A Stellar View on Solar Variations and Climate

摘要

The global warming observed over the past century has been attributed to both natural and human forcings (7). One of the natural forcings may be variations in solar activity, which appear to be correlated with climate change (2). Climate models have used reconstructions of solar irradiance to reproduce important aspects of past global warming (3). However, recent studies of Sun-like stars call for a reevaluation of the influence of solar activity variations on climate.
