Arctic’s Rapid Sea Ice Loss Threatens Wildlife

Arctic’s Rapid Sea Ice Loss Threatens Wildlife

The loss of Arctic sea ice is bad news for the Pacific walrus, and for polar bears: the walrus has further to swim to dig for clams on the sea floor, and the polar bear has less chance of catching seals. But the real problems begin at the base of the food chain. Since the end of the last century, more than two million square kilometers of sea ice … Read More

Arctic Warming Could Cost Upwards of $60 Trillion

The worldwide impacts of a rapidly warming Arctic could cost the global economy an estimated $60 trillion, nearly equal to the entire global economy in 2012, according to a new study. That report, published Wednesday in the journal Nature, is the first to analyze the potential economic costs of rapid Arctic warming.… Read More

Arctic’s Boreal Forests Burning At ‘Unprecedented’ Rate

Arctic’s Boreal Forests Burning At ‘Unprecedented’ Rate

Wildfire activity in the boreal forest biome, which is also known as taiga, plays a crucial role in the globe’s carbon budget, since these forests represent almost 10 percent of the planet’s land surface and contain more than 30 percent of the planet’s terrestrial carbon stocks. Globally, the boreal forest covers 6.41 million square miles, forming … Read More
