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.
The American Policy Center (APC) say this because they are global warming skeptics. They believe that global warming is not happening.
The first is world-wide changes in climate caused by global warming. The second is a frozen layer of ground.
It is not so much that permafrost is good, as losing permafrost is bad. Permafrost keeps gases like carbon dioxide trapped within its frozen depths; when permafrost thaws, that gas is released, exacerbating global warming. Further, permafrost develops its own ecosystem which is destroyed when the permafrost is destroyed through thawing. The loss of all permafrost would mean the extinction of a lot of species.
Scientists have been using the data over the last 250 years (since the start of the Industrial Revolution) to monitor the rise of Global Warming.
All (current) global warming is the result of an increased abundance of heat trapping gas. As the arctic regions warm, methane gas trapped in permafrost soil is being released, accelerating the global warming effect.

Global warming continues to occur, as evidenced by the fact our polar ice caps are melting, and of course by global temperature records.
If global warming continues, not that long from now.

potentially all vegatable matter currently locked in permafrost may begin to decompose and release huge amounts of greenhouse gasses into the atmosphere.
The weather continues to worsen because of global warming. Global warming affects the atmosphere and is caused by various elements such as pollution. Pollution goes out into the atmosphere and causes negative effects on the climate.

Global warming has caused the permafrost to melt letting coastlines and inlets to recede into the land slowly flooding villages.
Coastal Areas and Islands, atolls.
If global warming continues, scientists predict that weather events like storms, floods and droughts will become more severe and more common. Ice caps and glaciers will melt causing sea levels to rise. This will affect low lying countries, especially in the Pacific Islands.
