This is the biggest permafrost crater in the world, at over 3,200 feet long and 300 feet deep. Professor, Department of Botany, University of Washington, Seattle, Washington. Cold and Dry Climate: That means not only is the planet less capable of preventing greenhouse gases from accumulating, but the tundra is also contributing to their buildup. They are highly vulnerable to environmental stresses like reduced snow cover and warmer temperatures brought on by global warming.

This map shows the major regions where tundras are most common; tundras are in yellow. Trips to the North Pole leave from a number of countries, including Russia and Canada.

In the tundra the fall and spring seasons are basically non-existent, leaving only two seasons—winter and summer.

These plants are food for animals like arctic hares and squirrels, caribou, lemmings and voles; eating these animals in turn are arctic foxes, wolves, and polar bears.

For example, marmots are found in the Carpathians, Apennines, and Pyrenees in Eurasia, in the Deosai Plateau of Ladakh in India, and also in the Rockies, Sierra Nevada, and other mountains of North America. Because nearly all of Antarctica is covered with ice, it lacks a well-developed tundra, though lichens, mosses, and at least three species of flowering plants occur in more favourable habitats there. Did Yellowstone wolves really save the park’s ecosystem? Unfortunately, the arctic tundra is shrinking as a result of climate change; the increasing temperatures are causing the permafrost to melt.

It can’t even be penetrated by water, which is why the soil above permafrost gets very soggy in summertime, when bogs, lakes, and marshes lie on the land. Marina Leibman, from the Earth Cryosphere Institute, part of the Russian Academy of Sciences, told the website the formation was a "thermocirque"—a slump that forms through the thawing of ice-rich permafrost. Hardy flora like cushion plants survive in the mountain zones by growing in rock depressions, where it is warmer and they are sheltered from the wind.
