Greenhouse gas emissions from power stations could be cut to almost zero by controlling the combustion process with tiny tubes made from an advanced ceramic material, claim engineers today (3 August 2007).

United Nations Secretary-General Ban Ki-moon urged the United States to take the lead in combating global warming during a visit to California to learn about the state's aggressive campaign to curb its greenhouse gas emissions.

Farmers will be the first to feel the heat from global warming as they grapple with new and aggressive crop pests, summer heat stress and other sobering challenges that could strain family farms to the limit, warns David Wolfe, a Cornell expert on the effects of climate change on agriculture.

Please do your homework before CO2-Climate-Change costs you your economies.

Most Americans now believe that global warming is happening, and they want the federal government to take action to limit its effects. But what form should that action take" And does support for action hold firm if people understand how much it may cost them financially"

Gov. Arnold Schwarzenegger will travel to London on Sunday, two days before British Prime Minister Tony Blair leaves office, to reciprocate a visit Blair made to California.

A study led by a Purdue University researcher projects a 200 percent to 500 percent increase in the number of dangerously hot days in the Mediterranean by the end of the 21st century if the current rate of greenhouse gas emissions continues. The study found France would be subjected to the largest projected increase of high-temperature extremes.

Leaders of the eight largest industrialized nations - or G-8 - agreed last week in Heilingendamm, Germany, to join forces to make "substantial" - but unspecified - cuts in greenhouse gas emissions. At President Bush's insistence, the G-8 did not impose binding targets for the reductions.

Tony Blair hopes that the Group of Eight would agree on a "substantial reduction" in long-term greenhouse gas emissions despite U.S.-European disagreement over binding cuts.

Land conversion and climate change have already had significant impacts on biodiversity and associated ecosystem services.Using future land-cover projections from the recently completed Millennium Ecosystem Assessment, Walter Jetz, David Wilcove, and Andrew Dobson have now evaluated how all of the world's 8,750 species of land birds may be affected by environmental change.

UN Secretary-General Ban Ki-moon today praised a call by the United States for a summit of the countries that have the world's biggest emissions of greenhouse gases to discuss the growing threat posed by climate change.

Asia must increase renewable energy use, improve coal-fired power plant efficiency and switch to biofuels to reduce a quarter of their greenhouse gas emissions by 2030, a U.S. government report said Tuesday.
