The above is from an article posted on the Watt's Up With That? blog and is a quick overview of an academic paper published in Quaternary Science Reviews. The authors state as part of their conclusion:
Within the limit of chronological uncertainties, some (but not all) of these cooling events at Moose Lake coincide with periods of reduced solar irradiance, such as the solar minima centered on the middle and late LIA [Little Ice Age] (250 and 100 cal BP [before present]), 1400 cal BP, and 3400 cal BP (Steinhilber et al., 2009).But they refuse to extend this to make conclusions about "anthropogenic global warming". Yep, it is a career-killer if you go against the gospel that CO2 is cooking the planet. Only if you are a retired scientist or a non-academic can you dare go against the enforced "consensus" of global warming. Hopefully, someday soon the fanatics will lost control over "the science" and real science will again blossom in the field of climate science.
