Answer:
Climate changes may be linked to changes in the number of dark spots
on the surface of the sun.
Step-by-step explanation:
Solar physicists have shown, using historical data, that sunspot activity correlates very well with climate change occurring on Earth. Consequently, the recent fewer sunspots fits in with the global cooling periods.
Sunspots are formed when strong magnetic fields emerge across the sun's surface, producing holes in the solar corona, solar flares, coronal mass ejections, and changes in the solar wind, a stream of charged particles from the sun.
