A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends.
Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate.
What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change?
According to a survey published in the November 30 issue of the journal Nature, melting permafrost in the northern climes is releasing large amounts of methane and carbon, amplifying the global warming effect.
Scientists estimate that if global warming continues even at a moderate pace, a third of the earthâ€™s permafrost will be gone by 2200.
Among the worrisome environmental effects of global warming is the thawing of Arctic permafrost---soil that normally remains at or below the freezing point for at least a two-year period and often much longer.
An Australian-led team of scientists says it has determined the amount of frozen carbon in Earth's northern regions is more than double previous estimates. We now estimate the deposits contain over 1.5 trillion tons of frozen carbon, about twice as much carbon as contained in the atmosphere, said Charles Tarnocai of Agriculture and Agri-Food Canada, the study's lead author. Pep Canadell, executive director of Australia's Global Carbon Project and study co-author, said the existence of...
The vast amount of carbon stored in the arctic and boreal regions of the world is more than double that previously estimated, according to a study published this week.
â€œA slow-motion time bomb.â€ Thatâ€™s what one ecologist calls the looming threat of trapped greenhouse gases in the melting Arctic.
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.
