We used machine<br \/>\nlearning algorithms to derive functions of climatic suitability from a database of georeferenced production locations. Use of several parameter combinations enhances the robustness of our analysis. The resulting multi-model ensemble suggests that higher temperatures<br \/>\nmay reduce yields of <\/span><span class=\"fontstyle2\">C. arabica, <\/span><span class=\"fontstyle0\">while <\/span><span class=\"fontstyle2\">C. canephora <\/span><span class=\"fontstyle0\">could suffer from increasing variability<br \/>\nof intra-seasonal temperatures. Climate change will reduce the global area suitable for coffee<br \/>\nby about 50 % across emission scenarios. Impacts are highest at low latitudes and low<br \/>\naltitudes.
