If snow conditions are good, lemmings prosper and can even get a head start in raising young. Without urgent action to cut greenhouse gas emissions, the world will continue to feel the effects of a warming Arctic: rising sea levels, changes in climate and precipitation patterns, increasing severe weather events, and loss of fish stocks, birds and marine mammals.

Climate change caused by human activities is by far the worst threat to biodiversity in the Arctic. The Arctic as we know it â a vast icy landscape where reindeer roam, polar bears feast, and waters teem with cod and seals â will soon be frozen only in memory. "Only evaluation in the coming years will allow us to determine if we can still save the year-round Arctic sea ice through forceful climate protection or whether we have already passed this important tipping point in the climate system," Rex added, urging rapid action to halt warming. Climate warming has led to changes in the composition, density and distribution of Arctic vegetation in recent decades 1, 2, 3, 4. The Arctic region is warmer than it used to be and it continues to get warmer.
