Global impacts of extreme heat and climate change

Overview

Global reports from the United Nations Environment Programme and the Copernicus Climate Change Service indicate the planet is experiencing its warmest climate in modern human history. Experts warn that extreme heat is becoming a new climatic reality, characterized by increased frequency and duration, with an estimated nearly half a million people dying annually from related causes.

In the United States, extreme heat is intensifying financial and lifestyle disruptions. An AP-NORC poll shows that approximately 80% of adults report heat influencing electricity bills, up from 69% in 2024. In California, extreme heat days have increased by an average of 55% over two decades, with families spending an estimated $4 billion annually on cooling.

Recent data from First Onsite Property Restoration highlights growing public anxiety as a heat dome affects over 100 million people in the U.S. Approximately 70% of Americans identify extreme heat as their primary weather concern, followed by wildfire smoke and drought. While 72% of respondents worry about the impact of power outages, preparedness remains low; only 54% feel personally prepared for weather-related emergencies, and only 55% express confidence in local authorities’ ability to respond effectively.

In New York City, heatwaves have strained municipal infrastructure, with overcrowded public pools facing hygiene and safety challenges. Health officials warn that high density in aquatic facilities increases pathogen exposure risks, while the urban heat island effect heightens heatstroke risks for children and the elderly.

In Japan, persistent temperatures exceeding 30 degrees Celsius have raised heatstroke concerns and shifted consumer behavior. Meanwhile, in France, the summer of 2026 saw historic heatwaves and wildfires that destroyed over 96,000 hectares of forest, causing significant socio-economic disruptions and insurance market concerns.
