Foreboding environmental milestones abounded again this year in the Arctic, where experts say dramatic climate shifts are fundamentally altering the ecosystem and how it operates. One recent turning ...

As Arctic summers warm, Earth's northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a team of researchers finds the region has become greener as ...

"The Arctic tundra is one of the coldest biomes on Earth, and it's also one of the most rapidly warming," said Logan Berner, a global change ecologist with Northern Arizona University in Flagstaff, ...

The Arctic tundra is warming up and that's causing long-frozen ground to melt as well as an increase in wildfires. The region is "now emitting more carbon that it stores, which will worsen climate ...

A muskox stands amid Greenland's arctic tundra. Large herbivores have been found to play a critical role in maintaining tundra biodiversity. (Eric Post/UC Davis) Being common is rather unusual. It’s ...

Warming temperatures are causing plants across alpine and arctic environments to stay green longer and reproduce earlier, scientists find Across the tundra, warming temperatures are causing plants to ...

Arctic summers are becoming warmer, and the result is a greener Arctic landscape. NASA has been using satellites to track global tundra ecosystems for decades. A new study found that the Arctic region ...

Climate warming reduces the number of plant species in the tundra, but plant-eating animals, such as reindeer and voles, can turn this negative effect into something positive. The results of a study ...

Sept. 23 (UPI) --New data, collected and analyzed by scientists with NASA and the U.S. Geological Survey, suggests rising air and soil temperatures are accelerating plant growth across tundra ...

The response of tundra plants to enhanced UV-B radiation simulating 15 and 30% ozone depletion was studied at two high arctic sites (Isdammen and Adventdalen, 78° N, Svalbard). The set-up of the UV-B ...

As Arctic summers warm, Earth's northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air ...
