The most severe drought in the instrumental record

node

An El Nino coinciding with record tropical North Atlantic warmth produces drought across two consecutive dry seasons. The Rio Negro at Manaus falls below its previous record low in October 2023 and lower again in October 2024. River transport fails over large areas, and lethal water temperatures in a middle-Amazon lake kill river dolphins in numbers. Rapid attribution analysis concludes that climate change rather than El Nino was the dominant driver.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
