(WASHINGTON D.C.)- a year ago was the fourth warmest since 1880, according to independent analyses by the National Aeronautics and Space Administration (NASA) and the National Oceanic Atmospheric Administration (NOAA).
Two US agencies, the United Kingdom Met Office and the WMO have analysed global temperatures in slightly different ways, but each came to the same conclusion on Wednesday: 2018 was the fourth-warmest year on record behind 2016, 2015 and 2017. 2018 saw the 14th-highest mean temperature on record in the contiguous 48 states, and it was the third-wettest year for the area despite persistent drought in the southwest and the northern plains.
"The five warmest years have, in fact, been the last five years" said Gavin A. Schmidt, director of NASA's Goddard Institute for Space Studies, the New York Times reports. The long-term trends are extremely robust. The report stated that much of the warming can be attributed to an increase in carbon emissions from human activity.More news: 13 dead in Uttarakhand after consuming spurious liquor, dozens critical
Overall, global temperatures have risen about 2 degrees Fahrenheit (1 degree Celsius) in the last 138 years. It also said that the 20 warmest years in history all occurred within the last 22 years.
A total of 6,300 weather stations, ship and buoy observations of sea surface temperatures, and Antarctic research stations were used in NASA's analyses. Indeed, that natural variation is why climate scientists look primarily at temperature trends over long timescales and don't give too much significance to a single hot or cold year.
In addition to the temperature records, the US suffered $91 billion in direct losses from extreme weather events in 2018, the fourth most since 1980, Ardnt said. Lower than normal temperatures are shown in blue.More news: Spurs v Leicester - Mauricio's preview
"The long-term temperature trend is far more important than the ranking of individual years, and that trend is an upward one", Petteri Taalas, secretary general of the World Meteorological Organization, told The Guardian. It warned that intense heatwaves "are becoming more frequent as a result of climate change". Even an increase in 1.5 could be a great risk to the stability of the world.
The 2018 global temperature reports were originally scheduled for release in mid-January, but they were delayed because the 35-day partial government shutdown prevented government scientists from finalizing their calculations.More news: Fleetwood Mac’s ex-guitarist suffers vocal cord damage during heart surgery
