Earth has had its hottest northern hemisphere summer on record, with a record-warm August capping off a season of brutal and deadly temperatures, according to the World Meteorological Organization.
Last month was not only the hottest August ever recorded by scientists using modern equipment, but also the second-hottest month measured, after July 2023The World Meteorological Organization and Copernicus, the European climate service agency, announced on Wednesday.
Temperatures in August were about 1.5 degrees Celsius (2.7 degrees Fahrenheit) above the pre-industrial average. That’s the threshold the world is trying not to cross, even though scientists are more concerned with rising temperatures over decades than just blips within a month.
this world ocean More than 70 percent of the planet’s surface was the hottest on record, approaching 21 degrees Celsius (69.8 degrees Fahrenheit), and the hottest three months in a row, the WMO and Copernicus said.
“Dog days don’t just bark, they bite,” UN Secretary-General António Guterres said in a statement. “The climate breakdown has already begun.”
According to Copernicus, so far, 2023 is the second-hottest year on record, trailing only 2016.
Scientists Blame Climate Warming man-made climate change from the combustion of coal, oil and natural gas and from Natural El Niño, which is a temporary warming in parts of the Pacific Ocean that changes weather around the world. Normally, an El Niño that started earlier in the year brings extra heat to global temperatures, but more so in the following year.
Climatologist Andrew Weaver said the figures released by the World Meteorological Organization and Copernicus were not surprising, and he regretted that governments did not seem to be paying enough attention to global warming. He fears the public will forget about the issue when temperatures drop again.
“It’s time for global leaders to start telling the truth,” said Weaver, a professor at the School of Earth and Ocean Sciences at the University of Victoria in Canada. “We will not limit warming to 1.5C;”
Copernicus, a division of the European Union’s space programme, has records dating back to 1940, but in the UK and US, global records date back to the mid-1800s, and these weather and science agencies are expected to soon report that the summer was a record-breaker By.
“What we’re seeing, not just new extremes, but the persistence of these record-breaking conditions, and their impact on people and the planet, is the result of a warming of the climate system,” said Caro, director of the Copernicus Climate Change Service. Obvious consequences,” Buontampo said.
Scientists use tree rings, ice cores and other indicators to estimate that temperatures are now warmer than they actually are. It has a history of about 120,000 years. The world has warmed before, but that was before human civilization, the oceans were much higher and the poles were not frozen over.
According to the Bureau of Meteorology, so far in September, daily temperatures have been higher than those recorded for this time of year. Climate Reanalyzer at the University of Maine.
While the world’s air and seas have been hotter than ever before, Antarctica continues to see record amounts of sea ice, the World Meteorological Organization said.
“Antarctic sea ice extent is indeed off the charts, with global sea surface temperatures setting new records again,” WMO Secretary-General Petteri Taalas said in a statement to the media. This happened before we saw the full warming impact of an El Niño event, which typically manifests itself in the second year after it develops.”
A strong El Niño coincided with record high temperatures in 2016.The United Nations weather agency earlier this year launch forecast This suggests that the Earth will be on average 1.5 degrees Celsius warmer over the next five years than it was in the mid-19th century. 1.5 or close to 1.5 per year is important.
It also predicts a 98 percent chance of breaking the 2016 record between now and 2027.
The World Meteorological Organization released new data on global heat on Wednesday its latest announcement Regarding air quality and climate, it noted that extreme heat, combined with wildfires and desert dust, had significant impacts on air quality, human health and the environment.
Lorenzo Labrador, scientific adviser to the World Meteorological Organization, lamented deteriorating air quality around the world, citing a “record-breaking wildfire season” in many parts of the world, including western Canada and Europe.
“If El Niño led to an increase in heat waves, we might expect further deterioration in overall air quality,” he said.
