from the spring-has-sprung dept.

The Washington Post reports that the "lower 48" states of the USA are enjoying spring-like weather. It quotes a meteorologist as saying 1495 record high temperatures have been reached during the month of February (as against 10 record lows); among them:

  • Magnum, Okla., hit 99 degrees [Fahrenheit, 37.2° Celsius] on Feb. 11 — tying the state record for hottest winter temperature ever recorded. Yet it occurred two weeks earlier than the record it matched from Feb. 24, 1918, set in the town of Arapaho.
  • Denver hit 80 degrees [Fahrenheit, 26.7° Celsius] Feb. 10 — its warmest February temperature on record dating back to 1872.
  • Norfolk hit 82 degrees [Fahrenheit, 27.8° Celsius] Feb. 12, tying its warmest February temperature on record dating back to 1874.

[Ed Note: it is actually Mangum, OK, not Magnum. The original WaPo article is incorrect.]

    I read TFS, and noted that with all this global warming, the US is now as warm as it was in the 1870's. Interesting. We have records showing that the temps were this high 140 or 150 years ago, yet we're concerned about global warming.

    I scanned the source article and I saw nothing like that. There was a mention of records going back that far but they didn't say when the matching temperatures occurred.

    Before someone goes all ape-shit-crazy on me - yeah, I do believe that climate change is for real. I've mentioned before that I learned in 1963, or thereabouts, that we were in an "interglacial period", and the earth was slowly warming up.

    We passed peak warm-up some 8,000 years ago. It was slowly cooling until we started overloading the atmosphere with CO2. Now it is warming much faster than it cooled, yet it still takes decades to be noticeable.

    Peak warmup, 8000 years ago? Slowly cooling since then? History in Europe demonstrates that the climate hasn't been steadily and slowly cooling for 8000 years. Remember that mini-ice age, that had people fearing that the earth was going to freeze over again? Are you sure you're not making stuff up now?

      So this is not history repeating itself, it is only Runaway repeating himself. Again. Oh dear.

      It's well known. There was even a comic about it: https://xkcd.com/1732/ [xkcd.com]

      I'm sure you've seen this before. Perhaps you dismissed it because it was a comic, but the science [wikipedia.org] was established long before.

      Of course, we may have passed that by now. CO2 will do that.

    The data being used to approximate the rate of warming is not the same as the proxy being used to measure the historical rate of cooling. You simply can't meaningfully compare such data sets that have completely different resolutions. The old data is *massively* averaged, and thus movement is damped, the new data is peaky, still full of noise, and were you to average it to the same extent as the old data, would simply not contain enough data to draw any accurate conclusions.

    > There was a mention of records going back that far but they didn't say when the matching temperatures occurred.

    In the summary I had put:

    Denver hit 80 degrees [Fahrenheit, 26.7° Celsius] Feb. 10 — its warmest February temperature on record dating back to 1872.

    I can see how it could be read differently, but that does seem to have been the intended meaning.

    Record temperatures for Denver, for each day of February, are shown at:

    http://www.weather.gov/bou/den_records_feb [weather.gov]

    Temperatures of 77 Fahrenheit were reached on 1890-02-04 and 2006-02-28.

    I went to
    http://w2.weather.gov/climate/getclimate_nonjs.php?wfo=bou [weather.gov]

    and after I selected Denver and February 10th, 2017 it told me that the previous record high temperature for that day of February was 71 Fahrenheit, set in 1951:

    THE DENVER CO CLIMATE NORMALS FOR TODAY
                                                      NORMAL RECORD YEAR
      MAXIMUM TEMPERATURE (F) 45 71 1951
      MINIMUM TEMPERATURE (F) 18 -14 1933

    Tthe 80-degree temperature may be seen by selecting February 11th and looking in the "YESTERDAY" section. Hence the highest temperature previously measured in February was 77 degrees Fahrenheit, in 1890 and 2006.
