The Amazon Rain Forest Can’t Keep Up with Droughts
Droughts in one region of the Amazon can lead to less moisture elsewhere, and trees may not adapt quickly enough to survive.
Tropical Wetlands Emit More Methane Than Previously Thought
Climate models could be vastly underestimating methane emissions from the world’s tropical wetlands, according to observational surveys of wetlands in Zambia.
Supervolcanoes Linger a While, Then Rush to Erupt
Geologists examined crystals in rock from four massive eruptions in the Chilean Andes.
Alaskan Glaciers Advance and Retreat in Satellite Imagery
Researchers tracked 19 maritime glaciers in Kenai Fjords National Park over several decades and found that tidewater glaciers tended to experience less ice loss than other types of glaciers.
New Map of Proposed Mantle-Driven Topography Stirs the Pot
The role the deep Earth plays in creating topography is hotly debated. A new study uses subtle elevation changes around the globe as evidence that the mantle plays a key role in building topography.
Models Oversimplify How Melting Glaciers Deform Land
When glaciers melt, the land below deforms. Sea level data show that widely used models oversimplify the process.
Gigantic Jet of Lightning Mapped over Oklahoma
The most powerful gigantic jet ever recorded fortuitously appeared over a sensor array in Oklahoma, enabling scientists to map the structure of the phenomenon for the first time.
From SAR Arc to STEVE: An Atmospheric Evolution
A new study reports the first observation of a stable auroral red arc evolving into a strong thermal emission velocity enhancement during a geomagnetic storm.
Chasing Fire Tornadoes for Science
Recent research suggests fire-generated vortices are always present during wildfires.
