Climate change is expected to affect every country in the world, but its impact will not be felt equally across all regions and some will be worse hit than others because of a range of different threats.
Developing countries, places with widespread poverty, and countries with ineffective governments sometimes face the gravest risks from the changing climate, and are usually poorly equipped to find ways to prepare for and prevent environmental threats.
Measuring the future impact of climate change is very challenging, because scientists’ climate change projections cannot be completely exact and because there are many different factors that come into play such as the risk of extreme weather events and rising temperatures. There are other non-climatic factors that also determine how severely a city or country will be impacted by climate change. Niall Smith, who analyzes regions’ climate change vulnerability for the global risk consulting firm Maplecroft, tells TIME that it’s also necessary to weigh in what’s happening politically and socially in a region to figure out if the country can prepare.
