(Seriously, check out this index page covering all the ENSO blog posts to date.) But there is more to ENSO than physics and humans! Blasphemy, I know.

Because, from the very beginning, ENSO has been a tale about marine life impacts. You simply cannot tell the story of El Niño, for instance, without mentioning its impacts on the anchovy fishery off the coast of Peru or across the ecologically rich Galapagos Islands, a story we covered here.
