If science can't explain some part of how a system works, science cant make predictions about that system. It's nonsense.

Science makes predictions that turn out to be true on incomplete theories and systems all the time. Even if we're missing causes for sinks we can make predictions on what happens when there's more greenhouse gases in the atmosphere as the effect of them are well understood.
