The Polar Vortex Is Climate Disruption in Action

The sub-zero temperatures across the country don’t contradict global warming. They’re actually caused by it.

A man walks along an ice-covered breakwall along Lake Michigan while temperatures were hovering around -20 degrees and wind chills neared -50 degrees on January 31, 2019, in Chicago, Illinois.

Part of the Series

Truthout’s December fundraiser is our most important of the year and will determine the scale of work we will be able to do in 2026. Please support us with a tax-deductible donation today.

At least 20 people have died and vast swaths of the US Midwest and Northeast have come to a standstill because of a frigid blast of sub-zero temperatures. Another Arctic vortex has struck.

A polar vortex is a large expanse of swirling, cold air that is usually located in the polar regions. However, during winter, and now more frequently due to human-caused climate disruption, the vortex expands and moves southward, bringing the Arctic temperatures with it.

Studies have shown that a warming Arctic is shifting the jet stream, and playing a critical role in the changes that are causing the polar vortex to become more common in the US.

In addition to deaths, the record low temperatures have resulted in many frostbite patients flocking to hospitals, the grounding of more than 1,600 flights in the Chicago area alone, and the US Postal Service ceasing mail delivery at times in certain areas.

Parts of the Midwest saw temperatures plummet to minus 37 degrees Fahrenheit, while Boston saw minus 5 degrees Fahrenheit. Areas of Northern Illinois saw temperatures of minus 57 with the wind chill.

There were times when temperatures in areas of the Midwest were lower than they were in Antarctica.

Strained Infrastructure

As human-caused climate disruption continues to worsen, extreme weather events such as this will continue to place, increasing demands on infrastructure.

For example, one utility company realized it was in danger of being unable to keep pace with the demand for natural gas, given the spike in need for heating in Michigan. After the company made an emergency appeal for everyone to conserve gas during the deep freeze, General Motors suspended operations at 11 of its plants in that state.

Homeless shelters in Lansing, Michigan, were overcrowded, and churches had to step in to assist, as did various city departments.

The Depths of Denial

On January 28, President Trump tweeted:

In response, the US National Oceanic and Atmospheric Administration (NOAA) tweeted:

NOAA’s tweet included a link to an article that suggested severe snowstorms may well become more likely as the planet continues to warm.

Our most important fundraising appeal of the year

December is the most critical time of year for Truthout, because our nonprofit news is funded almost entirely by individual donations from readers like you. So before you navigate away, we ask that you take just a second to support Truthout with a tax-deductible donation.

This year is a little different. We are up against a far-reaching, wide-scale attack on press freedom coming from the Trump administration. 2025 was a year of frightening censorship, news industry corporate consolidation, and worsening financial conditions for progressive nonprofits across the board.

We can only resist Trump’s agenda by cultivating a strong base of support. The right-wing mediasphere is funded comfortably by billionaire owners and venture capitalist philanthropists. At Truthout, we have you.

We’ve set an ambitious target for our year-end campaign — a goal of $250,000 to keep up our fight against authoritarianism in 2026. Please take a meaningful action in this fight: make a one-time or monthly donation to Truthout before December 31. If you have the means, please dig deep.
