The polar vortex made its way to Colorado, and it s been really cold. People are getting frostbite after weekend temps dipped below zero, and some utility companies had to urge customers to conserve power when the extreme cold created a regional shortage of energy.
The polar vortex is cold air that usually circulates around the North and South poles. The jet stream that keeps the cold air moving counter-clockwise and close to the poles can weaken when its winter in the Northern Hemisphere.
That sends cold Arctic air southward, which just led to the coldest air in decades across the United States. Dallas dipped to 5 degrees, the coldest temperature the city has seen since 1989. And Oklahoma City hit 6 degrees below zero, the city s coldest temperature since 1989, according to CNN.

Science lost a brilliant researcher and the planet lost a steadfast advocate with the death of Paul Crutzen on Jan. 28. Crutzen, an atmospheric scientist, was one of the first to link human activities to ozone deterioration, leading to the worldwide ban on ozone-depleting substances. He was awarded the 1995 Nobel Prize in Chemistry, with Mario Molina and F. Sherwood Rowland, for discovering the chemical processes that cause ozone depletion.
Crutzen pioneered many other significant scientific discoveries. He was the first to explore biomass burning’s impact on the atmosphere; he warned that nuclear war would lead to nuclear winter; he proved the Earth is in a new epoch influenced by humans, which he termed the Anthropocene; and he started the debate on potential geoengineering to abate the effects of greenhouse gases.
