Lecture 7. Sea Level Rise and Planning: Global Perspective
Warming Projections 2 degrees: goal of international negotiations (UN Framework Convention on Climate Change) 3 degrees: 2007 IPCC projections 4 degrees: recent report by World Bank suggests this is likely if we do not change course
Sea Level Rise IPCC: global average sea level rise projections between 1-6 meters by the end of 21st century (IPCC) Recent reports indicate IPCC may have significantly underestimated rates of SLR
Sea Level Rise Tremendous variation on a regional and local scale Currents Geological factors Glacial melting Glacial isostatic adjustment Volume of polar ice sheets http://geology.com/sea-level-rise/
Climate Change Displacements Estimates of climate change migrations 50-250 million people by 2050 Variety of reasons for displacement: Sea level rise Change in rain fall: desertification and flooding Glacial melting Extreme weather and human disasters
