The Intergovernmental Panel on Climate Change (IPCC) Special Report on Extreme Events (2012) indicates that some observed impacts of climate change – in particular, changes in rainfall and sea-level rise – are unfolding considerably faster than had previously been anticipated. Projected climatic changes, such as rising temperatures, increasingly erratic weather and changing frequencies and intensities of extreme weather events, are expected to adversely affect people’s livelihoods and alter different forms of human mobility including voluntary migration, displacement and planned relocation. The IPCC Working Group 2 on Adaptation argues that human mobility associated with climate change may become a defining humanitarian and development issue in the coming decades (Summary for Policymakers, March 2014).
