The annual globally averaged sea surface temperature was the second highest on record at 1.39 degrees F (0.77 of a degree C) above the 20th-century average and just behind 2016.
"Unfortunately, we expect to see much extreme weather throughout 2020 and the coming decades, fuelled by record levels of heat-trapping greenhouse gases in the atmosphere".
2019's position as the second warmest year on record, below that of only 2016, was confirmed by NOAA, and was also confirmed by leading scientific bodies, including NASA, the World Meteorological Organisation and the British MET Office.
"We have strong man-made global warming", says Friederike Otto, a climate scientist at Oxford University.
According to NOAA, the five warmest years on record have all occurred in the period since 2015 and nine of the 10 warmest years occurred since 2005. A second NOAA analysis, released on January 8, found that, in the USA, 2019 was also the second wettest year on record, with only 1973 seeing more precipitation. In doing so, the WMO took into account slight variations in the data to come up with the global mean temperature change from pre-industrial era temperatures.
Each study compared 2019 Earth temperature data with scientists' historical records, which begin in 1880. Only December 2015 was warmer.
According to NOAA's temperature report, 2019 was also the 43rd year in a row that saw above-average global land and ocean temperatures.
"Australia had its hottest, driest year on record in 2019, setting the scene for the massive bushfires which were so devastating to people and property, wildlife, ecosystems and the environment", Taalas said. That is 1.71 degrees (0.95 C) higher than the average of the 20th century and 2.08 degrees (1.16 C) warmer than the late 19th century.
And Boris Johnson says he wants the United Kingdom to lead the world on climate change.
The longterm warming also seems to have a direct effect on the increase of extreme weather events, such as heatwaves, wildfires, and intense precipitation, NASA reported. The a year ago Earth was cooler than the 20th century average was 1976, before Democratic presidential candidate Pete Buttigieg, French President Emmanuel Macron and Donald Trump Jr. were born.
Rising global temperatures have been driven by human-induced global warming, with increasing concentrations of greenhouse gasses in the Earth's atmosphere have worked to trap ever increasing amounts of heat.
