Global warming impacts have sped up

USATODAY.com : Since the 1997 international Kyoto accord to fight global warming, climate change has worsened and accelerated—beyond some of the grimmest of warnings made back then.In Greenland and Antarctica, ice sheets have lost trillions of tons of ice. Mountain glaciers in Europe, South America, Asia, and Africa are shrinking faster than before.And it’s not just the frozen parts of the world that have felt the heat:The world’s oceans have risen by about an inch and a half.Droughts and wildfires have turned more severe worldwide.Temperatures over the past 12 years are 0.4 of a degree warmer than the dozen years leading up to 1997.Even the gloomiest climate models back in the 1990s didn’t forecast results quite this bad so fast."The latest science is telling us we are in more trouble than we thought,” said Janos Pasztor, climate adviser to UN Secretary General Ban Ki-moon.
