Leshyk: Thawing of permafrost can cause irreversible tipping points in Arctic landscapes, transforming intact ecosystems (<b>left<\/b>) to severely altered ones (<b>right<\/b>), with impacts on people. A warming climate and fires lead to melting ground ice. Arctic and boreal forests contain permafrost soils with excess ice (more than is contained in soil pores), which form 3D networks in the ground. With warming, this ground ice can melt and the ground surface collapses (<b>A<\/b>). Fires, a natural part of the boreal disturbance cycle, are increasing in extent, frequency, and severity. Melting ice can lead to the accumulation of water in ponds, lakes, and wetlands, but continued thawing can cause lakes to drain. Permafrost can also thaw abruptly, causing thaw slumps and bank failures (<b>B<\/b>). These geomorphological changes impact human infrastructure (<b>C<\/b>) and access to the land (<b>D<\/b>). Other risks (not pictured) include chemical and potentially disease mobilization that can threaten human health and ecosystems. Human adaptation strategies to permafrost thaw include installing firebreaks around infrastructure (<b>E<\/b>).
