Russian President Vladimir Putin declared an emergency after 20,000 tons of diesel fuel spilled into a river in the Arctic Circle. The accident is the second largest oil spill in terms of volume in modern Russian history, the Word Wildlife Fund (WWF) told AFP, as BBC News reported. The oil spread around 7.5 miles from […]
The Canadian Arctic is raising alarm bells for climate scientists. The permafrost there is thawing 70 years earlier than expected, a research team discovered, according to Reuters. It is the latest indication that the global climate crisis is ramping up faster than expected. The surface, which was frozen is now sinking and sprinkled with melt […]
By Jake Johnson An alarming study released Tuesday found that melting Arctic permafrost could add nearly $70 trillion to the global cost of climate change unless immediate action is taken to slash carbon emissions. According to the new research, published in the journal Nature Communications, melting permafrost caused by accelerating Arctic warming would add close […]
Scientists may need to more than double their assessment of how much carbon dioxide and methane thawing Arctic permafrost will release into the atmosphere this century, according to a study published this month. The paper, published in Nature Communications Aug. 15, said that previous estimates for how greenhouse gasses released by thawing permafrost would contribute […]
In two recent studies, scientists have looked into the future and into the past to see what might happen to the global climate if we fail to curb greenhouse gas emissions in time. The results are frightening. A study published Monday in Proceedings of the National Academy of Sciences examined how, once a certain threshold […]
By Robert McSweeney Emissions of CO2 and methane from wetlands and thawing permafrost as the climate warms could cut the “carbon budget” for the Paris agreement temperature limits by around five years, a new study says. These natural processes are “positive feedbacks”—so called because they release more greenhouse gases as global temperatures rise, thus reinforcing […]
A new industry is taking off in Alaska, as innovators help oil companies compensate for the irony that climate change is making oil exploration harder on the increasingly less frozen permafrost, NPR reported Monday. Ed Yarmak, for example, heads a company called Arctic Foundations that makes metal tubes filled with a refrigerant called thermosyphons. These […]
By Alex Kirby Methane emissions are the source of the greenhouse gas which, after carbon dioxide, probably causes climatologists more sleepless nights than any of the other gases. And now it appears they have quite a lot more to bother them than they had realized. Methane is reckoned to be at least 30 times more […]
A study published in Nature Climate Change Monday shows that thawing permafrost in the Arctic might produce more methane than previously thought. Methane has 28 times the Global Warming Potential (GWP) of carbon dioxide, so the findings indicate scientists might have to reassess how thawing permafrost will contribute to climate change. The research contradicts previous […]
