What is the likely impact of increased solar output on global temperatures?

Increased solar output would likely lead to a rise in average global temperatures due to the direct relationship between the amount of solar energy received by the Earth and the resulting thermal energy absorbed by the atmosphere and surface. When solar output increases, more energy reaches the Earth, leading to greater heating. This is fundamentally because the Earth’s climate system relies on a balance of incoming solar radiation and outgoing heat emission, and an increase in solar energy disrupts that balance favoring higher temperatures.

The thermal response of the atmosphere and oceans to this increase would not be uniform across the globe, but overall, the net effect would lead to an increase in global temperatures. Scientists can observe historical trends where periods of heightened solar activity have been associated with warming phases. Consequently, the relationship between solar output and global temperatures supports the idea that additional solar energy would likely contribute to an increase in temperatures on a planetary scale.
