Study reveals weakening of circumglobal teleconnection pattern under future warming and its impact on heat waves
The circumglobal teleconnection pattern (CGT) is a key mode of atmospheric variability during boreal summer, identified by an upper-tropospheric wave train propagating along the subtropical jet. CGT is one of the critical drivers of Northern…

AMOC collapse simulations reveal what could happen to the ocean's carbon
The Atlantic Meridional Overturning Circulation (AMOC) is the system of currents responsible for shuttling warm water northward and colder, denser water to the south. This “conveyor belt” process helps redistribute heat, nutrients, and carbon…

Superheated sediments in a submarine pressure cooker—an unexpected source of deep-sea hydrogen
The mid-ocean ridge runs through the oceans like a suture. Where Earth’s plates move apart, new oceanic crust is continuously formed. This is often accompanied by magmatism and hydrothermal activity. Seawater seeps into the subsurface, is heated…

The Hidden Fire Crisis Building Across the Western U.S.
By stopping fires for generations, the western U.S. may have made its wildfire problem far worse. Wildfires are not always harmful to forests. In many ecosystems, fire helps remove accumulated debris, returns nutrients to the soil, and supports…
