The Nino index (Nino3.4) has just reached Nino-neutral, but global SST (sea surface temperature) has matched the highest level for this date, which was achieved during the last El Nino. Super warming is clear. Look for a global temperature soon of at least +1.7C, even if the "Super" El Nino turns out to be half-baked. The University of Maine Climate Change Institute has a spectacular interactive graphic that they update daily. It is a valuable research and communications tool.
