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 amount of ice melted from the frozen mass this summer, according to recently released data — and Earth's rising temperatures are suspected to be the main culprit.

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.

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.

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.

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.)
