An Open Letter to Herb Schultz of Edmonton

Mr. Schultz, 

Recently, The Edmonton Journal published a letter of yours in which you write that the Intergovernmental Panel on Climate Change admits “that there has been zero global warming during the last 17 years, despite a more than doubling of greenhouse gas emissions.” 

Well, here’s something that might surprise you Mr. Schultz: The IPCC did not make such an admission.

In section B.1 Atmosphere of IPCC 2013: Summary for Policy Makers (SPM), the IPCC makes the following statement: “[T]he rate of warming over the past 15 years (1998–2012; 0.05 [–0.05 to 0.15] °C per decade), which begins with a strong El Niño, is smaller than the rate calculated since 1951 (1951–2012; 0.12 [0.08 to 0.14] °C per decade).” (1)

And in the opening of B.1 Atmosphere The Panel make this statement: “Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850.”

Mr. Schultz, if you have any integrity you would retract your statement and apologize to the readers of The Journal for misleading them on a subject as important as climate change. 

In closing allowing me to quote what I believe is the most significant statement of SPM 2013:
“Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased.”
