☆ The world successfully tackled a dangerous pollutant. But did it accidentally warm the planet in the process?

These ghost clouds look beautiful, but they are a visible sign of deadly air pollution. Of all of the theories, however, the impact of shipping regulations is swiftly becoming one of the most discussed. But this is not an argument against cutting air pollution, Diamond said, it’s an argument for tackling it alongside reducing carbon emissions. The cooling impact of air pollution is far outweighed by the heating impact of burning fossil fuels. It’s when air pollution is tackled without also reducing carbon emissions, that “we can get into trouble,” Diamond said.

Last month smashed through the previous October temperature record, from 2019, by a massive margin, the EU's Copernicus Climate Change Service (C3S) said. The record-breaking October means 2023 is now "virtually certain" to be the warmest year recorded, C3S said in a statement. "When we combine our data with the IPCC, then we can say that this is the warmest year for the last 125,000 years," Burgess said. The only other time before October a month breached the temperature record by such a large margin was in September 2023. Michael Mann, a climate scientist at University of Pennsylvania, said: "Most El Nino years are now record-breakers, because the extra global warmth of El Nino adds to the steady ramp of human-caused warming."

Last year was 1.26 degrees Celsius (2.27 degrees Fahrenheit) warmer and this year is likely to blow past that, according to scientists. Even though the carbon budget looks to run out early in the year 2029, that doesn’t mean the world will instantly hit 1.5 degrees warmer than pre-industrial times. People should not misinterpret running out of the budget for 1.5 degrees as the only time left to stop global warming, the authors said. “If we are able to limit warming to 1.6 degrees or 1.65 degrees or 1.7 degrees, that’s a lot better than 2 degrees. Lamboll said limiting warming to 1.5 degrees is technically possible, but politically is challenging and unlikely.

REUTERS/Guglielmo Mangiapane/File PhotoSummaryCompanies Breaks previous record set in July 2019, by 0.2CHeatwaves searing Europe, North America and ChinaEarth may not have been this hot in 120,000 years - studyJuly 27 (Reuters) - July 2023 is set to upend previous heat benchmarks, U.N. Secretary-general António Guterres said on Thursday after scientists said it was on track to be the world's hottest month on record. Short of a mini-Ice Age over the next days, July 2023 will shatter records across the board," Guterres said in New York. It is statistically robust," said Piers Forster, a climate scientist at Leeds University in Britain. July is traditionally the hottest month of the year, and the EU said it did not project August would surpass the record set this month. However, scientists expect 2023 or 2024 will end up as the hottest year in the record books, surpassing 2016.

Sea temperatures also broke April and May records. Global average sea surface temperatures hit 21C in late March and have remained at record levels for the time of year throughout April and May. Australia's weather agency warned that Pacific and Indian ocean sea temperatures could be 3C warmer than normal by October. Though this year's high sea temperatures are caused by a "perfect combination" of circumstances, the ecological impact could endure, she said. The Worldwide Fund for Nature, however, warned of a "worrying lack of momentum" during climate talks in Bonn this month, with little progress made on key issues like fossil fuels and finance ahead of November's COP28 climate talks in Dubai.
