The 20th century warming is not unusual, Says Dr. Sallie Baliunas and Dr. Willie Soon from the harvard.
They have conducted a resarch that once and for all confirms that the climate globally have had swings up and down for the last 10.000 years. Of special interest is the claim that the MWP from year 900 to 1300 was warmer than today….
Sallie Baliunas has along with her colleagues, Harvard astrophysicists Dr. Willie Soon and Dr. David Legates, in strong terms criticised the validity of the “hockey stick” by Michael Mann. The hockey stick were for many years the icon of manmade global warming. The pilar that the arguments were standing on. Michael Mann argued that the warming in the last 100 years were unpresidented and it was 98% likely that humans were to blame. His temperature grapfh completely deleted the Medieval Warm period and the Little Ice Age. But Baliunas and Soon and his colleagues refuted these claims in a now famous article from 2003:
RECONSTRUCTING CLIMATIC AND ENVIRONMENTAL CHANGES OF THE PAST 1000 YEARS: A REAPPRAISAL
Part of the conclusion goes like this:
“After examining more than 240 individual proxy records analyzed by nearly 1000 researchers, we concluded that taken individually, proxy records offer strong support for the widespread existence of both a Medieval Warm Period (~A.D. 800 to 1300) and a Little Ice Age (~A.D. 1400 to 1850), undermining Mann’s conclusion that the climate of the 20th Century was unusual when compared to the variability over the last millennium. (Proxy records are secondary or inferred sources from which assumptions about air temperature may be drawn).” Find the full .pdf article here.
