Earth Alert reports that NASA scientists found (as reported for the 1983 ENSO event) that El Nino slowed the planet's rotation by as much as 0.06 milliseconds on 5 February but the planet is picking up speed and days are now only 0.94 milliseconds longer.--
This has had an awful lot to do with much of the strange weather occurrences. It doesn't seem significant, but reality is that the winds generated by El Nino in 1997 were so strong that it literally redirected the jet stream.
Science is looking, (predicting,) another, equal to, or worse for this year beginning in May.
