manacker: "Solar forcing has played a role in 20th century warming, as many cited studies show."
I asked you this before, manracker, let's try again:
Are you really so obtuse as to believe that anyone here has suggested otherwise?
Nice straw man though.
"The 20th century was a period of unusually high solar activity (highest in 8,000 years according to some studies)."
Right. And per the first study you cited in your long list of them (Solanki 2004):
We stress that solar variability is unlikely to be the prime cause of the strong warming during the last three decades... even under the extreme assumption that the Sun was responsible for all the global warming prior to 1970, at the most 30% of the strong warming since then can be of solar origin.
Got that yet, manacker?
