Deseret News | Climate change real, Y. expert says

PROVO — Until now, humans have had room for error in regard to emitting carbon dioxide into the atmosphere.

But now, Brigham Young University biology professor and climate change expert Richard Gill told a group of students and professors Thursday at BYU, the earth has essentially reached its potential to absorb and store carbon dioxide. The result, he said, is that climate change is more of a reality now than ever before.

Gill used examples from findings published in 2007 by the International Panel on Climate Change and studies he took part in to show the reasons behind climate change, which he said is often misrepresented in politics. He said the validity of climate change is nearly universally accepted by the scientific community and is not controversial.

BYU chemistry professor David Belnap said he invited Gill to speak after he realized how much he didn't know about climate change when the topic came up in his classes. He said those discussions angered some of his students, who thought he was crossing the political neutrality line by bringing up a hoax.

"A lot of them are worried that their freedom is threatened," he said. "I think our freedom is more threatened if we allow it to go on and don't do something about it."
