NOAA Relies On ‘Compromised’ Thermometers That Inflate US Warming Trend
The National Oceanic and Atmospheric Administration’s reliance on poorly-sited weather stations to calculate surface temperatures is inflating the warming trend of the U.S. and maybe even the rest of the world, according to a landmark study looking at three decades of data.
“The majority of weather stations used by NOAA to detect climate change temperature signal have been compromised by encroachment of artificial surfaces like concrete, asphalt, and heat sources like air conditioner exhausts,” Anthony Watts, a seasoned meteorologist and lead author of the study, said in a statement Thursday.
These “compromised” weather stations run hotter than stations that are well-sited, and are used by NOAA as a benchmark to make upward adjustments for other weather stations that are part of the agency’s official temperature record.
Watts and his fellow researchers found only 410 “unperturbed” weather stations out of the 1,218 stations used by NOAA to determine U.S. climate trends. These “unperturbed” stations don’t need to be adjusted by NOAA because they had not been moved, had any equipment changes, or change in the time temperatures were observed.

I've known about this from other reports, including from NOAA itself for nearly 20 years.
Yes, the climate is changing and has shown a global trend warmer since the end of the "mini ice-age" in the early part of the 1800s. However, since formal tracking began in the late 1800s well after the beginning of the industrial age, the various governmental agencies have relied on not only poorly sited measuring equipment but often 2nd and 3rd hand reports or anecdotal evidence and estimates or interpretations of ice core samples where "precise timing" is often measured with built in errors of several centuries in samples millenia old.
The computer models used to predict climate change to come is built on data that is often wrong, skewed or "estimated" (guessed at.) "Garbage in - garbage out."
Yes, the climate is changing. Ours is a dynamic world and not a dead one, subject to any number of influences besides human.
