The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon ...

BISMARCK — As the state of North Dakota trumpets Project Tundra, experts outside of the state raise questions about capturing carbon dioxide emissions from two units at coal-fired Milton R. Young ...

Chunks of carbon-rich frozen soil, or permafrost, undergird much of the Arctic tundra. This perpetually frozen layer sequesters carbon from the atmosphere, sometimes storing it for tens of thousands ...

Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be ...

In the next 100 years, Alaska will experience a massive loss of its historic tundra, as global warming allows these vast regions of cold, dry, lands to support forests and other vegetation that will ...

Tundra plants can eek out an existence in the very short summers of the Canadian High Arctic such as here on Ellesmere Island, Nunavut. (Anne Bjorkman, University of Gothenburg) Rapid climate change ...

After locking carbon dioxide in its frozen soil for millennia, the Arctic tundra is undergoing a dramatic transformation, driven by frequent wildfires that are turning it into a net source of carbon ...

ANCHORAGE, Alaska (Reuters) - A wildfire that burned over 400 square miles of Alaska tundra in the scorching summer of 2007 poured as much carbon into the atmosphere as the entire Arctic normally ...

Climate warming can induce the encroachment of shrubs and may trigger treeline dynamics. However, the responses of shrubs and trees to climate change may be modulated by other environmental drivers ...

"Previously people had thought that the tundra might be colonised by trees from the boreal forest to the south as the Arctic climate warms, a process that would take centuries. But what we've found is ...
