Rains arrived in California during January 2016, but the drought remains.

The globally averaged sea surface temperature in 2013 was among the 10 highest on record, with the North Pacific reaching an historic high temperature. ENSO-neutral conditions and a negative Pacific Decadal Oscillation pattern had the largest impacts on global sea surface temperature in 2013.

El Niño and La Niña conditions occur when abnormally warm or cool waters accumulate in tropical latitudes of the central and eastern Pacific Ocean. The Oceanic Nino Index is the tool NOAA scienitsts use to watch for these temperature changes. 

Was El Niño to blame for the above-average temperatures during November and December 2015?  As always, the answer is not that simple.  

El Niño is a global phenomenon. Guest blogger Dr. Andrew Watkins shines some light on El Niño's impact across the world in Australia.
