Cisco CEO takes jab at climate change deniers

Smilin' John Chambers is one of the most polite speakers you'll ever meet, but he says you're way off the boat if you deny global warming.

John Chambers, CEO of Cisco Systems, is one of the least controversial CEOs in the tech world. Unlike Craig Barrett (former Intel CEO) or Cypress Semiconductor's T.J. Rodgers, he doesn't generally take potshots at Washington politicians. Cisco provides its opinion on issues like immigration, open access, and foreign competition, but the company rarely insists on playing the leading role in these controversies.

Chambers even wisely plays both sides in campaign contributions. He's donating to John McCain's presidential campaign, but also gave to Senator Harry Reid and the Democratic National Party, among others, according to this Web site. Most of his donations tilt Republican, but he definitely placates both parties.

The Cisco CEO, however, does have strong feelings when it comes to climate change. It is undeniable that atmospheric carbon dioxide is rising and that the earth's temperature is rising, he said at the Connected Urban Development conference taking place in San Francisco this week.

"It (climate change) is not a question of if. It is," he said. "There is no doubt in hardly any of the well-educated minds that if we don't act quickly, we are going to have a tremendous problem on our hands."

Chambers also said he now looks more favorably on government participation in projects.

"This is probably not something I would have said 10 years ago, but it is hugely important to have a supportive government."
