Good article containing section on atmospheric CO2 and history. Levels seem to be growing at about 2 ppmv (parts per million by volume) each year as a trend (though we have seasonal fluctuations of 6 ppmv due to plant growth).

Net increase of 110 ppmv since the Industrial Revolution. Since the atmosphere's CO2 composition is now at 383 ppmv, about 1/4 of it can be attributed to man-made sources.

In the last 400,000 years, the earth has "naturally" swung between 200 and 300 ppmv. But if you go back into the 100's of millions of years, we had levels above 2000 ppmv.

Check out how much carbon dioxide your car emits a year. I drive a Mazda 3, which , by comparison, is not a "gaz guzzler". But because of my daily commute from Fremont to Boeing plants in Everett, Renton, and Bellevue, (30 miles + seattle traffic) it's technically a gaz guzzler.

Quoted: TerraPass allows consumers to easily and affordably eliminate the environmental impact of driving their cars by purchasing carbon emission offsets. Help prevent global warming. TerraPass is a global warming solution that reduces carbon dioxide air pollution. Your car puts several tons of carbon dioxide into the air every year. TerraPass takes it back out. Easy, effective, affordable.

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!

Quoted: "We are dead meat," said David Letterman last night in the midst of a lengthy rant on global warming. He blamed a lack of leadership over the last several decades. He also said he didn't think that little steps like reusing party toothpicks or turning lawn clippings into mulch could possibly help.

ok, here I am asking a question of Gov Gregoire and Candidate Dino Rossi in the WA state governor's race. please go to youtube and watch the video and give it a good rating so that it's picked as one of the final 5! (and make fun of me later...) Even if you don't live in the state, you can still vote on the video :-)

Quoted: Sudha, from Spokane asks: Do you believe that global warming is caused by human activities? If so, do you support science based and enforceable caps to limit...

Apparently if you don't like something, you can ignore it by just not opening the email.

Quoted: The White House told E.P.A. officials that it would not open an e-mail sent in December that argued that greenhouse gases are pollutants that must be controlled.

Now I'm even more curious to see this movie...

Quoted: Pixar's new animated feature Wall-E is more than a great movie. According to the critics, it's a trenchant social commentary. So what is this powerful and profound message? Wall-E tells us that if we don't change the way we live, we'll all get really fat and destroy the world.

Quoted: The disappearance of the Arctic sea ice, making it possible to reach the Pole sailing in a boat through open water, would be one of the most dramatic – and worrying – examples of the impact of global warming on the planet. Scientists say the ice at 90 degrees north may well have melted away by the summer.

Quoted: First, global warming lacks a mustache. No, really. We are social mammals whose brains are highly specialized for thinking about others. Understanding what others are up to — what they know and want, what they are doing and planning — has been so crucial to the survival of our species that our brains have developed an obsession with all things human. We think about people and their intentions; talk about them; look for and remember them.
