North America experienced both brutal drought and a record-setting storm. Extreme weather in Africa, southeast Asia and Europe also caused widespread damage and cost many lives. In fact, as New York state governor Andrew Cuomo noted, extreme weather seems to be the "new normal".With delegates from around the world converging on Doha, Qatar, this week for the 18th UN conference on climate change (COP18), the need for real progress on global warming has never been more urgent. And while there are many obstacles to progress on this crucial problem, there are hopeful signs as well.

For example, rising sea levels in the Northeast, which are increasing three to four times faster than global rates, according to federal statistics, will bring more flooding and damaging storm surges that ride atop high seas. Warmer air can hold more water vapor, meaning storms could drop more precipitation. New England has seen more erratic precipitation in recent years with extreme rain and snowfall events increasing by 85 percent since 1948, according to a climate report issued last week by US Representative Ed Markey, called “The New New England.”
