Bloomberg: It turns out that wild fluctuations in polar airflow that many experts blame on  climate change are bad for the industry most responsible for causing it. U.S. oil production has plunged by more than 2 million barrels a day as the coldest weather in 30 years wreaks havoc on key producing states that rarely have to deal with frigid Arctic blasts. Indeed, the unforgiving weather has pushed natural gas prices at one trading hub up 24,000% from just a week ago, halting fracking and even Amazon. Renewable sources also are in trouble, as are power companies. Don’t understand how a hotter planet can be responsible for bone-chilling cold? This is how the science works. —David E. Rovella
