2022 in Review: Global Temperature
KEY CONCEPTS
Averaging NASA and NOAA data, Climate Central's analysis shows that 2022 was 2.03°F (1.13°C) warmer than the beginning of the 20th century.
Despite the relative global cooling effect of the third consecutive La Niña year, 2022 still ranked as the sixth hottest year on record, averaging NASA and NOAA data.
2022 has been added to the famous warming stripes—a visual representation of global temperatures since 1850 showing their striking rise due to human activities.
2022 was the planet’s sixth hottest year on record, averaging NASA and NOAA’s year-end analyses.
This year’s warmth is consistent with long-term warming trends.
The top 10 hottest years on record have all occurred in the last 13 years.
Averaging NASA and NOAA data, Climate Central’s analysis shows that 2022 was 2.03°F (1.13°C) warmer than the 1881-1910 baseline—dangerously close to the internationally-agreed goal of limiting global warming to 2.7°F (1.5°C) above pre-industrial levels.
The planet is heating up—even during a cooling phase.
December 2022 saw a La Niña, the cold phase of the El Niño Southern Oscillation (ENSO), continue for the third winter in a row.
2022’s record warmth indicates that even a global cooling phenomenon like La Niña has not been enough to even briefly mask human-caused warming.
The planet is heating up—especially in the coldest places.
The Arctic continues to warm faster than the global average—nearly four times faster. The 2022 monitoring year (October 2021-September 2022) was the Arctic’s sixth warmest on record.
The last seven years have been the Arctic's seven warmest since 1900.
In 2022, the Arctic also experienced its third wettest year of the past 72 years.
Rapid Arctic change has consequences for people, ecosystems, and livelihoods across the region.
The planet is heating up—earning another dark red stripe.
The warming stripes graphic, created by Professor Ed Hawkins, a climate scientist at the University of Reading, visualizes average global temperature annually since 1850.
A blue stripe represents a below-average annual temperature relative to the 1971-2000 average, and red an above-average temperature. 2022's stripe is dark red.
Solutions ahead
The steep rise in global temperatures since the mid-20th century reflects human-caused emissions of heat-trapping greenhouse gases, which continued to climb in 2022.
The good news is that there are many opportunities to cut emissions in 2023 and beyond.
The latest IEA report charts unprecedented acceleration in renewable energy around the world.
By 2027, renewables are projected to be the largest source of electricity globally—exceeding coal.
China, the United States and India are all expected to double their renewable capacity expansion by 2027, accounting for two-thirds of global growth.

METHODOLOGY
Calculations of average annual global temperature are performed independently at NASA and NOAA. Small differences in their calculations arise as NASA’s calculations are extrapolated to account for polar locations with poor station coverage, while NOAA relies more heavily on the polar station data. Climate Central compares temperatures to an earlier 1880-1910 baseline to assess warming during the industrial era. Calculations of 2016 and 2020 showed a virtual tie (2016: 1.254°C, 2020: 1.250°C). The “warming stripes” was conceived and calculated by Ed Hawkins, as described here.
