(CNN) — Democratic Sen. Mark Kelly on Sunday leaned into his experience as an astronaut to call for climate crisis action amid a blistering heatwave across the United States, including his home state of Arizona. As the climate crisis ratchets temperatures higher and higher, scientists have warned there’s a growing likelihood that 2023 could be the Earth’s hottest year on record. These climate crisis warnings have been especially potent in recent days as more than 85 million people remain under heat alerts while the weekslong heat wave continues and intensifies in the Southwest. We are suffering a heat wave here in Arizona. The world is “walking into an uncharted territory,” Carlo Buontempo, director of the European Union’s Copernicus Climate Change Service, told CNN earlier this month.
