Great Barrier Reef Warming, Coral Bleaching Driven By Cloud Radiative Forcing, Not Humans

For decades Great Barrier Reef (GBR) warming and coral bleaching have often been assumed to be driven by human greenhouse gas emissions and/or El Niño events. But a new study finds a much larger and more robust correlation between natural cloud cover modulation of solar radiation, shallow-water warming, and bleaching.
It has taken over 260 years for the net total radiative forcing from CO2 to allegedly rise by a grand net total of 1.82 W/m².
But a new study reveals that a commonly-observed 20% decrease in cloud cover over the GBR exposes this region to an additional 30 W/m² of direct solar radiation for weeks, months at a time. This dramatically warms shallower waters and, more importantly, the enhanced shortwave radiation perpetually exposes corals to UV bleaching.
