Résumé(disponible en anglais seulement)
Sea-level projections are estimated in Arctic regions by combining data on global sea level changing due to a warming climate, postglacial rebound ("vertical land motion"), and sea-level fingerprinting - the contribution to global sea-level rise from each major ice-cap in the world. This indicator also presents evidence of the effects of sea-level rise on the Mackenzie Delta and on other coastal areas along the Beaufort Sea in the NWT. Sea-level projections for NWT communities along the Beaufort Sea were estimated for this NWT State of Environment report by Thomas James, Geological Survey of Canada, Natural Resources Canada, based on the methods described in a study generated by the Nunavut Climate Change Partnership. Estimates and uncertainties of vertical crustal motion were derived from information on past sea levels, as described in James et al. (2011). This indicator is an output of the Earth Sciences Sector (ESS) Climate Change Geoscience Program of Natural Resources Canada. Text and calculations are by Thomas James, peer-reviewed by Don Forbes. This is ESS contribution number 20110177. The "NWT focus" and "looking forward" sections were drafted by ENR, GNWT.
