summing up global warming......

........as heard last night on coast to coast radio. cannot recall the name of the guest--i tuned in late and only listened for about 15 minutes. the discussion at the moment was global warming, the on-going debates people and the science community engage in--is it a natural cycle or is it human caused. as this guest said, it doesn't matter at this point. he nailed it when he said "the air is a mess. we need to clean it up."
