An independent analysis by NASA and the National Oceanic and Atmospheric Administration have found that earth's global surface temperatures in 2018 were the fourth warmest since 1880.
Average global surface temperatures were 1.0 degree Celsius (1.8 Fahrenheit) above pre-industrial times in 2018, the U.N.'s World Meteorological Organization (WMO) said, based on data from U.S., British, Japanese and European weather agencies. The announcement was delayed several weeks due to the government shutdown that resulted in many NOAA and NASA employees being furloughed.
"Never mind the little wiggles from year to year".
The records have all been tallied and all the major player are in agreement: Earth just went through its fourth hottest year on record, and it's only going to get hotter in the years to come. "Those who live in denial of this fact are in denial of physics".
"2015 was the first year that global annual average surface temperatures reached 1.0 °C above pre-industrial levels and the following three years have all remained close to this level", Adam Scaife, head of Long-Range Prediction at the Met Office, said Wednesday in a news release.
"The degree of warming during the past four years has been exceptional, both on land and in the ocean".
Outside scientists, such as Natalie Mahowald of Cornell University, said that the forecast was consistent with what researchers know about warming and natural variability.
The United Nations says the world is now on track for a temperature rise of 3C or more by 2100. Scientists warn that if we're to avoid the worst affects of climate change, we cannot allow the temperature to rise more than 2 degrees compared to pre-industrial levels. Taking this into account, NASA estimates that 2018's global mean change is accurate to within 0.1 degree Fahrenheit, with a 95 percent certainty level.
Nine eastern states had their wettest years on record, "an exclamation point on a trend of big rain" in the age of climate change, Arndt said.
The secretary general added that numerous extreme weather events are "consistent with what we expect from a changing climate".
At least 247 people died in those disasters.
