As the name suggests the permafrost is permanently frozen, summer and winter. The surface may have some liquid water, but the deeper layers are cold enough not to thaw.
This situation is changing as global climate change progresses. The permafrost will disappear leaving vast tracts of boggy land that are not capable of walking on (bad news for the communities and migrating herds of caribou). In addition the melting permafrost will release vast quantities of methane gas which will make climate change even more severe.

In Arctic regions the summer warmth fails to warm the permafrost.
What happens to grass in the winter if it is not mowed in the summer?

How and why is melting of permafrost dangerous?
Permafrost, when it melts, releases vast amounts of methane (CH4), a powerful greenhouse gas, produced from the anaerobic rotting of the permafrost vegetation. This increases global warming, which is causing climate change.
Why does permafrost remains throughout the summer?
Groundcover Vegetation
What is permafrost on Mars?
Permafrost is the frozen liquid or gases on Mars, that never melt. While Mars' polar ice caps do shrink and grow, there are portions of it that never melt. This is the permafrost. It is frost that never melts (ie permanent frost).
Permafrost thaws only briefly in the summer?
hell naww
How can permafrost cause architectural damage?
When the permafrost melts it can leave some pieces behind and freeze so hard around something that it can cause damage for being so cold and hard!!!
What is permafrost?
Permafrost is permanently frozen soil, a common feature of Polar regions. There is an "active layer" at the surface of varying depth which does melt during the summer when the temperature consistently warms above freezing. Permafrost is often rich in organic matter due to the slow rate at which it decomposes in these climates. It also causes problems for humans who try to build on it, who find that the ground that supports their structures can shift dramatically underneath them as the permafrost melts due to the heat generated by the buildings as well as the warming Arctic.
