The biggest changes were seen in West Antarctica, where more than a fifth of the ice sheet has retreated across the sea floor faster than the pace of deglaciation.

While the ECS factors in such «fast» feedback effects as changes in water vapor — water itself is a greenhouse gas, and saturates warm air better than cold — they argued that slow feedbacks, such as changes in ice sheets and vegetation, should also be considered.

He and colleagues want to figure out whether the dark tinge on the ice from those microbial residents helps explain why the ice sheet is melting faster than expected from climate change alone.

«Based on the UN climate panel's report on sea level rise, supplemented with an expert elicitation about the melting of the ice sheets, for example, how fast the ice on Greenland and Antarctica will melt while considering the regional changes in the gravitational field and land uplift, we have calculated how much the sea will rise in Northern Europe,» explains Aslak Grinsted.

But that could soon change, Rignot said, because the rate at which ice sheets are losing mass is increasing three times faster than the rate of ice loss from mountain glaciers and ice caps.

Indeed, one of the findings in the recent paper by Overpeck et al. (this weeks Science), is that even as the Greenland ice sheet melts faster than originally expected, it still won't provide sufficient meltwater forcing of the North Atlantic circulation (which is the feature of the climate system most commonly implicated in the discussion of «tipping points») to force any sort of threshold change.

It's the fast - moving ice that determines how the ice sheet responds to climate change on a short timescale,» said Robert Bindschadler, a NASA scientist at the Goddard Space Flight Centre in Maryland, one of the study's co-authors.

That estimate was based in part on the fact that sea level is now rising 3.2 mm / yr (3.2 m / millennium)[57], an order of magnitude faster than the rate during the prior several thousand years, with rapid change of ice sheet mass balance over the past few decades [23] and Greenland and Antarctica now losing mass at accelerating rates [23]--[24].

and on the racetrack man it was a little bit more satisfying to my taste though we've talked about the exhaust I have it set in the track setting let's quiet it down a little bit so you can hear the difference now I've set that separately from everything else so let's put it stealth what happened to the engine sound that's pretty that's pretty amazing man stealth is really stealth and then go back to track Wow actually a really big difference that's that's pretty great the Corvette has always been a strong value proposition and nowhere is that more evident than this zr1 giving you a nearly unbeatable track performance per dollar now the nice thing is on the road this doesn't feel like a ragged edge track machine either you could genuinely drive it every day the compromises are few and that's what makes this car so special if you like what you see keep it tuned right here and be sure to visit Edmunds.com [Music]

On the other hand, when an editor either adds to or creates a style sheet to pass back to the writer along with the fully edited manuscript it provides a detailed account of the types of changes made that can be assessed much faster than the entire manuscript.

Indeed, one of the findings in the recent paper by Overpeck et al.

And this is just one element in the sea level rise — small ice caps are melting faster, thermal expansion will increase in line with ocean heat content changes and Antarctic ice sheets are also losing mass.

Robert Bindschadler of NASA and Tad Pfeffer at the University of Colorado, both glacier specialists, told me that they saw scant evidence that a yards - per - century rise in seas could be produced from the ice sheets that currently cloak Greenland and West Antarctica, which are very different than what existed in past periods of fast sea - level changes.

In probing the fast - changing ice sheets of Antarctica and Greenland, Gordon Hamilton of the University of Maine exemplified the qualities in the rare breed of scientists, engineers and field staff willing to go to extremes — literally — to help clarify the pace at which seas will rise as warming glacial ice melts.

If the surface temperature is slow to catch up to that imbalance then the energy imbalance remains large, and we can have sufficient net heating to cause much faster changes in the ice sheets than from the comparatively smaller imbalances caused by the changes in Earth's orbit associated with the glacial periods in the past.

In their latest Science paper submittal Jim Hansen, et al. argue that we must reduce atmospheric CO2 to below 350 ppm because so - called «slow feedbacks» such as changes in ice sheet albedo are occurring much faster than expected.

Climate alarm depends on several gloomy assumptions — about how fast emissions will increase, how fast atmospheric concentrations will rise, how much global temperatures will rise, how warming will affect ice sheet dynamics and sea - level rise, how warming will affect weather patterns, how the latter will affect agriculture and other economic activities, and how all climate change impacts will affect public health and welfare.

The fast response from oceans and vegetation (opposite to each other) leads to a change of about 3 ppmv / °C, while the long term response (including ice sheet / vegetation surface area and - deep - ocean current changes) is about 8 ppmv / °C.

Eric Rignot: Observations suggest that ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated

1 Comment on «Eric Rignot: Observations suggest that ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated»

The observations from the last 20 + years clearly suggest that ice sheets and glaciers can change faster, sooner and in a stronger way than anticipated but this information has not yet filtered into more realistic projections.

«These changes on the Greenland ice sheet are happening fast, and we are definitely losing more ice mass than we had anticipated,» said Isabella Velicogna, lead author of the study last year.

Based on evidence from Earth's history, we suggest here that the relevant form of climate sensitivity in the Anthropocene (e.g. from which to base future greenhouse gas (GHG) stabilization targets) is the Earth system sensitivity including fast feedbacks from changes in water vapour, natural aerosols, clouds and sea ice, slower surface albedo feedbacks from changes in continental ice sheets and vegetation, and climate — GHG feedbacks from changes in natural (land and ocean) carbon sinks.

The retreat of glaciers and shrinking of the Greenland ice sheet in the Arctic, for example, is predicted to cause significant sea - level rise, changes in the salinity of our oceans, and altered feedback loops that will make the Arctic warm up even faster.

The likelihood of the complete loss of Arctic summer sea ice by 2030, faster melting of the vast Greenland ice sheets, and the rapid and quickening thaw of permafrost regions indicate that the window for arresting climate change before tipping points are reached is rapidly closing.

Actually Fielding's use of that graph is quite informative of how denialist arguments are framed — the selected bit of a selected graph (and don't mention the fastest warming region on the planet being left out of that data set), or the complete passing over of short term variability vs longer term trends, or the other measures and indicators of climate change from ocean heat content and sea levels to changes in ice sheets and minimum sea ice levels, or the passing over of issues like lag time between emissions and effects on temperatures... etc..

(04/01/2013) Warming about twice as fast as the rest of the world, the Arctic is already undergoing massive upheavals from climate change: summer sea ice is thinning and vanishing, land based ice sheets are melting, and sea levels are rising.

16 Sea level rising by thermal expansion AND ice melt Sea ice melting (Arctic and Antarctic) Glaciers melting worldwide Arctic and Antarctic Peninsula heating up fastest Melting on ice sheets is accelerating More severe weather (droughts, floods, storms, heat waves, hard freezes, etc.) Bottom line: These changes do not fit the natural patterns unless we add the effects of increased Greenhouse gasses Signs that global warming is underway

That estimate was based in part on the fact that sea level is now rising 3.2 mm / yr (3.2 m / millennium)[57], an order of magnitude faster than the rate during the prior several thousand years, with rapid change of ice sheet mass balance over the past few decades [23] and Greenland and Antarctica now losing mass at accelerating rates [23]--[24].

Joughin and others, 2008 observed that seasonal drainage of meltwater to the glacier bed induces a uniform acceleration of 50 — 150 meters / year over a ~ 300 km long section of the West Greenland margin that is not drained by outlet glaciers, causing a large fractional acceleration of the interior ice sheet but a small fractional change in the speed of fast - moving outlet glaciers.

Model studies for climate change between the Holocene and the Pliocene, when Earth was about 3 °C warmer, find that slow feedbacks due to changes of ice sheets and vegetation cover amplified the fast feedback climate response by 30 — 50 % [216].

Re my suggestion of a step change, I was indeed thinking of an ocean circulation organization happening fairly quickly, potentially faster than ice sheet melt, and nothing like millions of years.

One effect of the changes in atmospheric circulation will be faster transfer of heat to the Greenland Ice Sheet.
