Multiple Proxy Study Confirms "Global Warming" Skeptic Views - Modern Temps Not Unprecedented, Not Global
From the study itself, and a close review of the above images, we now know the following:
First, as even the New York Times points out, this study determined that the Arctic was warmer during the 1940s to 1970s than during years of the late 20th century. (Sidebar: If the approximate modern instrumental global warming increase of 0.85°C since 1850 is added to the Greenland ice core data, modern warming is still below peaks of the Medieval & Roman periods.) Confirms view of skeptics, check.
Second, the study determined that periods prior to 1000AD had warmer temperatures in Europe. Confirms view of skeptics, check.
Third, this study finds Antarctica was warmer, from the 2nd through 13th centuries, than during our modern era. (Sidebar: If the approximate modern instrumental global warming increase of 0.85°C since 1850 is added to the Vostok ice core data, modern warming is still below the peak temperature between 1AD and 1000AD.) Confirms view of skeptics, check.
Fourth, this study points out that true global warming has not taken place in the modern era, but regional strong warming has. Of the 7 regional areas analyzed, only 3 exhibit a strong warming (more likely only 2, see point #11 below). The other four regions, not so much. Confirms view of skeptics, check.
Fifth, the study clearly indicates that major climate change is taking place at all times, in different manners, across the globe. Climate change is not some new modern phenomenon. Confirms view of skeptics, check.
Sixth, the study shows atmospheric CO2 levels are not a cause of past major climate change. Throughout most of the last 2,000 years, CO2 levels are stable yet climate change is constantly happening. Confirms view of skeptics, check.
Seventh, the study documents that unprecedented regional warming takes place regardless of low/high atmospheric CO2 levels.Confirms view of skeptics, check.
Eighth, this study, in combination with the known recent global temperature trend (subsequent to this study's ending date of 2000AD), clearly makes an indisputable case that recent modern global warming is not as claimed: unprecedented; unequivocal; irrefutable; irreversible; nor dangerously accelerating. Confirms view of skeptics.
Ninth, this study affirms that periods of "unprecedented" warming do not cause the IPCC's urban legend of "runaway," "tipping point," dangerous global warming. Of course, the hottest period ever recorded (Minoan era) in the ice cores over the last 4,000 years already proved that the mythical "tipping point" is just that. Confirms view of skeptics, check.
Tenth, this study again provides proof that the AGW-alarmist researchers will use each and every attempt to remove and/or minimize the exceptional Medieval Warming Period that the vast majority of local/regional paleo research studies, and the historical literature, have well documented. It is simply freaking amazing that this group of researchers would present an analysis of Europe's past warming without the extreme and extended warming of the Medieval era (see chart on right). Confirms view of skeptics, check.
Eleventh, this study clearly proves to the public that the proponents of AGW-alarmism will utilize excessive cherry-picking ofempirical paleo research to fabricate their "scientific" claims of modern "unprecedented" warming. Not only did this study exclude the preponderance of paleo-scientists' research that documents past extreme warming, but this study was brazen enough to include paleotemperature reconstructions that even a peer-reviewed science journal ultimately rejected because of its statistical flim-flam. Without the infamous, widely discredited Gergis et al. study, it is highly likely that the "Australasia" region of the above chart on the left would have to be moved to the chart of the right, above - thus leaving just 2 regions of the world that may have had modern "unprecedented" warming in the 20th century, and only a single region of the world that had "unprecedented" warming since 1970 (recall that this study confirmed the Arctic was warmer from the 1940s to the 1970s). Confirms view of skeptics, check.Conclusion: This multi-cherry-picking proxy study has many claiming that modern temps are the "hottest" across the globe, over the last 1,400 years. In fact, as the above information clarifies, some regions of the world had strong modern warming (that is, supposedly), while the majority did not. As this study itself determines, global warming, cooling and climate change are not done in some lock step manner across the world in a monotonous cause and effect relationship with CO2. Skeptics of both the IPCC's catastrophic global warming hysteria and the elites' CO2-kills fanaticism have pointed this out for years (if not decades). The geological and historical records/datasets support the essentials of the non-hysterical skeptic/lukewarmers' analysis of climate change, and now this study suggests the alarmist community has inadvertently accepted many of the same views.
