Buenos Aires and La Estanzuela are located 35 miles apart across the water. Buenos Aires is a massive heat island, and La Estanzuela is a small town of a few thousand people.
Buenos Aires warmed tremendously from 1931 to 1995, the period of record for the La Estanzuela station.
The two degree warming trend at Buenos Aires is bogus. The area is actually cooling. So how did NASA and NOAA deal with this? They reduced the two degree warming trend to 1.5 degrees warming.
The surface temperature record is a farce. These people make no attempt to be even remotely credible.
