Record cold in San Francisco

Record cold in San Francisco

And in Oakland. And in Salinas. And in Half Moon Bay. And in Gilroy. And in Livermore.
Must be a global warming hole in California today. ________________

20 Feb 2018 – The temperature in SFO fell to 36° this morning, breaking the record of 37° set back in 2011. OAK has tied its record of 34° last set in 2006. Both sites still have time to cool further before sunrise. Other records likely tied or broken across the region this morning.

  1. Delingpole: NOAA Caught Adjusting Big Freeze out of Existence
    The National Oceanic and Atmospheric Administration (NOAA) has yet again been caught exaggerating ‘global warming’ by fiddling with the raw temperature data.

    This time, that data concerns the recent record-breaking cold across the northeastern U.S. which NOAA is trying to erase from history.

    If you believe NOAA’s charts, there was nothing particularly unusual about this winter’s cold weather which caused sharks to freeze in the ocean and iguanas to drop out of trees.

    Here is NOAA’s January 2018 chart for Northeast U.S. – an area which includes New England along with NY, PA, NJ, DE and MD.
    You’d never guess from it that those regions had just experienced record-breaking cold, would you?

    That’s because, as Paul Homewood has discovered, NOAA has been cooking the books. Yet again – presumably for reasons more to do with ideology than meteorology – NOAA has adjusted past temperatures to look colder than they were and recent temperatures to look warmer than they were.

    We’re not talking fractions of a degree, here. The adjustments amount to a whopping 3.1 degrees F. This takes us well beyond the regions of error margins or innocent mistakes and deep into the realm of fiction and political propaganda.

    Homewood first smelt a rat when he examined the New York data sets.

    He was particularly puzzled at NOAA’s treatment of the especially cold winter that ravaged New York in 2013/14, which he describes here:

    The cold weather really began on Jan 2nd, when an Arctic front descended across much of the country, and extended well into March.

    The NWS wrote at the end of the winter:

    The winter of 2013-14 finished as one of the coldest winters in recent memory for New York State. Snowfall across Western and North Central New York was above normal for many areas, and in some locations well above normal. This winter comes on the heels of two previous mild winters, making the cold and snow this winter feel that much harsher.

    Temperatures this winter finished below normal every month, and the January through March timeframe finished at least 4 degrees below normal for the two primary climate stations of Western New York (Buffalo and Rochester)…..

    Relentless cold continued through the month of January across the region.

    So why, he wondered, did NOAA have this marked down as only the 30th coldest winter (since 1895) on its New York State charts, with a mean temperature of 16.9F?

    Homewood compared the local records for January 1943 and January 2014 – months which, according to NOAA’s charts, had very similar average temperatures.

    What he found was that NOAA’s charts were deeply inaccurate. The 2014 local temperatures had been adjusted upwards by NOAA and the 1943 local temperatures downwards.
    He concludes:

    On average the mean temperatures in Jan 2014 were 2.7F less than in 1943. Yet, according to NOAA, the difference was only 0.9F.

    Somehow, NOAA has adjusted past temperatures down, relatively, by 1.8F.

    Now, Homewood has given the same treatment to the most recent Big Freeze – the winter of 2017/2018.

    Yet again, he has found that NOAA’s arbitrary adjustments tell a lie. They claim that January 2018 was warmer in the New York region than January 1943, when the raw data from local stations tells us this just isn’t true.

    So at the three sites of Ithaca, Auburn and Geneva, we find that January 2018 was colder than January 1943 by 1.0, 1.7 and 1.3F respectively.

    Yet NOAA say that the division was 2.1F warmer last month. NOAA’s figure makes last month at least 3.1F warmer in comparison with 1943 than the actual station data warrants.

    He concludes:

    Clearly NOAA’s highly homogenised and adjusted version of the Central Lakes temperature record bears no resemblance at all the the actual station data.

    And if this one division is so badly in error, what confidence can there be that the rest of the US is any better?

    Well indeed. The key point here is that while NOAA frequently makes these adjustments to the raw data, it has never offered a convincing explanation as to why they are necessary. Nor yet, how exactly their adjusted data provides a more accurate version of the truth than the original data.
    He concludes:
    One excuse NOAA’s apologists make is that weather stations are subject to changing environmental conditions. For example, when the station sited at Syracuse in 1929 was located at what was originally just a sparse aerodrome. Since then, however, as Homewood notes, it has grown into a large international airport with two runways servicing two million passengers a year. Its weather station readings therefore will certainly have been corrupted by the Urban Heat Island effect: that is, its temperature readings will have been artificially elevated by the warmth from the surrounding development and aircraft engines.

    So you’d think, wouldn’t you, that to compensate for this NOAA would adjust the recent temperatures downwards. Instead, for no obvious reasons, it has adjusted them upwards.

    This is a scandal. NOAA’s climate gatekeepers are political activists not honest scientists and the U.S. taxpayer has no business funding their propaganda.

    Drain the swamp!

    • I bought a rain gauge before we had the record rainfall last year here in California (San Diego area) due to the pineapple express. I checked my analog data against NOAA and local homeowner weather stations (via weather underground), along with some of the local meteorologists’ data. All of the data were pretty consistent within a tenth or two except for NOAA’s, which was consistently 3/4″ to 1″ lower than my data and everyone else’s. Since then I don’t believe anything that NOAA says. I’m convinced they were fudging the numbers to make the drought look worse than it was so that the statewide water restrictions could legally remain in place. I’m very annoyed that my tax dollars are being used to push propaganda.

  2. I am currently at Oakland Airport about to fly back to UK. Yes it was cold last night and the night before. Big headlines locally – records broken etc. Was up at Lake Tahoe a few days back and that made San Fran look tropical !

  3. “The coldest winter I ever spent was spring in San Francisco” Mark Twain, or something like that, a humid cold I guess.

    • Well it’s also raw, windy and damp.
      I lived there from Feb 1969-April 1970. First thing I did when I hit town was throw out my winter coat and umbrella… thinking I was in “sunny” California… BIG mistake!

      I think we had nice mild and sunny weather maybe a week or two the entire time I was there. Rest of the time damp, cold winds, foggy, cloudy, etc. Part of why I prefer Southern CA!

  4. Yeah, It’s been cold here. All depends on which side of a meridianal loop you are on. Was very warm with too early bud bust. Now too cold. Various seasonal fruit trees will have issues and maybe even some crop loss.

    Unusual in the last 30 years, a lot like the ’70s.

    I hope the Arctic / Canadian air leaves and the Mexican Desert air returns… soon :-}

  5. and of course those are the people in those big cities out there that have been screaming that snow is a thing of the past long by now. California is the worst among those types!! Maybe the frost will teach them but I doubt it……..

  6. It wasn’t just San Francisco, the whole state was cold yesterday. In my town of Poway (San Diego county), it was 23/57F when normally it should be 38/65F. Can’t tell you for my town, but nearby Ramona, in San Diego County where the NOAA keeps records, Feb 20th had a record low of 23F and Feb 21st had a record low of 24, with recording starting in 1974.

    • yuke, not my idea of fun… Any idea what it was like in Alpine (where I used to live)? When I lived there… we often got cooler nights there, but more like in the 40s at a low. And there are places named things like “Frosty Acres” (fruit and nut place) in Alpine and something similar in Pine Valley… where it tends to get even colder in winter, sometimes snows up in Mt. Laguna.

      Where you there during the Cedar Fire? I was, left because of it… and aboth Ramona & Poway got hit real bad. But sometimes I really wish I hadn’t left. The weather there is still a lot better than here in southeastern VA .. where we get both snow some times, ice storms some times… and horribly humid hot summers.

  7. I had to let the car warm up to melt the ice off the windshield yesterday (San Mateo County)… it took 15 minutes before I could see to drive to work.

    D@mn you, GoreBull Warming!

  8. In addition to the ice on my windshield, apparently the cold killed my car battery… it wouldn’t start today after work. I got a jump and drove straight to Kragen, borrowed their tools and took the old battery out. The sides were swollen outward, so it apparently froze on the 20th… it’s 7 years old, so I expected it to go soon. The cold apparently hastened its demise.
