Climate change made 2022 drought 'at least 20 times likelier'
Human-caused climate change made this summer's drought across the Northern Hemisphere at least 20 times more likely, according to a rapid analysis released Wednesday that warns such extreme dry periods will become increasingly common with global heating. . For the top one metre of soil -- known as the root zone -- this summer's dryness was made at least 20 times likelier due to global heating.
Nord Stream leaked less methane than feared: atmospheric monitor
Leaks from the Nord Stream gas pipelines released some 70,000 tonnes of the powerful greenhouse gas methane, researchers said Wednesday, less than previously thought. . Researchers from France's Atomic Energy and Alternative Energies Commission said they were "surprised" that data from monitoring stations across Europe led them to conclude that 70,000 tonnes of the planet-heating gas methane had been released.

Africa sounds caution on net zero goal ahead of COP27
Africa needs time and money to wean itself off fossil fuels in order to achieve net zero without jeopardising its future, its representatives are warning ahead of next month's climate talks.. At the same time, African countries also need to secure financing for oil and gas projects, as fossil fuel revenue is needed to finance climate adaptation measures, he told AFP. Adam pointed to data showing that most of Africa's oil and gas producers depended greatly on export revenue derived by these fuels.

Argentine scientists worried after spate of whale deaths
A string of whale deaths in recent days in southern Argentina have worried scientists, who think a micro-algae could be to blame.. Despite the recent deaths, authorities have recorded more than 1,400 whales in the Nuevo and San Jose gulfs, the largest number in more than 50 years. dm/bc/to
Nobel physics winner wanted to topple quantum theory he vindicated
American physicist John Clauser won the 2022 Nobel Prize for a groundbreaking experiment vindicating quantum mechanics -- a fundamental theory governing the subatomic world that is today the foundation for an emerging class of ultra-powerful computers.. - Quantum computing - That wasn't the view of the Nobel committee, who awarded Clauser, Alain Aspect of France, and Anton Zeilinger of Austria the world's most prestigious science prize for their pioneering work in advancing the field.
