The 'hockey-stick' pseudo science that the IPCC attempted to fool the public with takes another hit - a new study concerning East China Sea temperatures confirms the known global warming science facts - unprecedented ocean temperatures were prior to modern era

Read here. The IPCC's known political agenda requires it to publish "science" that purportedly establishes modern warming as unprecedented. One of the results of this agenda was the infamous and now discredited study known as the 'hockey stick'.
Unfortunately for the IPCC, the vast majority of scientific research confirms that ancient and historical global/regional temperatures do not resemble a hockey-stick with modern warming being higher than earlier periods. And now new Chinese research by Wu et al. has determined the same - there is no hockey-stick.
"The East China Sea SST reconstruction was developed by 5 researchers with various affiliations with several Chinese universities...collected a sediment core from the sea floor in the Southern Okinawa Trough (SOT) over which the warm Kuroshio current flows...The researchers analyzed the top 10 meters of the sediment core, corresponding to 2,700 years of sedimentation and from it were able to resolve 25-yr averages...shows a significant degree of long-term temperature variability...were able to identify the well-recognized climate periods of the past several millennia, including the Little Ice Age (LIA), Medieval Warm Period (MWP), Sui-Tang dynasty Warm Period (STWP), Dark Age Cool Period (DACP), and the Roman Warm period (RWP) along with the Current Warm Period (CWP) beginning in the mid-19th century...the temperatures at the end of the Current Warm period (CWP), are not the highest of the entire reconstruction. In fact, there are indications that there were 25-yr periods during nearly all of the previously identified warm periods in which the reconstructed temperature exceeded the recent average." [Weichao Wu, Wenbing Tan, Liping Zhou, Huan Yang, Yunping Xu 2012: Geophysical Research Letters]
Conclusions: The actual global warming science facts are again confirmed by the newest research. The IPCC's discredited 'hockey stick' was indeed bogus science. Unprecedented ocean temperatures (and regional/global) occurred prior to the modern era of growing consumer/industrial CO2 emissions.
