  • Sea-Level Rise Too Fast to Reverse Climate Change: Study

    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.

  • Hansen Says Tar-Sands Oil Makes Climate Change Unsolvable

    Exploiting oil and gas trapped in tar sands and shale threatens to make climate change “unsolvable,” said James Hansen, the former NASA scientist who raised concerns about global warming in the 1980s.

  • Climate Scientist Hansen Turns Activist, Advocates 'Fee' on Carbon Pollution

    James Hansen, the former NASA climate scientist who first brought climate change to the attention of Congress in the 1980s, stepped down as head of the agency's Goddard Institute for Space Studies last month. That hasn’t stopped him traveling the globe to lobby for climate protection measures, while remaining an adjunct professor for Earth and Environmental Studies at Columbia University.

  • James Hansen Says Greenland Melt May Cool North Atlantic

    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.

  • Recent Heat Waves Caused by Global Warming, Hansen Says

    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.

  • NASA’s Hansen Arrested Outside White House at Pipeline Protest

    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.

  • Recent Heat Waves Caused by Global Warming, Hansen Says

    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.

  • Keystone XL Will Not Use Advanced Spill Protection Tech

    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.

  • Carbon Price Needed to Halt Warming, NASA Chief Says

    Putting a price on carbon is the world’s best hope at staving off runaway global warming, said James Hansen, the top climate-change scientist at the U.S. National Aeronautics and Space Administration.

  • Keystone Pipeline Foes Should Face Reality

    Opponents of the Keystone XL oil pipeline warn of its potentially catastrophic consequences. Building it, climate scientist James Hansen says, would mean “game over” for the climate.
