Small tropical islands are projected to experience significantly increased humid heat stress by the end of the century due to climate change. This phenomenon, driven by rising temperatures and humidity, makes it harder for the human body to regulate its temperature through sweating. A recent study published in Geophysical Research Letters highlights that islands near the equator will face the most severe impacts, with dangerous humid heat events potentially occurring annually by 2100. Using data from 15 global climate models and observations from 17 tropical islands, researchers found that heat index values could reach up to 63°C (145°F), surpassing 'danger' thresholds set by NOAA. The study emphasizes that current climate models often overlook the specific challenges faced by small islands, leading to underestimations of their vulnerability.
