Press secretary Sarah Huckabee Sanders said the White House’s strategy to deal with Rep. Alexandria Ocasio-Cortez is to ignore what she says, especially her doomsday prediction about climate change destroying the world in just 12 years.

“I don’t think we’re going to listen to her on much of anything — particularly not on matters we’re gonna leave in the hands of a much, much higher authority — and certainly, not listen to the freshman congresswoman on when the world may end,” Sanders said Tuesday on Fox News’ “Hannity.”

The 29-year-old Democrat said during a Martin Luther King Jr. commemoration that climate change is this generation’s “World War II.”

“Millennials and people, you know, Gen Z and all these folks that will come after us are looking up and we’re like: ‘The world is gonna end in 12 years if we don’t address climate change and your biggest issue is, how are we gonna pay for it?'” Ocasio-Cortez said Monday.

She was apparently referring to a report released last October by the United Nations Intergovernmental Panel on Climate Change that warned that there are only a dozen years left to keep global warming at a maximum 1.5C.

A rise beyond that will substantially increase the risk of droughts, floods and extreme heat.

President Trump, who withdrew the US in 2017 from the Paris Climate Agreement, mocked climate change in a tweet Sunday as bitter-cold temperatures were recorded across much of the country.

“Be careful and try staying in your house. Large parts of the Country are suffering from tremendous amounts of snow and near record setting cold,” he said in the posting. “Amazing how big this system is. Wouldn’t be bad to have a little of that good old fashioned Global Warming right now!”
