Americas

Change in precipitation patterns is predicted across the Americas with varying trends in annual rainfall shifts, leading to water-related disasters such as precipitation-induced floods, flash floods, drought with consequent wildfire danger and extreme events caused by the interaction of wind and water (e.g. storm surges). North America, in particular, faces more heat-waves in its urban centres and wildfires associated with higher temperatures and lower rainfall in the Western regions. In Northern America and in the Andean region of South America, climate change is projected to decrease annual runoff and water availability due to the retreat of glaciers and melting of snow cover. Along with changes in terrestrial and marine ecosystems, yields and quality of food crops and fisheries are expected to decrease, exposing more people to a much higher risk of food insecurity across the American continents. Coastal mega-cities, coastlines and adjacent coastal regions are also under threat from rising sea levels in North and South America as well. Intensifying tropical storm formation also poses additional perils to densely populated continental coastal areas and small islands of the Caribbean region.
