Writing for Science Alert, Carla Cassella (@carlycassella) highlights chaotic new patterns in jet streams, the currents of air that wrap around the planet. The currents are splitting at such an extreme rate that the experts Cassella quotes used words like “insane” to describe the large-scale patterns now visible across the globe, which are causing extreme heat, die-offs of bird and marine life, unusually wet weather, and early hurricane seasons. Science points to the combination of global warming and El Niño as the likely culprit. Image: NOAA (public domain)
