An “exceptional and dangerous” heatwave in the northwestern United States and western Canada is expected to lead to temperatures as high as 113°F (UN News) for five or so more days, a spokesperson for the World Meteorological Organization said.
The record-breaking temperatures are caused by a mountain of warm air called a heat dome (CBS) that scientists say is being
exacerbated by climate change (WaPo) and has become lodged in the Pacific Northwest, blocking other weather patterns. In the Vancouver area, police suspect heat is a factor behind
dozens of sudden deaths (CTV News Vancouver) that occurred within just a few days. U.S. President Joe Biden is holding a virtual meeting today with the governors of seven western states, cabinet officials, and private-sector representatives to bolster preparations for the upcoming wildfire season. Experts warn that it
could be more severe than last year’s (LA Times), which was the worst on record, due to the high temperatures and worsening drought conditions.
