The most severe drought in the instrumental record
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.

Partly verified — Core facts are sourced; some optional detail is deliberately absent.
Climate change, not El Nino, main driver of exceptional drought in highly vulnerable Amazon River Basin
Supports the attribution of the 2023-2024 Amazon drought principally to human-caused climate change rather than to El Nino. V55 verification basis: not retrieved in this session; the study title is given as remembered and the quantified likelihood ratio is deliberately not quoted. A curator should confirm the exact title and figures.
