Climate change is warming the Arctic tundra about four times faster than the rest of the planet. Now, a study suggests that rising temperatures will spur underground microbes there to produce more ...

The fragile Arctic tundra is undergoing a dramatic transformation, according to a University of Gothenburg study. The international research shows that plants from nearby forests are steadily ...

A new international study involving researchers from the University of Gothenburg shows that vegetation in the Arctic is changing rapidly as species from nearby forests spread into the tundra. This ...

COAT's weather stations, even those located far beyond today's forest distribution on the Varanger Peninsula (green areas on the map), have experienced temperatures above the 10-degree threshold ...

The Arctic tundra, a critical “carbon sink” for thousands of years, is now releasing more of the greenhouse gas than it takes in, scientists have announced. Carbon sinks like the Arctic play crucial ...

A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the islands. In the frigid seas halfway ...

Ecologist Isla Myers-Smith researches how tundra plants respond to climate change and what it means for future ecosystems. While she's mostly worked in the Canadian Arctic, for the last two years ...

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 ...

Arctic and boreal latitudes are warming faster than any other region on Earth. Arctic and boreal latitudes are warming faster than any other region on Earth. In three new studies, Earth system ...

New research provides the latest evidence that climate change is having an impact on food webs in high-latitude ecosystems. Biologist Amanda Koltz of The University of Texas at Austin in the Alaskan ...

When UC Santa Barbara doctoral student Seeta Sistla and her adviser, environmental studies professor Josh Schimel, went north not long ago to study how long-term warming in the Arctic affects carbon ...
