Answer:
Climate change has caused a lot of Arctic snow to melt. Without enough snow to reflect solar radiation, the Arctic region is absorbing heat and getting warmer. Warmer polar winds and weak summer storms are proof of Arctic warming.
Cool, powerful summer storms provide welcome relief from heat waves in northern regions such as Europe. These storms are powered by the temperature difference between the hot land and the cold Arctic. But since the Arctic has gotten warmer, the temperature difference has reduced. The smaller temperature difference has resulted in weak, mild summer storms that are unable to snap heat waves. So, Arctic warming may have contributed to the massive heat wave of 2003.
