2018 Fourth Hottest Year On Record, Says NASA

Scientists from NASA Godard Institute for Space Studies and The National Oceanic and Atmospheric Administration (NOAA) have released data from 2018.

U.S. government scientists have announced that the Earth's average temperature was the fourth hottest on record in 2018.

The last five years rank as the hottest on record globally-far and away hotter than previous years with temperatures running roughly 1 degree Celsius warmer than pre-industrial times. It predicted that global temperatures will continue to rise over the next five years, with a 10% chance that we'll breach the mark of 1.5 °C above preindustrial levels. Their separate analyses add to decades of evidence that the burning of fossil fuels, the clearing of forests and other human activities are releasing heat-trapping greenhouse gases into the atmosphere and causing the planet to warm.

"2018 is yet again an extremely warm year on top of a long-term global warming trend", said Gavin Schmidt, director of NASA's Goddard Institute for Space Studies.

NASA's global temperature analyses use surface temperature recordings from 6,300 weather stations around the world, incorporating ship- and buoy-based measurements of ocean surface temperatures as well as measurements of surface temperatures from Antarctic research outposts.

In fact, 2018 was the wettest year in the last 35 years.

The past five years are the warmest years in modern record.

The records also show that the annual temperature of the Old Continent increased at an average rate of 0.12 Celsius degrees per decade since 1910, although it has nearly quadrupled to 0.43 Celsius since 1981.

Earth's long-term warming trend can be seen in this visualization of NASA's global temperature record, which shows how the planet's temperatures are changing over time, compared to a baseline average from 1951 to 1980.

Due to the dynamic character of global weather patterns, not every place of the Earth experiences the same levels of warming. In the past 5 years, the annual average rose to 12.6.

Arndt says 2018 "was an exclamation point, I think, on a trend that we're seeing toward more big rain, particularly in the eastern United States". Instead, his administration is working to unravel Obama-era environmental rules in favor of policies that would allow more greenhouse gas emissions from cars, trucks and coal-fired power plants. Right behind Michael were the western US wildfires and Hurricane Florence, which both racked up $24 billion in damages, according to NOAA.
