Faster than normal
ice loss rates continued through August, a transition month when ice loss typically begins to slow.
Not exact matches
Based on what we know, we can expect the rapid
ice loss to
continue for a long time yet, especially if ocean - driven melting of the
ice shelf in front of Pine Island Glacier
continues at current
rates,»
Lead author Dr Malcolm McMillan from the University of Leeds said: «We find that
ice losses continue to be most pronounced along the fast - flowing
ice streams of the Amundsen Sea sector, with thinning
rates of between 4 and 8 metres per year near to the grounding lines of the Pine Island, Thwaites and Smith Glaciers.»
Individual responses
continue to be based on a range of methods: statistical, numerical models, comparison with previous
rates of sea
ice loss, composites of several approaches, estimates based on various non sea
ice datasets and trends, and subjective information (the heuristic category).

If both Greenland and West Antarctica shed the entirety of their
ice burden, global sea levels would rise by 12 to 14 m. Although these icecaps would not disintegrate within a century, the
loss of even a third of their mass — quite plausible if the
rate of polar
ice loss continues to double each decade — would force up the oceans by at least 4 m, with disastrous socioeconomic and environmental consequences.
In many rivers fed by glaciers, there will be a «meltwater dividend» during some part of the 21st century, due to increasing
rates of
loss of glacier
ice, but the
continued shrinkage of the glaciers means that after several decades the total amount of meltwater that they yield will begin to decrease (medium confidence).
Zwally deemed it necessary to acknowledge climate change fears and suggested that if the
rate of dynamic thinning
continues, Antarctica could begin exhibiting a net
loss of
ice within the next 20 years, but only if there was no compensating snowfall.

However, the
rate of
ice loss accelerated in July, and faster than normal
loss rates continued through August, a transition month when
ice losses typically begins to slow.
While the
loss of glacier mass has
continued for the past few decades with a slight increase in recent years, the
rate of mass
loss from the Greenland
ice sheet has dramatically increased in the past decade and
continues to increase.
Whether or not this
rate of
ice loss will
continue will depend on what the weather does over the next few weeks.
