“A tiny mountainous region in southern Siberia may have been the genetic source of the earliest Native Americans, according to new research by a University of Pennsylvania-led team of anthropologists.” Quoted from the NSF press release.
“Fountain Stream is one of the largest rivers draining Malaspina Glacier. The changes in this river over the past 120 years provides an example of how glacial retreat can starve rivers of sediment and lead to erosion downstream, and an example of the complex changes that can result from climate change.”
” The storm we watched eroded 10 feet of forest floor. Beneath the tree roots, we could see the remains of beaches formed only a few decades ago, when a surplus of sand was still flowing from the glacier.” Quoted from the case study.
After a storm, the signs of rapid coastal erosion are especially obvious. Here, spruce roots trail uselessly down to the beach, where the dirt has been washed away beneath them. Coastal Erosion Slideshow

“As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous estimates. This thawing will release approximately the same amount of carbon as deforestation. However, the effect of thawing permafrost on climate will be 2.5 times greater because emissions include methane.” Quoted from the University of Alaska Fairbanks press release.
