New Reconstruction of Regional and Global Temperatures for the Past 11,300 Years

marcott 13

A new global multiproxy reconstruction finds that while the first decade of the 20th century was among the cold 5% since the start of the Holocene, current temperatures are among the highest in 5000 years.  The study by Shaun Marcott et al., published here in Science, largely confirms the earlier reconstructions of Mann et al. for the past two millennia.  For the benefit of climate historians, the authors also find a distinct Medieval Warm and Little Ice Age in their reconstructions.

    Mann et al (1999) has its mean and the vast bulk of its confidence intervals below 0 up until the 20th century. This reconstruction is the opposite. In fact, most of its mean does not fall within the Mann et al (1999) confidence intervals. This does not confirm, but rather contradicts Mann et al.
