This note is in reference to Michael Ivey’s letter “Carbon Dioxide Does Not Cause Global Warming” [Dec. 25 Xpress]. Mr. Ivey states, “Even the Intergovernmental Panel on Climate Change admits that there has been no warming over the last 16 years.”
Please see the excerpt below, from the report “Climate Change 2013: The physical science basis working group 1 contribution to the IPCC fifth assessment report.” The IPCC is the Intergovernmental Panel on Climate Change that was mentioned. I thought people might want to see the actual data.
Fig. SPM. 1a, Anomaly (C) relative to 1961-1990:
“Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850. In the Northern Hemisphere, 1983-2012 was likely the warmest 30-year period of the last 1400 years (medium confidence).”
