Water on Earth
Earth holds trillions of tons of water, mostly in oceans. Only 2.5% is freshwater, primarily found in glaciers, groundwater, lakes, and rivers.
Defining How Much of the World is Covered by Forests
With no universal definition, mapping and comparing forest coverage around the world is challenging.
Glacial Flour Makes Some Lakes Turquoise
Glacial flour, the fine dust created as glaciers move over land, turns lakes a turquoise color by reflecting blue and green light.
Hydroclimate Whiplash: the Impact on California Wildfires
Hydroclimate whiplash – the rapid swing between drought and heavy precipitation – plays a role in the increasing intensity of California wildfires.
Understanding Glacier Grounding Lines
Grounding lines are the boundaries where glaciers and ice sheets transition from resting on solid ground to floating on seawater.
What are the Earth System’s Four Spheres?
The systems of the earth can be divided into two main areas: geosphere and biosphere.
The Recreational Value of Nature and Wildlife
Measuring the economic benefits of wildlife and outdoor areas supports conservation with tools like the NPS Visitor Spending Effects.
