Rob Quinn, Newser: A recent United Nations report warned that the world had just a dozen years left to avoid some of the most catastrophic effects of climate change. A new study suggests that assessment was far too optimistic. Researchers using a new method to calculate the amount of heat absorbed by the world's oceans say the buildup of heat over the last 25 years is 60% higher than previous estimates, meaning the world is warming significantly faster than expected, the BBC reports.

How many will stop dead in their tracks to stop using fossil fuels? Can the world be saved?
