A new machine-learning technique reportedly doubles AI weather-forecast skill two to six weeks ahead, improving warnings for extreme events and planning.
There is a growing movement—primarily among climate activists and some commentators—to name storms, especially hurricanes and other climate-related disasters, after major fossil fuel companies. The idea is to highlight the role these corporations have played in contributing to climate change, which is linked to more frequent and intense extreme weather events.
In a recently published paper, NASA scientists use nearly 20 years of observations to show that the global water cycle is changing in unprecedented ways. Most of these changes are driven by activities such as agriculture and could impact ecosystems and water management, particularly in certain regions.
