EventMethane bubbles are surfacing from thawing permafrost near Fairbanks, Alaska, marking a tipping point as the Arctic releases three times as much carbon as is currently in the atmosphere. Researchers say the added emissions could raise global temperatures by roughly 0.5 °C by the end of the century.
Methane bubbles are leaking from thawing permafrost in Alaska, a process that could add nearly half a degree Celsius to global warming by 2100, as scientists warn the Arctic is no longer a carbon sink.
Scientists warn that thawing permafrost in the Arctic is releasing large amounts of methane and carbon dioxide, adding to global warming.
Methane bubbles are emerging from thawing permafrost near Smith Lake in Fairbanks, Alaska—an indication that the Arctic’s previously frozen carbon is now contributing to global warming, with studies warning that permafrost emissions could add a quarter‑degree Celsius of warming by 2100.
Methane bubbles were seen at Smith Lake in Fairbanks, Alaska, as thawing permafrost releases greenhouse gases, adding to global warming.
Heat‑trapping gas that had been frozen in Arctic ground is slowly leaking, adding to global warming.
