Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

This usually occurs in coastal and estuarine areas due to reducing land - based influence (e.g., either from reduced runoff and associated groundwater recharge, or from excessive water withdrawals from aquifers) or increasing marine influence (e.g., relative sea - level rise).

The IPCC Fifth Assessment Report (AR - 5) describes a strong relationship between carbon dioxide (CO2) and ice melt, with greater sea level rise based on increased atmospheric CO2.

The bases» exposure to coastal flooding is projected for the years 2050, 2070, and 2100 based on the National Climate Assessment's midrange or «intermediate - high» sea level rise scenario (referred to here as «intermediate») and a «highest» scenario based on a more rapid rate of increase.

Which forms the basis for the IPCC claim of high climate sensitivity (mean value of 3.2 C), resulting in significant global warming (up to 6.4 C warming by 2100), «extreme high sea levels», increased «heat waves», increased «heavy rains» and floods, increased «droughts», increased «intense tropical cyclones» — which, in turn, lead to crop failures, disappearance of glaciers now supplying drinking water to millions, increased vector borne diseases, etc. (for short, potentially catastrophic AGW — or «CAGW»).
