"Although breakup of the ice shelves does not contribute directly to sea-level rise - since ice shelves, like sea ice, are already floating - we now know that these breakups have implications for the inland ice
," said Helen Fricker, a co-author of the review.
Anders Levermann of the Potsdam Institute for Climate Impact Research (PIK) published a similar study in 2017, looking at ice shelf thinning in Antarctica, and finding that melting ice shelves can have a knock-on effect on ice flows, accelerating inland ice
melt and pushing up the sea level.
Linking Cree hunters' and scientific observations of changing inland ice
and meteorological conditions in the subarctic eastern James Bay region, Canada.
The same in smaller glaciers contributed.Also in the neighbourhood was melting of inland ice
caps, most of whose waters remained in inland seas, reservoirs, the Earth's fauna and flora o flowed into oceans.
According to the ESA report, the collapse of the shelves allows inland ice
to flow faster into the ocean and this dramatically adds to sea-level increase in coastal regions.
It offers whale safaris, iceberg sightseeing, helicopter flights over inland ice
and visits to sled-dog handlers, who, besides transporting fish, now give excursions for tourists as a small sideline.
The base was situated on the inland ice
, and is at its coldest in February.
Radio surveys show that some of the bed rock underlying the ice streams lies well below sea level, making inland ice
vulnerable to floodwaters if the shelf were to collapse.
"What the break-up means in terms of inland ice
acceleration and draw-down of the ice sheet remains to be seen, but will be revealed by the GPS data recovered, which we are now processing at Aberystwyth."
New studies reveal that the effect of meltwater on acceleration and ice loss--through fast-moving outlet glaciers that connect the inland ice
sheet to the ocean--is much more complex, as a kind of plumbing system evolves over time at the base of the ice, expanding and shrinking with the volume of meltwater.
We were headed to the nearby glass ocean that is Greenland's enormous inland ice
Where Oluf felt sunk in aridity, Thea's disconnection is akin to Nansen's polar expedition: like his boat, Fram (Forward), she feels "a drifting laboratory on inland ice
