Project Cumulus

Project Cumulus was a 1950s UK government initiative to investigate weather manipulation, in particular through cloud seeding experiments. The project, which was operational between 1949 and 1952, was known jokingly as Operation Witch Doctor. The experiments involved RAF planes dropping chemicals above clouds in an attempt to make rain. A conspiracy theory has circulated claiming that the Lynmouth Flood was caused by Project Cumulus.

Prevention steps

  1. StopNotice a strong emotion (anger, fear, 'they don't want you to know') before you share. Pause first.
  2. Investigate the sourceWho is making the claim, what's their expertise, and what do they gain if you believe it?
  3. Find better coverageRead laterally: open new tabs and see what independent outlets and fact-checkers say.
  4. Trace claims to the originFind the original study, video or document. Check dates and whether quotes are cut.
  5. Ask what would change your mindReal theories can be tested. If every piece of counter-evidence 'proves' the cover-up, it can't be.
  6. Count the peopleBig secret plots need thousands of people to stay silent for years. That rarely happens.
  7. Talk, don't mockWith friends or family, ask questions, listen, share your own sources calmly. Shame backfires.
  8. PrebunkLearn the common tricks (cherry-picking, fake experts, false dilemmas) so you spot them early.
