Do sunspots cause climate change?
Some people wonder if the reason the sea ice is declining and the planet is warming can be explained by sunspots, which are related to variations in the Sun’s energy output over time. While changes in the suns output can affect the Earth’s climate, the recent warming cannot be explained by changes in solar activity.
