Gore gets a warm welcome on Capitol Hill, and a few heated exchanges

Al Gore got a superstar reception in Congress yesterday when he made the case for sweeping federal action to fight global warming. Politicians from both sides of the aisle welcomed him back to his old stomping grounds and listened intently as he put forth 10 bold proposals for staving off the climate crisis, from an immediate freeze on CO2 levels to a carbon tax to a ban on incandescent light bulbs. Of course, there were a few grumblers in the hall (one of whom mentioned Grist, as it happens) — but would it be any fun without them? Muckraker reports from the scene.
