NASA says 2022 was one of the hottest years on record and things are getting worse

Last year was one of the hottest on our planet: the average surface temperature in 2022 was in fifth place compared to 2015. A report by a team of scientists from NASA’s Goddard Institute for Space Studies (GISS) in New York — the space agency’s lead center for climate modeling — shows that global temperatures in 2022 were 1.6 degrees Fahrenheit above the average for the space agency’s base period. (1951). -1980).

Data dating back to 1880 shows that the last nine years have been the warmest, meaning that the Earth in 2022 was about 2 degrees Fahrenheit warmer than the average at the end of the 19th century. The data is consistent with findings from the National Oceanic and Atmospheric Administration, also released Thursday in a separate independent study, that 2022 will be the sixth warmest year on record since 1880. In a NASA press release, space agency administrator Bill Nelson called the long-term warming trend “worrisome.”

“Our warming climate is already making itself felt: wildfires are getting worse, hurricanes are getting stronger, droughts are wreaking havoc, and sea levels are rising,” Nelson said. “NASA is strengthening our commitment to doing our part to tackle climate change. Our Earth System Observatory will provide state-of-the-art data to support our climate modeling, analysis and forecasts to help humanity confront our planet’s changing climate.”

The rise in temperature comes as a result of anthropogenic greenhouse gas emissions, which have recovered from a brief drop due to the slowdown in economic activity during the COVID-19 pandemic. Carbon dioxide emissions were the highest on record in 2022, NASA and international scientists have found. “The reason for the warming trend is that human activities continue to release huge amounts of greenhouse gases into the atmosphere, and long-term planetary impacts will also continue,” Gavin Schmidt, director of GISS, said in a press release.

NASA scientists also reported that 2023 is likely to be warmer than 2022, helped by the La Niña climate model, which leads to a slight decrease in global temperatures. The scientists calculated that La Niña’s cooling effect may have slightly reduced global temperatures, by about 0.11 degrees Fahrenheit, compared to the average in more typical ocean conditions.

GISS reports that the Arctic region continues to be hit hardest by the warmest trends, nearly four times the global average. However, communities around the world are suffering from climate change, which, according to GISS, has led to increased rainfall and tropical storms, increased drought severity, and heightened storm surge impacts.
