Uncertainty makes action more important

Researchers have concluded that the argument that action on climate change should wait for greater scientific certainty is misguided, and uncertainty should instead be a strong incentive to take action. While planning for a known future condition is relatively simple, uncertainty associated with climate change means a wider range of future outcomes and thus a greater likelihood of exceeding ‘safe’ limits. The researchers conclude that decision-makers need to consider responses to this range, including the extremes.
