Unusual weather why?

New research presented at the American Association for Scientific Advancement (AAAS) in Chicago identified climate change, as shown by warming in the Arctic, which is the main cause of stormy weather conditions. Nordic and cold stretched in North America recently.

>>>The first snowstorm in the US pulled the temperature down to a record low

According to the BBC on February 15, temperatures in the Arctic have increased 2-3 times faster than the rest of the world, leading to an increase in the winding of jet streams - a high-velocity air flow present on the stratosphere of the atmosphere and determines the weather below the ground.

Jet stream is greatly influenced by the temperature difference between the North Pole and the average latitude. It makes the weather colder south and warmer to the north like Alaska and parts of Scandinavia have warm weather conditions this winter. In contrast, with the United States, Britain and Australia the severe weather situation lasted by the increase in the winding of the jet stream.

Meanwhile, on thinkprogress.org, Professor Jennifer Francis from Rutgers University, New Jersey (USA) said that with global warming, any storm formed during this time has more energy thanks to heat. and moisture to become stronger.

Meanwhile, the Los Angeles Times led a new survey of Wall Street traders that showed continuous and persistent snowstorms in the winter that caused the US economy to lose $ 50 billion in productivity and 76,000 jobs. Snow, ice, and coldness reduce the economic growth by about 0.3%.
