Land changes in both directions at once. SCOPE reports every type it measured, not only the one that makes the better headline.

How sure is this?

The strongest area (#1) has 89% confidence. It appears in 5 of 6 later clear images, so it is not a one-day artefact. Radar confirmed some of these areas; the others rest on optical and seasonal evidence. Confidence measures how strong the evidence for real surface change is; it does not identify the cause or who did it.

How it was measured

SCOPE used Sentinel-2 optical imagery at 10 m, cloud-masked and combined over each period, Sentinel-1 radar as an independent check , and the same season in earlier years so normal seasonal change is not reported as real change. The analysis took 25 seconds.
