Not necessarilly a hoax since it has been obsreved that the Martian ice caps are receding, but certainly NOT caused by Man. There is so much bad science there that one scarcely knows where to start.
Just like the ozone hole (pure BS)
Just like the "population bomb" (completely wrong)
Just like the oceans will be "dead in 10 years" (19 years ago now, thanks Ted "I look good but I'm dumber than a box of rocks" Danson)
Global warming is the crisis du jour, that's all.
Man's role in Global Warming on this Earth is misrepresented by the MSM to be sure.
The polar icecap problem on Mars, however, may be directly related to the Couch Jumper's movie.
