Sentences with phrase «ice volume on»
Thus the extra CO2 comes from the oceans, not from the ice and may or may not have helped to melt the ice (which I doubt)... But anyway there is little influence of the ice volume on the CO2 levels in the atmosphere, either direction.

Our simple scaling approximation implicitly assumes that ice sheets are sufficiently responsive to climate change that hysteresis is not a dominant effect; in other words, ice volume on millennial time scales is a function of temperature and does not depend much on whether the Earth is in a warming or cooling phase.
They found that 2017 tied 2012 for the lowest measured Arctic sea ice volume on record, though 2012 remains the year with the lowest summer minimum volume.
This warm period, much like the roman and medieval warm periods, will bump against the upper bound, opening the Arctic and creating massive snows that will bump it down again until the ice volume on land becomes massive enough to advance and cool us again.
when oceans are warm and wet it snows and increases ice volume on earth.
When earth needs cooling, it removes polar ice and turns on snowfall and builds ice volume on land that then advances

Not exact matches
This requires no such nerve - wracking processes; it is literally as easy as boiling water for the first hour or so, and then you'll keep an eye on it and stir it regularly until it is just a slip of its original volume, intense magnification of the original taste, and oh so gooey on a crepe (filled with fresh banana and mango, here), on ice cream or on a spoon.
Response to Comment on «Deep - Sea Temperature and Ice Volume Changes Across the Pliocene - Pleistocene Climate Transitions»
So, what tourism is impacting and actually what climate change is impacting is a relatively very small piece of that peninsula; but you know the impact on the peninsula if all that ice melts could be huge; when they talk about sea levels rising, you know, by inches and feet, you know if that ice along the peninsula melts they will add to the volume of the sea very quickly.
Building on this study, the team intend to produce a new reconstruction of global ice volume across the last glacial cycle, which will help to validate their proposition that certain boundaries can define windows of instability within the climate system.
But the large volumes of data on Arctic sea and land ice that IceBridge has collected during its nine years of operations there have also enabled scientific discoveries ranging from the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed to improvements in snowfall accumulation models for all of Greenlaice that IceBridge has collected during its nine years of operations there have also enabled scientific discoveries ranging from the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed to improvements in snowfall accumulation models for all of GreenlaIce Sheet are thawed to improvements in snowfall accumulation models for all of Greenland.
What is alarming is that the volume of water and the extent and rapidity of its movement is suprisingly much greater than previously believed, and that a possible, perhaps likely, effect of this on ice sheet dynamics is to make the ice sheets less stable and more likely to respond more quickly to global warming than previously expected.
On November 16, 2011, scientists announced that data from NASA's Galileo probe (which operated from 1989 to 2003) appear to reveal at least two bodies of liquid water the volume of the North America's Great Lakes underneath the surface ice of Europa.
Anderson, J.B., Shipp, S.S., Bartek, L.R., and Reid, D.E., 1992, Evidence for a grounded ice sheet on the Ross Sea continental shelf during the late Pleistocene and preliminary paleodrainage reconstruction: in Elliot, D.H. ed., Contributions to Antarctic Research III, Antarctic Research Series, Volume 57, American Geophysical Union, Washington, D.C., p. 39 - 62.

Even though the annual minimum usually happens in mid-September, ice had already reached its 5th - lowest annual volume on record at the end August.
The authors of a new study reviewing the volume data, detailed on Monday in the journal Nature Geoscience, are quick to caution, though, that one single year of rebound doesn't suggest any sea ice recovery, as the overall trend is still downward.
Writing in Nature Climate Change, two scientists from the Potsdam Institute for Climate Impact Research (PIK) say the melting of quite a small volume of ice on the East Antarctic shore could ultimately trigger a discharge of ice into the ocean which would result in unstoppable sea - level rise for thousands of years ahead.
Regarding my # 74: On sea ice thickness, here is an unreviewed but sensible discussion / analysis of Arctic sea ice volume and thickness as modeled by PIOMAS.
In the bowl of a stand mixer fitted with a paddle attachment, beat the Becel, icing sugar and pure vanilla extract on high speed until light and fluffy and doubled in volume, about two minutes.

«Eventually we'll move to a business of lower priced [NOOK] at higher volume» he explained, as well as confirming that plans to sell off the NOOK division — which Microsoft was tipped to be interested in buying at one point — had been put on ice for the moment, while the segment recovers.
- a lot of focus was put on sound effects in order to immerse players in the world of Hyrule - the development team worked with Sound Racer, a studio specialized in sound effects - this studio also worked on Xenoblade Chronicles X - they recorded more than 10 000 different sounds for the game - the team used a school bag to simulate the sound of rubbing leather - for the sound of «normal» footsteps, they mixed various kinds of sands - for the sounds of equipment, they had to search for various materials and find ways to use them - they used an actual block of ice to recreate the sound of footsteps on ice - with the ice block, it always ended up melting, or getting cracks when the staff had to walk on it - Link's footsteps were made by a woman - depending on Link's actions and the equipment he's using / wearing, the recorded sounds were separated out individually - the volume is changed as needed to make a particular sound stand out - check out sound effect samples here
However recently I've found myself wavering on the issue of how fast we'll see a transition to a virtually sea ice free state (less than 1M km ^ 2 off the Canadian Arctic Archipelago and the north of Greenland) and it's because of the PIOMAS volume results.
So unless the perimeter of the Greenland ice sheet is the exact same thickness as the entire ice sheet (say 3 km on average), an area loss there, of 15 %, will produce a much smaller % volume loss, than say if this area loss were smack dab in the middle of the Greenland ice sheet.
Extrapolating based on date from 1980 to the present yields and estimate around the 2040 for zero September ice volume while using an apparent steeper trend since 2000 yields an estimate around 2015 for the lower curve in fig. 1 or around 2020 using the upper curve as a guide.
Based on their choice of time - shift rather than volume shift to «correct» the models, I'd suspect that an assumption of lingering ice is built into the models.
The volume of grounded ice on Earth is 2.934 x 10 ^ 16 m ^ 3.
42 Eric, data on the volume of ice and potential sea level rise (pslr) associated with the various components are given in a table on this page:
Since the volume of ice at risk under BAU is within a factor of two of the volume of ice at risk during a deglaciation under orbital forcing, while the forcing is much more rapidly applied under BAU, looking at sea level rise rates in the paleo - record might actually be considered a search for lower limits on what to expect if reticence did not run so strongly in our approach.
To establish this uncertainty in the ice - volume record (Schweiger et al. 2011), we spent a significant effort drawing on most types of available observations of ice thickness thanks to a convenient compilation of ice thickness data (Lindsay, 2010).
Polar bears, walruses, seals and sub-ice algae and cod don't depend on sea - ice volume.
Given that thin ice — as you explained — boosts heat transfer from ocean to air, is a focus on ice volume as an indicator of the «health» of the system (for lack of a better word) a distraction?
Arctic sea ice has been shrinking more rapidly, falling to its lowest volume and second lowest area on record during the 2011 summer melt season.
Volume gives us an idea on how much freshwater is stored in Arctic sea ice — an important element in the global - Arctic hydrological cycle, i.e., the cycle of distillation due to freezing, and subsequent export, and melt.
Our Tietsche, et al., 2011 paper basically shows that both extent and volume can recover on similar time scales after extreme loss events, in particular for the thin ice that we have around nowadays.
Another possibility might be a slowing of deep circulation (not sure how much there is, mind), in which case the opposite occurs, and the surface waters heat up even faster, leading to yet more rapid surface melt, smaller winter ice volumes and so on.
Wili: As ice volume decreases, the fraction of volume which is new ice increases, and hence the year to year variability in new ice becomes a larger fraction of the total ice volume variability, so I don't think the smoothed downward slope will stay as smooth, i.e. you should expect bigger surprises to the upside on a given winter if it is cold and has heavy snow fall.
The buttresses of ice frozen around Antarctica's edges, hundreds of meters thick in many cases, are also in the sea, but they can act like doorstops and — once moved out of the way — can allow huge volumes of ice on the continent (in theory) to move toward the sea more easily.
In any event, the ice volume series clearly is not based solely on observations, as is the ice extent series.
At face value their numbers suggest the Arctic will be left with an extensive cover (> 4 million km ^ 2) of ice but only a small volume (< 2 million km ^ 3): i.e. on average the ice will be less than half a metre thick.
The fact that ice volume has a large positive coefficient on the lagged dependent variable (with differenced variables) means that something screwy is going on.
Thus the sea ice volume will not fall straight to zero on the PIOMAS graph, but curve round to the right.
If you're not refuting the volume analysis, then I can't see how you can say focusing on ice volume is «a bit funky» — it's clearly a more important measure of the system's ability to recover, which is the central point of this post.
«Preliminary data also indicate 2008 may represent the lowest volume of Arctic sea ice on record, according to the researchers.
