The record heat wave and drought tormenting much of the U.S. is part of a “new extreme category” of weather that is most likely the result of global warming, a top U.S. government climate scientist said.
Greenland ice melting at an expanding pace may begin cooling the North Atlantic and increasing the severity of storms by 2075, said James Hansen, the former NASA scientist who raised concerns about global warming in the 1980s.
James Hansen, head of NASA’s Goddard Institute for Space Studies, was arrested outside the White House as he joined protesters in urging President Barack Obama to reject TransCanada Corp.’s $7 billion pipeline.
The drought in Texas last year, the heat wave in Russia in 2010 are among weather extremes that “certainly would not have occurred” without global warming, according to a paper by a U.S. government climate scientist.
By the time climate change reduces crop yields or frequently floods New York City subways, it would be too late to avert damage without better forecasting tools, a panel of scientists said in a report released today.
InsideClimateNews.org -- In 1998, activists in Austin, Texas filed a lawsuit to protect their local aquifer from a proposed gasoline pipeline. By the time the project was built, the operator had been forced to add $60 million in safety features, including sensor cables that could detect leaks as small as three gallons a day. Some say the Longhorn pipeline is the safest pipeline in Texas, or perhaps the nation.
The global temperature this year reached its warmest on record based on a 12-month-rolling average, James Hansen , the top climate change scientist at the U.S. National Aeronautics and Space Administration, said today.
