Geospatial tools for addressing disaster management, coastal settlements and climate change issues
Zilkoski, David, Douglas Brown and Galen Scott
According to the International Panel on Climate Change (IPCC) Global average sea level rose at an average rate of 1.8 [1.3 to 2.3] mm per year over 1961 to 2003. The rate was faster over 1993 to 2003, about 3.1 [2.4 to 3.8] mm per year..(IPCC 2007) Mid-line projections for sea level rise over the next century range from 2.8 to 4.3 mm/yr for the 5 scenarios presented by the IPCC report. The impacts of the melting of ice sheets in Greenland and Antarctica are not fully addressed by the IPCC models because a basis in published literature is lackingg (IPCC 2007). Whatever the overall global sea level rise rate turns out to be, it will be experienced differently by coastal communities around the world depending on the motion of the land upon which the communities are built. The impact of rising waters can be compounded dramatically if the coastal zone is subsiding. Clearly, high accuracy measurements of these relative motions will aid in the assessment of possible impacts, mitigations, and adaptation strategies to climate change and associated sea level rise in coastal settlements.
