摘要：In response to a request from the U.S. Congress, the U.S. National Research Council (NRC) assembled a committee to describe and assess scientifi c efforts to reconstruct surface temperature records for the Earth over the last 2000 years. This research, and especially the reconstructions originally published by Mann et al. (1998, 1999) and featured in the Intergovernmental Panel on Climate Change Third Assessment Report (2001), attracted considerable attention because the authors concluded that the Northern Hemisphere was likely warmer during the late 20th century than at any other time during the past millennium. Controversy arose because many people interpreted this result as defi nitive evidence of anthropogenic causes of recent climate change, while others criticized the methodologies and data that were used. The NRC committee’s report (2006) attempts to diffuse this controversy by providing a comprehensive assessment of surface temperature reconstructions for the last 2000 years, as well as the implications of these efforts for our understanding of global climate change.
