Two graphs below show a shocking rise in ocean heat content. Plus, as a result of this increase, we get heartbreaking news about the death of beautiful and life-sustaining coral reefs...
As the global sea surface temperature set a new record high on Monday at 21.17C, following months of above-average temperatures, scientists are raising the alarm about a potential fourth mass coral bleaching event.
Derek Manzello of the US National Oceanic and Atmospheric Administration (NOAA) said it was likely that the entire Southern Hemisphere would experience bleaching this year.
“We are literally sitting on the cusp of the worst bleaching event in the history of the planet,” the ecologist said.
These important ecosystems exist in more than 100 countries and territories and support at least 25% of marine species. They are integral to sustaining Earth’s vast and interconnected web of marine biodiversity, and are sometimes referred to as “rainforests of the sea” for their ability to act as carbon sinks by absorbing the excess carbon dioxide in the water.
Unfortunately, coral reefs are disappearing at an alarming pace.
