Small increase in temperature of intruding water could lead to very big increase in loss of ice, scientists say
Scientists now have a better understanding of the risks ahead and a new early warning signal to watch for.
As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published in Nature Geoscience. The study, led by researchers from the University of Cambridge and the University Center in Svalbard, Norway, identified large stocks of methane gas leaking from groundwater springs unveiled by melting glaciers.
Scientists are getting a better handle on how fast Greenland's ice is flowing out to sea. Old models that used Antarctica as a baseline were way off the mark.
Giant ice sheets, ocean currents and permafrost regions may already have passed point of irreversible change
Most marine-terminating glaciers in the Northern Hemisphere are shrinking; some have completely left the water.
Patagonian ice fields are among some of the fastest-melting glaciers on the planet. As these glaciers disappear, the earth that once lay beneath them is rebounding upwards at rates much faster than expected.
