Last I heard is that the new buzz word is climate change.  I'm guessing that there wasn't enough factual data to predict that the Earth was actually heating at an alarming rate.  If the climate is changing, isn't is possible that it could start heading in a cooling direction.   Shouldn't we start researching for ways that we could survive based on both scenarios should our predictions turn out wrong.  I feel the efforts of man to control the Earth significantly pale in comparison to our Creator. All this spending of resources may be a total waste.
