The past seven years have been the hottest in recorded history, new data shows

Global temperatures in 2021 were among the highest ever observed, with 25 countries setting new annual records, according to scientists from NASA, the NOAA and Berkeley Earth

In the middle of a historically sweltering summer, a NASA researcher stood before Congress and declared the unvarnished, undeniable scientific truth: “The greenhouse effect has been detected,” James Hansen said. “And it is changing our climate now.”

The year was 1988. Global temperatures were about 0.6 degrees Celsius (1.1 degrees Fahrenheit) above the preindustrial average. It was, at the time, the hottest 12-month period scientists had ever seen.

None of us will ever experience a year that cool again.

In 2021, global temperatures were between 1.1 and 1.2 degrees Celsius (2.2 degrees Fahrenheit) above the preindustrial average, according to new data from NASA, the National Oceanic and Atmospheric Administration and Berkeley Earth.

Despite a La Niña weather pattern in the Pacific Ocean, which tends to cool the planet, 2021 was roughly tied for sixth-hottest year ever observed, scientists say. All of the seven hottest years on record have happened in the last seven years.
