Extreme heat is becoming a more frequent and severe threat, but the world's response is still too slow and too shallow. According to Grist, scientists argue that the current toolkit for coping with heatwaves—chiefly early warning systems and cooling centers—does not go far enough to protect people.
The problem is that these measures are largely reactive. They help people survive a single heat event, but they do little to address the underlying conditions that make heat dangerous, such as poorly insulated housing, lack of shade, and urban surfaces that absorb and radiate heat.
Experts quoted in the article emphasize the need for more durable solutions. That means rethinking city design, upgrading buildings, and ensuring vulnerable populations have access to safe, cool environments long before a heatwave hits. Without such systemic changes, heat adaptation will continue to lag behind the rising threat.
