HBO has been airing a documentary titled "Too Hot Not to Handle."  It's scheduled for various times through May 30.  You can check the schedule at http://www.hbo.com/docs/programs/toohot/?ntrack_para1=leftnav_category1.  I watched the documentary and I was impressed that it included interviews and video with voiceovers from scientists who are concerned about global warming and believe it's real.

Too Hot Not to Handle

Heat waves. Melting glaciers. Rising sea levels. Catastrophic storms. Migrating viruses. Population displacement. Over the past 100 years, the mass consumption of fossil fuels, especially in America, has contributed to a dangerous warming of the earth that has adversely impacted the way we live. The cautionary documentary TOO HOT NOT TO HANDLE offers a guide to the effects of global warming in the United States.
