High voltage required to use Aemo’s emergency backstop is a bit like stopping a car by driving into a tree, Vince Garrone says Get our breaking news email, free app or daily news podcast This week’s call by the Australian Energy Market Operator for “emergency backstop” mechanisms to switch off rooftop solar systems brings safety risks, because the high voltages needed exceed the limits that many appliances have safely been tested for. That’s according to Vince Garrone, former power quality manager at Energex, Queensland’s biggest electricity distributor who called the situation ironic. Authorities, in using “brute force” to trip inverters, were creating the very high voltage conditions the device protection was designed to prevent.

Campaigners want rethink of national policy because of ‘wasteful knock-it-down-and-start-again approach’ Campaigners are calling for planning rules to consider the environmental implications of knocking down buildings after a controversial redevelopment of Marks & Spencer’s historic store on London’s Oxford Street was given the green light by the government. Save Britain’s Heritage said national policy should consider the embedded carbon linked to a site when considering its future and prioritise reuse of historic buildings amid the climate crisis alongside issues such as preserving important architecture.

Hunting bigger, more experienced animals eradicates memories and knowledge crucial to group survival, research suggests It’s not just humans who get wiser as they age – animals do too, according to a growing body of research. The bigmouth buffalo fish can reach 127 years old, the Greenland shark 392, and some sponges can live for 10,000 years or more. And age is not just a number: as animals get older they behave differently depending on their life experiences, gain richer knowledge of their environment, and often pass it on to younger members of their group, researchers say. The problem is, we are killing off these older creatures. “Earth’s old animals are in decline,” researchers warned in a paper published in Science last month, which analysed more than 9,000 peer-reviewed papers. Few animals make it to old age, and the ones that do are vulnerable to being hunted or harvested by humans, because they are the biggest or have, for example, the largest antlers, horns or tusks.

The overwhelming majority of Europeans support climate action, but they must be compensated for its costs in tangible ways This year was not an easy time to be Green. Green parties took a beating in June’s European elections, with their seat count plummeting from 71 to 53. In national elections they haven’t fared much better. The Green party was nearly wiped out in last week’s general election in Ireland, losing all but one of its seats after having been part of a coalition government. At the same time, climate-sceptic parties framing environmental policies as elitist and unfair have surged across the continent. In Germany, for instance, the far-right AfD owes some of its electoral success to its rallying cry against an emerging “eco-dictatorship”. Björn Bremer is an assistant professor of political science at Central European University and a John F Kennedy Memorial fellow at Harvard University. Jane Gingrich is a professor of social policy at the University of Oxford. Hanna Schwander is a professor of political sociology and social policy at the Humboldt University of Berlin. They are all co-conveners of the Progressive Politics Research Network, whose findings are published here Continue reading...

‘Tight correlation’ between premium rises and counties deemed most at risk from climate crisis, experts say Concern over the climate crisis may evaporate in the White House from January, but its financial costs are now starkly apparent to Americans in the form of soaring home insurance premiums – with those in the riskiest areas for floods, storms and wildfires suffering the steepest rises of all. A mounting toll of severe hurricanes, floods, fires and other extreme events has caused average premiums to leap since 2020, with parts of the US most prone to disasters bearing the brunt. A climate crisis is starting to stir an insurance crisis. Continue reading...

New liquefied natural gas projects could produce 10 gigatonnes of emissions by the end of the decade, close to the annual emissions of all coal plants A $200bn wave of new gas projects could lead to a “climate bomb” equivalent to releasing the annual emissions of all the world’s operating coal power plants, according to a report. Large banks have invested $213bn into plans to build terminals that export and import gas that is chilled and shipped on ocean tankers. But a report has warned that they could be more damaging than coal power. Continue reading...
