Co-founder of environmental organization Greenpeace Patrick Moore said Tuesday that the climate change crisis driving much of liberal politics today “is not only fake news. It’s fake science.”

Moore also wondered during his appearance on “Fox & Friends” why people would be worried about global warming: “A little bit of warming would not be a bad thing, for myself being Canadian.”

Moore bounced back into the climate change debate last week in an online feud with New York Democratic Rep. Alexandria Ocasio-Cortez after he blasted her Green New Deal for being not ambitious but ridiculous. (RELATED: Report: Rep. Ocasio-Cortez Has Violated Her Own Green New Deal)

“Well, it’s a silly plan; that’s why I suggested she was a pompous little twit, twit meaning silly in the British lexicon,” Moore told Fox, adding, “She really rubbed me the wrong way when she said she’s ‘the boss’ because she can make up a proposal that’s completely ridiculous, and nobody else did.”

Moore, who now sits as a director on the CO2 Coalition, a group of American and Canadian scientists who refute man-made climate change, says carbon dioxide is “the main building block of all life” and that it is good for the environment. “There is nothing to be afraid of.”

He doesn’t deny climate change. “Of course 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 … a completely natural phenomenon.”

Moore questioned why so many scientists who promote a climate change crisis receive “perpetual government grants,” insist “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.”

The former Greenpeace director says the organization has been “hijacked by the extreme left.” (RELATED: Greenpeace Admits Anti-Logging Campaign Is Based On ‘Subjective Opinion’)

Getting back to the Green New Deal, Moore insisted the plan is a recipe for catastrophe: “You cannot do agriculture for 8 billion people, produce the food for 8 billion people without fossil fuels.”
