New research published in Science argues that a mega El Niño, with extreme and prolonged climate swings, triggered the end-Permian mass extinction around 252 million years ago, the deadliest extinction event in Earth's history. The study suggests these wild temperature and rainfall fluctuations stressed ecosystems beyond their ability to adapt, offering a new explanation for why the tropics and higher latitudes were hit so hard.

An unmanned, hurricane-proof Saildrone vessel has begun a treacherous 22,000km journey around Antarctica, departing from Hobart in the name of climate science. The autonomous craft is designed to withstand extreme conditions while collecting ocean and climate data from one of the planet's harshest marine environments, drawing attention for the ambition of its circumnavigation.

Some television meteorologists are increasingly working climate change into their weather forecasts, linking daily conditions to longer-term warming trends. The effort, reported by CBC, has met resistance from parts of the audience who would rather forecasters stick to short-term weather. The debate highlights tensions over how broadcasters should communicate climate science to the public.

The Guardian reports that scientists employed by Saudi Arabia, including staff tied to state oil company Aramco, ended up working on major IPCC climate reports, the world's most influential assessments of climate science. The revelation has drawn attention to how fossil fuel producing states shape global climate science and policy through their participation in these UN-backed processes.
