Summer Heat Waves May be Linked to Arctic Warming

Before the summer of 2010, Moscow had never recorded a triple-digit temperature, with records going back to 1879. But during a weeks-long heat wave that June and July, the city’s temperatures soared well above normal, setting an all-time record high of 102°F on July 30. A new study suggests that Arctic warming could have helped trigger that epic heat wave.
