For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October. The delayed annual freeze in the Laptev Sea has been caused by freakishly protracted warmth in northern Russia and the intrusion of Atlantic waters, say climate scientists who warn of possible knock-on effects across the polar region. Ocean temperatures in the area recently climbed to more than 5C above average, following a record breaking heatwave and the unusually early decline of last winter’s sea ice.

As global warming climbs and humanity’s water consumption increases, nuclear and fossil-fueled power plants that rely on freshwater for cooling may not be able to perform at their peak capacity or could be forced to shut down temporarily even as demand for their supplies for indoor cooling and other uses increase, according to researchers and industry experts. Climate change-exacerbated water shortage issues pose a near-term and longer-term performance risk to power plants, such as hydropower and nuclear, around the world. And in the Lower 48, more than half of the fossil-fueled and nuclear fleet is located in areas forecast to face climate-related water stress by the end of this decade under a business-as-usual scenario, according to an analysis by S&P Global Market Intelligence.
