Coss Posted January 6, 2015 Report Share Posted January 6, 2015 Hottest year ever? Giant clam reveals Middle Ages were warmer than today Anthony Watts / 1 day ago January 5, 2015 While government science and media begin the ramp-up to claim 2014 as the “hottest year ever†China’s Sea’s biggest bivalve shows that the Middle Ages were warmer than today, when Carbon Dioxide was lower. From the Chinese Academy of Sciences: Two recent papers, one is in Earth-Science Reviews and the other is in Chinese Science Bulletin, have studied key chemical contents in micro-drilled giant clams shells and coral samples to demonstrate that in the South China Sea the warm period of the Middle Ages was warmer than the present. The scientists examined surveys of the ratio of strontium to calcium content and heavy oxygen isotopes, both are sensitive recorders of sea surface temperatures past and present. The aragonite bicarbonate of the Tridacna gigas clam-shell is so fine-grained that daily growth-lines are exposed by micro-drilling with an exceptionally fine drill-bit, allowing an exceptionally detailed time-series of sea-temperature changes to be compiled – a feat of detection worthy of Sherlock Holmes himself. By using overlaps between successive generations of giant clams and corals, the three scientists – Hong Yan of the Institute of Earth Environment, Chinese Academy of Sciences, Willie Soon of the Harvard-Smithsonian Center for Astrophysics and Yuhong Wang of Fudan University, Shanghai – reconstructed a record of sea-surface temperature changes going back 2500 years. The Roman and Mediaeval Warm Periods both showed up prominently in the western Pacific and East Asia. Sea surface temperatures varied considerably over the 2500-year period. Changing patterns of winter and summer temperature variation were also detected, disproving the notion that until the warming of the 20th century there had been little change in global temperatures for at least 1000 years, and confirming that – at least in the South China Sea – there is nothing exceptional about today’s temperatures. Dr. Yan said: “This new paper adds further material to the substantial body of real-world proxy evidence establishing that today’s global temperature is within natural ranges of past changes.†Dr. Soon added: “The UN’s climate panel should never have trusted the claim that the medieval warm period was mainly a European phenomenon. It was clearly warm in South China Sea too.†Link to comment Share on other sites More sharing options...
YimSiam Posted January 7, 2015 Report Share Posted January 7, 2015 I figured the "giant clam" in question, with its revelations of unwanted truths of bygone eras, was almost certainly some pussy from Patpong. YimSiam Link to comment Share on other sites More sharing options...
Flashermac Posted January 7, 2015 Report Share Posted January 7, 2015 The Vikings are said to have left North America because the climate suddenly started getting cooler. At least that's what the settlement at L'anse aux Meadows seems to show. Link to comment Share on other sites More sharing options...
