In short - the emphasis from this statement is extremely misleading: "hundreds of years or even longer for this feedback loop to become effective." The feedback loop will take time to trigger, but the conditions for that feedback loop to be triggered can be locked in before that time. As proof, if we emit a near infinite amount of C02 emissions to produce a run-away hot-house earth, those conditions will be locked in very quickly. In other words, if temperatures rise enough, there won't be enough time (even in a couple hundred years) for them to fall back quickly enough. That's just logic, math & thermodynamics.
