On Monday, NASA released its latest monthly temperature data for the globe. And it’s perhaps no surprise that this November was the warmest on record for the planet. The Japan Meteorological Agency’s dataset also shows the same record warmth for the month...November marks the second month in a row the global average temperature was more than 1°C (1.8°F) above the 1951-1980 baseline period NASA uses. October and now November are the first time in NASA’s dataset that a given month has been a full degree Celsius above average....Now with the two of the most anomalously warm months ever recorded, the answer is “by a lot.” This year will mark the first time that the annual global average temperature will be 1°C above pre-industrial levels. The extreme El Niño warming the tropical Pacific has had some influence on the planetary heat. But the main driver has been the accumulation of greenhouse gases in the Earth’s atmosphere, according to an analysis by Climate Central and its partners.
