Abstract:
The Sun’s evolving magnetic field causes variations in solar
irradiance, heliospheric wind, and geospace conditions that range from
seconds-long explosions to billion-year trends. Traces of that
variability can be found in Galileo’s drawings and ancient ice sheets,
while observations of stars like the Sun provide glimpses of what the
Sun did through the ages. This observational material guides us towards
an understanding of the root of solar activity – the dynamo – needed to
understand the Sun-Earth connections.
