A recent study published in the American Meteorological Society’s Journal of Climate has found that the South Asian Summer Monsoon (or SASM) is changing quite dramatically. According to the abstract, the SASM shows: “a clear tendency for weakening SASM circulation and strengthening SASM precipitation during the twenty-first century. These tendencies are consistent, moreover, among multiple realizations for the same model where available.”

Given South Asia’s existing vulnerabilities, and growing U.S. interest in the region, this is a phenomenon to take seriously.
