West Coast Heat Wave Breaks Records and Continues to Threaten.

Millions of people on the West Coast are facing a continuation of intense early-season heat for multiple days, with record-breaking temperatures in Washington, Oregon, and California. The majority of households in the region are not equipped with central air conditioning, raising the risk of heat-related illness. More extreme heat is an indicator of human-caused climate change, according to scientists. The increase in heat days has been observed in every region in the U.S., with the South and Southeast being the riskiest heat spots.
