"Zombie fires" and burning of fire-resistant vegetation are new features driving Arctic fires — with strong consequences for the global climate — warn international fire scientists in a commentary published in Nature Geoscience.
Experts at the University of Helsinki, Finland, are describing how insect communities are transforming in the Arctic as a result of climate change. The researchers have investigated the presence of small yet important insect predators known as parasitoids.
Wildfires blazed along the Arctic Circle this summer, incinerating tundra, blanketing Siberian cities in smoke and capping the second extraordinary fire season in a row. By the time the fire season waned at the end of last month, the blazes had emitted a record 244 megatons of carbon dioxide — that’s 35 percent more than last year, which also set records.
A multinational investment bank has ended support for offshore drilling in the Arctic amid efforts to tackle climate change, a move that could affect future funding for oil and gas projects in Alaska, a newspaper said.
Last year, just a handful of plants and animals in Zackenberg, Northeast Greenland were able to reproduce due to vast amounts of un-melted snow covering the ground well into summer, a study by Danish researchers found.
Gigantic forest fires have regularly raged through the vast expanses of Russia's Siberia, but the magnitude of this year's blazes has reached an exceptional level with fears of a long-term impact on the environment.
