UN Warns Earth ‘Firmly on Track Toward an Unlivable World’

Temperatures on Earth will shoot past a key danger point unless greenhouse gas emissions fall faster than countries have committed, the world’s top body of climate scientists said Monday, warning of the consequences of inaction but also noting hopeful signs of progress.

U.N. Secretary-General Antonio Guterres said the report by the Intergovernmental Panel on Climate Change revealed “a litany of broken climate promises” by governments and corporations, accusing them of stoking global warming by clinging to harmful fossil fuels.

“It is a file of shame, cataloguing the empty pledges that put us firmly on track toward an unlivable world,” he said.

Many Scientists Now Say Global Warming Could Stop Relatively Quickly After Emissions Go to Zero

Parts of the world economy may have been on pause during 2020, dampening greenhouse gas emissions for a while. But that didn’t slow the overall buildup of atmospheric carbon dioxide, which reached its highest level in millions of years.

If anything, research during the year showed global warming is accelerating. Symptoms of the fever include off-the-charts heat waves on land and in the oceans, and a hyperactive and destructive Atlantic hurricane season.
