4th Hottest Year On Record, Arctic Warming Faster

4th Hottest Year On Record, Arctic Warming Faster

The National Aeronautics and Space Administration (NASA) is reporting that 2018 was the fourth warmest year on record since 1880.

According to a news release, NOAA found that the average global temperature was 1.42 degrees Fahrenheit above the 20th century average.

The data means that the five warmest years in recorded history have been the last five, and that 18 of the 19 warmest years have occurred since 2001.

According to NASA's Goddard Institute for Space Studies (GISS), the global temperature for 2018 was 1.5 degrees Fahrenheit warmer than the mean global temperature for the years 1951-1980.

"2018 is yet again an extremely warm year on top of a long-term global warming trend", Schmidt said in a press release. "There's no question." And the cause is clear too, he adds: "It's because of the increases in the greenhouse gases that we put into the atmosphere over the last 100 years". From last year's devastating hurricanes and coastal floods to last week's polar vortex, scientists already have plenty of disastrous phenomena to hold up as immediately evident repercussions of manmade environmental damage. It's easy, if someone is skeptical to look at a hot year and say it's meaningless, we've been here before.

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


Think global warming is not real?

Global warming is also increasingly evident in local measurements, where daily records for high temperatures are toppling more than twice as often as daily records for low temperatures, said Gerald Meehl, a senior scientist at the National Center for Atmospheric Research.

Both the sea surface temperature and the land surface temperature ranked the fourth highest on record, according to NOAA. "The global average temperature between now and 2023 is predicted to remain high, potentially making the decade from 2014 the warmest in more than 150 years of records". In the past 5 years, the annual average rose to 12.6.

"Many of the extreme weather events are consistent with what we expect from a changing climate", he said.

"Despite the recent cold snap across the Midwest and East Coast, the planet is still heating up, and the warming is unprecedented". These included two Atlantic hurricanes, Michael and Florence, several heavy rain events and unprecedented fires in the West.
