2018 was 4th Warmest, but Next 5 Years Could Break Records

Paris: The last four years were the hottest since global temperature records began, the United Nations confirmed on Wednesday in an analysis that it said was a "clear sign of continuing long-term climate change". 2018 proved that by setting the record as the Earth's fourth highest surface temperature in the nearly 140 years of recording these metrics.

The world temperature in 2018 was the fourth hottest ever recorded, only next to 2016 (the warmest), 2015 and 2017, say the specialists of the National Administration of Aeronautics and Space (NASA).

The new report said the world was on track to have average global temperatures rise to 3 degrees Celsius by 2100, as record levels of man-made greenhouse gas emissions, mainly from burning fossil fuels, is trapping more heat in the Earth's atmosphere.

Global warming is also increasingly evident in local measurements, where daily records for high temperatures are toppling more than twice as often as daily records for low temperatures, said Gerald Meehl, a senior scientist at the National Center for Atmospheric Research.

"We're no longer talking about a situation where global warming is something in the future", said Gavin A. Schmidt, who is the director of the Goddard Institute for Space Studies.


NASA and NOAA independently monitor the Earth's surface temperatures and changes based on observations of both land areas and oceans, using a network of satellites scattered in Earth orbit. "The long-term temperature trend is far more important than the ranking of individual years, and that trend is an upward one", said WMO Secretary-General Petteri Taalas. But if you look at two, three, four, now five very warm years, then it is much harder to dismiss that.

The data indicate that global warming shows no sign of stopping. Higher than normal temperatures are shown in red.

The human toll also was high, with 247 killed and many more injured in weather and climate disasters. But in the contiguous 48 states, 2018 marked the 14th warmest on record. The release of the NASA/NOAA report was delayed by the USA government shutdown.

The World Meteorological Organization announced similar findings Wednesday.

But the US did get soaked in 2018, says Deke Arndt, a climate scientist with NOAA.
