Russian climatologist Aleksey Korkorin believes global warming contributed to the violent weather conditions that downed the French Airbus on 1st June. The article also brings up the disturbing thought that the pilots could have turned back from the storm but may not have done so because of the cost involved (RT):
Meanwhile, Russian General Pyotr Deinekin, a former commander of the Russian Air Force, postulated the tempting theory that although the flight crew was equipped with “onboard devices enabling it to see a dangerous situation beforehand” the pilots would have needed “great courage” to turn their planes back to base due to financial considerations. “Since this (turning a plane around) involves great financial losses for the airline, the captain apparently decided to continue the flight, which ended up tragically,” Deinekin told Interfax.
