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.
Increased Light Pollution in the Arctic
Satellite data shows rising Arctic nighttime lights, driven by growing industrial activity in oil, gas, and infrastructure.
The Rise of Proglacial Lakes
Glacial retreat in Alaska’s Yakutat Foreland has fueled rapid growth of proglacial lakes, doubling their size in 40 years as seen in Landsat imagery.
Largest Piedmont Glacier in North America
The largest piedmont glacier in North America is found in southeastern Alaska and is known as the Malaspina Glacier.
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.
