Responding to the CO2 Coalition's "Fact #11" on Mountain Glacier Melting
CO2 Coalition 's " Fact #11 " (together with " Fact #12 ") claim that a "tipping point" occurred in 1800 that caused mountain glaciers to melt (and sea levels to rise), and since this "tipping point" occurred before major increases in CO2, both the glacial melting and sea level rise "are directly the result of the natural warming that began in the late 17th-century." They assert that glacial retreat (and sea level rise) "continues at about the same rate today as it was 150 years ago." The graph they use to support this claim was taken from Oerlemans 2005[1] with their own annotations. The paper they reference is pretty interesting, though there is absolutely no claim in the paper of any "tipping point" in 1800, and the "190-year trend of glacier shortening" is an annotation of CO2 Coalition, not a claim of the paper. The actual graph from the paper shows no "tipping point" but a gradual accele...
