A new analysis by Climate Central reveals that between December 2024 and February 2025, fossil fuel emissions intensified heat conditions, affecting billions globally.
The report attributes this rise in extreme temperatures to human activities such as burning coal, oil, and methane gas.
Using Climate Central’s Climate Shift Index (CSI), the study quantifies the influence of climate change on global temperatures over the past three months.
The findings indicate that one in five people worldwide experienced climate-induced temperature changes daily.
Nearly 394 million people were exposed to at least 30 days of extreme heat, classified as “risky” due to exceeding 90% of historical records from 1991 to 2020. Alarmingly, 74% of those affected reside in Africa.

The report states that in half of the 220 countries analysed, the average person endured climate-influenced heat for at least 30 days.
Urban areas are particularly vulnerable, with residents in 287 cities worldwide experiencing prolonged heat, exacerbated by population density and limited greenery.
The Nigerian Meteorological Agency has issued warnings about impending heat stress in 19 states, including parts of the South-East and coastal areas.
Regions expected to be severely impacted include North-Central and eastern states such as Kebbi, Niger, Kwara, Oyo, Kogi, Nasarawa, Benue, Enugu, and Anambra, among others.
Rising temperatures and humidity levels over the coming days could lead to fatigue, irritability, reduced concentration, and decreased productivity.
To enhance understanding, Climate Central has launched an interactive tool allowing journalists and researchers to explore climate trends and visualise regional impacts.
Policymakers and stakeholders are urged to use this resource to drive informed climate mitigation discussions.
