The “Trump” States, Southeastern USA will be hit with the highest climate change costs

New study finds that climate change costs will hit Trump country hardest
In the USA, the southeastern states are most vulnerable to the costly impacts from human-caused climate change,
Guardian, John Abraham 24 Aug 17 “….. The costs are not uniformly distributed. Some regions will suffer more and other regions will suffer less. In fact, some regions will actually benefit in a warming climate. We understand that the world is interconnected and costs will inevitably be shared to some extent. But it is clear we won’t all suffer the same.

It is also clear that the natural biosystems won’t suffer the same. Some areas are more susceptible to climate change, others less so. Coastal areas and tropical areas are great examples. We know that sea level rise and ocean acidification will impact coastal regions much more than where I live (Minnesota, USA). But tropical zones that experience a very small climate variation throughout the year (there is no winter, for instance, in the tropics) have biosystems that have evolved to survive in very tight climate ranges. The plants and animals just are not used to systematic changes to the climate.

In my opinion, the most interesting research deals with answering just these questions.

Fortunately, a really important paper just came out in Science titled Estimating Economic Damage from Climate Change in the United States. Granted, this paper focused on the United States, but the analysis method and lessons can be applied elsewhere.

So what did they find? First, even in a single country like the United States, the losses will be very uneven. In general, the more southern states will suffer most.  In the figure below, counties are colored by economic consequences from climate change under a business as usual scenario. The time period associated with the image is 2080–2099. Yellow, orange and red colors correspond to climate costs. Green colors are areas where climate change benefits will be seen…..
