R EPORTS Solar Forcing of Regional Climate Change During the Maunder Minimum
We examine the climate response to solar irradiance changes between the late 17th-century Maunder Minimum and the late 18th century. Global average temperature changes are small (about 0.3 ° to 0.4°C) in both a climate model and empirical reconstructions. However, regional temperature changes are qu...

Summary: | We examine the climate response to solar irradiance changes between the late 17th-century Maunder Minimum and the late 18th century. Global average temperature changes are small (about 0.3 ° to 0.4°C) in both a climate model and empirical reconstructions. However, regional temperature changes are quite large. In the model, these occur primarily through a forced shift toward the low index state of the Arctic Oscillation/North Atlantic Oscillation as solar irradiance decreases. This leads to colder temperatures over the Northern Hemisphere continents, especially in winter (1 ° to 2°C), in agreement with historical records and proxy data for surface temperatures. 1 |
