NASA reports this was the hottest July on record. So we are now in bet the mortgage territory that 2015 will be the hottest year in NASAs 125-year temperature record.
In fact, 2015 is likely to crush the previous record 2014 probably by a wide margin, especially since one of the strongest El Niños in 50 years is adding to the strong underlying global warming trend. Climate expert Dr. John Abraham updated this NASA chart to show how the first seven months of 2015 compares to the annual temperatures of previous years:
The gap between 2015 and all other years in that chart will grow since NOAA and many others project the current El Niño will keep growing stronger for many months. The soaring ocean temperatures in the central and eastern equatorial Pacific, which are characteristic of an El Niño, just keep climbing. As the journal Nature reports, this El Niño could be [the] strongest on record. It is projected to peak in the winter and last into the spring of 2016.
