I would like to thank Murray Snyder for attempting to contribute to the dialogue on climate change.
However, he would do well to check his math beforehand.
He stated that humans’ contribution to CO2 levels has only been 12 ppm (parts per million).
But if the pre-industrial levels were at 280 ppm and today the level is at 390 ppm, my math says that the difference is 110 ppm, not 12 ppm. Maybe a decimal got missed?
And as for the warmest year on record, even Snyder’s own source said the following: “The warmest 10 years in all three datasets are the same and have all occurred since 1998.” That doesn’t sound like anything to be complacent about.
By the way, the phenomenal warming of 1997-1998 was mostly caused by the strongest El Nino in recorded history. Snyder’s own source also agrees with that.
