Incoming Sunlight
Graph Summary
Total incoming sunlight each year based on sunspot observations since 1610. The Sun's brightness does change over time, but none of the observed changes are large enough to account for global warming. Data from NOAA NCEI.
Image Summary
Images of the Sun in filtered visible light on February 28, 2014 (left), near solar maximum, and on February 18, 2020 (right), near solar minimum. Overall, faculae generally outshine dimming caused by sunspots. Images from NASA SDO.

Reconstruction of total solar irradiance based on sunspot observations since the 1600s. During strong solar cycles, the Sun's total average brightness varies by up to 1 Watt per square meter. Changes in the Sun's overall brightness since the pre-industrial period have been minimal, making a very small contribution to global-scale warming. NOAA Climate.gov image, based on the Climate Data Record by Coddington, et al., 2016.

Intensitygrams—images of the Sun in filtered visible light—based on data from NASA's Solar Dynamics Observatory telescope on February 28, 2014, (left), near the maximum of the last solar cycle, and on February 18, 2020 (right), near the solar minimum. Dark patches called sunspots are easier to see than their companion faculae, diffuse bright areas that contribute to making the Sun slightly brighter during solar maximum. Images from NASA SDO.
