A network of interdisciplinary scholars studying past climate change
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.
