Changes in the intensity of galactic cosmic rays alter the Earth's cloudiness. A recent
experiment has shown how electrons liberated by cosmic rays assist in making aerosols,
the building blocks of cloud condensation nuclei, while anomalous climatic trends in
Antarctica confirm the role of clouds in helping to drive climate change. Variations in
the cosmic-ray influx due to solar magnetic activity account well for climatic fluctuations
on decadal, centennial and millennial timescales. Over longer intervals, the changing
galactic environment of the solar system has had dramatic consequences, including
Snowball Earth episodes.
