Climate alarmists foiled: No U.S. warming since 2005

Somehow this apparently innocuous non-problem has to be hyped up into a crisis of epic proportions. To help achieve this, an army of climate spin doctors is always on hand to attempt the never-ending task of blaming humans for any kind of unpleasant weather.

When American climate alarmists claim to have witnessed the effects of global warming, they must be referring to a time beyond 14 years ago, says James Taylor @ RealClear Energy.

That is because there has been no warming in the United States since at least 2005, according to updated data from the National Oceanic and Atmospheric Administration (NOAA).

In January 2005, NOAA began recording temperatures at its newly built U.S. Climate Reference Network (USCRN). USCRN 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 pre-existing 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The USCRN has eliminated the need to rely on, and adjust the data from, outdated temperature stations. Strikingly, as shown in the graph below (here), USCRN temperature stations show no warming since 2005 when the network went online. If anything, U.S. temperatures are now slightly cooler than they were 14 years ago.

Climate activists frequently visit or mention particular regions, states, or places in the United States and claim warming impacts are evident, accelerating, and unmistakable. Yet how can that be when there has been no warming in the United States since at least 2005?

Unfortunately, when politicians and climate activists claim they can see the impacts of climate change in a particular place, the media rarely question them on it and tend to accept the claims at face value. But the objective temperature data show no recent warming has occurred.

There is also good reason to believe U.S. temperatures have not warmed at all since the 1930s. Raw temperature readings at the pre-existing stations indicate temperatures are the same now as 80 years ago. All of the asserted U.S. warming since 1930 is the product of the controversial adjustments made to the raw data.

Skeptics point out that as the American population has grown, so has the artificial warming signal generated by growing cities, more asphalt, more automobiles, and more machinery.

    The propaganda has worked so well the Club of Rome has not really needed to publish anything new since 1973.

    Oh Dear! We can’t have this. The grant structure for USCRN must be re-arranged so that this data is paywalled and homogenised into step with the other data bases. (sarc.

    It’s very simple. Just subtract the raw temperature from the “adjusted” final temperature and plot that on a graph with the level of CO2 plotted on it. Oh shock and surprise, the “adjustments” follow the CO2 levels (upwards) while the raw data median value pretty much stays level.

    No U.S. warming since 2005

    And since 2005 we’ve had two extra-low solar cycle minima, one of which is still in progress. What effect have reduced solar magnetism and lower solar wind strength had on the jet stream?

  5. Kelvin Vaughan says:

    The energy of an electromagnetic wave is proportional to its frequency.
    A temperature is made up of a range of frequencies as shown in a black body curve.
    Taking each individual frequency of the band a hot object will have all the frequencies of the cold object but a colder object will not have all the frequencies of the hotter object.
    Adding two lots of the same frequency results in the same frequency i.e. the same energy. It will not increase the frequency. You have to increase the frequency to increase the energy.
    Here is a sine wave adder.
    The frequencies can be set with w1 and w2.
    You will notice the result of adding sine waves of different frequencies always results in a wave with the frequency the same as the highest frequency.
    Therefore a cold object cannot increase the temperature of a hot object.

    Kelvin’s electrical? analysis is correct. Energy in a wave hµ (nu not micro) Boltzman constant times wavelength. If my memory serves me well. Which it doesn’t these days.

    taking each individual frequency of the band a hot object will have all the frequencies of the cold object but a colder object will not have all the frequencies of the hotter object.
