Between 2000 and 2020, 42% of tree lines around the world crept upward, largely because of climate change. But 25% moved downhill, seemingly because of factors such as land use changes and wildfires.

2026 Has Already Broken Climate Records. El Niño Could Break More.
As the midpoint of the year approaches, several climate records have already been broken. Arctic winter sea ice extent reached a record low. Several countries saw record-breaking winter heat waves. And more than 150 million acres have already burned globally in wildfires.
Most of the U.S. West Will Face Above-Normal Wildfire Risk This Summer
The National Interagency Fire Center predicts elevated wildfire potential across much of the West and many Southeast states through August.
Sensing the Sounds from Earth’s Hazardous Environments
Low-cost infrasound sensors, deployed in large numbers, provide a practical means of data collection near volcanoes, earthquakes, wildfires, and other geophysical phenomena.
Want to Predict Wildfire Severity? Look to the State of Vegetation
A new study connects satellite data on vegetation condition, topography, and weather conditions to examine the predicted versus actual burn severity of the 2025 Los Angeles wildfires.
How Wildfires Worsen Flood Risk
A new approach to analyzing watersheds shows how storms occurring after a wildfire can have higher flooding risk than similar storms that occurred before a fire.
Weather Radar Data Reveal the Dynamics of Rapidly Spreading Wildfires
New research demonstrates the use of operational weather radar measurements to track long-range ember fallout and rapid spread of intense wildfires.
Alaska’s Wildfires Heat the Planet, but Canada’s Cool It
Using 2 decades of satellite data, researchers learned that wildfires in North America don’t follow the same script: In western Canada, snow reflectivity drives a cooling effect, whereas in Alaska, permafrost burning leads to net warming.
An Art-Science Partnership Offering New Views of Dynamic Landscapes
The immersive and interactive WILDLAND exhibition allowed the public—and the exhibition’s creators—to explore connections among water, trees, fire, and other natural and human-made materials expressed across a spectrum of artistic approaches.
Senate Committee Approves Bill to Expand NOAA Capabilities
The markup meeting, to discuss the NASA Transition Authorization Act of 2026 and the Weather Research and Forecasting Innovation Reauthorization Act of 2026, lasted less than 20 minutes.
