Scientists set to lay out plan to head off worst of climate changes

Tuesday, April 24, 2007

BANGKOK, Thailand -- U.N.-sponsored scientists who warned of the dangers of a warming Earth will issue a new study next month describing how to avert the worst: Everyone must embrace technologies ranging from nuclear power to manure control.

Under a best-case scenario for heading off severe damage, the global economy might lose as little as 3 percentage points of growth by 2030 in deploying technologies to reduce greenhouse-gas emissions, says the panel's draft report, obtained by The Associated Press.

"Governments, businesses and individuals all need to be pulling in the same direction," said British researcher Rachel Warren, one of the report's authors.

The draft report from the Intergovernmental Panel on Climate Change, whose final version is to be issued May 4 in Bangkok, says emissions can be cut below current levels if the world shifts away from carbon-heavy fuels like coal, embraces energy efficiency and significantly reduces deforestation.

The draft notes that significant cuts could come from making buildings more energy-efficient, especially in the developing world, through better insulation, lighting and other steps, and by converting from coal to natural gas, nuclear power and renewable energy such as wind, solar and biofuels.

Also important would be making motor vehicles more fuel-efficient and reducing deforestation. Even capturing methane emitted by livestock and its manure would help, the report says.
