World not ready for rise in extreme heat, scientists sayPARIS, France, Jan 26, 2026 (BSS/AFP) - Nearly 3.8 billion people could face extreme heat by 2050 and while tropical countries will bear the brunt cooler regions will also need to adapt, scientists said Monday. They found "that the population experiencing extreme heat conditions is projected to nearly double" by 2050 if global average temperatures rise 2C above preindustrial times. "The key take away from this is that the need for adaptation to extreme heat is more urgent than previously known," said Lizana, an environmental scientist. Prolonged exposure to extreme heat can overwhelm the body's natural cooling systems, causing symptoms ranging from dizziness and headaches to organ failure and death. - 'Dangerously underprepared' -The study, published in the journal Nature Sustainability, projected that 3.79 billion people worldwide could be exposed to extreme heat by mid century.
