A pair of papers on the relationship between solar variability and climate have been all the rage in the media and climate wars blogosphere over the last week or so.
The other, by Scafetta and West, came out a day letter and raised questions about whether climate models are understimating the solar contribution. Sadly, it didn’t get much press (It wasn’t in Nature!), but Benny Peiser gave it a good ride, saying that if Scafetta and West are right, it “would present serious trouble for the IPCC.”
So here’s a quiz for readers. Below the fold are quotes from each of the papers. Try to guess which quote is from which paper:
The first is in a figure caption beneath a graph showing the relationship between a solar temperature reconstruction and actual temperature reconstructions over the last 400 years:
Note the good correspondence of the patterns in particular during the pre-industrial era (1600–1900) and the significant discrepancy occurring in the 20th century with a clear surplus warming. (emphasis added)
The second requires no introduction:
The variations measured from spacecraft since 1978 are too small to have contributed appreciably to accelerated global warming over the past 30 years.
No beer for guessing right. This is just a rhetorical question.
