MacDougall may point out these facts but whilst doing so he refrains from the typical alarmism that often accompanies these tracts. It is unlikely that Earth will be (as per many of the alarmists) transformed into another melting Venus, and the oceans can still absorb much of the CO2 that we are creating, although MacDougall does admit that we are destroying hordes of the marine population at the same time. He also says that our ability to release carbon emission into the atmosphere will decrease with time since our known oil deposits are rapidly dwindling.

Earth has already experienced one interglacial warming period; the extra carbon in the atmosphere aggravates the situation. Earth too is impeded form reflecting the sun's energy back into space due to the constant melting of the polar ice caps and other glaciers, thus the warming is accelerated and intensified.

The last 20,000 years have been uncommonly mild according to MacDougall's description. His prediction is that the next 20,000 to 30,000 years will see a steady warming trend before the earth begins to cool and reverses the effects of the...

It explains the crucial aspects of our Earth and the matters that concern each of us without repelling us by shrill and emotional ad hominem slaughter.
MacDougall shows us the facts as they are and by so doing gives us a clearer understanding of the issues of global warming and the climate making us more informed and concerned citizens through a greater knowledge of the underlying scientific facts.

"Why Geology Matters" is a book that is simultaneously readable and informative and probably will do far more in making us care about the universe than many a hell-filled other book on that same subject would do.
