It is easy to blame Obama for the corruption of climate science, but the real credit goes to Al Gore in 1993.
As of 1990, NOAA had satellite sea ice data going back to 1973, which showed that sea ice extent was much lower in the early 1970s than in 1979.
But all of the NOAA pre-1979 sea ice data disappeared after Al Gore took office, because it wrecked his CO2 agenda.
As of 1990, the IPCC showed a much warmer Medieval Warm Period and much colder Little Ice Age.
But by the time Al Gore left office, the MWP and LIA had disappeared.
Similar story with sea level. As of 1990, sea level rise at the IPCC was less than five inches from 1880 to 1980.
Government agencies now claim almost twice that much sea level rise.
Under Al Gore, the criminal behavior of government agencies corrupting data, fraud and defunding skeptics began. Obama has simply extended and expanded Al Gore’s fraud.
