Not to be outdone by the climate-fueled disasters broiling and incinerating the West, parts of the Mid-Atlantic have been deluged by torrential rain this week. As much as 10 inches of rain fell in less than 4 hours in southeastern Pennsylvania on Monday, prompting “widespread and life-threatening flash flooding,” according to the National Weather Service. Extreme precipitation is a clear signal of human-caused climate change — warmer air can hold more moisture and can thus dump more water when it rains. As of Tuesday morning, New York City saw rain on 9 of the 13 days so far in July for a total of 8.49 inches, and Boston’s month has been even wetter with 8.9 inches.
Meanwhile, more than 14,000 firefighters across the Western U.S. are battling to contain blazes in sweltering heat. Both extreme heat and wildfires are also clear signals of climate change. Numerous fires in the Pacific Northwest threaten Native American lands, including in what is now north-central Washington where residents of Nespelem on the Colville Indian Agency were ordered to leave because of “imminent and life-threatening” danger from five wildfires ignited by dozens of lightning strikes Monday night. “There is definitely extensive damage to the forest where we have our treaty rights,” Don Gentry, the chair of the Klamath Tribal Council in what is now Chiloquin, Oregon, about 25 miles west of the Bootleg Fire, told the AP.
