MEDIA ADVISORY: 96% OF U.S. CLIMATE DATA IS CORRUPTED
Official NOAA temperature stations produce corrupted knowledge as a consequence of purposeful placement in man-made scorching spots
Nationwide research follows up widespread corruption and warmth biases discovered at NOAA stations in 2009, and the heat-bias distortion drawback is even worse now
ARLINGTON HEIGHTS, IL (July 27, 2022) – A brand new research, Corrupted Local weather Stations: The Official U.S. Floor Temperature File Stays Fatally Flawed, finds roughly 96 % of U.S. temperature stations used to measure local weather change fail to fulfill what the Nationwide Oceanic and Atmospheric Administration (NOAA) considers to be “acceptable” and uncorrupted placement by its personal printed requirements.
The report, printed by The Heartland Institute, was compiled by way of satellite tv for pc and in-person survey visits to NOAA climate stations that contribute to the “official” land temperature knowledge in america. The analysis reveals that 96% of those stations are corrupted by localized results of urbanization – producing heat-bias due to their shut proximity to asphalt, equipment, and different heat-producing, heat-trapping, or heat-accentuating objects. Putting temperature stations in such places violates NOAA’s personal printed requirements (see part 3.1 at this hyperlink), and strongly undermines the legitimacy and the magnitude of the official consensus on long-term local weather warming developments in america.
“With a 96 % warm-bias in U.S. temperature measurements, it’s unattainable to make use of any statistical strategies to derive an correct local weather pattern for the U.S.” stated Heartland Institute Senior Fellow Anthony Watts, the director of the research. “Information from the stations that haven’t been corrupted by defective placement present a price of warming in america lowered by virtually half in comparison with all stations.”
NOAA’s “Necessities and Requirements for [National Weather Service] Local weather Observations” instructs that temperature knowledge devices have to be “over stage terrain (earth or sod) typical of the realm across the station and not less than 100 toes from any intensive concrete or paved floor.” And that “all makes an attempt will probably be made to keep away from areas the place tough terrain or air drainage are confirmed to end in non-representative temperature knowledge.” This new report reveals that instruction is often violated.

This new report is a observe as much as a March 2009 research, titled “Is the U.S. Floor Temperature File Dependable?” which highlighted a subset of over 1,000 surveyed stations and located 89 % of stations had heat-bias points. In April and Might 2022, The Heartland Institute’s staff of researchers visited most of the identical temperature stations as in 2009, plus many not visited earlier than. The brand new survey sampled 128 NOAA stations, and located the issue of heat-bias has solely gotten worse.
“The unique 2009 floor stations challenge demonstrated conclusively that the federal authorities’s floor temperature monitoring system was damaged, with the overwhelming majority of stations not assembly NOAA’s personal requirements for trustworthiness and high quality. Investigations by authorities watchdogs OIG and GAO confirmed the 2009 report findings,” stated H. Sterling Burnett, director of the Arthur B. Robinson Middle on Local weather and Surroundings Coverage at The Heartland Institute who surveyed NOAA floor stations himself this spring. “This new research is proof of two issues. First, the federal government is both inept or stubbornly refuses to be taught from its errors for political causes. Second, the federal government’s official temperature document can’t be trusted. It displays a transparent city warmth bias impact, not nationwide temperature developments.”
An instance of the bias drawback
The chart beneath, discovered on web page 17 of the report, reveals 30 years of information from NOAA temperature stations within the Continental United States (CONUS). The blue traces present recorded temperatures and the pattern from stations that adjust to NOAA’s printed requirements. The yellow traces are temperatures taken from stations that aren’t compliant with these requirements (i.e. close to synthetic scorching spots). The crimson traces are the “official” adjusted temperature launched by NOAA.
“For those who take a look at the unperturbed stations that adhere to NOAA’s printed commonplace – ones which might be accurately situated and freed from localized city warmth biases – they show about half the speed of warming in comparison with perturbed stations which have such biases,” Watts stated. “But, NOAA continues to make use of the info from their warm-biased century-old floor temperature networks to provide month-to-month and yearly experiences to the U.S. public on the state of the local weather.”
“The difficulty of localized heat-bias with these stations has been confirmed in a real-world experiment performed by Oak Ridge Nationwide Laboratory and printed in a peer reviewed science journal.” Watts added.
“In contrast, NOAA operates a state-of-the-art floor temperature community referred to as the U.S. Local weather Reference Community,” Watts stated. “It is freed from localized warmth biases by design, however the knowledge it produces isn’t talked about in month-to-month or yearly local weather experiences printed by NOAA for public consumption.
The Heartland Institute, a free-market assume tank based in 1984, is likely one of the world’s main organizations selling the work of scientists who’re skeptical that human exercise is inflicting a local weather disaster.
Heartland has hosted 14 Worldwide Conferences on Local weather Change attended by 1000’s since 2008, printed the six-volume Local weather Change Reconsidered sequence by the Nongovernmental Worldwide Panel on Local weather Change, and for 21 years has printed Surroundings and Local weather Information. The Heartland Institute has additionally printed a number of fashionable books on the local weather, together with Why Scientists Disagree About World Warming (2015), Seven Theories of Local weather Change (2010), and Is the U.S. Floor Temperature File Dependable? (2009).
