Long Droughts, Rising Seas Predicted Despite Future CO2 Curbs
Washington Post (27th Jan) – Greenhouse gas levels currently expected by mid-century will produce devastating long-term droughts and a sea-level rise that will persist for 1,000 years regardless of how well the world curbs future emissions of carbon dioxide, an international team of scientists reported yesterday.
Top climate researchers from the U.S. National Oceanic and Atmospheric Administration, Switzerland and France said their analysis shows that carbon dioxide will remain near peak levels in the atmosphere far longer than other greenhouse gases, which dissipate relatively quickly.
“I think you have to think about this stuff as more like nuclear waste than acid rain: The more we add, the worse off we’ll be,” NOAA senior scientist Susan Solomon told reporters in a conference call. “The more time that we take to make decisions about carbon dioxide, the more irreversible climate change we’ll be locked into.” (Read More)
Report: Some climate damage already irreversible
Associated Press (27th Jan)– Many damaging effects of climate change are already basically irreversible, researchers declared Monday, warning that even if carbon emissions can somehow be halted temperatures around the globe will remain high until at least the year 3000.
“People have imagined that if we stopped emitting carbon dioxide the climate would go back to normal in 100 years, 200 years; that’s not true,” climate researcher Susan Solomon said in a teleconference.
Solomon, of the National Oceanic and Atmospheric Administration’s Earth System Research Laboratory in Boulder, Colo., is lead author of an international team’s paper reporting irreversible damage from climate change, being published in Tuesday’s edition of Proceedings of the National Academy of Sciences.
