Externally forced and internal variability in ensemble climate simulations of the Maunder Minimum
The response of the climate system to natural, external forcing during the Maunder Minimum (ca. A.D. 1645–1715) is investigated using a comprehensive climate model. An ensemble of six transient simulations is produced in order to examine the relative importance of externally forced and internally ge...
