Earth's climate could be approaching dangerous point

NASA and Columbia University Earth Institute research finds that greenhouse gases bring dangerous consequences to Earth's climate.

From a combination of climate models, satellite data, and paleoclimate records, the scientists conclude that the West Antarctic ice sheet, Arctic ice cover, and regions providing fresh water sources and species habitat are under threat from continued global warming.

Tipping points can occur during climate change when the climate reaches a state such that strong amplifying feedbacks are activated by only moderate additional warming. This study finds that global warming of 0.6
