Most of the US will enjoy milder temperatures on Thursday, but the warmup will be brief as a polar vortex will send temperatures tumbling below freezing for most of the nation starting this ...

As the Artic is warming much faster than other parts of the planet, the temperature difference that helps maintain the polar vortex's stability is reduced, resulting in a weaker jet stream ...

This winter, it seems as if temperatures have been fluctuating more significantly. Over the past year, it seems as if severe weather events have been occurring more frequently as well. Answers as ...
