But be it their winter or their summer home, a new study using data from NASA-built Landsat satellites shows that these warblers like to live in young forests […]

Dec 9, 2011Searching for thawing permafrost and at-risk infrastructure

Dec 9, 2011 • Permafrost—ground that remains frozen for at least two years—allows soil substrate to act like bedrock. So when permafrost thaws there can be major problems for structures built atop of it. Imagine if the granite of Mount Rushmore turned to sand… goodbye George, Tom, Teddy, and Abe. Thawing permafrost can pose a […]
