Global warming is causing colder winters


Climate change is linked to global warming, but rising greenhouse gases lead to colder winters in the United States and Europe, where scientists from the Massachusetts Institute of Technology revealed that abnormal warming at the poles results in excess energy that weakens the polar vortex and splits it into vortices. Smaller travels outside the usual Arctic range.

The split in the polar vortex could lead to sudden and delayed effects, many of which include lower temperatures and harsh winter weather in the United States and northern and western Europe.

Scientists believe that the splitting vortex caused the February cold snap that killed up to 700 people in Texas, and left more than 3.5 million dead. million without electricity.

Despite rapid warming that is a key signature of global climate change, especially in the Arctic, the United States and other regions of the Northern Hemisphere have experienced an increasingly visible and frequent number of episodes of extreme cold winter weather over the past four decades.

The change in the Arctic is likely to be an important cause of a chain of processes involving what they call a perturbation of the polar vortex, which eventually leads to periods of extreme cold in the northern mid-latitudes, a range that includes 36 countries in North America, Europe, East Asia and Central Asia.

There has long been a distinct contrast between warmer temperatures globally and the apparent increase in maximum temperatures in the United States and northern Eurasia, and this study helps resolve that discrepancy.
