"I'm here to announce, and I feel very good being able to do it with 20 kids and grandkids, I'm happy to tell them all right now, the world's not coming to an end," he added.

Inhofe was responding to a lengthy discussion about climate science by Sen. Bernie SandersBernie SandersSanders keeping door open on 2020 Parliamentarian deals setback to GOP repeal bill OPINION | Hey Dems, Russia won't define 2018, so why not fix your party's problems instead? MORE (I-Vt.), who said Inhofe is "dead and dangerously wrong" to dismiss climate warnings.

Inhofe spoke immediately after, and recounted the several years in the 1970s when scientists were afraid of another ice age on Earth. He chalked that up to a general state of alarm that scientists seem to want to maintain when it comes to climate.

"Now, we're all going to die, keep that in mind, whether it's global warming or another ice age, we're all going to die," he said.

He also cited data showing that the production of man-made gasses does not always coincide with warming.

"The assertion is always made that we're having catastrophic global warming because of man-made gasses," he said. "And yet the greatest surge in the history… in CO2 came right after World War II, starting in 1945, and that precipitated not a warming period, but a cooling period."

Inhofe also cited several scientists who are skeptics, and said that despite attempts to convince people, scientists who continue to advocate for the theory that mankind is altering the atmosphere are losing the battle. He cited polls in 2010 showing that nearly three-quarters of those polled don't see global warming as a serious issue.

"I would just suggest that they're not winning that battle," he said.

Inhofe stressed several times that he and Sanders are good friends, despite their differences over climate science, and said Sanders is one of his favorite liberals because he "believes in his heart everything he says."

"People don't understand, they really don't understand what it's all about," Inhofe said. "The House wasn't that way when I was in the House. But in the Senate, you can love someone and disagree with them philosophically and come out and talk about it."
