The scam never ends because the world is filled with ignorant people.
As for uncharted territory, true. But then we always were.
The modern thermometer was invented inn 1719. The first study of ocean temperature was done in the late 1770s by Benjamin Franklin on a trip he made to France to ask the French king for funding for the war of independence.
So, fortunately for the Warmist we have little real data to refute their alarmist claims.
The alarmist use to their advantage that the tracking of temperatures begins during the Little Ice Age and just before the Industrial Revolution.
But real global temperatures tracking does not really begin until the advent of weather Satellites in the 1980’s
So, the idiot author is correct we are in uncharted territory and always have been.
