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. The ...

The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon ...

The boreal forest, covering much of Canada and Alaska, and the treeless shrublands to the north of the forest region, may be among the worst impacted by climate change over the next 500 years, ...

WASHINGTON—The icy region at the top of the globe, lashed by wildfire and pelted with increasingly heavy precipitation, has tipped into “uncharted territory,” scientists reported Tuesday. The Arctic ...

Arctic tundra, which has stored carbon for thousands of years, has now become a source of planet-warming pollution. As wildfires increase and hotter temperatures melt long-frozen ground, the region is ...

Foreboding environmental milestones abounded again this year in the Arctic, where experts say dramatic climate shifts are fundamentally altering the ecosystem and how it operates. One recent turning ...

Climate change is warming the Arctic tundra about four times faster than the rest of the planet. Now, a study suggests that rising temperatures will spur underground microbes there to produce more ...

The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs. From beaver ...
