To their credit, the other three on the panel (Sam Donaldson, Cokie Roberts, and George Stephanopolos) calmly refuted his tirade, albeit with a bemused look at the sad little man. All three agreed that while there may merit discussion on the severity of the problem (is it just the polar ice cap that's melting, or Greenland, as stated in An Inconvenient Truth?), there is no question that global warming/ climate change is a real problem.
I came across an interesting website that gives information on the efforts of companies to adress this issue. Because after all, even though you and I do everything we can to recycle, reuse, and reduce, the biggest impact is by far from manufacturing and other large corporations. You can see who takes climate change seriously (obviously George Will's name is not there!) at ClimateCounts.
For example, while it's true that nobody doesn't like Sara Lee, you might not like her so much after you read that she's basically doing nothing to decrease her rather large footprint. However, you will be pleased to know that Unilever, makers of Country Crock, Hellman's, Knorr, Lifebuoy, Lipton, Lux, Pond's, Slimfast, Vaseline, Wishbone, Dove, Ben & Jerry's, and I Can't Believe It's not Butter, among other things, has been tracking and reducing their impact on globla warming since 1995.
