Bridging the Gap between Climate and Weather
The distinction between climate and weather was expressed most succinctly by science fiction writer Robert A. Heinlein: “Climate is what you expect; weather is what you get.” But as global warming produces more noticeable changes on a planetary scale, how do we even know what to expect in a particular region?

Breeding Bigger Hurricanes
Greenhouse gases are linked to growing intensity of tropical storms
Rising ocean temperatures in key hurricane breeding grounds of the Atlantic and Pacific oceans are due primarily to human-caused increases in greenhouse gas concentrations, according to a recent study.
Using 22 different computer models of the climate system, researchers have shown that the warming sea surface temperatures (SSTs) of the tropical Atlantic and Pacific oceans over the last century are linked to human activities. Research published during the past year has uncovered evidence of a link between rising ocean temperatures and increases in hurricane intensity.
