Latest Permafrost Stories
Freshwater ecosystems in northern regions are home to significantly more species of water fleas than traditionally thought, adding to evidence that regions with vanishing waters contain unique animal life.
Thawing permafrost will have far-reaching ramifications for populated areas, infrastructure and ecosystems. A geographer from the University of Zurich reveals where it is important to confront the issue based on new permafrost maps -- the most precise global maps around.
Thirty-thousand-year-old bison bones discovered in permafrost at a Canadian goldmine are helping scientists unravel the mystery about how animals adapt to rapid environmental change.
These researchers assert that the Arctic is already suffering some of the effects that, according to The Intergovernmental Panel on Climate Change (IPCC), correspond with a "dangerous climate change". Currently, the rate of climatic warming exceeds the rate of natural adaptation in arctic ecosystems.
What is the lifespan of a natural gas deposit?
According to a survey published in the November 30 issue of the journal Nature, melting permafrost in the northern climes is releasing large amounts of methane and carbon, amplifying the global warming effect.
From the North Pole to the Arctic Ocean, the frozen soils within this region keep an estimated 1,672 billion metric tons of carbon out of the Earth's atmosphere.
Ice and frozen ground at the North and South Poles are affected by climate change induced warming, but the consequences of thawing at each pole differ due to the geography and geology.
Scientists say a tundra fire in the circumpolar arctic released about as much carbon into the atmosphere as the tundra has stored in the previous 50 years.
A much reduced covering of snow, shorter winter season and thawing tundra.
