In 1976, the New York Times reported that the Northern Hemisphere had cooled nearly as much since 1945 as it rose in the first part of the century.
The National Academy Of Sciences reported this cooling.
But it didn’t fit the global warming agenda, so NASA has since made almost all of that cooling disappear.
NASA temperature data is propaganda, not science. Skeptics who pretend that NASA temperature data is legitimate, are enabling this scam.
