Scientists Link Climate Change to Heatwave Deaths
Imagine the Earth is getting a fever, and sometimes that fever causes heatwaves, like extra-hot days.
Scientists are now figuring out how much these heatwaves are hurting people.
They found that climate change, caused by things like pollution, is making these heatwaves worse.
They estimated that in a recent heatwave, many people died because of the heat, and that most of those deaths wouldn't have happened if the Earth wasn't getting warmer.
This study helps us understand how dangerous heatwaves can be and why we need to take care of the planet.
Scientists estimated 2,300 deaths across a dozen cities during a recent European heatwave.
The study linked heatwave deaths to climate change shortly after the event.
Researchers estimated 65% of the deaths were due to global warming.
The study was conducted by Imperial College London and the London School of Hygiene & Tropical Medicine.
Early estimates aim to raise awareness and prompt action to save lives.
