2022 Was The 5th Warmest Year Ever Recorded: NASA
According to an analysis by (NASA), Earth’s average surface temperature in 2022 tied to 2015 is the fifth hottest on record.
Continuing the planet’s long-term warming trend, the global temperature in 2022 is 1.6 degrees Fahrenheit, or 0.89 degrees Celsius, well above the 1951-1980 NASA baseline average. , scientists from NASA’s Goddard Institute for Space Studies (GISS) in New York report.
“This warming trend is alarming,” said NASA Administrator Bill Nelson.
“Our warming climate is already producing signs: Wildfires are on the rise; hurricanes are getting stronger; droughts are devastating and sea levels are rising. NASA is ramping up oranges,” said Mr. Nelson. fulfill its role in tackling climate change”.
The study says the past nine years have been the hottest since the modern record system began in 1880. This means that the Earth in 2022 will have a temperature of about 2 degrees Fahrenheit, or about 1,800 degrees Fahrenheit. 11 degrees Celsius, warmer than the late 19th century average, the study said.
“The reason for the warming trend is that human activities continue to pump large amounts of greenhouse gases into the atmosphere and the long-term effects on the planet will also be,” said Gavin Schmidt, director of GISS. continue”.
Human-generated greenhouse gas emissions have rebounded after a short-term decline in 2020 due to the COVID-19 pandemic, the study says.
Recently, NASA scientists as well as international scientists have identified the highest carbon dioxide emissions recorded in 2022, the study said.
The study says NASA has also identified several sources of super-emissions of methane – another powerful greenhouse gas – using the Earth Surface Mineral Dust Sources Survey instrument launched to the Space Station. International Headquarters last year.
The Arctic region continues to experience the strongest warming trend – nearly four times the global average – according to GISS research presented at the 2022 annual meeting of the American Geophysical Union, also as a separate study.
Communities around the world are experiencing effects that scientists consider related to warming of the atmosphere and oceans. Climate change has increased rainfall and tropical storms, exacerbated drought severity, and increased the impact of storm surge.
Last year, torrential monsoon rains ravaged Pakistan and a persistent super-drought in the southwestern United States. In September, Hurricane Ian became one of the strongest and most expensive hurricanes to hit the continental United States
NASA’s global temperature analysis is drawn from data collected by weather stations and research stations in Antarctica, as well as ship-mounted instruments and ocean buoys. NASA scientists analyzed these measurements to account for uncertainty in the data and maintain consistent methods for calculating the difference in global average surface temperatures for each year, the study said. said.
These terrestrial surface temperature measurements are consistent with satellite data collected since 2002 by NASA’s Aqua Atmospheric Infrared Detector, and with other estimates, the study says. said.
NASA uses the period 1951-1980 as a baseline to understand how global temperatures change over time. That baseline includes climate patterns like La Nina and El Nino, as well as unusually hot or cold years due to other factors, the study says, ensuring it includes natural variations in Earth’s temperature. soil.
Many factors can affect the average temperature in any given year. For example, 2022 was one of the warmest years on record, the study said, despite the third consecutive year of La Nina conditions in the tropical Pacific.
NASA scientists estimate that La Nina’s cooling effect may have caused a slight decrease in global temperatures, by about 0.11 degrees Fahrenheit or 0.06 degrees Celsius, compared with the average for oceanic conditions more typical positive.
A separate, independent analysis by the National Oceanic and Atmospheric Administration (NOAA) has concluded that the global surface temperature in 2022 is the sixth highest since 1880.
NOAA scientists used much of the same raw temperature data in their analysis, but with a different base period (1901-2000) and methodology. While the ratings for specific years differ slightly between records, the study says, they are both consistent and both reflect ongoing warming over the long term, the study said.
The study says that NASA’s full data set of global surface temperatures through 2022, as well as complete details with code on how NASA scientists conducted the analysis, are publicly available from GISS.
