Melting permafrost causing tundra to slip below sea level in northern Alaska.
We performed a survey of community water lines to see how permafrost thaw and sinking foundations may be impacting homes, water and waste water systems. During the June visit we saw where foundation sinking was putting stress on pipe runs and junctions. Now in the winter we see evidence of freeze up in some of the homes where the junction boxes have been compromised, gaps in the insulation seal, and resulting freeze up and overflow of water.
Arctic food storage system at risk.
"Roads are actually getting worse in the springtime than they were even [a few] years ago. In a perfect world, we'd be able to re-engineer all of our roads and get them paved. It's going to be a long-term process to get there." say Deputy Mayor Kyle Sheppard.
In northern Alaska, an amphitheater of frozen ground thaws where a northern river cuts into it, exposing walls of ice. The feature, known by scientists as “yedoma,” is the largest of its kind yet found in Alaska. A great wall of ice holds a lot of treasures from the past, which science is eager to explore.
A historic site in Yoho National Park will be dismantled and removed this spring because of effects caused by climate change, Parks Canada announced Thursday.
The slope of permafrost where an 810-foot section of pipeline is secured has started to shift as it thaws, causing several of the braces holding up the pipeline to tilt and bend, according to an analysis by the Alaska Department of Natural Resources.
A permafrost scientist in the N.W.T. is leading an experiment that compacts snow near the Inuvik-Tuktoyaktuk Highway to see if that will slow down permafrost thaw and protect buildings and roads built atop it.
The issue of erosion is not new to Noatak cemetery. The old cemetery was located near the Noatak's airstrip, but in 1993, the spring breakup caused 30 feet of erosion adjacent to the cemetery. Flooding during the fall of 1994 further threatened the site, so residents relocated 200 graves to the north side of town.
