Should we try to totally eliminate the greenhouse effect?
Even if it were possible, we should not try to eliminate the greenhouse effect entirely - the result would be for temperatures to fall well below freezing and make it difficult for humans to survive. We need the natural greenhouse effect that keeps the world at a comfortable temperature suitable for human existence. It is probably too late now to eliminate the enhanced greenhouse effect resulting from two centuries of human activities that poured carbon dioxide and methane into the atmosphere. What we can and should do is to begin now to reduce our further emissions of greenhouse gaes, so that later in this century we can eliminate any anthropogenic addition to the greenhgouse effect.
