Approximately 95 million Americans lived in coastal communities in 2017  and in 2013, Canada had roughly 6.5 million coastal residents , while Mexico had 19 million people living in coastal municipalities in 2015 . Sea level rise around North American coastlines  is projected to be greatest along the coasts of Atlantic Canada, northern Gulf of Mexico for the USA and the Pacific coast of Mexico . Sections 14.5.2.1, 14.5.5.1.3 and 14.5.5.2.3 describe SLR impacts.

Adaptation planning and implementation to address SLR and coastal flooding have been initiated across many cities and settlements in North America, but preparedness varies .
