The damage wrought to the park’s road by melting permafrost is creating a new reality affecting visitors, park staff, local businesses and potentially wildlife.
The Quebec government has allocated over $2 million to research and develop a plan to adapt public housing in Nunavik to the effects of thawing permafrost, which can cause damage to units built on jacks.
Scientists say that rising global temperatures are causing collapsing mountains as ancient permafrost begins to thaw.
Following a thaw slump, the water becomes cloudy and full of sediment, potentially suffocating the eggs of spawning sheefish. Scientists are concerned that permafrost thaw could lead to declines in the sheefish population, a staple food for many Alaskans.
As Alaskan permafrost warms, hibernating arctic ground squirrels generate less heat, causing females to emerge from hibernation up to 10 days before their male counterparts – a mismatch that could have large, cascading ecological impacts. While reduced thermogenesis due to warming temperatures could allow the squirrels to conserve energy and, thus, increase winter survival, a shortened hibernation season could also increase the exposure of the animals to hungry predators, altering mortality rates, particularly for earlier emerging female squirrels. The phenological mismatch between the sexes may also disrupt reproductive rates. And over longer time scales, continued warming in the Arctic may lead to changes in male squirrel seasonal behaviors, say the authors.
Rare tropical permafrost near Mauna Kea's summit is diminishing, with frozen soil patches showing signs of shrinking over time, according to researchers, who suggest there is no lasting way to prevent it from melting.
