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.

All this tampering for a world carbon 666 tax.  It is fake science and they have created a carbon 666 religion out of it.
