Climate in the 21st Century

Climate justice accounts for the most challenging global governance goal. In the current post- COP21 Paris agreement climate change mitigation and adaptation efforts, the financialization of the ambitious goals has leveraged into a blatant demand. In the weighting of the burden of global warming, the benefits of a warming earth have been neglected since recently. Following the introduction of the gains from climate change (Puaschunder 2017), this article proposes a model to distribute the benefits of a warming earth in a fair way based on which countries are losing and which countries are winning from a warming earth until 2100. A macroeconomic cost-benefit analysis thereby aids to find the optimum solution on how to distribute climate change benefits and burden within society. When unidimensionally focusing on estimated GDP growth given a warmer temperature, over all calculated models assuming linear, prospect or hyperbolic gains and losses, the world will be gaining more than losing from a warming earth until 2100. Based on the WL index of 188 countries of the world, less countries (n=78) will gain more from global warming until 2100 than more countries (n=111) will lose from a warming earth. Based on the overall WLTT index factored by GDP per inhabitant, global warming benefits are demanded to be redistributed in a fair way to offset the costs of climate change loser countries for climate change mitigation and adaptation efforts and to instigate a transition into renewable energy
