The uncertainty of science: Climate models still fail to predict mid- and long-term trends in the climate.
To test the forecast quality of the 23 most important climate models, the AWI scientists investigated how well these models were able to reproduce atmospheric teleconnection patterns over the past 50 years. A total of 9 known circulation patterns were investigated retrospectively, four of which in special detail. The result was that the spatial distribution of atmospheric teleconnection patterns is already described very well by some models. However, none of the models were able to reliably reproduce how strong or weak the Icelandic Low, Azores High and other meteorological centers of action were at a particular time over the last 50 years, i.e. the temporal distribution patterns. [emphasis mine]
The “centers of action” are large global weather patterns like el Nino that can influence the global climate worldwide. Most climate scientists believe that global warming will manifest itself first in these centers of action. Yet, no climate model was able to predict what we know actually happened during the past fifty years with these large centers.
But we must ignore this fact and base all our climate law on what these models predict. What could go wrong?
In related news, the United Kingdom had its coldest autumn since 1993 this year. And if you look at the temperature graph at the link, covering autumn temperatures since 1910, you will notice hardly any change, up or down.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Does anyone else notice how the argument has turned from “man made global warming” to now
just “global warming”?
Mr Zimmerman?
JGL…. I don’t know what you mean. Most climate scientists are jumping up and down demanding to be heard: Climate change is real, it’s destructive, and it’s caused by humans burning fossil fuels. But too few are listening.
The argument use to always be underpinned with the “fact” that climate change was
happening and it was caused by human activity specifically.
Most interviews I hear now (I happen to be listening to an interview right now on the Brian Leher
show, the subject is climate change and no mention of it being human caused )
only identify climate change and not human caused climate change.
Is there climate change ?
Yes, the earth like the universe is not static, the climate is always in a state of change, we
are in the end of a cycle of ice right now. If you have read anything that Mr. Zimmerman has
posted on the subject, human cause is far from been established as the main driver in climate
change. I believe it has also been established that the main driver of “human caused” climate
change has been political. Do humans have an effect on the environment in which they live?
Of course, but what is that effect really?
I think the real discussion should be pollution, however the more powerful political tool is human
caused climate change.
