A new study published in Nature Sustainability warns that if global temperatures rise by 2C, the number of people facing extreme heat will jump from 1.5 billion to nearly 3.8 billion by 2050. Researchers found that while tropical regions will be worst affected, northern countries are ill-prepared for the shift, with cooling demands expected to skyrocket. The findings emphasize the urgent need for adaptation measures in healthcare and infrastructure to handle unprecedented temperature extremes.
