The recent trend of a .05 percent per
decade increase in Total Solar Irradiance (TSI) in watts per meter
squared, or the amount of solar energy that falls upon a square meter
outside the Earths atmosphere. The trend was measured between successive
solar minima that occur approximately every 11 years. At the bottom, the
timeline of the many different datasets that contributed to this finding,
from 1978 to present.
Please notice that the low point in the most
recent cycle is noticeably higher than that of the previous cycle.
