Impacts of sunspots on climate change

Sunspots are the coldest part of the Sun, and usually develop in pairs. The magnetic field in sunspots stores energy that is released in solar flares/CMEs. As a result, solar source activities usually occur in a cycle that mimics the 11-year sunspot cycle. The solar energy that drives the weather system, scientists naturally wondered whether they might connect climate changes with solar variations. The Sun is the primary source of our space weather. Storms on the Sun, in the form of solar flares/coronal mass ejections, can launch showers of radiation and powerful magnetic fields into interplanetary space. Space weather comes as short-lived storms which can last minutes to hours to days. The Sun also undergoes cycles in its level of activity that span years to decades, causing longer-term variations in space weather. Finally, the Sun has changed substantially over the multi-billion year history of our solar system, producing long-term "climate change" effects in our space weather.
