Changes already observed in Alaskan landscapes include rapidly eroding shorelines, melting ground ice (permafrost), wetland drying, ice wedge degradation, increased shrub growth at high latitudes, and conifer forest decline [2 4].

Collapsing Into Melting Ground will be the story for far more infrastructures in the far north, as permafrost melts.
Robin Winters: Trial by Fire (From the Melting Ground) Beacon Project Space, 240 Main Street, through April 26.
The thawing of permafrost creates thermokarst topography, an uneven surface that contains mounds, sinkholes, tunnels, caverns, and steep-walled ravines caused by melting of ground ice.
They might be the remnants of a hail of space stones that pelted the planet about 13,000 years ago, bursting in midair and melting the ground like miniature nuclear warheads.
Those joining the future Massive mainstays included Tricky, Mushroom and Nellee Hooper – collectively, the Wild Bunch, whose 1982-86 Wednesessionssions were the melting pot/testing ground for what followed.
In the catchment, the thawing of permafrost and melting of ground ice creates thermokarst and causes altered lake chemistry and massive landslides into lakes.
Even building houses is a challenge, as the pressure of a large structure melts the ground and causes it to sink, forcing engineers to use a device called a thermosyphon to keep the ground frozen year-round.
Whereas anyone could attempt to dig prospect holes, a realistic mining operation required $1,500 ($41,000) for wood to be burned to melt the ground, along with around $1,000 $27,0000) to construct a dam, $1,500 $41,0000) for ditches and up to $600 $16,0000) for sluice boxes, a total of $4,600 $125,0000).
"So it's a soft surface, and sometimes you just feel like you're just melting into the ground.
