2018 fourth hottest year on record

2018 fourth hottest year on record

According to a study from the Goddard Institute for Space Studies at NASA, last year saw the Earth's fourth-highest global surface temperatures when compared to almost 138 years of records.

The U.S. government's National Oceanic and Atmospheric Administration said 2018's average temperature was 58.42 degrees (14.69 Celsius), which is 1.42 degrees (0.79 Celsius) warmer than the 20th century average. 2016 now ranks as the hottest year on record, with 2017 coming in second and 2015 third. The past five years are, collectively, the warmest years in the modern record.

Since the 1880s, the average global surface temperature has risen about 2 degrees Fahrenheit (1 degree Celsius).

NASA does point out that weather dynamics affect regional temperatures, so not every region on Earth saw similar amounts of warming.

The report also noted that warming is being felt most in the Arctic, where sea ice continues to melt, raising the sea level. NASA adds that the melting of Greenland and Antarctic ice sheets contributed to a rise in sea level. It is also linked the extremely cold temperatures the Midwest and Northeast experiences last week. The record is shown as a running five-year average. It was the fourth highest since 1880, the earliest year for which records are available. This year has started with mild El Nino conditions, "which suggests 2019 will be warmer than 2018 but that's more a rule of thumb than a firm prediction", Schmidt said.

On Wednesday, Feb. 6, scientists from NASA and NOAA issued their analysis of the global climate, including its economic impact, in 2018.

NOAA and NASA scientists say that in regards to global temperatures, the foot is on the accelerator. Deathly record lows are real in the U.S., but don't be fooled by the cooling that we have been witnessing, global warming is real also.

Last year, 29 countries - including much of Europe and the Middle East - and the continent of Antarctica had their hottest years on record, said Zeke Hausfather, a climate scientist with the nonprofit research organization. Climate scientists say that the higher rainfall is largely due to warming oceans, which cause more evaporation that in turn leads to more rain.

WMO also released a report on Wednesday that the globally averaged temperature in 2018 was about 0.38 degrees Celsius above the 1981 to 2010 long-term average.

However, 2018 was actually cooler than 2015, 2016 and 2017.
