For those of you interested in keeping informed about climate issues, the agency NOAA offers Climate.gov. I suggest that you bookmark the site and visit it regularly. One of their offerings is called the ENSO Blog by Michelle L’Heureux, Emily Becker (NOAA CPC), and Anthony Barnston (IRI). It addresses specific concerns about El Niño. On May 19, 2014, the ENSO Blog published an excellent summary by Barnston of the potential global and regional effects which could cascade from a strong El Niño this year. I invite you to read it and explore the other posts in this new climate blog.
