Document Summary

Oct 31st long term carbon cycles and climate patterns mean we will remove all of it in a short time because it is replenished automatically. We are taking co2 from long-term carbon cycle and transferring it into the short- Reservoir times of water vapor in atmosphere are very short. This is the fundamental problem we"re having atm. Long-term patterns are referred to as (cid:498)rhythms(cid:499) and (cid:498)trends(cid:499). into short-term cycle faster than it can be removed. Patterns of variation in atmospheric carbon can be measured on a number of time scales. Where you have a lot of geologic, volcanic activity, etc. Potential sources for outgassing of carbon dioxide (tectonic plate lines in oceans and land) Sub ducting borders: oceanic and continental plates running into each other, and sinking (sub ducting), releases co2. Spreading plate: where continents are drifting apart, creating new land. They allow for transfer co2 that is trapped in the rocks to the atmosphere.
