When you return, if the coin is embedded under the
ice, it's a good indication that power was out for long enough for the freezer to
rise above freezing point for long enough for some things to melt, but not long enough for frozen items to liquefy completely (remember that any
amount of
ice in milk means it's technically still frozen).
A large area of the Greenland
ice sheet once considered stable is actually shedding massive
amounts of
ice, suggesting that future sea - level
rise may be worse than expected, a team of scientists warned yesterday in a new study.
Most sea - level

Reducing the

He says previous predictive models of Greenland's
ice loss did not adequately take into account the faster movement of its southern glaciers, which is accelerating the
amount of
ice entering the ocean: «Greenland is probably going to contribute more to sea level
rise, and faster than predicted by these models.»
Despite the
rising sea level and therefore increasing pressure, the simulation showed that towards the end of the
ice age large
amounts of gas hydrate became unstable and the released gas escaped through the sediment to the seawater.

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the
amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level
rise by increasing land storage of water, protecting
ice sheets or artificially enhancing mountain glaciers).
Melting large quantities of
ice requires large
amounts of energy, and this slows the rate at which temperature would
rise with the same energy input but no melting, but it is not a major effect.
Since 1990, observed sea level has followed the uppermost uncertainty limit of the Intergovernmental Panel on Climate Change (IPCC) Third Assessment Report (TAR), which was constructed by assuming the highest emission scenario combined with the highest climate sensitivity and adding an ad hoc
amount of sea - level
rise for «
ice sheet uncertainty» (1).
In recent years, Greenland's
ice has been melting more and flowing faster into the sea — a record

rising temperatures are suspected to be the main culprit.

amount of heat required to melt enuf
ice corresponding to a 1 mm
rise in sea level is 1e20J.
Between April 2002 and April 2006, GRACE data uncovered

amount equivalent to a global sea
rise of 0.5 ± 0.1 millimeters per year.
The only problem with all the predictions about the level of the World Ocean
rising is that, the World Ocean is refusing to
rise up in support of the predictions, the other problem is that
ice is frozen fresh water and frozen fresh water only covers about 5 % of this planet above sea level and frozen water under the level of the World Ocean does not count as the World Ocean will fall a small
amount if that
ice melts, so if the
ice there is enough to get the World Ocean to
rise and significant
amount then it must be piled up very high, I cubic kilometer of water as
ice, should it melt, would make 1000 square kilometers
rise by one meter, so when you use this simple math then somewhere on the planet, above the level of the sea, then there must be over 500,000 cubic kilometers of
ice, piled up and just waiting to melt, strange that no one can find that
amount of
ice, all these morons who talk about the
rise of the World Ocean in tens of meters, this includes you Peter Garrett or Mr. 7 Meters, the
ice does not exist to allow this
amount of
rise in the World Ocean, it is just not there.

Actually since
ice is pretty much freshwater and hence less dense, when it melts in sea water the sea level will
rise but only by a very small
amount.
T, his was sho \ vn not only by the
rise of temperature at land stations, but also by the clccrease in the

Potential sea level

And remember, the satellite data are one small part of a vast
amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge
amounts of
ice melting at both poles, the «death spiral» of arctic
ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans,
rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...
This has never happened before because the sea
ice never retreated very much in the summer and the water temperature could not
rise above zero because of the
ice cover... The permafrost is acting as a cap for a very large
amount of methane (CH4), which is sitting in the sediments underneath in the form of methane hydrates.
Perhaps the best scientific evidence for the
amount of temperature
rise due to increasing CO2 comes from the relation between temperature and CO2 found in
ice cores.
There was an enormous
amount of snow and
ice to melt at low levels following the lia and when the temperatures started
rising around 1700 it started to melt.
Perhaps some gross thermomechanical process of restructuring the climate mechanisms (some small fraction of these were identified in the Stadium Wave paper, for instance) is ongoing, and the energy of restructuring — melting, subliming and carrying away Arctic sea
ice and Greenland and Antarctic land
ice net to the atmosphere, higher humidity absorbing gross water
amounts to a level impacting sea level
rise on the millimeter or sub-millimeter level, expansion of land due heat, or more likely erosion, silting and subsidence, and so on — is responsible for a Black Swan.
Natural variability and greenhouse gas emissions (and the resulting
rise in global temperatures) likely worked together to melt greater
amounts of Arctic sea
ice.
The researchers showed that even if carbon emissions are limited to the
amount consistent with a 2C
rise in temperatures — the internationally agreed goal — there will be enough CO2 in the atmosphere to avoid future
ice ages that could have started 50,000 or 90,000 years from now.
Rising global temperatures are causing increasingly large
amounts of
ice in the Arctic to melt, with possibly huge environmental consequences.
Global warming induced by increasing CO2 will cause
ice to melt and hence sea level to
rise as the global volume of
ice moves toward the quasi-equilibrium
amount that exists for a given global temperature [53].
The Sierra Nevada's mountain peaks have
risen measurably since 2012 as the Earth's crust rebounds from the net loss of 63 trillion gallons of water — an
amount equivalent to the entire annual
ice melt of the Greenland Ice She
ice melt of the Greenland
Ice She
Ice Sheet.
Since «there's an over two orders of magnitude (~ 120) difference between the
amount of energy needed to add a litre to the ocean from melting
ice (~ 334KJ)[and] thermal expansion of sea water (~ 40,000 KJ)», this means that sea - level
rise, often offered as a «proxy» for «global warming», is actually not important.
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.)
They are assuming that a 2C
rise in global temperatures will occur, sometime between 2015 and 2052, and this will affect particularly the sea
ice extent, winds and the
amount of open water on which these colonies depend.
