«A peer - reviewed paper [Krivova et al.] published in the Journal
of Geophysical
Research finds that reconstructions
of total solar irradiance (TSI) show a significant increase since the Maunder minimum in the 1600's during the Little
Ice Age and shows further increases over the 19th and 20th centuries... Use
of the Stefan - Boltzmann equation indicates that a 1.25 W / m2 increase in solar activity could account for an approximate.44 C global temperature increase... A significant new finding is that portions
of the more energetic ultraviolet region
of the solar spectrum increased by almost 50 % over the 400 years since the Maunder minimum... This is highly significant because the UV portion
of the solar spectrum is the most important for heating
of the oceans due to the greatest penetration beyond the surface and highest energy levels.
