Editor Note: In October 2017 (15 months ago), Joe Romm at ThinkProgress published a post, September  sets alarming global temperature record and negates a favorite denier talking point.
In his words:
September 2017 smashed multiple climate records, alarming scientists and further negating a favorite talking point of climate science deniers…. It’s especially remarkable to see these records in the UAH satellite data….
“The signal of global warming has become so dominant that even the deniers’ own favorite cherry-picked datasets clearly now show it,” climatologist Michael Mann told ThinkProgress. For those who live in the world of real scientific analysis, rather than conservative talking points, satellite data, ground-based weather stations, sea-based buoys, and even weather balloons all reveal a steady long-term warming trend.
Mann added, “even the questionable UAH satellite record, which has historically underestimated the rate of global warming as a result of serial mathematical errors, can no longer obscure the anomalous warming of the planet.”
By e-mail, Dr. Romm was invited to update his analysis on recent monthly temperatures in light of the ‘global lukewarming’ position. His response follows:
