I am aware that you have learnt to copy and paste Ajax. What I asked was, do you know how to measure atmospheric temperature with a satellite?

They use differing algorithms petal.

Of course those that don't do satellite data rely on use the Reynolds Reconstructed Sea Surface Temperature. And according to Phil Jones CRU the normals for the SST in the Southern hemisphere were mostly made up.

"Tom,
        The issue Ray alludes to is that in addition to the issue
      of many more drifters providing measurements over the last
      5-10 years, the measurements are coming in from places where
      we didn't have much ship data in the past. For much of the SH
      between 40 and 60S the normals are mostly made up as there is
      very little ship data there.
        Whatever causes the divergence in your plot it is down to
      the ocean.

You could try doing an additional plot. Download from
      the CRU web site the series for SH land. It doesn't matter if
      is from CRUTEM3 or CRUTEM3v (the former would be better). If that
      still has the divergence, then it is the oceans causing the
      problem. What you're seeing is too rapid to be real.
      Cheers
      Phil"

So no real data until about 2000. And yet you pin your faith to temperature reconstructions going back to 1880 or in some cases 1850. Of course there would be even less data from 40S to 85S. Bizarre.

yeah the same as NOAA, HadCruT and GIStemp and yet you have no trouble with them.

That's hilarious after your previous attempts to belittle them. Remember I showed that REMSS graph and how the climate models were getting further away from them.



Did you notice how the models were closer to the data earlier rather than later in the series?

What that the difference between the climate models and the satellite data is widening. 

Yes petal it is and it shows the models are warming too much. The clueless one is you.

You really should get a clue.

Edit: "Fig. 1.  Global (70S to 80N) Mean TLT Anomaly plotted as a function of time.  The black line is the time series for the  RSS V4.0 MSU/AMSU atmosperhic temperature dataset.  The yellow band is the 5% to 95% range of output from CMIP-5 climate simulations. The mean value of each time series average from 1979-1984 is set to zero so the changes over time can be more easily seen.  Note that after 1998, the observations are likely to be in the lower part of the model distribution, indicating that there is a small discrepancy between the model predictions and the satelllite observations.(All time series have been smoothed to remove variabilty on time scales shorter than 6 months.)"

It isn't arbitrary. The models are showing warming as compared to observations.

freediver wrote on Jul 17^th, 2021 at 8:40am:



No petal. Anomalies may go up and down but they should also go up and down in some sort of sync with the observations. They don't.

freediver wrote on Jul 17^th, 2021 at 8:40am:



Poor petal. Can you give any evidence of anyone, bar you of course, who disbelieves the satellite data.

Even SkepSci acknowledges the problem. Carl Mears of RSS (or REMSS if you prefer) is a climate alarmist.But even he admits the models are warming too fast.

freediver wrote on Jul 18^th, 2021 at 8:49am:


Offset against what exactly? The satellites have their anomaly data. The models have their anomaly data. So you tell us how it is done.

So who is claiming a cooling trend for "a long time"?

freediver wrote on Jul 18^th, 2021 at 8:49am:



Yes you have been told many times. You refuse to learn. You started out saying it was bunk. Then you went to maybe it is not bunk. And no where have you shown you know anything about it.

The plot is up to 2018.  Nowhere near a decade ago. So now we know you can't even read a graph.
