Given the increased levels of certainty regarding human - induced global warming (from 90 to 95 %), more robust projections on sea - level rise and data on melting of ice sheets, and the «carbon budget» for staying below the 2 °C target, the WGI conclusions together with other AR5 component reports are likely to put more pressure on the UNFCCC parties to deliver by 2015 an ambitious agreement that is capable of preventing dangerous anthropogenic interference with the climate system.

These large CO2 deserts cover the northern ice sheets with dust, as is recorded in the ice core data, and the ice sheet albedo is lowered sufficiently so that the next insolation maxima can melt the ice sheets.

The data used in the study included more than 455,000 independent estimates of changes in the land elevation of the vast ice sheets covering Antarctica, both in the western part of the continent, where ice is melting more rapidly, and in the east, where the ice is considered to be more stable, for the time being at least.

As explained in the press release, the scientists began with the measure of sea level rise between 2005 and 2013, then deducted the amount of rise due to meltwater (e.g., melting ice sheets and loss of glacier mass worldwide) and then the amount of rise due to the expansion of water from the warming in the upper portion of the world's oceans (which scientists have good data on).

For their study, Hansen and his colleagues combined ancient paleo - climate data with new satellite readings and an improved model of the climate system to demonstrate that ice sheets can melt at a «non-linear» rate: rather than an incremental melting as Earth's poles inexorably warm, ice sheets might melt at exponential rates, shedding dangerous amounts of mass in a matter of decades, not millennia.

However, with the new evidence that changes in atmospheric and thus oceanic circulation may have obscured changes in sea level (http://environment.newscientist.com/article/dn12547-flatter-oceans-may-have-caused-1920s-sea-rise.html), is there any evidence that the previously apparently static sea levels caused groups to self - censor data on ice sheet melting?
