Latest Tundra Stories
Scientists at the Department of Energy's Oak Ridge National Laboratory are planning a large-scale, long-term ecosystem experiment to test the effects of global warming on the icy layers of arctic permafrost.
Vegetation around the world is on the move, and climate change is the culprit.
Contrary to scientists' predictions that, as the Earth warms, the movement of trees into the Arctic will have only a local warming effect, University of California, Berkeley, scientists modeling this scenario have found that replacing tundra with trees will melt sea ice and greatly enhance warming over the entire Arctic region.
The increase in temperature in the Arctic has already caused the sea-ice there to melt.
Much of circumpolar Arctic research focuses on the physical, direct changes resulting from climate warming such as sea ice retreat and temperature increases.
The terrain of the North Slope of Alaska is not steep, but Andrew Jacobson still has difficulty as he hikes along the spongy tundra, which is riddled with rocks and masks multitudes of mosquitoes.
"I wonder if I shall fall right through the Earth!" mused Alice-in-Wonderland as she tumbled down the rabbit-hole." How funny it'll seem to come out among people that walk with their heads downwards!
As frozen arctic soil thaws due to climate change, U.S.
Ancestors of tapirs and ancient cousins of rhinos living above the Arctic Circle 53 million years ago endured six months of darkness each year in a far milder climate than today that featured lush, swampy forests.
â€œA slow-motion time bomb.â€ Thatâ€™s what one ecologist calls the looming threat of trapped greenhouse gases in the melting Arctic.
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,...
