The evidence for the increase in global temperature and the indications that it is manmade are about as scientifically certain as to whether or not the sun will rise tomorrow. This will change our planet. It will not end life here, but it will become more difficult for many people. The worst effects will happen beyond my lifetime, and some may well be catastrophic to people and unforeseen. Using less polluting foms of energy and production seems sensible(why would you pay to make pollution? For that is what inefficient industries do when they pollute). Still we will not be able to duck the effects of what we have set in motion. However, we can look at how we can cope with these changes. Sadly, many people, especially in Africa, the Indian sub-continent and much of Central asia will suffer both from flooding due to sea level rise, and drought due diminished rain fall and diminished glacial run off as the glaciers in the Himalayas shrink.

The St.Lawrence river, flowing from the Great Lakes to the Atlantic ocean can sustain the cities on it, as long as they do not grow substantially bigger, although its water level has declined, partially because most of the water taken by Toronto, Montreal and Quebec is used, treated and returned to the river.
