” The reason for the warming trend is that human activities continue to pump huge amounts of greenhouse gases into the environment, and the long-lasting planetary effects will also continue,” said Gavin Schmidt, director of GISS, NASAs leading center for climate modeling.
1880– 2022.
Human-driven greenhouse gas emissions have rebounded following a short-lived dip in 2020 due to the COVID-19 pandemic. Recently, NASA scientists, along with global scientists, determined carbon dioxide emissions were the highest on record in 2022. NASA also identified some super-emitters of methane– another effective greenhouse gas– using the Earth Surface Mineral Dust Source Investigation (EMIT) instrument that launched to the International Space Station last year.
The Arctic area continues to experience the greatest warming patterns– near to 4 times the global average– according to GISS research study provided at the 2022 yearly conference of the American Geophysical Union, in addition to a different research study.
Communities around the globe are experiencing effects scientists see as connected to the warming atmosphere and ocean. Environment change has actually magnified rains and tropical storms, deepened the severity of dry spells, and increased the impact of storm surges. Last year brought torrential monsoon rains that ravaged Pakistan and a consistent megadrought in the U.S. Southwest. In September, Hurricane Ian became one of the strongest and costliest typhoons to strike the continental U.S.

NASAs global temperature analysis is drawn from information gathered by weather stations and Antarctic research stations, as well as instruments installed on ships and ocean buoys. NASA scientists evaluate these measurements to represent uncertainties in the data and to maintain consistent techniques for calculating global average surface area temperature level differences for every single year. These ground-based measurements of surface temperature follow satellite data gathered since 2002 by the Atmospheric Infrared Sounder on NASAs Aqua satellite and with other price quotes.
NASA utilizes the period from 1951– 1980 as a baseline to understand how worldwide temperatures alter in time. That baseline includes environment patterns such as La Niña and El Niño, along with cold or unusually hot years due to other elements, ensuring it encompasses natural variations in Earths temperature level.
Many aspects can affect the average temperature level in any given year. 2022 was one of the warmest on record in spite of a third consecutive year of La Niña conditions in the tropical Pacific Ocean. NASA scientists approximate that La Niñas cooling impact might have lowered global temperatures slightly (about 0.06 ° C or 0.11 ° F )from what the average would have been under more typical ocean conditions.
A separate, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) concluded that the international surface area temperature level for 2022 was the sixth highest because 1880. NOAA researchers utilize much of the very same raw temperature information in their analysis and have a various standard duration (1901– 2000) and methodology. Rankings for specific years can vary slightly in between the records, they are in broad contract and both show ongoing long-term warming.
NASAs complete dataset of worldwide surface area temperature levels through 2022, along with complete information with code of how NASA scientists performed the analysis, are publicly available from GISS.

The bar chart listed below shows 2022 in context with temperature anomalies considering that 1880. NASAs international temperature level analysis is drawn from data collected by weather condition stations and Antarctic research stations, as well as instruments mounted on ships and ocean buoys. NASA scientists examine these measurements to account for uncertainties in the data and to preserve constant approaches for calculating international typical surface area temperature level distinctions for every year. These ground-based measurements of surface temperature are constant with satellite data collected considering that 2002 by the Atmospheric Infrared Sounder on NASAs Aqua satellite and with other price quotes.
A different, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) concluded that the global surface area temperature level for 2022 was the sixth greatest given that 1880.
Global Temperature Anomaly 2022 compared to 1951-1980 average.
In 2022, Earth was about 1.11 ° C( 2 ° F) warmer than the late 19th century average.
Earths typical surface area temperature level in 2022 tied with 2015 as the 5th warmest on record, according to an analysis by NASA. Continuing the worlds long-term warming trend, international temperatures in 2022 were 0.89 degrees Celsius (1.6 degrees Fahrenheit) above the average for NASAs baseline period (1951– 1980), according to researchers at NASAs Goddard Institute for Space Studies (GISS).
The previous nine years have actually been the hottest years given that contemporary recordkeeping started in 1880. This suggests Earth in 2022 had to do with 1.11 ° C( 2 ° F) warmer than the late 19th century average.
The map above illustrates international temperature level anomalies in 2022 It does disappoint outright temperatures; instead, it shows how much warmer or cooler each area of Earth was compared to the average from 1951 to 1980. The bar chart below programs 2022 in context with temperature abnormalities because 1880. The worths represent surface temperatures balanced over the entire globe for the year.
