For some low lying states like the Maldives, Kiribati, and some of the Bahamas, the risks from sea level rise threaten their physical existence, as they would very easily be inundated by sea levels in excess of one metre above current levels – levels that can be reached by 2100, if significant action is not taken immediately to reduce and ultimately limit the atmospheric concentration of greenhouse gases to well below 350 parts per million (ppm) in the long run.
For other states, their social-economic viability will be compromised, inter alia:
By the rising seas which will damage their coastal zones, where the majority of their socio-economic infrastructure is located;
By the saline intrusion into their coastal aquifers which will negatively impact on their drinking water and agricultural activities;
By the destruction to their coral reefs and their fisheries habitats that result from increases in ocean acidification and rising temperatures; and
By the impact of stronger tropical cyclones that can destroy years of positive development in a matter of hours, as has been demonstrated time and time again, including by the recent experiences of Cook Islands (2005); Cuba (2008); Fiji (2008); Grenada (2004); Haiti (2004; 2008); Niue (2004); and others.
