SR continues his efforts to hide previous small errors behind current big errors.

NOAA - I've already shown data that they use the 1990-2020 where appropriate.

WMO - I've already shown data that they use the 1990-2020 where appropriate.

Climate.gov - "Earlier this spring, NOAA released the 1991-2020 U.S. Climate Normals—the new official baseline for describing average U.S. climate. "

RSS - the article you linked was written in 2018. I'll leave you to ponder why they weren't using 2020 data in 2018. Words fail me!!

I know this is difficult for you to follow but this isn't a black and white thing. Sometimes using 1990-2020 averages is right, sometimes other averages are more appropriate. So most of these climate organisations will use both depending on the circumstances.

But, although you clearly can't follow the logic, making these changes isn't a vast conspiracy to confuse the clueless, even though you are clearly confused. But then numbers always confuse you.

First Atlantic Warm Period about 7750 BC
Second Atlantic Warm Period about 7000 BC
First Saharan Warm period about 5800 BC
Second Saharan Warm Period about 5000 BC
Egyptian Warm period about 3200 BC
Sumerian Warm Period about 2200 BC
Minoan Warm Period about 1200 BC
Roman Warm Period about 400 BC to 300 AD
Medieval Warm Period about 1000 AD
Modern Warm Period about 2000 AD

Can ya see a pattern in there, Steelredux?

Question. How do you explain the previous, regularly occurring warming periods if you can't blame them on human industrial activity?

C'mon mate. Answer the question.

Dear mhaze,

You really are like a mangy cat on a hot tinn roof, desperate to deny the bleeding obvious, that you once again got caught out not reading the material you posted.

NOAA and WHO use changing normal in your own words "where appropriate".

It is not appropriate for global climate change monitoring.

Yet again:

“for the purposes of historical comparison and climate change monitoring, WMO still recommends the continuation of the 1961-1990 period for the computation and tracking global climate anomalies relative to a fixed and common reference period.”

Spencer's graphs are clearly marked as "global average lower tropospheric temperature (LT) anomaly". As a global representation designed to represent "the computation and tracking" a global climate anomaly this lies squarely under the WHO recommendation.

That Spencer chooses to ignore this recommendation to suit his agenda is recognisable to everyone with half a brain. Both he and you are engaging in deliberate obfuscation and I have rightly called you both out.

SR

Yes Yes we all understand.
You made an error, and as in all other occasions when you make an error you use increasingly inane assertions to try to hide the error and are flabbergasted that others don't buy those inane assertions.

Climate.org called the 1990-2020 numbers "the new official baseline" and UAH are using that "new official baseline". That this confuses you is neither here nor there and certainly not surprising.

But here's the only take from this that need concern your half-a-brain...the new baseline doesn't alter the trend lines and the UAH data shows the trendline for global temperature is no warming in the past decade.

BTW the WHO have nothing to do with this. I think you meant the WMO. Good to see how conversant you are with all the facts.

Dear mhaze,

Lol.

I do enjoy it when you squirm away like this. Your smoking gun that you produced with such fanfare at the start ended up being pointed backward didn't it. You really are a cartoon coyote aren't you. Good stuff.

So according to you: “UAH are using that "new official baseline"”.

For God's sake, did you really just go there? The main players in the University of Alabama in Huntsville team responsible for the record are two climate sceptics one of whom is Spencer himself.

So your evidence that this is widespread is to use the very same people who are being called out?

That is lame even in your book.

As to climate.gov they categorically state:

“The 1991-2020 Normals tell us what is normal in today’s climate. NOAA does other analyses that tell us about what used to be normal.

For its monthly and annual climate monitoring, temperature averages and precipitation totals are ranked since 1895, with many states ranking towards warm extremes recently. Also, U.S. and global climate conditions are compared to the 20th-century average.”

End of story old boy but do keep going, this is fun.

SR,

This is now beyond funny. You are amazed to find that Spencer and UAH are one and the same. Even though your original link was about UAH.

I keep making the mistake of assuming you have a modicum of requisite knowledge only to find that your level of understanding is lower than I thought possible. All of this and you didn't even know where your original link came from. Words fail me!!

Nowhere have I said the use of the new normal baseline was widespread. Indeed you'll note (well not you but someone with a modicum of understanding) that I've only mentioned US organisations. Being widespread was never the point although as usual your missed that. The point was that the new baseline was becoming acceptable and its use by UAH is just about keeping up to date. That it confused you is hardly surprising but that doesn't make it wrong.

After all, if the standard was to not confuse the likes of SR, then they'd never mention trendlines, since, as we've previously seen, that utterly confuses you.

Oh, did I mention that the trend for the last decade is no warming?

So enough. I can't go on trying to educate the ineducable.
