Paul Crookston of the Washington Free Beacon highlights an outlandish prediction from U.S. Rep. Alexandria Ocasio-Cortez.

Rep. Alexandria Ocasio-Cortez (D., N.Y.) said Wednesday that Miami has only a few years left on this planet.

At an NAACP forum, the democratic socialist touted the Green New Deal, her radical climate change plan many have criticized as unrealistic. Economists, investors, and energy industry experts have frequently noted the plan’s astronomical costs and the unreliability of renewable energy, but Ocasio-Cortez said her critics are the ones who are “not realistic.”

“When it comes to climate change, what is not realistic is not responding … with a solution on the scale of the crisis—because what’s not realistic is Miami not existing in a few years,” she said to applause.

“We need to be realistic about the problem,” she added.

Ocasio-Cortez proposed the Green New Deal as an “aspirational” plan and even resisted Republicans’ desire to vote on it, but fellow democratic socialist Sen. Bernie Sanders (I., Vt.) released a fleshed-out version of the plan as part of his presidential platform. Sanders’s plan would cost $16 trillion—more than 20 times as expensive, adjusted for inflation, as Franklin Roosevelt’s New Deal.
