Chelsea Clinton claims the world has only three years to save itself from global warming — which, conveniently, would be the same year her mother could again run for president.

Clinton took to Twitter to share an ominous story about the supposed effects of “climate change”:

These experts say we have 3 years to get climate change under control. And they’re the optimists-The Washington Post https://t.co/ZCFGpiswXa — Chelsea Clinton (@ChelseaClinton) July 3, 2017

“These experts say we have three years to get climate change under control. And they’re the optimists,” she wrote.

Clinton linked to a Washington Post article claiming:

A group of prominent scientists, policymakers, and corporate leaders released a statement Wednesday warning that if the world doesn’t set greenhouse gas emissions on a downward path by 2020, it could become impossible to contain climate change within safe limits.

The group, led by Christiana Figueres, who oversaw the United Nations negotiations that produced the Paris climate agreement, base their case on simple math. The world, they calculate, probably has a maximum of 600 billion remaining tons of carbon dioxide that can be emitted if we want a good chance of holding the rise in planetary temperatures within the Paris limit of 1.5 to 2 degrees Celsius (2.7 to 3.6 degrees Fahrenheit).

2020, of course, is a presidential election year. How convenient.
