7 Regions Poised To Feel Climate Change Pain And What They’re Doing About It

Climate change will not affect every place equally. Here’s what seven regions in the bull’s eye are doing about it now.

It could have been the edge of the Sahara Desert or even Death Valley, but it was the remains of a large orchard in the hills above the city of Murcia in southern Spain last year. The soil had broken down into fine white, lifeless sand, and a landscape of rock and dying orange and lemon trees stretched into the distance. 

A long drought, the second in a few years, had devastated the harvest after city authorities had restricted water supplies, and farmers were protesting in the street. It was a foretaste of what may happen if temperatures in the Mediterranean basin continue to rise and desertification grows.

All round the world, farmers, city authorities and scientists have observed changing patterns of rainfall, temperature rises and floods. Fifteen of the 16 hottest years have been recorded since 2000. Carbon dioxide and other greenhouse gas emissions steadily climb. Oceans are warming and glaciers, ice caps and sea ice are melting faster than expected. Meanwhile, heat and rainfall records tumble.

The evidence for the onset of climate change is compelling. But who and where is it hitting the hardest? How fast will it come to Africa, or the U.S.? What will be its impact on tropical cities, forests or farming? On the poor, or the old? When it comes to details, much is uncertain. 

Mapping the world’s climate “hot spots” and identifying where the impacts will be the greatest is increasingly important for governments, advocacy groups and others who need to prioritize resources, set goals and adapt to a warming world.

But lack of data and different priorities make it hard. Should scientists pinpoint the places most likely to see faster-than-average warming or wetter winters — or should they combine expected physical changes with countries’ vulnerability? Some hot spot models use population data. Others seek to portray the impacts of a warming world on water resources or mega-cities. Global bodies want to know how climate might exacerbate natural hazards like floods and droughts. Economists want to know its impacts on resources. Charities want to know how it will affect women or the poorest. 

What follows is a subjective appraisal of the seven most important climate hot spots, based on analysis of numerous scientific models and personal experience of observing climate change in a variety of places. Delta regions, semiarid countries, and glacier- and snowpack-dependent river basins are all in the front line. But so, too, are tropical coastal regions and some of the world’s greatest forests and cities.
