A new study shows how changes in ocean circulation could reshape global rainfall patterns. A storm reaching California can begin with changes thousands of miles away in the Atlantic Ocean. Climate modeling suggests that as one of the planet’s major ocean circulation systems weakens, more moisture could be directed toward the West Coast while snowfall [...]
