"If we halved the carbon dioxide content [in the atmosphere], we would have no life on Earth."

"If we halved the carbon dioxide content [in the atmosphere], we would have no life on Earth."

Geologist Prof. Ian Plimer: "For about 80% of time [the atmosphere] was carbon dioxide rich... We had ice ages at the equator, and we had ice at sea level... yet the atmospheric carbon dioxide content was 20%."

"And we're told that at 0.04%, if we increase it by a little bit, we're going to have runaway global warming. We didn't have it in the past, so why should we have it in the present?"

"So we geologists see that this is a load of nonsense."

"When we look over time, we see that carbon dioxide has decreased... We are at a dangerously low level. If we halved the carbon dioxide content, we would have no life on Earth."
