From global warming to heat waves

Don't like the heat? Blame global warming, says The Washington Post:

Heat waves like those that have scorched Europe and the United States in recent weeks are becoming more frequent because of global warming, say scientists who have studied decades of weather records and computer models of past, present and future climate.

While it is impossible to attribute any one weather event to climate change, several recent studies suggest that human-generated emissions of heat-trapping gases have produced both higher overall temperatures and greater weather variability, which raise the odds of longer, more intense heat waves.

The deniers may continue to deny it, at great risk to all of us, but this is yet more evidence that something is terribly wrong and that something must be done to confront perhaps our most pressing challenge.

Some -- like Al Gore, and perhaps even Tony Blair and Arnold Schwarzenegger -- are up to it. Others -- like James Inhofe and perhaps even George W. Bush -- clearly aren't.

Our side must prevail.
