It was wonderful to see Richard Straw’s excellent letter to the editor in the SCMP today, regarding claims by global warming alarmists. To quote from Mr. Straw:
The chief proponent of anthropogenic global warming is US scientist Michael Mann who, along with a number of colleagues, is famous for his "hockey-stick" temperature graph – the sticky-up bit on his line chart is supposed to represent where global temperatures are today relative to the past several hundred years.
The work of Dr Mann and company underpinned the stance taken by the 2001 United Nations’ Intergovernmental Panel on Climate Change. However, Dr Mann’s studies and conclusions have been formally challenged by scientists and economists (a graph is a graph is a graph, as the South China Morning Post’s very own Jake van der Kamp will tell you) in reputable scientific literature because they have been unable to replicate the numbers.
Of course Dr. Mann has quite a notorious reputation. More information on the hockey stick effect can be found here on John Daly’s website.
