	Figure. Solar Forcing Indicators and NCAR-CSM 1.4 simulation with full forcing. ~207-year Derives-band component of the global surface temperature in a fully forced climate simulation is compared to sunspot observations (group sunspot numbers), the radio-nucleides of 10Beryllium and 14Carbon, as well as indications of observed increased aurora activity at high northern latitudes (triangles). High resolution figure.

Fingerprint of Solar Influence on Past Millennium Climate

Simulations with a fully coupled Climate System Model are used to show that a temporal fingerprint of solar influence on climate can be isolated. Smaller, rather than larger amplitudes of solar irradiance changes over the past Millennium generate a climate response in better agreement with proxy-based climate reconstructions.
