Climate change made killer heat wave in Mexico, Southwest US even warmer and 35 times more likely
Associated PressWASHINGTON — Human-caused climate change dialed up the thermostat and turbocharged the odds of this month’s killer heat that has been baking the Southwestern United States, Mexico and Central America, a new flash study found. And it was even worse at night, which is what made this heat wave so deadly, said Imperial College of London climate scientist Friederike Otto, who coordinates the attribution study team. Climate change made nighttime temperatures 2.9 degrees warmer and unusual evening heat 200 more times more likely, she said. They then used the scientifically accepted technique of comparing simulations of a fictional world without human-caused climate change to current reality to come up with how much global warming factored into the 2024 heat wave.
