      abstract = {This paper is, to our knowledge, the first paper in  climate economics to consider the combination of spatial  heat transport and polar amplification. We simplified the  problem by stratifying the Earth into latitude belts and  assuming, as in North et al. (1981), that the two  hemispheres were symmetric. Our results suggest that it is  possible to build climate economic models that include the  very real climatic phenomena of heat transport and polar  amplification and still maintain analytical tractability.  We derive optimal fossil fuel paths under heat transport  with and without polar amplification. We show that the  optimal tax function depends not only on the distribution  of welfare weights but also on the distribution of  population across latitudes, the distribution of marginal  damages across latitudes and cross latitude in-
teractions  of marginal damages, and climate dynamics. We also  determine optimal taxes per unit of emission and show that,  in contrast to the standard results suggesting spatially  uniform emission taxes, poorer latitudes should be taxed  less per unit emissions than richer latitudes.},
