WASHINGTON (Reuters) - Even if people stopped pumping out carbon dioxide and other pollutants tomorrow, global warming would still get worse, two teams of researchers reported on Thursday.
Sea levels will rise more than they have already risen, worsening the damage caused by extreme high tides and storm surges, and droughts, heat waves and storms will become more severe, the climate experts predicted.
That makes immediate action to slow global warming even more vital, the teams at the National Center for Atmospheric Research in Colorado report in the journal Science.
"Even if we stabilize greenhouse gas concentrations, the climate will continue to warm, and there will be proportionately even more sea level rise," said the NCAR's Gerald Meehl, who led one of the two studies.
"The longer we wait, the more climate change we are committed to in the future."
Virtually no one disagrees human activity is fueling global warming, and a global treaty signed in Kyoto, Japan, aims to reduce polluting emissions. But the world's biggest polluter, the United States, has withdrawn from the 1997 treaty, saying its provisions would hurt the U.S. economy.
