2018 was the fourth-hottest year on record

The National Oceanic and Atmospheric Administration, or NOAA, along with the space agency NASA, released a report on Wednesday on last year's temperature data from around the world.

Scientists with NASA and NOAA will discuss the Earth's 2018 global temperatures and climate conditions on February 6, 2018.

According to NOAA, 2016 was the warmest year on record, followed by 2015 and 2017 in second and third place.

Global temperatures averaged 1.49 degrees Fahrenheit above the 1951-1980 average according to NASA data, while NOAA showed 1.42F above the 1901-2000 average. The warming trends are most evident in the Arctic, NASA said.

Even an increase of 1.5 degrees will have dire consequences, according to the United Nations science panel on climate change. It was the fourth highest since 1880, the earliest year for which records are available.

Using computer simulations, the British weather office forecast s that the next five years will average somewhere between 58.51 and 59.49 degrees (14.73 to 15.27 Celsius).

"2018 is yet again an extremely warm year on top of a long-term global warming trend", Gavin Schmidt, director of GISS, said in a statement. But in the long-term, the two agencies strongly agree on the pace and trajectory of global warming.

Neal, of MA , has delegated the task to his oversight subcommittee, which holds its first hearing Thursday on the matter. So, Suozzi said, there hasn't been a need for the chairman of House Ways and Means to seek a president's tax returns.

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.

The human toll also was high, with 247 killed and many more injured in weather and climate disasters. Lower than normal temperatures are shown in blue.

The World Meteorological Organization announced similar findings Wednesday. That would be warmer than the last four years.

The November report warned that climate change will intensify over the century without swift emissions cuts.

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

Dr. Schmidt spoke of these markers not as cliffs that the world would plunge over, however, but part of a continuing slide toward increasing levels of harm.

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.
