Claim: Ljungqvist's millennial temperature reconstruction was very similar to Moberg et al.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Ljungqvist's 2,000 year extratropical Northern Hemisphere reconstruction generally agreed well with Mann et al.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A 2,000 year extratropical Northern Hemisphere reconstruction by Ljungqvist published by Geografiska Annaler in September 2010 drew on additional proxy evidence to show both a Roman Warm Period and a Medieval Warm Period with decadal mean temperatures reaching or exceeding the reference 1961–1990 mean temperature level.

Passage: Its main findings were; 20th century instrumentally measured warming showed in observational evidence, and can be simulated with climate models, large-scale surface temperature reconstructions "yield a generally consistent picture of temperature trends during the preceding millennium", including the Medieval Warm Period and the Little Ice Age, "but the exact timing and duration of warm periods may have varied from region to region, and the magnitude and geographic extent of the warmth are uncertain."

Passage: The application of alkenone paleothermometers to high-resolution paleotemperature reconstructions of older glacial terminations have found that very similar, Younger Dryas-like paleoclimatic oscillations occurred during Terminations II and IV.

Passage: The third assessment report (TAR) prominently featured a graph labeled "Millennial Northern Hemisphere temperature reconstruction" based on a 1999 paper by Michael E. Mann, Raymond S. Bradley and Malcolm K. Hughes (MBH99), which has been referred to as the "hockey stick graph".

Passage: The 2007 IPCC Fourth Assessment Report cited 14 reconstructions, 10 of which covered 1,000 years or longer, to support its conclusion that "Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher than during any other 50-year period in the last 500 years and likely the highest in at least the past 1,300 years".

Passage: published on 10 February 2005 used a wavelet transform technique to reconstruct Northern Hemisphere temperatures over the last 2,000 years, combining low-resolution proxy data such as lake and ocean sediments for century-scale or longer changes, with tree ring proxies only used for annual to decadal resolution.
