Only someone completely unable to think critically would believe for a moment that humans haven’t made an impact on the Earth (just look at these before and after pictures to illustrate). Certainly fairly liberal organizations have compiled information about global warming…but conservative pro business publications like Forbes magazine insert at least some meaningful data within their pages from time to time (or online in this case).

Forbes had this article today about Past Climate Change Supports Current Global Warming:

Some of the strongest evidence yet of a direct link between tropical warmth and higher levels of greenhouse gases is found in past climate records, U.S. researchers say.

The current steady increase in tropical temperatures caused by global warming could have a major impact on global climate and result in more destructive storms like Hurricane Katrina, according to a team at the University of California, Santa Barbara.

The study appears this week in Science Express, the online publication of the journal Science. In addition, Google Scholar has this list of studies on global warming for your leisure reading pleasure.
