evidence: NOAA’s US temperature record shows that US was warmest in the 1930’s and has generally cooled as CO2 has increased. This wrecks greenhouse gas theory, so they "adjust" the data to make it look like the US is warming. [...] The fabricated temperatures have warmed four degrees since 1970, relative to the adjusted temperatures which were based on actual station data. This shows that the warming trend in the US claimed by NOAA is based on computer models, not actual thermometer data or even adjusted thermometer data. [...] Science doesn’t get any worse than how NOAA handles US temperature data. NASA uses the NOAA data as the basis for their temperature graphs, which have also been massively altered to turn cooling into warming.
