While CMIP5 model robustly project drying of the eastern Mediterranean by the end of the century, the magnitude of this drying varies widely, with some models showing mild drying and others showing drying of more than 50%. The factors explaining this spread are explored in 42 CMIP5 models. It is found that about half of this spread is related to large-scale drivers of climate variability such as Hadley Cell widening, Arctic amplification, stabilization of the tropical upper troposphere, or changes in the Arctic stratosphere. Much of the rest of the spread is associated with local conditions such as variations in relative humidity and in the eastern-Mediterranean storm track. However, the relative contributions of local factors vary strongly by location.
