Planet Earth’s fever continues unabated
Earth’s long-running global warming fever spiked to yet another high in November 2015, reaching a full 1.75 degrees Fahrenheit above average — the second-highest monthly departure from the norm in the 136-year record, only behind last month’s record-high departure from average.
The average land-surface temperature was the fifth-highest on record, while the average global sea surface temperature — fueled in part by a strong El Niño — was the highest ever recorded.
The global climate report was released this week by the National Oceanic and Atmospheric Administration’s National Climatic Data Center. The report makes it clear that 2015 will become the warmest year on record for planet Earth.
Climate scientists with the NCDC said they expect the warming trend to continue in near- and medium-term, despite last week’s historic global agreement to curb emissions of heat-trapping pollutants.
Most of Earth’s land surfaces were warmer than average or much warmer than average, with record warmth notable across most of equatorial and northeastern South America and parts of southeastern Asia. Parts of the western United States, southern Greenland, portions of northern Asia, and parts of southern South America were near to cooler than average. No regions were record cold in November.
In the world’s oceans, El Niño drove the eastern equatorial Pacific to record warmth. Parts of western North Atlantic, the Barents Sea in the Arctic, and much of the Indian Ocean were also record warm.
The autumn (September to November) season was also record warm, at 1.73 degrees Fahrenheit above the 20th century average, surpassing last year’s record by 0.38 degrees Fahrenheit.
Seasonally, most of the Americas from Mexico through the northern half of South America were record warm, as were scattered regions across Africa, southern and southeastern Asia, and southern Australia.
The contiguous United States observed its warmest autumn on record, with a temperature 3.3 degrees above the 20th century average, surpassing the previous record set in 1962. Every state was warmer than average.
Southern South America and parts of central Asia were near to cooler than average. No land areas observed record cold temperatures for the September–November period.
