We are all familiar with climate change: the biggest change occurs between the summer and the winter. This change occurs in most places in addition to any change due to greenhouse gases or the earth's orbital parameters.

From page 29... ...
We know that atmospheric carbon dioxide concentrations will increase and will continue to increase as long as we use fossil fuels and as long as we persist in cutting down our tropical forests. At least in principle, we know what we can do about carbon dioxide: we could cut down on the use of fossil fuels and we could grow trees instead of cutting them down.

From page 30... ...
In any case, the concentration of carbon dioxide in the atmosphere will not increase indefinitely, because we will ultimately exhaust the world's reserves of fossil fuels. A quadrupling of atmospheric carbon dioxide compared to mid-nineteenth century levels would be about the highest atmospheric concentration that could be expected in the future and could possibly occur in the twenty-second century.
