Clear synopsis of a recent UN report by Justin Gillis at the New York Times:

Nations have so dragged their feet in battling climate change that the situation has grown critical and the risk of severe economic disruption is rising, according to a draft United Nations report. Another 15 years of failure to limit carbon emissions could make the problem virtually impossible to solve with current technologies, experts found.

This issue has also been discussed in the Sunday Review section of the New York Times as well as the Los Angeles Times.
