Climate models help us understand how the climate system works, project future climate change, and provide evidence that supports international assessments such as exposed on the IPCC. At this point, there is a fundamental question that is rarely discussed and solved: Can we access and reproduce the climate models used throughout the history of the Coupled Model Intercomparision Project (CMIP)?

Every time something burns incompletely —whether in a car engine, a factory furnace, a cooking fire, an agricultural field set alight after harvest, or a vast wildfire sweeping through savanna grasslands— tiny particles of black carbon are released into the atmosphere. You might know these more simply as soot. These particles are so small that thousands of them laid side by side would barely stret ...[Read More]

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

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

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]
