Various climate models show what the future may hold for us on this planet. An important factor is how much carbon dioxide the ocean can absorb without having too great an impact on the climate. New research now shows that if fish and plankton are included in the models, the results will be completely different from previous calculations. Quite simply, the impact of marine animals on the ocean has been excluded in the past. And since we are currently fishing our oceans to extinction, this fact could have devastating consequences – on the climate.
