      The same GODAS volume averaged across 5°N–5°S, plotted as depth × longitude. Warm tongue = positive anomaly. This is the canonical view forecasters use to read the El Niño Kelvin wave.

      Why this page exists

      Every module on this page tracks a force that, by itself, looks academic — until you stack them. In Singh et al. 2018, a team of climate scientists and the historian Mike Davis showed that the 1877 Great Drought — which killed an estimated 50 million people — was triggered when three of these forces lined up at once.

      In Anderson et al. 2019, ENSO was identified as the only force in the climate system that can synchronize crop failure across continents. The global food system is built on the assumption that distant breadbaskets fail independently. That assumption was tested by 1877 and lost.

      This page surfaces public agency data. It is not a forecast. It is not actionable as an emergency signal. It exists so the public sees the same instruments the agencies do, in one place, with a citation.
