A telling sign of climate change is the declining amount of Arctic sea ice that remains at the end of summer. And it's not just an indicator. Arctic ice also influences climate by cooling the planet.
You can follow changes in sea-ice status at the Web site of the National Snow and Ice Data Center in Boulder, Colorado, which posts regular updates on ice conditions and analyses of trends. By mid-August, this year's melt had already broken the record set in 2005, when only 5.3 million square kilometers of ice were left at the end of the season, 31% below average. The site will provide fresh information until the melting halts, usually in September.

Some parts of the world pump more carbon dioxide into the atmosphere than they remove, whereas other regions are net absorbers. A new site for charting the ups and downs of the greenhouse gas is CarbonTracker from the U.S. National Oceanic and Atmospheric Administration in Boulder, Colorado.
CarbonTracker incorporates CO2 measurements from some 60 locations around the world to provide a broad picture of carbon uptake and release for North America, the globe, and the oceans between 2000 and 2005. Visitors can also check out the "carbon weather" to see how storms alter levels of the gas. The researchers hope other labs will contribute data that could help make CarbonTracker an objective tool for gauging whether carbon emission targets are being met.

Letterman's become a real politico lately... Aside from this video, he's made some serious jabs at McCain's campaign. FYI, Obama is on his show tonight!

He also said he didn't think that little steps like reusing party toothpicks or turning lawn clippings into mulch could possibly help.
