How dare scientists report what has happened!
This time he's up in arms about the fact that scientists have looked very closely at what has happened to global surface temperatures over the past few years, compared it with climate models and found that there is not a lot of difference in the end. The reason is that natural variability, mainly ENSO, has kept the heat in the oceans and hasn't released big chunks for a few years. Climate models aren't designed to mimic every little interannual variation in synch with the weather. Their projections are for longer term trends. As well as that the observations haven't been keeping up with the rapid warming in the Arctic. Add in aerosols and the slightly dimmer sun and what do you get? The models are pretty good.
Anthony is furious that scientists would report this sort of thing. What he's complaining about is a new letter in Nature Geoscience, by Markus Huber & Reto Knutti who did a review of recent work on global surface temperatures. They looked at some of the work done a little while back, where models outputs were reviewed to take account of actual observations (or estimates) of aerosols, volcanoes, solar radiation and ENSO. They also looked at the work of Kevin Cowtan and Robert Way in regard to Arctic temperature trends. They put it all together and came up with what many other scientists have figured - that the models aren't that different to observations once you take all these factors into account.
Well, that was all too much for Anthony's tiny brain to absorb. He can't cope with reality. He's dead against the idea of bringing what's actually happened into account. This is what he wrote (archived here):
This quote from ETH Zurich is actually from another just published post, but it is so grating, so anti-science, that it deserves its very own thread to highlight it.
Here it is:
If the model data is corrected downwards, as suggested by the ETH researchers, and the measurement data is corrected upwards, as suggested by the British and Canadian researchers, then the model and actual observations are very similar.
Gosh.
This is like saying:
If we take all our economic projections for performance as suggested by our financial models, and correct it downwards, and at the same time, if we take all of our revenues and expenditures that are in the red, and adjust them upwards, out company will be on track and our investors will be satisfied.
Except, people go to jail for that sort of thing.
Anthony Watts is no economist, finance expert or accountant
You can tell that Anthony's never looked at a balance sheet and that he hasn't a clue about any of economics, finance and accounting. What does he get wrong? First of all, he's got economics mixed up with finance mixed up with accounting. And you don't have "revenues and expenditures in the red". You're "in the red" if you're bank balance is negative (you've got an overdraft) or your current liabilities exceed your current assets. And one doesn't make economic projections from financial models. You can make financial projections from financial models.
But it's worse than that. Anthony's got it all back to front. If companies don't issue updates to the stock exchange when their circumstances change, well that's when directors can go to gaol. If they try to hide the fact that things went awry in their financial projections and they are suddenly blessed with a much bigger profit or have suffered a huge loss, then they will get into strife.
Thing is, anyone who is monitoring what is expected against what has happened is doing the responsible thing by reporting it. If a financial projection is based on an expectation of high sales because of a upturn in the economy, and then there's a financial crisis - then the projection needs to be revised.
About the paper
If you want to read about the paper that so muddled Anthony's already muddled brain, you can read it at Nature Geoscience if you've got a subs or otherwise have access. Or you can read the press release at Eidgenössische Technische Hochschule Zürich.
From the WUWT comments
As expected there are gasps and shrieks of indignation that anyone would examine what has actually happened in the world over the past few years. What cheek those scientists have. How dare they look at the data. That goes against everything that deniers hold sacred.
Frank K. is appalled that scientists would report their findings and says:

This is the most perverted use of the word “corrected” I have EVER seen. Just stunning…
David Johnson is speechless but not wordless and says:

I am speechless.
JohnB wonders what all the fuss is about and says:

A bit of context…
The “downward correction” is to account for the predominance of La Nina over recent years.
The “upward correction” is to account for bias due to lack of arctic temperature stations.
Unreasonable?
PeterB in Indianapolis doesn't understand that the science was based on what actually happened and says:

So basically, if we make sh*t up to match what we think is the “right answer”, then we can finally demonstrate that our answer is right!

“Except, people go to jail for that sort of thing.”
Not if they are Chairing a Central Bank they don’t.
Nor if they go by the name of Matt Ridley and chair a bank called Northern Rock.

John, John, John… We can’t adjust the models. They are based on sacrosanct laws of physics. To adjust them would be to “deny the science”. Surely you don’t want to be called a denier.
As for the temperature data, it has been adjusted enought already (way more than enough actually). So here’s what we do: Throw out the adjusted temperature data and use the satellite temperature data instead. Compare that to the unadjusted model outputs and see what you get.
Report back to us to let us know how that works out.
Louis, I'll go one better. Rather than throw away good data, let's compare four temperature data sets, including two satellite measures of the lower troposphere and two surface data. They are remarkable only for their similarity.

All the rest of the comments are much the same. Deniers don't want to see scientists reporting what has actually happened. They can't bear to lose one of their favourite faked memes that "all the models are wrong". They are all in a tizz because the models are most likely pretty right after all.
PS Maybe Anthony's mind hasn't been on his blog because he's putting the final, final, final finishing touches on his brand new "getting older every day" paper that has yet to see the light of day. Go comment about that at Stoat :)
