Instead of an existential crisis for species worldwide, or threatening to submerge entire Pacific nations and coastal cities where hundreds of millions of people live, or a phenomenon driving unprecedented heatwaves and wildfires, the climate crisis was characterised somewhat differently on major US cable show Real Time with Bill Maher.

Oceanographer Stefan Rahmstorf explains why Amoc breakdown could be catastrophic for both humans and marine life

The dangers of a collapse of the main Atlantic Ocean circulation, known as Amoc, have been “greatly underestimated” and would have devastating and irreversible impacts, according to an open letter released at the weekend by 44 experts from 15 countries. One of the signatories, Stefan Rahmstorf, an oceanographer and climatologist who heads the Earth system analysis department at the Potsdam Institute for Climate Impact Research in Germany, explains here why he has recently upgraded his risk assessment of an Amoc breakdown as a result of global heating – and what that means for Britain, Europe and the wider world.

Long-delayed regulations may ‘encourage’ housebuilders to equip homes with solar panels, rather than requiring them

Labour is considering making solar panels optional on new homes in England, after pressure from housebuilders, in a move that would weaken low-carbon regulations, the Guardian has learned.

Exclusive: Those with ‘interest in keeping world hooked on fossil fuels’ should not oversee climate talks, say report authors

Azerbaijan, the host of the Cop29 global climate summit, will see a large expansion of fossil gas production in the next decade, a new report has revealed.

Azerbaijan’s state-owned oil and gas company, Socar, and its partners are set to raise the country’s annual gas production from 37bn cubic metres (bcm) today to 49bcm by 2033. Socar also recently agreed to increase gas exports to the European Union by 17% by 2026.
