Global Warming Will Drive Vast, Unpredictable Shift in Natural Wealth

Many studies have shown that critical natural resources, including fish stocks, are moving poleward as the planet warms. A new Yale-led study suggests that these biophysical changes are also reallocating global wealth in unpredictable, and potentially destabilizing, ways.

On its surface, these biophysical movements will shift resources from communities and nations closer to the equator into places closer to the poles. In many cases this would seem to exacerbate inequalities between richer and poorer communities.

But writing in the journal Nature Climate Change, the researchers suggest that the impacts on net global wealth may not be that straightforward. In fact, they make the case that changes are more likely than not to produce an overall net loss in global wealth.
