The once-in-a-decade wildflower "superbloom" in Death Valley National Park, North America's hottest, driest and lowest-elevation place, has ended due to an early heat wave in the American West. The National Park Service had declared 2026 a superbloom year, marking the first since 2016. The term is not scientific and there is no standard definition for what qualifies as one. The superblower year lasted longer than in 2016 due to cooler temperatures and more rain in February. Since March 17, Death Valley has recorded a daily high temperature at 100 degrees or above, and the all-time high March temperature is now 107 degrees, 3 degrees higher than the previous record set on March 26, 2022. Climate Central experts believe high temperatures in Death valley have been made five times more likely due to climate change and carbon emissions from fossil fuels.
