Scientists warn extreme weather events will intensify as Earth warms

American scientists warn that Earth's continued warming from greenhouse gas accumulation is already causing more frequent and intense extreme weather events. Climate researcher Daniel Swain said the world has entered a new era of climate risk, with longer heatwaves, droughts, floods, wildfires and powerful storms. The warning comes as NOAA data shows 84% of the world's corals experienced heat stress between 2023 and 2025.
Key Facts
- NOAA data shows 84% of the world's corals experienced heat stress from microscopic algae between 2023 and 2025.
- Climate scientist Sarah Perkins-Kirkpatrick said even if humanity stopped increasing greenhouse gas emissions now, warming consequences would not disappear quickly because CO2 can persist in the atmosphere for hundreds of years.
- A January 2022 UK climate risk assessment put the probability of temperatures reaching 40°C or higher before 2040 at 0.02%, but that summer parts of the UK exceeded 40°C.
- Snow fell in the mountains of Almaty and Almaty region on August 24, 2026, and was confirmed by meteorologists after social media users suspected a fake.
Climate Risk Era
American climate scientist Daniel Swain told Associated Press that extreme events are becoming so frequent that the world has effectively entered a new era of climate risks. These risks include longer heatwaves, droughts, floods, wildfires and powerful storms. Scientists also warn of approaching critical tipping points after which some ecosystems may not recover. Coral reefs are experiencing severe heat stress, and Amazon forests face droughts, fires and deforestation.
Coral Bleaching
According to the National Oceanic and Atmospheric Administration, 84% of the world's corals were exposed to microscopic algae in response to heat stress between 2023 and 2025. This exposure leads to coral death, and even if temperatures dropped sharply, recovery of most corals is unlikely.
Regional Anomalies
A January 2022 UK climate risk assessment estimated a 0.02% probability of temperatures reaching 40°C or higher before 2040, but that summer parts of the UK exceeded 40°C. In the mountains of Almaty and Almaty region on August 24, 2026, snow fell, and meteorologists confirmed the event after social media users suspected a fake.
