IPCC leaked report, enhanced solar forcing

[Guest]

The total solar flux which reaches the surface of the earth averaged over the seasons and the dinurial cycle is approx 680 W/m2. Over the period from the Maunder minimum the total solar variability (over all wavelengths) has been 1.5W/m2 which represents about 0.18% variation over a period of over 150years. This forcing is over that full time period. Put into simple terms, at the end of the Maunder minima (150 years ago) the solar output was 680W/m2, and now it is 681.25W/m2.

Remember that what is really important here is that all of the energy should normally escape back to space leaving a zero net radiative forcing. The actual magnitude of the suns energy input is not overly significant.

The Greenhouse gas forcing is a measure of the imbalance we have introduced into that natural equalibrium, such that on a constant basis the sun is accumulating 0.32W/m2 of extra energy into the system. This forcing is constant and happening on a second by second basis. Greenhouse gas forcing is a measure of the instantanious radiative budget imbalance.

This is the context of why the solar contribution to the warming of the planet is relatively insignificant.

This is what I am talking about when I say that skeptics are unable to account for the imbalance in the top of the atmosphere radiative budget.
