Uncertainty in projections of future climate

While the warming of the climate system through the emission of man-made greenhouse gases is clear from observations, models, and our understanding of the climate system, projections of the future climate face a range of uncertainties. Read more about the most important sources of uncertainty here.

Introducing a model democracy

Using multiple climate models can help to better estimate the uncertainty due to imperfect modeling of the climate system. Read more about how to estimate uncertainty from model projections of future change here.
