`  == although the scientific consensus is that solar variations do not play a major role in determining present-day observed climate change. ==  This appears to be misattributed.  Dr Joanna D. Haigh is not talking about scientific consensus with The Sun and the Earth’s Climate  Someone who cares needs to provide a real link to the ``scientific consensus`` regarding the solar constant to support this claim or this should be removed.   In fact Dr. Haigh writes, ``The absolute radiometerscarried by satellites since the late 1970s have produced indisputable evidence that total solarirradiance varies systematically over the 11-year sunspot cycle, relegating to history the term “solar constant”, but it is difficult to explain how the apparent response to the Sun, seen inmany climate records, can be brought about by these rather small changes in radiation.``  What she's saying is that SOLAR CONSTANT is really an old term and that new technologies are showing that the sun's output is not constant.  Her viewpoint is not reflected here.  How can we be so clumsy in our writing here?  Also, why must AGW theory be peppered into this topic anyway and why is it the leadin?  It's unecessary clumsy and gives a very biased impression of Wikipedia.  If this article is about the solar constant, it should be about the solar constant and if there is a minor tangental interest to AGW theory, we can point to that but to make AGW the centerpiece here is agenda driven.   `
