In a study published in the journal Science this week, scientists argue that polar ice melt in the Arctic is responsible for a weakened Jet Stream. Data shows that, as a result, storm and wind patterns traditionally powered by the Jet Stream have lost energy in recent years, leading to greater instances of temperature extremes and prolonged droughts.

"Unabated climate change will probably further weaken summer circulation patterns which could thus aggravate the risk of heat waves," study co-author Jascha Lehmann, a climatologist at Potsdam University, told Bloomberg in an e-mailed statement. "The warm temperature extremes we've experienced in re...
