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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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.
