Actually, "global warming" is a term that does refer to the warming of the near surface air (and water) temperatures -- but what many people seem to overlook is the "global" part of the term -- it refers to the average temperature of the planet, rather than in localized regions. One predicted effect of this trend of global warming is more extreme weather events (including more extreme highs and lows). "Climate change" probably makes more sense to use because of those many who focus on any extreme of cold weather as somehow negating the fact that the global average temperatures have been increasing at an unprecedented rate in the past century. And that is all that I have to say about global warming in this non-PI thread.
