Scientists surveying the state of the world's periglacial zones, cold regions often home to layers of frozen ground called permafrost, report that the days for many such regions may be numbered. The team now expects climate change to severely reduce periglacial coverage by halfway through the century, no matter what course of action we take in the meantime...

Permafrost is the layer of permanently frozen earth – over a 1,000 metres thick in some places – that lies just beneath the land surface in Arctic regions. It formed over the past few million years when ice ages predominated.
Coastal cities deal with the constant fear that sea levels will continue to rise in coming years due to climate change. In the case of Santos, home of Latin American's biggest harbor, a study supported by the São Paulo Research Foun...
A Florida State University researcher is delving into the complexities of exactly how permafrost thawing in the Earth's most northern regions is cycling back into the atmosphere as carbon dioxide and further fueling climate change.
The decline of cold regions called periglacial zones is now inevitable due to climate change, researchers say.
