CGD Research: CCR Overview
Climate Change Research: Paleoclimate Research
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. This work was supported by the National Science Foundation. (Amman, 2005)

Solar Forcing Indicators
Figure 1. (High resolution image) 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).
