White House report notes apparent effects
WASHINGTON - Harmful effects from global warming are already here and worsening, warns the first climate report from Barack Obama’s presidency in the strongest language on climate change ever to come out of the White House.
Global warming has already caused more heavy downpours, the rise of temperatures and sea levels, rapidly retreating glaciers, and altered river flows, according to the document released yesterday by the White House science adviser and other top officials.
“There are in some cases already serious consequences,’’ report coauthor Anthony Janetos of the University of Maryland told the Associated Press. “This is not a theoretical thing that will happen 50 years from now. Things are happening now.’’
The White House document - a climate status report required periodically by Congress - contains no new research. But it paints a fuller and darker picture of global warming in the United States than previous studies and brief updates during the George W. Bush years. Bush was ultimately forced by a lawsuit to issue a draft report last year, and that document was the basis for this new one.

For example, parts of Texas that recently experienced about 10 to 20 days per year over 100°F are expected to experience more than 100 days per year in which the temperature exceeds 100°F by the end of the century under the higher emissions scenario.
