CALGARY, April 17, 2014 /CNW/ - Friends of Science has issued a statement dismissing the conclusions of Shaun Lovejoy's most recent paper published in Climate Dynamics April 6, 2014, saying the methodology is faulty and that Lovejoy excludes known periods where the earth naturally warmed, long before human use of fossil fuels.
"This paper relies on the discredited "Hockey Stick" graph, that even the Intergovernmental Panel on Climate Change (IPCC) do not use anymore," says Ken Gregory, director of research for Friends of Science.
"Lovejoy makes simplistic correlations between carbon dioxide levels and warming, without accounting for the increased solar activity in that time period. The sun is the sole energy source of earth; its effect cannot be discounted. Likewise he only refers to proxies from the 1500 year time frame, when there are complete temperature records from Central England available between January 1663 and December 1762 that show a warming of 0.90 degrees C. This was long before industrial activity. Only natural factors caused this warming; Lovejoy does not address this flaw in his thesis."
Friends of Science are also calling up the Chancellor of McGill University to retract the McGill press release and issue an apology for the use of Lovejoy's quote ""This study will be a blow to any remaining climate-change deniers..."
"This is not the language of science or good taste that one expects from a Nobel Laureate university," says Gregory.
Friends of Science have spent a decade reviewing a broad spectrum of literature on climate change and have concluded the sun is the main driver of climate change, not carbon dioxide (CO2). The core group of the Friends of Science is made up of retired earth and atmospheric scientists.
