President Barack Obama fired back at Republican frontrunner Donald Trump shortly after the GOP presidential candidate blasted Obama's claim that global warming was one of the greatest threats to the United States.

Obama smirked when "CBS This Morning" co-host Norah O’Donnell reminded Obama Trump was the Republican frontrunner.

And Obama laughed when O’Donnell told him about Trump's declaration that Obama had made "one of the dumbest statements I've ever heard in politics."

Obama replied, "Well, you know, Mr. Trump should run back a tape recorder on some of the stuff he's said," and he and O'Donnell chortled.

Obama also took an implicit swipe at Trump by saying, "You can't build a border wall when it comes to carbon emissions or global temperatures or the oceans."

In his 2015 State of the Union speech, President Obama stated, "Today, there is no greater threat to our planet than climate change."

Following the terrorist attacks in Paris, Obama suggested the climate change meeting to be held in the city would somehow serve as a rebuke to the Islamic State.

Earlier this week, the President Obama also stated climate change was "akin to the problem of terrorism and ISIL."

Such comments led conservative radio host Glenn Beck to strongly criticize, exclaiming, "Mr. President, I say this with as much respect as you deserve, screw global warming! What the hell is wrong with you?"

"If you actually believe that global warming is the biggest problem we face with terror all around the world, an $18 trillion dollar debt – nine of which is yours – no real allies left that trust us, riots in the streets, riots in our university campuses, race relations worse than I've seen since the 1960s, and a distrust of our fellow Americans unlike anything I have ever seen, you, sir, are either delusional or you're the dumbest son of a b**** on the planet. Which is it?"

During his interview on CBS, Obama claimed: "Ninety-nine-point-five percent of scientists in the world say this is a really urgent problem. The only people who are still disputing it are either some Republicans in Congress or folks on the campaign trail."

Yet in light of recent scandals over the validity of climate data, the president's confidence in the science could be misplaced. As revealed in Sen. Jim Inhofe's "The Greatest Hoax: How The Global Warming Conspiracy Threatens Your Future," the "Climategate" scandal showed the United Nations' Intergovernmental Panel on Climate Change (IPCC) may have been manipulating data and was putting a political agenda above scientific objectivity.

Recent data even revealed the arctic ice cap is actually growing, not shrinking, defying the predictions of climate change activists like former Vice President Al Gore. Expert observations in early 2015 also showed official temperature records cited to prove the existence of global warming had been systematically adjusted to falsely present the Earth as having "warmed" far more than the data showed.

This led a writer at the United Kingdom's Telegraph to call the manipulation of climate data "one of the greatest scientific scandals of all time."

Not surprisingly, the public seems to be tuning out warnings of apocalyptic doom. A recent poll from Fox showed only three percent of Americans thought "climate change" was the most important issue facing the country. Another poll taken in mid-October showed fewer than one in four Americans were extremely or very worried about climate change and only 36 percent saw climate change as a moral issue.

Nonetheless, don’t expect the climate change movement to go away anytime soon. Brian Sussman, a talk show host, former meteorologist and author of "Climategate" and "Eco-Tyranny" predicts environmentalists will simply double down on their claims. After all, he says, "climate change" has become a big business.

"I don't see the climate change industry backing down because there is too much money to be made and too much power to be acquired," Sussman told WND. "Again, the goal for some is to make loads of money, and for others to use 'sustainable development' as the key to pushing for global socialism and communism."

Sussman accused the mainstream media of "carrying the torch for the climate agenda" and alleged the recent summit in Paris was dominated by this cynical agenda.

"The agenda in Paris has two parts," said Sussman. "One, to allow those heavily invested in renewables to make more money, which they give to politicians for favor, low interest loans, government loans etc. Two, to push the socialist, redistribution, communist agenda."

However, Sussman thinks there is something motivating the "climate change" movement that actually goes beyond money or a lust for power.

"This is like a cult!" he exclaimed.

Sussman does not think there is any conceivable kind of evidence that would force climate change industry to back down.

"They don't need evidence," he said. "If it warms, cools, storms, it doesn't matter, it's all called climate change. The scientific method has been thrown out the window."

Sussman warns Americans need to take action against this agenda before it's too late.

"We need a president and Congress that have the guts to seriously do something to stop our participation in this madness."
