 2005, is the latest indication that climate change is forcing the drastic reshaping of the Arctic coastline, where 9,000 square kilometres of ice have been whittled down to less than 1,000 over the past century, and are only showing signs of decreasing further.
