" the problem is the solution… " Algal blooms, whether on the beach at Cancun or the Lincoln Memorial Reflecting Pool, are not new. Drawing down CO₂ and burying organic carbon in sediments is part of Gaia’s regulatory system. 14,000 years ago, during the Antarctic Cold Reversal, there were massive blooms of the haptophyte Phaeocystis in the Southern Ocean. The resulting biological pump exported large amounts of organic carbon to depth, contributing to a measurable slowdown in the rise of atmospheric CO₂ during a critical transition phase between glacial Earth and interglacial Earth, preventing a Hothouse Earth acid reflux. Had that not occurred, runaway greenhouse warming could have ended our species. During the Jurassic and Cretaceous, several Oceanic Anoxic Events (183 million years ago, 120.5 million years ago, and 94 million years ago) were marked by widespread low-oxygen conditions and extraordinary organic carbon burial. These anoxic conditions favored, ...
