This cyclical weather phenomenon has apparently finally arrived. NOAA said it started in March 2015, although few of the physical signs appeared. The link below shows Australia, Japan and NOAA all agreeing … we’ll soon find out. What the article does not say is that the 1997-98 ENSO saw roughly half of the world’s corals die. In the face of global warming the corals and seagrass beds absorb a huge amount of CO2 during their photsynthesis. We’re talking similar levels of carbon-fixing to tropical rain forests; so if we get more major coral bleaching events then we are likely to be in a mess.
