The Last 5 Years The Warmest in History, Scientists Say
The past five years are the warmest in recorded history, scientists from NASA and NOAA announced Wednesday, part of a continued trend of higher temperatures around the world. “2018 is yet again an extremely warm year on top of a long-term global warming trend,” said Goddard Institute for Space Studies Director Gavin Schmidt.
In the U.S., temperatures in the southwest and parts of the East coast ranked among the warmest in history, which contributed to an entrenched drought in the southwest with overall temperatures in the country about 1.5 degrees above the 20th-century average.
Overall temperatures around the world were 1.5 degrees warmer than mean temperatures from 1951 to 1980, according to scientists at NASA’s Goddard Institute for Space Studies in New York.
The average global surface temperature has risen about 2 degrees Fahrenheit since the 1880s, which is largely driven by releases of carbon dioxide and other greenhouse gases by human activities.
Climate scientists around the world have raised the alarm about the danger of climate change and a warming climate in the last year. A major climate report from a panel of the United Nations found time is running out to drastically reduce emissions and slow warming temperatures and a U.S. government report detailed risks to various parts of the U.S. from extreme weather events and threats to the economy.
