Modeling atmospheric O2 over Phanerozoic time.

A coupled climate-economy calculation illustrate the extreme influence of economic discounting in some sampled projections that come from our own, slightly-modified version of the DICE model.

Only after thousands of years will this carbon be nearly totally rid of, and at that point the effects of it might already be too late to reverse.

Cogeneration or combined heat and power CHP is the use of a or to and at the same time.

However, warmer temperatures also stress plants.

Additional buffering capacity is available in the form of carbonate sediments that lie far below the surface, on the ocean floor.

The known coal reserves contain more than five times as much carbon as is now in the air--and it is the burning of these large stores in years to come that could lead to the very large increases in atmospheric CO 2 and surface temperature that were cited here.

Partly expanded steam is then condensed in a heating condensor at a temperature level that is suitable e.
