The tundra biome is huge, covering 15% more of the Earth’s surface than all 50 U.S. states combined.

Barren tundra lands, home to hardy flora and fauna, are one of the Earth's coldest, harshest biomes.

The greening of the tundra might seem like a localized impact of a warming planet, but it has far-reaching implications. Our individual actions can help mitigate climate change and slow warming in ...

Tundra is a biome, or ecosystem, where the tree growth is hindered by low temperatures and short growing seasons. It’s the coldest biome, where vegetation isn’t as singular as one might think.

Across the tundra, warming temperatures are causing plants to stay greener longer and flower earlier—and that could reshape life there, according to new research led by the University of Colorado ...

In 2007 the largest recorded tundra fire in the circumpolar arctic released approximately as much carbon into the atmosphere as the tundra has stored in the previous 50 years, say scientists. The ...
