Photo of Figure legend: These maps depict change in an index of drought severity for the period 2070-2099 under multiple climate scenarios. The maps show a large variationin potential drought throughout much of the conterminous US, mostly because of high uncertainty in future precipitation. Based on data from the RPA 2020 Assessment, the ‘warm wet’ figure represents a scenario with increased precipitation and less warming resulting from a relatively rapid reduction of greenhouse gases so that emissions peak ~2040. The ‘hot-wet’ scenario, also with rapid reduction of greenhouse gases, is wet but hot. The ‘hot-slightly dry’ scenario assumes continued current emissions levels for much of this century and is hot with slightly less precipitation, while the ‘hot-dry’ scenario is both dry and hot, resulting in the most severe drought conditions.
