(Top image shows July of 2017 global temperature anomalies compared to July of 2016 global temperature anomalies [bottom image]. July of 2016 was cooling into a weak La Nina relative to one of the strongest El Ninos on record. This year, ENSO neutral conditions prevail coordinate with rather strong polar amplification in the Southern Hemisphere as temperatures in the Southern Ocean off West Antarctica hit…
