Faster CO2 increases Carbon Dioxide in Atmosphere Increasing By THE ASSOCIATED PRESS Filed at 10:16 p.m. ET October 22, 2007 NYTimes WASHINGTON (AP) -- Just days after the Nobel prize was awarded for global warming work, an alarming new study finds that carbon dioxide in the atmosphere is increasing faster than expected.Nobel prizeglobal warming Carbon dioxide emissions were 35 percent higher in 2006 than in 1990, a much faster growth rate than anticipated, researchers led by Josep G. Canadell, of Australia's Commonwealth Scientific and Industrial Research Organization, report in Tuesday's edition of Proceedings of the National Academy of Sciences. Proceedings of the National Academy of Sciences

Weather Hot Air Rises Coriolis Force bends moving things to the right in the northern hemisphere Cold air holds less water Air moves from areas of high pressure to areas of low pressure

Hot Air Rises Air can hold less water at higher altitudes 1. Hot air rises over land due to heating by the sun. 2. The rising air leaves less air in one spot, low pressure forms. 3. Generally, from 3,000 to 5,000 feet, the air cools, high pressure develops. 4. Meanwhile, over the cooler water, air sinks, leaving less air aloft. 5. More air piles up at the surface of the water, high pressure forms. 6. Air moves from high pressure to low pressure. 7. The sea breeze generally forms during the afternoon. This creates a mini cold front that helps lift air upward to create thunderstorms.
