On January 21, Senator James Inhofe (R-OK) again displayed the same deception/incompetence that pervaded his book, The Greatest Hoax (2012).
In this video segment (3:00-5:20), he presented a poster on the Senate floor that matches the image below from “Kyoto by Degrees,” an anonymous Wall Street Journal (WSJ) Opinion piece, June 21, 2005. Both contained claims plausibly called academic or journalistic deception, created for public confusion.
Regardless of ancient tempreatures, modern temperature rise is human-caused, not just natural variation: you damaged your furnace so it now ignores the thermostat. Heat varies erratically, room by room, and day by day, but each week the house is overall wamer than the last. Your attic Arctic fridge's ice cubes are melting and even the basement freezer is starting to struggle. The furnace will take months to fix, and you need to start, whether or not you believe rumors that some previous owner experienced warmer weather.
Following is the WSJ image Inhofe used without mentioning that source:
“Trend in average” : Deception.
The original curve was sketched in 1965 by Hubert Lamb, who grafted estimates of 900-1680AD with 1680-1961AD measurements compiled by Gordon Manley. It covered a 21x34-mile patch of England.
“exactly as shown”: Falsification. false citation. Real science uses captions and caveats, ignored here by cherry-pickers who plucked the graph out of context and even altered the image.
“mean”: Fabrication to explain an unprovenanced image.
Someone just made it up. The IPCC wrote: ”The dotted line “nominally represents” the start of the 20th century.”
Lamb MWP curve never global, real science improves
The attached 4-page excerpt from IPCC(1990) includes the real p.202 image in context, shown below for easy comparison with this altered version. Someone changed “Years before present” (sic) to “Year,” deleted (c), capitalized all words and converted sans-serif to serif font.
The resulting image was copied along murky paths, including onto p.33 of Inhofe's Greatest Hoax book, which cited it as “Intergovernmental Panel on Climate Change, Climate Change, the IPCC Scientific Assessment 202 (1990). His story is clearly refuted by IPCC's surrounding text pp.199-203.
The real image was clearly captioned a schematic, i.e., a sketch. The 1990 scientists said the LIA was global, but they stated clear reservations about MWP as global and synchronous. IPCC(1992) had other curves, not this.
