Climate scientists could help convince skeptics by correctly predicting future events. Skeptics could vet the predictions immediately to avoid late refutations. They’d look foolish if they tried to downplay the events if they didn’t raise concerns at the time they were predicted.
Looking fairly at things, predictions along the lines of ‘An inconvenient truth’ did not help. ( A UK high court ruling found at least 9 errors or exaggerations in the film. )
Demonstrating predictability should increase acceptance.
