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.

Participants in the expedition of the institutes of the Russian Academy of Sciences “Clean Arctic - East - 77” reported the appearance of more southern species of spiders and birds in the Arctic Circle. The unevenness of their appearance at the same geographic latitude showed that the northern border of their ranges did not shift along the entire length, but formed several protrusions in the northern direction in the form of petals. "Petal thawing” referrs to the emergence of zones with a width of 50 to 200 kilometers at the southern base where permafrost is thawing.

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.
