Global Heatwaves Surge: Climate Change Fuels Extreme Weather
6 Nov
Summary
- Rising temperatures make heatwaves more likely and intense globally.
- Increased atmospheric moisture leads to heavier rainfall events worldwide.
- Climate change exacerbates drought conditions and wildfire risks.
Human activities, particularly the burning of fossil fuels, are significantly increasing the frequency and intensity of extreme weather events worldwide. Even a slight rise in average global temperatures leads to more severe heatwaves, as experienced during the UK's record-breaking summer in 2026. This warming trend contributes to heat domes and intensifies multiple heatwaves across continents.
Atmospheric moisture has increased, leading to heavier rainfall events. Since 2016, UK winters have become significantly wetter, and globally, heavy rainfall events are more frequent. Hurricane Melissa in October 2025, for instance, saw its extreme rainfall intensified by climate change.
Drought conditions are also worsening in many regions due to shifting rainfall patterns and heatwave-induced evaporation. Europe experienced record low river levels, and severe droughts were declared in parts of England and Wales. Climate change made extreme dry conditions 40% more likely in Jamaica and 30% more likely in Puerto Rico.
Furthermore, climate change creates conditions ripe for wildfires. Extreme heat dries out vegetation, leading to faster fire spread. This summer, fires in Canada were twice as likely due to enabling conditions, and in January 2026, fires in Chile and Argentina burned 36% larger areas due to climate change. Extreme wildfires are projected to become more frequent and intense globally.
