worse than we thought – tropical forests ignited!

Without decisive action, global warming is likely to accelerate at a much faster pace and cause more environmental damage than predicted, says Stanford scientist Chris Field, a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change.

Field warns that higher temperatures could ignite tropical forests and melt the Arctic tundra, releasing billions of tons of greenhouse gas that could raise temperatures even more — a vicious cycle that could spiral out of control.
