Protection of Coastal Areas from Rising Sea Level

Recently released Fifth Assessment Report (AR5) of Intergovernmental Panel on Climate Change (IPCC) suggests that global mean sea level has risen by 190 mm over the period 1901-2010. The satellite based linear trend during 1993-2011 is estimated to be 3.20.5mm/year that is about 60% higher than the best estimate of 2.0mm/year by the Intergovernmental Panel on Climate Change (IPCC), 2007 assessment report. However, the estimated sea level rise by the tide gauge records (of over 200) for the period 1993-2009 is found to be about 2.80.8mm/year.
