As the climate change hysterics from the Democrat presidential candidates continue, some of the actual facts seem to have gotten lost in the discussion.
John Hinderaker posted an article at Power Line Blog yesterday with the following headline, “No U.S. Warming Since 2005.”
The article reports:
Even when measured, temperature records are not very reliable. The U.S. is generally considered to have the best records, but surveys show that over half of our weather stations do not comply with written standards. Some are located in places that obviously will be warmer than surrounding air, e.g., next to airport runways. Many are in cities, where temperatures are artificially inflated by concentrations of people, motor vehicles, buildings, etc. And on top of all of that, the alarmists who curate weather records have systematically fiddled with them, lowering temperatures that were recorded decades ago and raising recent ones, to exaggerate the supposed phenomenon of global warming.
The article continues:
In order to address some of these problems, the National Oceanic and Atmospheric Administration (NOAA) implemented, beginning in 2005, a new surface temperature measurement system in the U.S.
[The U.S. Climate Reference Network] includes 114 pristinely maintained temperature stations spaced relatively uniformly across the lower 48 states. NOAA selected locations that were far away from urban and land-development impacts that might artificially taint temperature readings.
Prior to the USCRN going online, alarmists and skeptics sparred over the accuracy of reported temperature data. With most preexisting temperature stations located in or near urban settings that are subject to false temperature signals and create their own microclimates that change over time, government officials performed many often-controversial adjustments to the raw temperature data. Skeptics of an asserted climate crisis pointed out that most of the reported warming in the United States was non-existent in the raw temperature data, but was added to the record by government officials.
The USCRN has eliminated the need to rely on, and adjust the data from, outdated temperature stations.
So–not to keep you in suspense–what does the USCRN show so far? No warming:
