Anthony Watts is foxed yet again by temperature anomalies
Sou | 3:42 AM

I read the latest article from Anthony Watts at WUWT. It reminded me that he really is dumb as an ox and blind as a bat.

Now you and I know that temperatures have been going only one way - up. And it's been getting really hot these past few years. Last year was the third year in a row that was the hottest on record. This year is shaping up as possibly the second hottest.

So what does Anthony Watts do? He plunges deep into idiocy with a most ridiculous article today (archived here).

What got him worked up was that El Nino temperatures are no longer having an effect, now that the Pacific is ENSO neutral. He falsely claimed this in his headline: "2017 Global temperatures are leveling off – near 1980 temperatures"

Near 1980? Really? No, not really. Temperatures today are nowhere near 1980 temperatures.

Despite lots of people trying to help him over the years, Anthony, who mistakenly fancies himself as a temperature expert and was once a weather announcer, still can't tell his anomalies from his baselines.

What caught his attention and sent him down the rabbit hole, was a tweet from Ryan Maue, where he said: "Global temperatures have generally settled to +0.26°C compared to 1981-2010 climatology continuing downward glide thru 2017 (black line)", and posted this NCEP global temperature chart. (Click the chart to enlarge it, as usual):

Anthony then trotted off to NASA GISTemp and wrote his headline, and put up this chart. Notice how he added a little box showing the 1980 temperature. Notice too what the temperature has been the last few years. Notice particularly with what temperatures the zero on the left axis lines up:

You all see what he did there, don't you. Okay, some of you might not be familiar with the different temperature datasets.

The one that Ryan used measured the differences in temperature from a very recent period, 1981 to 2010.

The one that Anthony jumped to, measures differences in temperatures (anomalies) from an period thirty years earlier, 1951 to 1980.

The average of 81-2010 temperature is 0.43 C higher than the average of the 51-80 temperatures.

Last year, the temperature was 0.78 C higher than it was in 1980, 0.55 C higher than the 1981-2010 average, 0.99 C higher than the 1951-1980 average, and 1.24 C higher than the 1881 to 1910 average.

Here's some information for Anthony Watts:
The difference between the average temperature over 1980, and the average temperature last year is 0.78 C.

2016 was the hot one.The difference between May this year and May in 1980 is still 0.63 C.

There hasn't been a year as cold as 1980 in 24 years - not since 1993! And barring a cataclysm like a supervolcanic eruption, there's not likely to be another for thousands of years.

Is Anthony Watts (and you) plain stupid, deceitful or going senile?
