Is there a 66-year cycle in temperatures?

If the (approximate or strict) 66-year cycle is real, we may be entering - or we may have entered - a similar warming-free period as the period from the 1940s to the 1970s. Ocean cycles linked to the Atlantic Ocean - and perhaps the Pacific Ocean - would be the most likely explanations if the 66-year cycle were real. Knudsen et al. 2011, a paper discussed by Tamino, seems to be much less conclusive when it comes the value of the maximally likely periodicity.
