The publication Climate Changes and Fish Productivity analyzed three 1500-year temperature proxies including ice cores and tree rings, and found the predominant periodicity of climate fluctuations during the last 1000 years to be ~60 years with the variation from 55-76 years. This same periodicity was also confirmed by other authors.
Given the typical cycle length of ~60 years, the present cycle won't peak until ~2059. BTW, fish stocks of all species studied explodes on the upside every time the planet warms. More good news about GW!
update: another analysis finds a strong 60 year periodicity

Yes - this 60 (maybe 62) year cycle is very important. If valid for surface temperatures (which it seems to be) then IPCC AR4 is debunked. See my site http://earth-climate.com
