Temperature in 2019 could be high

February 7, 2019

The average temperature on Earth was the fourth highest since measurements began.  The last five years are now the warmest in the nearly 140-year history of temperature measurements, and eighteen of the nineteen warmest years have been in this century.

The American Space Agency NASA and the United States Marine and Climate Agency (NOAA) jointly presented these results yesterday. The temperature was more than one degree above the average of the late 19th century when people first started pumping greenhouse gases into the Earth's atmosphere. The aim of the Paris Agreement is to keep temperature rising below 1.5-2 ° C. Given the current human emissions, warming could reach 3 ° C or more before the end of the century.

The last two years have not been as warm as the record year 2016. That year, the weather phenomenon El Niño in the Pacific Ocean topped on the man-made warming and boosted it. The opposite, La Niña, had a cooling effect on the average temperature of the Earth last year before a weak El Niño appeared at the end of the year.

Zeke Hausfather, a climate scientist at Berkeley Earth, an independent climate research group, believes that 2019 is likely to be the second warmest year since measurements started with the help of El Niño.

"We are no longer talking about situations where global warming is something that will happen in the future. It is here. It is now, ”said Gavin Schmidt, director of the Goddard Space Agency NASA, who monitors temperature measurements.
