Drought Statistics

A single 1°C of warming boosts atmospheric water demand by 7%, while El Niño raises drought risk by 50% in the tropics, pushing drought from a seasonal problem into a global systems shock. You will also see how aerosols have masked trends by 10 to 20% and why, even with early warning and smarter irrigation, drought costs keep climbing, with drought linked losses averaging $9 billion a year from 1990 to 2019.

How We Rate Confidence

Models

Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.

Single source

ChatGPT

Claude

Gemini

Perplexity

Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.

AI consensus: 1 of 4 models agree

Directional

ChatGPT

Claude

Gemini

Perplexity

Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.

AI consensus: 2–3 of 4 models broadly agree

Verified

ChatGPT

Claude

Gemini

Perplexity

All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.

AI consensus: 4 of 4 models fully agree
