Sentences with phrase «potential of polar ice sheets»

Not exact matches

Impacts of thermal expansion and melting mountain glaciers can be predicted with moderate confidence, but more uncertainty remains in the potential behavior of polar ice sheets.

Polar amplication is of global concern due to the potential effects of future warming on ice sheet stability and, therefore, global sea level (see Sections 5.6.1, 5.8.1 and Chapter 13) and carbon cycle feedbacks such as those linked with permafrost melting (see Chapter 6)... The magnitude of polar amplification depends on the relative strength and duration of different climate feedbacks, which determine the transient and equilibrium response to external forcings.

In the absence of accurate data, the IPCC also did not take into account the full potential impact of the destabilization of land - based ice sheets in the polar regions in the projections in its last report.

Melting Arctic ice - sheets will reduce ocean salinities (IPCC, 2001), causing species - specific shifts in the distribution and biomass of major constituents of Arctic food webs, including poleward shifts in communities and the potential loss of some polar species (such as the narwhal, Monodon monoceros).
