Physicist – CO2 does not cause climate change, it RESPONDS to it – Video
More CO2 would actually help the planet , says Professor William Happer of Princeton University. CO2 can actually be beneficial to an ecosystem rather than a burden. Interviewed on TV at ‘Squawkbox.‘ Asserts levels of atmospheric carbon dioxide TEN TIMES higher than today is positively good thing. No risk to health, environment.
Highlights of the video:
Is there a correlation between CO2 and temperature?
Happer: “Yes. (However), temperature always changes first, and CO2 follows.”
Host: (2:39 into the video): “Has there been any global increase in temperature since 1998?”
Happer’s clear and simple answer: “No.”
Happer (3:48 in): A thousand parts per million (ppm) of CO2 would actually help the planet.
How? Because agricultural productivity would go up.
Several thousand ppm in greenhouses
Happer: “if you look around the world, many greenhouse operators put several thousand parts per million into their greenhouses.
Host: “Would there be any negative effects on humans from breathing a thousand parts per million?
Happer: “No, absolutely not.” Our primate ancestors were here roughly 70 to 80 million years ago when CO2 levels were 3,000 parts per million. That’s when we evolved. “So it was ten times what it is now.”
Happer: “We also let our sailors in submarines live in atmospheres that are several thousand parts per million.”
Glacier Bay glaciers disappeared long before any increase in CO2
Happer (6:20 in): “The glaciers in Alaska’s Glacier Bay are all gone. They disappeared in the 1800s.”
Happer: “In fact, that was one of the most famous trips of John Muir. Muir, the founder of the Sierra Club, was visiting Glacier Bay in 1879, and he pointed out all the glaciers were gone. That was long before there was any increase of CO2.”
