An international team of experts supported by NASA and the European Space Agency (ESA) has combined data from multiple satellites and aircraft to produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to sea level rise.
«West Antarctic Ice Sheet loss over the last 11,000 years seen in new study: Results shed new light on what's happening today.»
May I remind you that Antarctica ice sheet has net ice sheet loss from loss at margins?
To clarify, I agree completely with Tom, with the caveat that I'm quite confident we can cool enough to halt further ice sheet loss in Antarctic — but that might require a sufficiently high forcing that it would be a really really bad idea for the rest of the climate.
«Thus the increased snowfall we report here has not led to thickening of the ice sheet, but is in fact another symptom of the changes that are driving contemporary ice sheet loss.»
However, this is balanced by substantial ice sheet losses on margins especially in West Antarctica as calving rates accelerate.
In West Antarctica, more widespread glacier losses increased ice sheet loss by 59 percent over a decade.
Dr Ian Joughin at the University of Washington, author of a recent study simulating future Antarctic ice sheet losses added: «This study does a nice job of revealing the strong thinning along the Amundsen Coast, which is consistent with theory and models indicating this region is in the early stages of collapse.»
Mercer further commented that the loss of ice shelves on the Antarctic Peninsula, as has since been observed, would be an indicator that this process of ice sheet loss due to global warming was underway.
(That is, if we simply held global mean temperature constant by injecting aerosols into the stratosphere, I have no idea whether that would be enough to halt Antarctic ice loss — probably not, in fact almost certainly not, though it would mean less ice sheet loss than would occur if we didn't do it.»
The loss of Arctic Sea Ice, substantial sea level rise from significant ice sheet losses and ocean acidification, risks that are well described in the publication are likely not unlikely events.
«Thus the increased snowfall we report here has not led to thickening of the ice sheet, but is in fact another symptom of the changes that are driving contemporary ice sheet loss,» said Dr Thomas.
The report notes that there are now many new sources confirming climate impacts, including the acceleration of ice sheet loss, and takes stock of new research and understanding on ocean acidification and warming, among other recent changes.
Alaska's glaciers contributed to one third of the world's ice sheet losses from 2005 to 2010, but a new study suggests melting, not calving as shown here, contributed to the most loss.
This number may seem small, but from 2005 to 2010, Alaskan glacier losses made up one third of the world's ice sheet losses, despite having 20 times fewer ice - covered areas than Greenland.
(1) the Arctic is already showing serious disruption, including sea ice retreat, amplified warming, ice sheet loss, permafrost and clathrate thawing, and initiation of natural carbon feedback cycle.
That ice sheet loss will proceed in a non linear fashion is certainly a given but from there on a whole variety of scenarios are possible, and we do not have the tools in hand to answer that question.
Moreover, recent studies suggest that ice sheet loss is accelerating and that future dynamics and instability could contribute significantly to sea level rise this century.
In draft versions at least, the new IPCC report does tackle the question of ice sheet loss, finding it «very likely» that melting ice and the expansion of the ocean due to its heating will lead to sea - level rise exceeding that of the last century.
The Antarctic sea ice is at record levels (implying that the ice sheet loss is slowing), the Arctic sea ice is steadily increasing in volume.
«Ice sheet loss is non linear by nature,» said Rignot.
You have station evidence and ice sheet loss.
Skeptic Argument: Ice Sheet losses are overestimated Response: Wu et al (2010) use a new method to calculate ice sheet mass balance.
Scientists have reported that the Arctic is currently warming at nearly double the global average rate, which is one of the key factors driving an unprecedented level of ice sheet loss.
