both mathematicians and climate experts will need to communicate with the public, with elected officials, and with the media in a way that emphasizes the robust aspects as well as the uncertainties of climate predictions. They should be frank and forthright about the complexity of the climate system and the limitations inherent in any approximation of it. To the extent possible, they should educate the public to the fact that even the best model will produce a range of possibilities, not a single “forecast for the future.” They should prepare the public to understand that the range of possibilities may change as the models improve and as we get new data about the Earth system. This will not mean that scientists are changing their minds or contradicting themselves; it is part of the normal process of science. The very real uncertainties in the projections of the future should not be allowed to obscure the fact that climate change is occurring and cannot be ignored any longer.Bottom Line: We should all have some notion of how CC modeling works, if only to put our trust in it.
