MEERTALK April 2025

FEWER CLOUDS MORE WARMING
Contraction of World’s Storm-Cloud Zones Adds to Earth’s Sunlight Absorption

During this MEERTALK, Dr. Tselioudis will present compelling evidence from satellite data showing that over the past 23 years, the world’s storm-cloud zones have contracted at a rate of 1.5-3% per decade. This contraction has allowed more solar radiation to penetrate the Earth’s surface, making it the most significant factor in the observed 21st-century trend of increased solar absorption. Dr. Tselioudis will discuss how this mechanism may serve as a powerful positive feedback loop in climate warming, with far-reaching implications for our planet’s future.

Dr. George Tselioudis is a renowned expert at NASA’s Goddard Institute for Space Studies. His research focuses on analyzing satellite observations and model simulations to explore how atmospheric dynamics and thermodynamics interact with the Earth’s energy and water cycles. Through his work, he quantifies the critical feedbacks these processes have on climate change.
