Decadal Cycles in the Sun, Sun-like Stars,
and Earth's Climate System


This workshop will facilitate our quest for a deeper understanding of solar cycle variations, Sun-like star variability, solar influences on climate change, and decadal climate variations. This workshop is especially timely as we anticipate an upcoming solar cycle that will likely differ significantly from the past three cycles.

Sessions are organized around the following science questions:

  • What can we learn about decadal climate response and climate sensitivity using the solar cycle as a well-specified external radiative forcing?
  • What is current understanding of the amplitude of solar spectral variability and the response of the Earth’s atmosphere and climate system?
  • How does total solar irradiance vary over the solar cycle and what are the implications for climate modeling to recent refinements in its magnitude?
  • How do comparisons with Sun-like stars improve our understanding of solar variability?
  • How can solar and climate models be advanced to better reproduce decadal variability and improve forecast capabilities?

The sessions planned are:

  1. Solar Irradiance Cycles
  2. Comparative Sun-Star Cycles
  3. Climate Sensitivity and Global Energy Imbalance
  4. Climate System Decadal Variability
  5. Modeling and Forecasting Solar Cycles and Climate Impacts

This workshop is jointly sponsored as the 8th Solar Radiation and Climate Experiment (SORCE) Science Team Meeting and the 1st NASA GSFC / CU LASP Sun Climate Research Center (SCRC) Symposium.  Since its launch in January 2003, SORCE has been measuring total solar irradiance (TSI) and solar spectral irradiance (SSI), which are part of NASA Earth Observing System’s 24 key observables.  SORCE Meetings bring together interested members of the broad science community to discuss current understanding of solar variability and the Sun's influence on climate and global change.  The recently formed NASA GSFC / CU LASP Sun Climate Research Center also shares this goal and is a co-sponsors for this workshop. 

The format for this workshop consists of invited and contributed presentations. We encourage your participation and hope that you will share this announcement with colleagues.
