Both leading Democrat and Republican candidates vie to show they can tackle global warming.
Now that Sen. John McCain is the presumptive GOP nominee, all three of the leading presidential candidates seem likely to tackle climate change in a way that clearly will distinguish the next president from the George W. Bush administration.
Senator McCain was one of the first on Capitol Hill, and one of the few of his party, to acknowledge the reality of global warming and the need to act quickly. His position on the issue is one reason why hard-core conservatives have been suspicious of McCain.
On the eve of this week's "Potomac primaries" in Maryland, Virginia, and the District of Columbia, Senator Obama aligned himself with former vice president Al Gore's push to make the US take the lead on reducing greenhouse gases. The Washington Post reports:
"[Obama] said he would start developing the U.S. position on a pact to replace the Kyoto Protocol before the general election in Novemberâ€¦. 'I think we need to start reaching out to other countries ahead of time, not because I'm presumptuous, but because there's such a sense of urgency about this.' "
