IPCC science scandals aren't new

The UN's climate change panel is reeling from a series of scandals about unsupported claims in its 2007 report.

  • India has documented that the Intergovernmental Panel's claim of Himalayan glaciers disappearing by 2035 was mere speculation—and has now been proven false.
  • The 2007 IPCC report claimed global warming could cut rain fed African food yields in half by 2020. New lead author Chris Field says this is highly unlikely, and he can find nothing in the report's supporting chapters to document it.
  • The Dutch are complaining that the IPCC said half of its land area lies below sea level, when the figure is actually 20 percent.

All this criticism is valid and long overdue. But the biggest scandal in the IPCC's closet remains its 1995 claim to finding a "discernible human influence" on the earth's changing climate. Lead author Ben Santer of the Lawrence Livermore government laboratory inserted those words—after the IPCC's consulting scientists had signed off on a draft that specifically said no such "human fingerprint" had been found! 

Santer deliberately reversed the meaning of the whole IPCC 1995 report—and the trajectory of every IPCC document since. He claimed the rewrite was justified by two of his own studies. However, Santer's papers "cherry-picked" the earth's temperature record from 1963–1987, ignoring the earlier and later temperatures that didn't confirm the Greenhouse theory! Thus the IPCC's whole claim of a "discernible human influence" remains without scientific support to this day.

What will we learn next about the IPCC and its frolicking alarmists? Expect proof that the land-based thermometer records have been deliberately sabotaged to lower the temperature readings of yesteryear and raise recent thermometer readings—to make global warming seem scarier.

The most obvious case of this record manipulation to date is in New Zealand, where the "official" graph shows the country's temperatures rose 0.92 degrees C through the 20th century. However, NIWA's own raw data showed no 20th-century temperature uptrend in any of its stations. Is it an accident that most of the world's raw climate historical data has disappeared? 

Veteran meteorologist Joe D'Aleo appeared on John Coleman's TV special at KUSI-TV on January 14, charging that U.S. official temperatures have been rigged by quietly dropping "cold" weather stations: those at high altitude, high latitude, or in rural areas.

Clear back in 1992, James Goodridge, then California State Climatologist, published a peer-reviewed paper that sorted the state's weather trends by county population. The urban counties had a strong upward trend of plus 3.14 degrees F per century. Rural stations showed no upward trend at all.

Looking back, an "official" global warming of 0.6 degrees since 1900 may not seem all that dramatic. Especially after a dozen years of non-warming. But think how hard it would have been for the global warming alarmists to panic the people if they'd admitted the rural areas hadn't warmed at all!  That "global warming" was mostly cities ratcheting up their own heat!

The supposedly dedicated "climate researchers" have nearly cost the world trillions of dollars in higher energy costs, agonies of wintertime suffering for the elderly "energy poor," and needless deaths for lack of air conditioning in the summers. They and the Green campaigners came awfully close to destroying human society as most of us have known it. ESR
