Hysteria: The United Nations climate chief says that the world has no choice but to "decarbonize." That's her opinion. But it shouldn't be mistaken for unimpeachable advice.

Christiana Figueres, executive secretary of the U.N.'s Framework Convention on Climate Change,said, "A decarbonized world is now irreversible, irrefutable," and "We are going to do it, because frankly we don't have any other option."

An astrophysicist who studies the sun will present a lecture Monday that outlines how solar activity affects our climate. 

Nir Shaviv from the Hebrew University of Jerusalem is a scientist, and he believes that the sun is the primary driver of the slight warming across the 20th century that some have observed.

"What is the evidence supporting the claim that most of the warming is anthropogenic?" Shaviv asks in the ScienceBits blog.

"It turns out that there is no direct evidence supporting this link! There is no fingerprint which proves that the warming is caused primarily by CO2 or other anthropogenic greenhouse gases."

Shaviv insists, "The culprit responsible for the warming" is not a mystery but "is as clear as the light of day."

"It is the sun," he says.
