I think we could do with some evidence that this is a real concept. Global warming aside, human impacts on the environment are almost exclusively local or regional, not global, AFAIK. Rd232 12:47, 31 July 2005 (UTC)
"human impacts on the environment are almost exclusively local or regional, not global:" to understand how wrong that statement is you have to look into climate research back a few decades. At the South Pole, the snow turning to ice has accummulated and captured as a record nuclear fallout, lead (Pb) from car gasoline, and pesticide use. And that when these changed, then nuclear testing was taken out of the atmosphere, then unleaded gas was introduced, and certain pesticides were changed the levels in whatever current level of snow recorded those changes. So until a reader recognizes that you will forever spin in a circular argument. --enm 16 Aug 2006 18:30 (UTC)
Yes it is a real concept but unfortunately it is not the concept that is being portrayed here. Though human impacts are certainly the central driver in many of the concepts talked about in global change the term itself is neutral - i.e. it simply means the study of the various components of change as listed at the beginning of the article, the best known of which (and possibly biggest component as well) is climate change. As someone added, the term is used widely in academia. Ken 20:57, 24 April 2007 (UTC)
This page could be made into a real gem
This page on global change could be made into an excellent umbrella page for its many sub-topics, but would require a concerted effort on the part of some actual experts.
