Rep. Alexandria Ocasio-Cortez ramped up the rhetoric in her push for a Green New Deal, describing it as a “life and death” issue.

The star freshman Democrat fired off a series of tweets Tuesday night about her controversial proposal.

“Don’t mess with our future. When it comes to climate, it’s all our lives at stake. The younger you are, the more consequences you’ll see. It’s life and death for us. And we will fight like it,” she tweeted.

The New York Democrat also attacked the GOP for allegedly ‘doing nothing to stop’ climate change, before turning up the heat on Republicans she accused of trying to sow doubt on the issue.

COTTON SAYS MEDIA WAS ' STALIN-LIKE ' IN OCASIO-CORTEZ GREEN DEAL COVER UP

“They knew early… Do you really think these increasingly regular & horrific wildfires & droughts are a coincidence? That growing regularity of '100-year floods' is an accident?

“We are losing our homes & loved ones *now.* And GOP doesn’t even care enough to try.”

The rising democratic socialist star’s remarks came after Arkansas Republican Sen. Tom Cotton blasted the Green New Deal plan and said the media were “complicit” in burying the most radical parts of the deal.

Cotton, a staunch Republican, appeared on "The Hugh Hewitt Show" on Tuesday and discussed the Green New Deal that aims to implement sweeping changes across the nation.

But he claimed the media became complicit in hiding a now-infamous FAQ document circulated by the Ocasio-Cortez office, which included lines such as promising a job to “all people of the United States” – including those “unwilling to work” – and making air travel obsolete.

“I understand the Democrats that proposed this immediately tried to retract that white paper that went along with their resolution,” Cotton added. “And too many people in the media have been complicit in the Stalin-like or 1984 technique of disappearing it, sending it down the memory hole.”

Multiple Democratic 2020 candidates such as Sens. Elizabeth Warren, Cory Booker, Kamala Harris, and Kirsten Gillibrand have endorsed the deal .

“I’m proud to co-sponsor @AOC and @EdMarkey's Green New Deal. We must aggressively tackle climate change which poses an existential threat to our nation,” Harris wrote when announcing her support of the plan, adding in that “The Green New Deal is a bold plan to shift our country to 100% clean and renewable energy.”
