IPCC Report Leaked…contains game-changing admission of enhanced solar forcing

Lead story from the Second Order Draft: strong evidence for solar forcing beyond TSI now acknowledged by IPCC

Compared to the First Order Draft, the SOD now adds the following sentence, indicated in bold (page 7-43, lines 1-5, emphasis added):

Many empirical relationships have been reported between GCR or cosmogenic isotope archives and some aspects of the climate system (e.g., Bond et al., 2001; Dengel et al., 2009; Ram and Stolz, 1999). The forcing from changes in total solar irradiance alone does not seem to account for these observations, implying the existence of an amplifying mechanism such as the hypothesized GCR-cloud link. We focus here on observed relationships between GCR and aerosol and cloud properties.

The Chapter 7 authors are admitting strong evidence (“many empirical relationships”) for enhanced solar forcing (forcing beyond total solar irradiance, or TSI), even if they don’t know what the mechanism is. This directly undercuts the main premise of the report, as stated in Chapter 8 (page 8-4, lines 54-57):

There is very high confidence that natural forcing is a small fraction of the anthropogenic forcing. In particular, over the past three decades (since 1980), robust evidence from satellite observations of the TSI and volcanic aerosols demonstrate a near-zero (–0.04 W m–2) change in the natural forcing compared to the anthropogenic AF increase of ~1.0 ± 0.3 W m–2.

The Chapter 8 authors (a different group than the Chapter 7 authors) are explicit here that their claim about natural forcing being small compared to anthropogenic forcing is based on an analysis in which the only solar forcing that is taken into account is TSI. This can be verified from the radiative forcing table on page 8-39 where the only solar variable included in the IPCC’s computer models is seen to be “solar irradiance.”

This analysis, where post-1980 warming gets attributed to the human release of CO2 on the grounds that it cannot be attributed to solar irradiance, cannot stand in the face of the Chapter 7 admission of substantial evidence for solar forcing beyond solar irradiance. Once the evidence for enhanced solar forcing is taken into account we can have no confidence that natural forcing is small compared to anthropogenic forcing.

The Chapter 8 premise that natural forcing is relatively small leads directly to the main conclusion of the entire report, stated in the first sentence of the Executive Summary (the very first sentence of the entire report): that advances since AR4 “further strengthen the basis for human activities being the primary driver in climate change” (p.1-2, lines 3-5). This headline conclusion is a direct descendant of the assumption that the only solar forcing is TSI, a claim that their own report no longer accepts.

Love this comment:

I’m going to have to stop reading Ch11 because it is just making me angry. The manipulation and deception is beyond belief. In between the paragraphs so convoluted that they are meaningless, there are outrageous gems such as this one:

“It is virtually certain that globally-averaged surface and upper ocean (top 700m) temperatures averaged over 2016–2035 will be warmer than those averaged over 1986–2005.”


Since it is already warmer NOW than it was over the average of 1986 to 2005, the temperature could flat line from now to 2035 and that would still be true! In fact, the temperature could DECLINE from now until 2035 and that might still be true.

Notice also that they cleverly left a gap between the end of one period (2005) and the beginning of the next period (2016)? Eliminates the falling temps we’ve seen since 2005 until now! They’re hoping that their precious warming resumes by 2016 and this cooling period is then excluded from the data that would support the statement!

I’m not even done the first 5 pages and I’ve shouted b*llsh*t out loud a dozen times already.
