Sea surface temperatures have touched 30 degrees Celsius for the first time, raising alarm over a possible severe El Nino event. Bengali media warn of a major disaster with effects expected in India, while reports point to a huge Kelvin wave heading toward the California coast, seen as a hidden signal of climate disruption beneath the ocean.

Researchers report the observation of Kelvin waves — helical distortions that ripple along quantized vortices just nanometers wide in quantum fluids. The waves have long been proposed as a mechanism for how turbulence dissipates in superfluids, and confirming them directly closes a decades-old question in quantum turbulence research.
