Climate models project significant drying for the Caribbean

Exacerbation of the 2013–2016 Pan‐Caribbean Drought by Anthropogenic Warming by D.Herrera, CSI member Toby Ault, and colleagues, email: toby.ault@cornell.edu

Climate models project significant drying for the Caribbean as a consequence of increased anthropogenic greenhouse‐gas concentrations. Between 2013 and 2016, virtually the entire region experienced a “Pan‐Caribbean” drought, which was unprecedented since at least 1950. We find that human‐caused warming contributed to ~15–17% of drought severity by increasing evapotranspiration rates, and accounted for ~7% of land area under drought across the Caribbean. Our results therefore suggest that anthropogenic warming has already increased drought risk in the Caribbean.
