Issues with weather stations

A little background reading is here and here.

An excerpt from that first link:
The preliminary results show Watts and his volunteers have surveyed about a quarter of the 1,221 stations making up the U.S. Historical Climatology Network. Of those, more than half appear to fall short of federal guidelines for optimum placement.

Some examples include weather stations placed near sewage treatment plants, parking lots, and near cars, buildings and air-conditioners — all artificial heat sources which could affect temperature records.
An excerpt from that second link:
Now I know there will be the usual critics who will jump in and say "This can be adjusted for!". Ok here is your chance, show me the equations to untangle Titusville's temperature record from microsite bias. Personally, it looks FUBAR to me.

Since you are doing selective quoting, how about this from the same Chico article:

"In addition to the USHCN, Lawrimore said the center uses numerous sources to monitor climate, including other surface temperature stations, satellites and ocean buoys.

"We don't rely on a single network or a single set of stations to understand how the climate is varying and changing," he said. "

Did anyone suggest that we rely on a single network or a single set of stations to understand how the climate is varying and changing?
