See also the recent Juckes et al 2006 paper Millennial temperature reconstruction intercomparison and evaluation at: (PDF) which reviewed all of the recent literature on palaeoclimatic reconstructions of the temperature history of the last millennium, and which states in its conclusion:

The IPCC2001 conclusion that temperatures of the past millennium are unlikely to have been as warm, at any time prior to the 20th century, as the last decades of the 20th century is supported by subsequent research and by the results obtained here. Papers which claim to refute the IPCC2001 conclusion on the climate of the past millennium have been reviewed and some are found to contain serious flaws. Our study corroborates the IPCC2001 conclusions.

Compare the graph used in the programme with the following graph from the Global Warming Art website at:, which superimposes the results of 10 peer-reviewed studies by separate groups of climate scientists, carried out between 1998 and 2005, of temperatures over the past 1000 years. Although each of the temperature reconstructions below are different, due to the differing calibration methods and data used, they all clearly show that late 20th century temperatures to have been the highest in that 1000 year period:

Reconstructed 1000 yr Temperature

Thus by showing a graph that was a schematic and was not based on data, produced in 1990 when quantitative palaeoclimatology based on real data was in its infancy; and by ignoring all of the peer reviewed research that has been done since then, the programme makers misled the public about the science of the reconstruction of past climate.]
