Project Summary

What do rising sea levels, depletion of the ozone layer, retreating glaciers and Al Gore's comeback have in common? As global warming becomes more hot button, there's a need to know how much the sun and space weather affect our climate. My project, overseen by Dibyendu Nandi, explores the relationship between sunspots, cosmic rays, Total Solar Irradiance (TSI) and Global temperature. Reconstructions of cosmic rays and TSI were made by a sunspot proxy dating back to 1610. Trends of the reconstructions and global temperature were made and analyzed to discover how much the Sun is contributing to the recent rise in global temperature.
