Coastal Impacts and Adaptation Issues Gary Lines Climate Change Meteorologist Meteorological Service of Canada Atlantic Stephen Schneider (Stanford University) "Don't be poor in a hot country, don't live in hurricane alley, watch out about being on the coasts or in the Arctic, and it's a bad idea to be on high mountains with glaciers melting.'' (Associated Press, 07/04/08) PROJECTIONS OF FUTURE CHANGES IN CLIMATE • Very likely that hot extremes, heat waves, and heavy precipitation events will continue to become more frequent • Likely that future tropical cyclones will become more intense, with larger peak wind speeds and more heavy precipitation – less confidence in total numbers • Extra-tropical storm tracks projected to move poleward with consequent changes in wind, precipitation, and temperature patterns Migration of Species Projected Global Sea Level Rise to 2100 2100 Best estimate About 40 cm Range 18 to 60 cm Present 3550% 1530% Thermal expansion Mountain glaciers 10-15% Greenland ice sheet ?
