Another New Study Links Modern And Past Global Warming To Natural Changes In Cloud Cover, Not CO2

Cloud cover changes are a “top-down dynamical driver” of Earth’s climate. A July 2026 Environmental Research Letters paper authored by Bellocchi et al. attributes ~80% of the rise in Earth’s absorbed solar radiation since 2000 to declining high-reflectivity cloud cover, primarily from circulation-driven contraction of storm-cloud zones. The study highlights the climate’s “albedo governance,”…
