Study: Climate Change Caused Extra Month of Extreme Heat
Imagine half the world feeling a whole extra month of summer heat.
That's what happened from May 2024 to May 2025.
Scientists say it is because of climate change.
They looked at how much hotter it was than it should have been without climate change and found that it was a lot.
It made people sick and hospitals strained.
They say that we have to stop burning fossil fuels, and also get ready for more heat by making plans and building better buildings.
Approximately 4 billion people experienced an extra month of extreme heat between May 2024 and May 2025.
The study analyzed extreme heat days, comparing them to a world without human-caused warming.
Climate change was found to be a factor in 67 extreme heat events.
Aruba was the worst-affected location, experiencing 45 more extreme heat days than expected.
Scientists emphasize the need for early warning systems and reducing fossil fuel use.
