The fires come amid a sustained drought in parts of the western United States and as temperature records continued to tumble around the world. In Montreal, Canada, at least 12 people have died during a heat wave that’s seen the city post its highest temperature in recorded history—98 degrees. In Central Asia, Armenia’s capital posted a high of 108 degrees, while Tbilisi, Georgia, reached 105 degrees—breaking records for both cities, while southern Russia baked under record heat. And last week, a city in eastern Oman recorded the hottest low temperature ever observed—with sweltering overnight heat that bottomed out at 109 degrees. The scorching temperatures come as climate scientists say 2018 is on track to become one of the planet’s hottest years on record—possibly surpassing the past three years, which were the hottest ever recorded.
