题目 Climate change is warming the Arctic tundra (冻原) about four times faster than the rest of the planet. Now, a study suggests that rising temperatures will boost underground microbes (微生物) there to produce more carbon dioxide (CO_{2})——potentially creating a feedback loop that wors...

The Arctic is highly sensitive to climate change, and the rise in its near-surface air temperatures has been almost twice the global average. The increased growth of the Arctic tundra and its changing seasonality have been observed, largely in response to the impacts of climate change. In this...

Arctic terns can be found just about everywhere as their travelstake them toevery ocean and every continent. They breed on the coasts and tundra of Arctic and subarctic regions of Europe, Asia, and North America, then follow the sun and fair weather on their yearly journey to the Antarctic ...
Svalbard tundravegetation productionClimate change is most pronounced at high latitudes, where plant and animal populations are often strongly influenced by environmental fluctuations related to climate and weather. Environmental conditions can co‐fluctuate over large distances and thereby synchronise primary ...
