melting polar
ice sheets are
contributing more to sea level rise than the demise
of mountain glaciers.
The
melting of Greenland
contributes to the global sea level, but the loss
of mass also means that the
ice sheet's own gravitational field weakens and thus does not attract the surrounding sea as strongly.
Rapidly increasing

contribute although
ice sheet contribution is a small part

Additionally, it is postulated that the warming climate will likely extend
melt seasons, leading to increases in biological activity and thus
contributing further to the darkening
of glaciers and
ice sheets (Benning et al., 2014).

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.

of ground water, and
melting of the polar
ice sheets have added water to the oceans,
contributing to sea level rise.
It must be pointed out that the
ice has been thinning more appreciatively in west Greenland
of late and that
ice sheet melting can only
contribute a moderate amount
of freshwater volume each year.
[Response: Here's a simple back -
of - envelope consideration for the future: if the Greenland
ice sheet melts completely over the next ~ 1,000 years (Jim Hansen argues in the current Climatic Change that the time scale could be centuries), this would
contribute an average flux
of ~ 0.1 Sv
of freshwater to the surrounding ocean.
The conclusion that the Greenland
ice sheet melting was significantly enhanced by the increased N. Hemispheric insolation during the Eemian affects projections
of future (near term) sea level rise insofar as Greenland
melt contributed to the Eemian sea level rise.
Land - based
ice in glaciers and
ice -
sheets will keep
contributing to sea level rise as long as
melting exceeds snowfall accumulation; stopping the growth
of temperature would not stop the net
melting.
The
melting of the Greenland
ice sheet is projected to continue and to
contribute to sea level rise after 2100.
Melting of glaciers and
ice sheets is also
contributing to sea level rise at increasing rates.6
The
melting of the Antarctica
ice sheet, on the other hand,
contributed five millimeters to the sea level rise during the same period.
The warming
of oceans and the
melting of ice sheet and glaciers, particularly in Antarctica and Greenland, have
contributed to the hastening sea level rise.
The objects would have exploded over North America or slammed into it, or both, shattering and
melting ice sheets, sparking extreme wildfires, and fueling hurricane - force winds — all
of which could have
contributed to changes in climate that led to the cooling
of the Younger Dryas period.
The report, sponsored by the federal National Oceanic and Atmospheric Administration, found unprecedented temperatures this year in the Arctic
contributed to a record - breaking delay in the annual freeze — prompting extensive
melting of the Greenland
ice sheet and land - based snow cover.
The cities» lawsuits allege — supported by modern climate science — that major oil and natural gas companies
contribute substantially to global warming by extracting and using fossil fuels, which emit massive quantities
of heat - trapping greenhouse gases into the atmosphere, causing ocean waters to warm and
ice sheets to
melt, and thus, sea levels to rise, endangering coastal communities.
It may also mean more habitat for dark microbes, which can
contribute to the darkening
of the
ice sheets and therefore to the
melting.
Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount
of ice and water they discharge into the ocean,
contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated
melting also adds freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.7 (See Greenland
ice sheet hotspot for more information.)
Great progress has been made recently in assessing the current rate
of mass loss from the
ice sheets (Shepherd et al., 2012), as well as monitoring the changing snowfall, surface
melting, and temperature
contributing to the changes.
For example, the
melting of the Greenland
ice sheet broke previous records in 2002, 2005, and 2007, and seasonal
melting from 1996 to 2007 was above average compared with the 1973 - 2007 period.10, 11 The
melting of the Greenland
ice sheet contributed around 0.02 inch (0.6 millimeter) to global sea - level rise in 2005 — more than double the 1996 contribution.4 From 1993 to 2003 the average rate
of sea - level rise increased to about 0.12 inches (3.1 millimeters) per year.12 That means that in 2005 Greenland could have
contributed 19 percent
of the average annual global sea level rise rate.
I understand that
melting sea
ice does not
contribute to sea level rise, but the fact that Antarctic sea
ice is at record high levels seems inconsistent with proposed rapid
melting of Antarctic
ice sheets.
