Global warming could be far worse than predicted, new study suggests
Collapsing polar ice caps, a green Sahara Desert, a 20-foot sea-level rise. That's the potential future of Earth, a new study suggests, noting that global warming could be twice as warm as current climate models predict. The rate of warming is also remarkable: “The changes we see today are much faster than anything encountered in Earth’s history. In terms of rate of change, we are in uncharted waters,” said study co-author Katrin Meissner of the University of New South Wales in Australia.
