After yesterday’s announcement that the Japan Meteorological Agency had determined that according to their data that October was the warmest on record, it should come as no surprise that NOAA has also measured the highest temperature since their records started in 1880 for both October and for the year to date, breaking the previous records set just last year. Both land and ocean temperatures set new records this month.
The graph of monthly anomalies for the globe shows that 2015 has been consistently above the six hottest years on record by a wide margin, due in part to the warm ocean waters associated with El Niño along the equator in the Pacific Ocean as well as the “blob” of warm ocean water farther north in the Pacific. In fact, according to Jason Samenow of the Capital Weather Gang, 2015 will most likely be the warmest year on record by a wide margin.
