Global sea levels have been underestimated due to poor modelling, research suggests Analysis shows average levels are 30cm higher than thought, and up to 150cm in south-east Asia and Indo-Pacific

It’s worse than we think.

Pedro Sánchez #@sanchezcastejon •5h X The world, Europe, and Spain have faced this critical moment before. In 2003, a few irresponsible leaders dragged us into an illegal war in the Middle East that brought nothing but insecurity and pain. Our response then must be our response now: NO to violations of international law. NO to the illusion that we can solve the world's problems with bombs. NO to repeating the mistakes of the past. NO TO WAR.

The heat suffocates, the fires rage – even by Australian standards, this summer is brutal In this week’s newsletter: The south-east of the country is suffering through the worst heatwave since 2019’s ‘black summer’, while the government continues to back fossil fuel projects

“the govt.,has approved 33 coal & gas developments or extensions since it was elected Just last week, it approved the expansion of a coalmine estimated to release about 236m tonnes of CO2 over its lifetime – equivalent to almost half of Aust’s..annual footprint”

Is panpsychism pseudophilosophy? A response to Walter Veit

Is panpsychism a philosophical dead-end or a legitimate response to the hard problem of consciousness? I respond to Walter Veit's critique and defend panpsychism as a serious metaphysical option, not ornamental fluff. #philsky @walterveit.bsky.social

Australia’s record heatwave as seen from space🌡️ Thermal data acquired by the @copernicus_eu Sentinel‑3 Sea and Land Surface Temperature Radiometer highlight the severity of the ongoing heatwave across Australia, with extreme land surface temperatures (LST) detected over large regions. For example, in Willcania and Broken Hill, recorded land surface temperatures ranged between 58 and 60 °C, whereas Adelaide appeared cooler, with temperatures of 45–48 °C, likely due to its proximity to the sea. Land surface temperature represents the physical temperature of the Earth’s surface — essentially, the temperature you would measure if you touched the ground. This differs from air temperature, typically reported in weather forecasts, which is measured a few metres above the surface and is usually cooler. Sentinel‑3’s SLSTR instrument retrieves these surface temperatures by measuring thermal infrared radiation emitted by the surface, allowing scientists to monitor heat extremes, drought stress, and conditions conducive to bushfires with high spatial and temporal accuracy. Observations like these provide crucial insights into how rapidly heatwaves intensify and how they affect ecosystems, fire risk, and communities on the ground.
