Study published in Geophysical Research Letters disputes the hockey stick conclusions

While Mann claims his hockey stick science to be “vindicated”, we have this from World Climate Report, a new peer reviewed study that illustrates that the current warm period we live in is neither unique nor unprecedented. They also manage to point out the key issue, the uncertainty of proxies such as used by Mann et al. – Anthony We constantly hear that the warmest years on record have all occurred in the most recent decades, and of course, we are led to believe this must be a result of the ongoing buildup of greenhouse gases. In most places, we have approximately 100 years of reliable temperature records, and we wonder if the warmth of the most recent decades is unusual, part of some cyclical behavior of the climate system, or a warm-up on the heels of a cold period at the beginning of the record. A recent article in Geophysical Research Letters has an intriguing title suggesting a 2,000 year temperature record now exists for China – we definitely wanted to see these results of this one.
