Sudden Temperature Change in a Warming World: Why Future Temperature Swings Are a Global Tug-of-War?

Kalpana Hamal July 10, 2026

Day-to-day temperature changes in Berlin, June 15–30, 2026. Red bars = Extreme warming, and blue bars = Extreme cooling. The red line shows the daily mean temperature. Data: ERA5 via Open-Meteo.

Berlin just went through a brutal heatwave, and then out of nowhere, the temperature crashed between June 28 and 29. The daily mean temperature dropped from nearly 33°C to 25°C—a dramatic drop of about 8°C in just 24 hours (based on ERA5 reanalysis data structure accessed via Open-Meteo). Scientists call these abrupt shifts temperature volatility: rapid transitions from unusually cold to warm cond ...[Read More]

Weaker but more frequent: how sea breezes are changing in a warming climate

Shalenys Bedoya-Valestt and Cesar Azorin-Molina May 26, 2026

For the 500 million people living along the Mediterranean coast, the sea breeze is an essential component of the regional climate. They are more than a pleasant coastal wind, as they are critical for easing summer heat stress, dispersing pollutants, and triggering convection (the rapid upward movement of warm, moist air), sometimes leading to severe storms, among many others. But the Mediterranean ...[Read More]

Introduction Human-caused climate change is increasing the frequency of extreme weather events around the world, and Europe is no exception. These events typically last from a few days to several weeks or even months. Using climate models and reanalysis products, scientists are studying how extreme weather events will evolve and where they are likely to become more frequent and intense in a warmin ...[Read More]
