Summer temperatures in Reno have risen 10.9 degrees Fahrenheit, on average, since 1970, making it the fastest warming city in the nation during the hottest months, according to an analysis by the nonprofit research group Climate Central. For two consecutive summers, smoke from blazes burning in California has choked the region, sending residents to the emergency room, closing schools and threatening the tourism industry. It is among the sharpest examples of how climate change is fundamentally altering the summer months — turning what for many Americans is a time of joy into stretches of extreme heat, dangerously polluted air, anxiety, and lost traditions.

Though the summer season of 2022 is young, parts of the nation already have experienced punishingly high temperatures, extreme drought, wildfires, severe storms, flooding or some combination. Projections from federal agencies suggest more abnormally hot weather, an expansion of drought and well above average wildfire and hurricane activity in the months ahead.

Scientists say the recent spate of severe summers is a clear change from previous generations. The average summer temperature in the past five years has been 1.7 degrees (0.94 Celsius) warmer than it was from 1971 through 2000, according to a Washington Post analysis of data from the National Oceanic and Atmospheric Administration. But some parts of the country have been much harder hit, with the West showing a 2.7 degrees (1.5 Celsius) increase.
