Sea level rise

In 1988, the authorities claimed that sea rise would "completely cover this Indian Ocean nation of 1196 small islands with in the next 30 years." The Intergovernmental Panel on Climate Change's 2007 report predicted the upper limit of the sea level rises will be 59 centimetres (23 in) by 2100, which means that most of the republic's 200 inhabited islands may need to be abandoned.  According to researchers from the University of Southampton, the Maldives are the third most endangered island nation due to flooding from climate change as a percentage of population. Former president Mohamed Nasheed said in 2012 that "If carbon emissions continue at the rate they are climbing today, my country will be under water in seven years." He has called for more climate change mitigation action while on the American television shows The Daily Show and the Late Show with David Letterman, and hosted "the world's first underwater cabinet meeting" in 2009 to raise awareness of the threats posed by climate change.  Concerns over sea level rise have also been expressed by Nasheed's predecessor, Maumoon Abdul Gayoom. 

In 2008, Nasheed announced plans to look into purchasing new land in India, Sri Lanka, and Australia because of his concerns about global warming, and the possibility of much of the islands being inundated with water from rising sea levels. The purchase of land will be made from a fund generated by tourism. The president explained his intentions: "We do not want to leave the Maldives, but we also do not want to be climate refugees living in tents for decades". By 2020, Maldives plans to eliminate or offset all of its greenhouse gas emissions. At the 2009 International Climate Talks, Nasheed explained that: For us swearing off fossil fuels is not only the right thing to do, but it is also in our economic self-interest... Pioneering countries will free themselves from the unpredictable price of foreign oil; they will capitalise on the new green economy of the future, and they will enhance their moral standing giving them greater political influence on the world stage. In 2020, a three-year study at the University of Plymouth found that as tides move sediment to create higher elevation, the islands, and also Tuvalu and Kiribati, may rise instead of sink.
