If people could look at the "Temperature History" of their local weather stations(not the Temperature vs time, but the change in temperature vs when it was published), they would come to this conclusion.
I started looking the local temperature stations in my area in the 90's. They did not show any temperature trend then, but the have now been "adjusted" to show the temperature increase reported by the current "scientists".
The problem is that it takes an official FOIA request to get access to the preadjusted data, because they don't want "non-scientists" to make their own conclusions.
The adjustments are clearly not based on equipment changes because they are continuous(not step changes). It is not possible to notice the adjustments until the data is side by side.
From the article:
“Nearly all of the warming they are now showing are in the adjustments,” Meteorologist Joe D’Aleo, a study co-author, told The Daily Caller News Foundation in an interview. “Each dataset pushed down the 1940s warming and pushed up the current warming.”
