A peer-reviewed paper entitled “On the Validity of NOAA, NASA and Hadley CRU Global Average Surface Temperature Data & The Validity of EPA’s CO2 Endangerment Finding” claims to show that temperature datasets from NASA, the National Oceanic and Atmospheric Administration and the Met Office in the United Kingdom are the result of adjustments made to the datasets after temperatures were recorded, calling into question just how much warming is real and how much is pure fantasy.
The implications are huge. Most people think that the data is simply raw temperatures that have been recorded but that is not the case. The study states that “GAST data is not simply the raw temperature recordings. Rather, the data is adjusted after it is recorded to account for various problems, such as “contamination by urbanization.” Because temperatures are recorded in Urban areas there are a number of factors that have to be adjusted in order to accurately reflect the true temperature.
