Assessing a New Clue to How Much Carbon Plants Take Up
Current climate models disagree on how much carbon dioxide land ecosystems take up for photosynthesis. Tracking the stronger carbonyl sulfide signal could help.
New Tool for Understanding Landscape Evolution in Drylands
Combining vegetation distribution models and sediment transport models offers a better understanding of how dryland environments change in response to different factors.
Tracking Global Change with a Cloud-Based Living Atlas
With their feet in the cloud, Descartes Labs is pushing the limit of how we study the Earth with satellite images.
How Do Trees Respond to Climate Change? Clues from an Arboretum
The rich diversity of trees at arboreta may allow scientists to home in on the specific traits that allow trees to grow faster or slower in response to warming temperatures.
Groundwater: A Hidden Influence on River Shape
A new study shows how groundwater influences river dynamics and channel pattern.
Air Pollutant Plays Lesser Role in Climate Change Than Expected
Satellite data indicate that pollution control efforts that curbed levels of sulfur dioxide gas did not cause a major decrease in carbon dioxide absorption by plants.
Switching to Drought-Tolerant Plants Could Alter Urban Climates
In Los Angeles, replacing lawns with native plants that need less water could lead to hotter days and cooler nights.
Aquatic Plants May Accelerate Arctic Methane Emissions
About two thirds of the gas produced by a study area near Barrow, Alaska, came from increasingly abundant greenery covering only 5% of the landscape, researchers estimate.
Nitrogen Garners Starring Role in Refined Earth System Model
Scientists create a more realistic representation of plant nitrogen uptake and usage to improve global climate simulations.
