Assigned: NASA reveals how hotter than average the summer of 2023 will be

The Earth recorded its hottest summer on record this year, according to data from the US space agency NASA and the National Oceanic and Atmospheric Administration (NOAA), in new maps that reveal how quickly the world’s temperature is rising.

The past three months have been the hottest summer in the Northern Hemisphere and the warmest winter in the Southern Hemisphere, NASA and NOAA said Wednesday in a statement.

The space agency, which has kept temperature records since 1880, said June, July and August collectively recorded temperatures 0.23 degrees Celsius higher than any previous summer in its records.

This figure is also 1.2°C above average summer temperatures between 1951 and 1980. Furthermore, August alone saw temperatures rise 1.2°C above normal levels.

NASA’s announcement comes after data from the World Meteorological Organization and the European Space Agency Copernicus confirmed that this summer is the hottest on record.

“Record temperatures in the summer of 2023 are not just a set of numbers, they lead to serious real-world consequences,” NASA Administrator Bill Nelson said in a statement.

“From extreme temperatures in Arizona and across the country to wildfires across Canada, and severe flooding in Europe and Asia, extreme weather threatens lives and livelihoods around the world.”

The record-breaking summer of 2023 continues a long-term warming trend, the statement said, referring to data collected by NASA’s Goddard Institute for Space Studies (GISS) in New York.

El Niño, a natural climate phenomenon characterized by higher-than-normal sea surface temperatures in the tropical Pacific Ocean, may have contributed to this record-breaking heat wave. But scientists from NASA and NOAA said the main driver behind the extreme heat is the climate crisis caused by greenhouse gases.

“Last month was not only the warmest August on record, but it was also the 45th consecutive month in the world and the 534th consecutive month in which temperatures were above average,” said Sarah Kapnick, chief scientist at the National Oceanic and Atmospheric Administration. twentieth century.

“Global marine heatwaves and a growing El Niño are driving additional warming this year, but as long as emissions continue to drive a steady march of backward warming, we expect more records to be set in the coming years.”

This year, the world has broken many temperature records, with the first week of July witnessing the highest temperatures ever for the month, and marine heat waves that shocked scientists, and recorded historic temperatures, from China to Europe and the United States.

Copernicus said earlier this month that 2023 would so far be the second hottest year on record after 2016. NASA has already confirmed that July temperatures were the hottest on record, and the agency’s scientist warned that 2024 could break the records. Standard for this year as well.

“Unfortunately, climate change is happening,” said Gavin Schmidt, a climate scientist at the University of California, California. “The things we said would happen are starting to happen. And it will get worse if we continue to emit carbon dioxide and other greenhouse gases into our atmosphere.” NASA.
