The Polar Vortex And Climate Change Explained

Written last year during a breakdown of the polar vortex, this article provides an in-depth look at how climate change produced by global warming causes a disruption of the Polar Vortex and extremely cold temperatures. The article does a good job explaining how decreased sea ice levels weaken and shift the stratospheric polar vortex, a low-pressure weather system that helps produce regional climate patterns, and shows how a weakened polar vortex then causes colder temperatures in southern areas across the USA, Europe, and Asia.

This article and others have pointed to the mounting level of research indicating that warm arctic weather is increasing the frequency with which extreme winter weather occurs in the United States. This study from 2017 has also demonstrated how warming arctic temperatures are causing cold temperatures across North America and other southern mid-level latitudes. The Journal Nature also explains how warmer Arctic weather is weakening vegetation and causes low crop productivity.
