Using LED lighting on the underside of surfboards or kayaks could deter great white shark attacks, new research suggests. An Australian-led study found lighting disrupted the ability of great whites to see silhouettes against the sunlight above, reducing the rate at which the sharks followed and attacked seal-shaped decoys. 'We think this tells us a lot about how sharks see the world and how they detect and target their prey,' Macquarie University's Prof Nathan Hart says. 'But it also potentially gives us an insight in to how we can develop a non-lethal shark deterrent.'

Exclusive: Target is 81% emissions cut compared with 1990, but activists say it must be backed by plan of action

Agreement on rules paving way for rich countries to pay for cheap climate action abroad breaks years-long deadlock

Diplomats have greenlit key rules that govern the trade of “carbon credits”, breaking a years-long deadlock and paving the way for rich countries to pay for cheap climate action abroad while delaying expensive emission cuts at home.

The agreement, reached late on the first day of Cop29 in Azerbaijan, was hailed by the hosts as an early win at climate talks that have been snubbed by prominent world leaders and clouded by the threat of a US retreat from climate diplomacy after Donald Trump’s victory in the presidential election.

Azerbaijan's COP29 presidency secured an early endorsement of key methodological standards under Article 6 during Monday's opening plenary, driven to action by two years of failure at the annual UN climate summit to move forward on the Paris Agreement's carbon crediting mechanism.

US climate envoy John Podesta acknowledged the election of Donald Trump as “disappointing” for climate action, but remained steadfast in continued private sector and subnational-led efforts to reduce emissions at COP29 on Monday.

Further details from the UN aviation body ICAO on its voluntary credit approvals is unlikely to be published until the end of the month at the earliest, according to Verra’s CEO, making it hard to say when eligible credits are likely to appear and from what countries.
