Newly announced 2020 hopeful Beto O’Rourke’s platform already has a gaping hole in it, according to a co-founder of the environmental group Greenpeace.

Patrick Moore was asked Thursday by the Fox Business Network to weigh in on the former Texas congressman’s claim that mankind is causing climate change that will lead to massive population disruptions and ultimately “extinction.”

“The real irony I see is Beto on the one hand is saying there’s going to be millions of climate refugees at the southern border while at the same time he’s calling for the wall to be taken down,” Moore said. “What kind of a position is that?”

O’Rourke has said a border wall is a “racist response to a problem we don’t have” and told MSNBC last month he not only opposed Trump’s construction plans, he would rip out existing walls on the southern border.

Moore was asked to comment on O’Rourke’s contention, also claimed by Rep. Alexandria Ocasio-Cortez, D-N.Y., that the world is going to end in 12 years unless something is done about the climate.

“I don’t know how these people get this idea that the world is going to come to an end,” he said. “The environment has been getting cleaner for 50 years. The air is cleaner, the water is cleaner now in our part of the world.”

He said it’s true that other parts of the world need to do more, “but they’re coming up out of poverty … and they’re demanding more environmental standards.”

“I simply don’t understand how anybody could think that their children won’t be able to breath the air in 10 years,” Moore said. “What is he thinking?”

WND reported earlier this week that after a Twitter debate with Democratic Rep. Alexandria Ocasio-Cortez, Moore summarized his fierce opposition to the New York congresswoman’s “Green New Deal” in an interview, saying it would “basically be the end of civilization.”

Without fuel, Moore asked, how does the food get to the center of New York City, where Ocasio-Cortez is from?

“You don’t,” he said. “Then the people there will begin to starve, and that will spread out as a rot from the center of the metropolises across the country, and half the population will die in a very short period of time.”

Moore also argued that in such a scenario, assuming the Paris accord were implemented worldwide, “there wouldn’t be a tree left on this planet, because that would be all there was for fuel for heating and cooking.”

“So just that one point – never mind the insanity of aircraft and fossil-fuel-using vehicles,” he said.

Moore, the director of the CO2 Coalition, a group of American and Canadian scientists skeptical of man-made climate change, acknowledged in an interview Tuesday morning with “Fox & Friends” that “climate change is real.”

“It’s been happening since the beginning of time, but it’s not dangerous and it’s not created by people,” he said, calling it a “completely natural phenomenon.”

He noted climate-change scientists who receive “perpetual government grants” contend “the science is settled and say people like myself should just shut up.”

“On the other hand, they keep studying it forever as if there’s something new to find out.”
