1 in 5 People Feel Strong Climate Change Influence Globally

A new report from Climate Central reveals that one in five people worldwide—approximately 1.8 billion individuals (22% of the global population)—are experiencing significant temperature changes due to human-induced climate change, Anadolu Agency reported. This report covers the period from December 2024 to February 2025.

The findings indicate that extreme heat, primarily driven by the burning of coal, oil, and methane gas, has affected various regions. During this three-month span, nearly 394 million people faced 30 or more days of “risky heat,” with 74% of those affected located in Africa. “Risky heat” days are defined as those exceeding 90% of typical local temperatures from 1991 to 2020, heightening the risk of heat-related health issues.

The peak exposure occurred on February 28, 2025, when three billion people—37% of the global population—endured such extreme temperatures. The report underscores the urgent need to address the health risks associated with climate change.
