Russians on the Younger Dryas

At http://elpub.wdcb.ru/journals/rjes/v09/2007ES000250/2.shtml …The Russian Journal of Earth Sciences (2007) had an article, 'Long term solar activity variations in the Pleistocene and their connection with abrupt climate change' … it is interesting that as the role of co2 is increasingly seen to be much less potent than the doomsayers alleged that some scientists are looking to the Sun to explain the dips and peaks in temperature as apparent from ocean sediment cores and isotopes in ice cores etc.
