No trend reversal: 2021 will probably be one of the hottest years too

Several regional climate records were broken in 2021. Land temperatures in the Northern Hemisphere were on average higher than at any time since NOAA records began in 1880.

Arctic in serious trouble

Scientists say the Arctic is warming twice as fast as the rest of the world. “The effects of man-made climate change are driving the Arctic region into a dramatically different state than it was a few decades ago,” said NOAA CEO Rick Spinrad. “These trends are alarming and undeniable. We have reached a critical moment. We must act and face the climate crisis.”

In addition, researchers are concerned about other persistent trends such as the reduced extent of ice cover in the Antarctic and higher emissions of greenhouse gases such as carbon dioxide (CO2). And the outlook for 2022 also does not promise any improvement. According to NOAA scientists, the probability is now more than 99 percent that 2022 will again be one of the ten warmest years since records began.
