Latest Tundra Stories
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.
Greenhouse gas emissions from previously frozen organic carbon in soil are seen as larger than previously believed.
By Carrie Peyton Dahlberg TOOLIK FIELD STATION, Alaska - Beyond the Arctic Circle, teams of scientists measure widening slumps as ice melts beneath the tundra. They scuff through tussocks blackened by unexpected fires, and search for fish in drought-depleted streams.
U.S.-led scientists say they have found the last traces of tundra that grew in interior Antarctica before temperatures dropped millions of years ago.
TOOLIK LAKE, Alaska _ Ground here that for tens of thousands of years was frozen solid is terra firma no more. Across the tundra and coast of the Arctic Ocean, land is caving in.
Global air and water temperatures are inching up, causing seas to warm and expand, and polar ice to melt.
By Carrie Peyton Dahlberg, The Sacramento Bee, Calif. Jul. 18--TOOLIK FIELD STATION, Alaska -- Beyond the Arctic Circle, teams of scientists measure widening slumps as ice melts beneath the tundra.
DIMPLE LAKE, Alaska _ The Arctic is burning. It long has, of course, but now with greater regularity and more ferocity. Splinters of lightning crackle on the tundra, setting ablaze runaway fires that toast the landscape black.
The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR).
The Arctic is under increasing stress from warming temperatures as shrubs colonize the tundra, changing wildlife habitat and local climate conditions, researchers said Wednesday.
Taiga, or otherwise known as boreal forest, is a biome that is characterized by coniferous forests made up mostly of spruces, larches, and pines. The taiga is the world’s largest terrestrial biome. In North America, it covers most of inland Canada and Alaska as well as portions of the extreme northern continental United States and is known as the Northwoods. It covers most of Sweden, Finland, much of Norway, lowland/coastal areas of Iceland, much of Russia, northern Kazakhstan, northern...
Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...
Reindeer moss is a moss belonging to the family Cladoniaceae. It grows in both temperate and cold climate areas. It has had great economical importance, since it is the main fodder for reindeers. It can also be used in the making of aquavit and is sometimes used as decoration in glass windows. Reindeer moss is actually another name for reindeer lichen. This lichen is found in the Alpine tundra and can survive in the cold. Image Caption: Reindeer Moss photographed in White Oak Mountain,...
