Earth has sweltered through its hottest Northern Hemisphere summer ever measured, with a record warm August capping a season of brutal and deadly temperatures, according to the World Meteorological Organization.
Last month was not only the hottest August scientists ever recorded by far with modern equipment, it was also the second hottest month measured, behind only , WMO and the European climate service Copernicus announced Wednesday.
August was about 1.5 degrees Celsius (2.7 degrees Fahrenheit) warmer than pre-industrial averages. That is the threshold that the world is trying not to pass, though scientists are more concerned about rises in temperatures over decades, not merely a blip over a month香蕉视频直播檚 time.
The 香蕉视频直播� more than 70% of the Earth香蕉视频直播檚 surface 香蕉视频直播� were the hottest ever recorded, nearly 21 C (69.8 F), and have set high temperature marks for three consecutive months, the WMO and Copernicus said.

So far, 2023 is the second hottest year on record, behind 2016, according to Copernicus.
Scientists blame ever warming from the burning of coal, oil and natural gas with an extra push from a , which is a temporary warming of parts of the Pacific Ocean that changes weather worldwide. Usually an El Nino, which started earlier this year, adds extra heat to global temperatures but more so in its second year.
Climatologist Andrew Weaver said the numbers announced by WMO and Copernicus come as no surprise, bemoaning how governments have not appeared to take the issue of global warming seriously enough. He expressed concern that the public will just forget the issue when temperatures fall again.
香蕉视频直播淚t香蕉视频直播檚 time for global leaders to start telling the truth,香蕉视频直播� said Weaver, a professor at the School of Earth and Ocean Sciences at the University of Victoria in Canada. 香蕉视频直播淲e will not limit warming to 1.5 C; we will not limit warming to 2.0 C.

Copernicus, a division of the European Union香蕉视频直播檚 space program, has records going back to 1940, but in the United Kingdom and the United States, global records go back to the mid 1800s and those weather and science agencies are expected to soon report that the summer was a record-breaker.
香蕉视频直播淲hat we are observing, not only new extremes but the persistence of these record-breaking conditions, and the impacts these have on both people and planet, are a clear consequence of the warming of the climate system,香蕉视频直播� Copernicus Climate Change Service Director Carlo Buontempo said.
Scientists have used tree rings, ice cores and other proxies to estimate that temperatures are now warmer than they The world has been warmer before, but that was prior to human civilization, seas were much higher and the poles were not icy.
So far, daily September temperatures are higher than what has been recorded before for this time of year, according to the
While the world香蕉视频直播檚 air and oceans were setting records for heat, Antarctica continued to set records for low amounts of sea ice, the WMO said.
香蕉视频直播淎ntarctic sea ice extent was literally off the charts, and the global sea surface temperature was once again at a new record,香蕉视频直播� WMO香蕉视频直播檚 secretary-general, Petteri Taalas, said in a statement released to the media. 香蕉视频直播淚t is worth noting that this is happening BEFORE we see the full warming impact of the El Nino event, which typically plays out in the second year after it develops.香蕉视频直播�
A strong El Nino coincided with the all-time high temperatures in 2016. The U.N. weather agency earlier this year that suggest Earth would within the next five years have a year that averages 1.5 degrees Celsius warmer than in the mid 19th century. Each year at or near 1.5 matters.
It also predicted 98% chance of breaking the 2016 record between now and 2027.
The new readings on high global temperatures came as WMO released Wednesday on air quality and climate, noting that extreme heat, compounded by wildfires and desert dust, has had a measurable impact on air quality, human health and the environment.
WMO scientific adviser Lorenzo Labrador lamented the deteriorating air quality around the globe and cited 香蕉视频直播渞ecord-breaking wildfire season香蕉视频直播� in many parts of the world, including western Canada and Europe.
香蕉视频直播淚f heat waves increase as a result of El Nino, we may probably expect a further degradation in air quality as a whole,香蕉视频直播� he said.
