New Study: Recent ‘Unprecedented’ Cloud Cover Decline Driving Modern (And Past) Climate Change
By Kenneth Richard on 25. March 2025
“[T]he increase in absorbed solar radiation is primarily due to natural variations in cloudiness and surface albedo, which have served as the main forcing factors of the flux above the atmosphere over the last 2 decades.” – Diodato et al., 2025
It is commonly accepted that there has been a satellite-observed (CERES) cloud cover albedo decline that has led to an increase in solar radiation absorbed by the Earth’s oceans. This increasing trend in absorbed solar radiation (ASR) explains the post-2000 global-scale temperature increase (Dübal and Vahrenholt, 2021, Loeb et al., 2021, Stephens et al., 2022, Koutsoyiannis et al., 2023, Loeb et al., 2024, Nikolov and Zeller, 2024).
And now, in two new studies (Diodato et al., 2024 and Diodato et al., 2025), scientists have begun formulating reconstructions of cloud cover over the Mediterranean region that can be dated all the way back to the Medieval Warm Period, or 970 CE.
The authors suggest their reconstructions of cloud cover may be representative of more than just this region, as it is a product of large scale processes that may “transcend geographical boundaries.” In other words, what happens in the Mediterranean region may well have global implications.
