THE HOCKEY SCHTICK: New paper finds a significant increase of solar energy at Earth's surface from 1979-2011
A paper published today in Atmospheric Chemistry and Physics finds a significant increase of solar energy reaching the Earth's surface over the period from 1979-2011. According to the authors, the observed global brightening "corresponds to an increase of 2.7 W m−2 of solar energy reaching the Earth's surface and an increase of 1.4% or 2.3 W m−2 absorbed by the surface, which is partially offset by increased longwave cooling [from 'greenhouse' gases] to space." By way of comparison, the alleged increase of radiative forcing from CO2 during the same time period is 0.8* W m-2, 70% less than the effect of global brightening. As noted by Dr. Roy Spencer, a 1-2% change in solar energy received at Earth's surface can alone account for global warming - or global cooling.
Climate: The sun's role is important, but it's just a cameo | Carbon Brief
Speaking on BBC Radio 4's Life Scientific programme yesterday, atmospheric physicist Professor Joanna Haigh says the amount of energy given off by the sun can affect earth's temperature in small but significant way. Relative to the effect of greenhouse gas emissions, however, the sun's role in climate change is limited, she explains.
