Oceans losing climate-calming powersThe world’s oceans have long helped to stave off climate change by absorbing heat and carbon dioxide from the atmosphere. But that is changing, warn leading researchers in a high-level report from the Intergovernmental Panel on Climate Change (IPCC). The oceans “can’t keep up” with humanity’s greenhouse-gas output, says Ko Barrett, vice-chair of the IPCC and a deputy administrator at the US National Oceanic and Atmospheric Administration. “The consequences for nature and humanity are sweeping and severe.”

Japan’s stem-cell free-for-allClinics flogging unproven cell-based therapies are springing up all over the world.
