The deadly heatwave that scorched large swaths of Mexico, Central America, and the southern US was made 35 times more likely due to human-induced global heating, according to research. Tens of millions suffered dangerous temperatures as a heat dome engulfed the region, causing widespread misery.
Heatwaves are four times more likely today than at the turn of the millennium, with extreme heat spells becoming deadlier. Lack of political action on fossil fuels will lead to common deadly heatwaves in a 2C world.
Extreme heat from such heatwaves increases rates of various diseases and threatens infrastructure. Without action, the impact on health, power supplies, and infrastructure will continue to worsen.
