Short summary
                    We explore the long-term dynamics of Earth's climate and carbon cycles under a pair of contrasting scenarios to the year 2300 using six models that include both climate and carbon cycle dynamics. One scenario assumes very high emissions, while the second assumes a peak in emissions, followed by rapid declines to net negative emissions.  We show that the models generally agree that warming is roughly proportional to carbon emissions but that many other aspects of the model projections differ.
