Embroidery on silk shows the location of arctic permafrost and describes
some of its characteristics.
Many Arctic communities and
infrastructure sit on top of a thick layer of permafrost that has stabilized
the ground for millennia. As global air temperatures rise, this frozen
soil is melting, causing homes and roadways to crumble. Permafrost is
defined as ground that is frozen year-round for a minimum of 2 years.
It is made up of rock, soil, sediments and varying amounts of ice that
bind the elements together. Permafrost covers about 24% of Earth’s
exposed landmass in the northern hemisphere. This embroidery on silk shows
a bird’s eye view of arctic permafrost and describes some of its
characteristics. Darker shades of red indicate larger percentages of permanently
frozen ground. Permafrost thawing also releases carbon dioxide and methane
into the atmosphere, causing even greater atmospheric warming.
