Gore vs. Hansen: Enviros take sides in debate over House climate bill:
The Waxman-Markey climate and energy bill,
now moving through the House, is polarizing the environmental
community. Longtime climate crusader Al Gore says we should do all we
can to get the legislation passed; top climate scientist James Hansen
says we should demand a different, better bill. Activists and
environmental groups are picking sides or staking out positions in the
middle.
