Warming global climate is changing the vegetation structure of forests in the far north. It's a trend that will continue at least through the end of this century, according to NASA researchers.

We identify biomes by the vegetation and animals that populate them and determine the location of each by the regional climate. The tundra biome is characterized by extremely cold temperatures and ...

Mountain goats, sheep, marmots, and birds live in mountain—or alpine—tundra and feed on the low-lying plants and insects. Hardy flora like cushion plants survive in the mountain zones by ...

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 ...

Now scientists can add the Arctic tundra to that list. In most ecosystems, plants absorb carbon dioxide from the atmosphere. Those plants grow, die, or get eaten by animals that also grow and die.
