How sure is this?
The strongest area (#1) has 98% confidence. It appears in 6 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. Compared with the same season in earlier years, this is clearly unusual. 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, which sees through cloud, as an independent check; the same season in 2021, 2020, so normal seasonal change is not reported as real change. The whole analysis took 11 seconds.
