Verified answers

Most of the atlas helps you find data. This page answers questions — and shows its work. Two methods so far: a Before-After-Control-Impact deforestation analysis, and regional climate trends from ERA5 — each with significance, uncertainty, full provenance, nulls reported as nulls, and ill-posed questions refused rather than guessed.

① Deforestation · Before-After-Control-Impact

Before-After-Control-Impact on Hansen forest loss × impact variable; controls remove the regional trend. Observational evidence, not a causal prediction. · deforestation analog (BACI). Answers “Is deforestation happening here, and what are its effects?”

Rondônia, Brazil

Amazon 'arc of deforestation' — rainforest → cattle pasture forest lost 2005–2008 before 2001–2004 → after 2015–2020

●Measured signal — the trustworthy variables changed in the expected direction.

The trustworthy local signals agree with the deforestation signature: land surface temperature warmer; greenness ndvi less green. Regional/coarse variables (rainfall, wind, humidity) are directional hints at best; soil moisture is model-based and reported without a consistency verdict. Weight the strong tier; treat the rest as context.

Observational analog (a natural experiment over comparable places) — evidence, not a prediction for any one spot. Each bar shows the change versus the natural jitter between undisturbed control pixels; it must clear the ┊ tick to count as a real signal.
