Global effort needed to limit effects of pollution, industrial fishing and climate crisis, World Ocean Assessment says

In the icy waters of the Southern Ocean, whales and other marine mammals rely on krill to survive. But as the market for human dietary supplements and animal feeds booms, and climate change reduces krill populations, scientists worry there may not be enough to go around.

Halting and reversing the global decline in biodiversity is now urgent to avoid destabilizing Earth's vital systems that support human well-being. That's the stark message of a new paper published today in Frontiers in Science. The authors warn that without protecting remaining intact biomes and ecosystems, climate and development goals will be impossible to achieve.

You may have heard the rumors of a "monster El Niño." It's not the first time we've heard forecasts like this in Australia, but this time, they aren't coming out of nowhere. Early signs in the Pacific have been building for months and forecasts now point to a high likelihood of a moderate to strong El Niño developing in 2026.

Weather models project a potentially strong El Niño this year, which could spell disaster for heatwave-hit India, drench China and hurt agriculture across south-east Asia

La construction d'un datacenter en Utah a entrainé une opposition farouche des habitants. La course à l'IA repose la question de l'équilibre entre technologie et ressources limitées en eau, en terres arables et terres rares, en électricité. De nombreux datacenter vont utiliser des énergies fossiles.

Exxon warns oil inventories will hit dangerously low levels in weeks, forcing prices to shoot higher. […]

Brutal El Nino, drought, war threatens food supply

Scientists have uncovered alarming new evidence that a common insecticide may leave lasting marks on the developing brain before a child is even born. Researchers studying New York City children found that prenatal exposure to chlorpyrifos — a pesticide once widely used indoors and still used in agriculture — was linked to widespread brain abnormalities and weaker motor skills years later.

How Cynicism Became the New Psychological Performance

Modi denied climate change for years. Now, as heat deaths mount, his government offers branding instead of protection.

World is approaching point where no one can shut down a rogue AI, says director of body behind research

A five-year study found that warming oceans are causing Maine’s underwater kelp forests to disappear and be replaced by turf algae.

Climate and geopolitical shocks – from El Niño, global heating or wars – hit a food system which already magnifies environmental and social vulnerabilities.

Current energy projections often envision an expansion of nuclear capacities to decarbonize future energy systems. However, this contrasts with the historic and current status of the nuclear industry, marked by techno-economic challenges for both light-water and non-light-water reactor technologies. Regardless, projections of strong nuclear growth have persisted since the 1970s. This paper investigates the “nuclear energy paradox” which shows the recurring divergence between historical projections and actual developments. A data compilation of long-term energy projections from international organizations such as the IAEA and the IEA as well as energy system models like GCAM and MESSAGE, as used in the IPCC, reveal a recurring pattern of high-growth projections for nuclear power. Such projections often rest on techno-economic assumptions such as substantial cost reductions. We propose the concept of nuclear imaginaries to show that these assumptions are embedded into techno-economic visions of nuclear power de
