Volume 65, Issue 3

cover: Historically bad weather plagued the US last year: Hurricane Irene caused major flooding in the Northeast, powerful tornadoes ravaged the Midwest and Southeast, and prolonged drought led to one of the harshest fire seasons on record in the Southwest. In the article on page 31, the National Oceanic and Atmospheric Administration’s Jane Lubchenco and Thomas Karl write that 2011 continues a decades-long trend toward warmer climate and wilder weather.
