If you don't mind, I'll repeat something from a few posts back because as far as i can tell, I've already answered your question. There is a problem with model predictions in the middle troposphere. But the middle troposphere is not key to proving or disproving AGW or estimates for global warming.
What I said before:
"As the narrator, Mark Richardson from NASA/JPL-Cal Tech says: "
Using the (absence of a predicted)
hot spot to cast doubt on greenhouse warming is a red herring. Its a sign of changing moisture in the tropics, not of greenhouse gas warming. A real fingerprint of greenhouse warming is warming near the surface while the atmosphere above 20 km cools this has already had a spectacular effect" as shown in satellite readings. (his words from the video are shown in italics.
The key point is, while it is true that the state of the science of global climate modelling and the science of measuring atmospheric temperatures at all elevations are not completely in synch.
What is also true is the fingerprint showing greenhouse global warming are exactly in sync. Predicted and measured rising surface temperature and upper troposphere cooling are confirmed."
This video answers your question better than I can.
That region is a really tricky for weather scientists to study global warming. First off, its very cold and a small region of atmosphere in between two really big regions -- the universe and the earth. Second, this region is dynamic, with a lot of variables in play. Third, satellite and weather balloons are a work in progress as far as the ability to accurately measure temperature with error much less than 0.1 C. This is why the middle troposphere is not a very good place upon which to base decisions regarding climate change. Also, for these reason it is a great place of science deniers to use to sow doubt.
Basically, it doesn't make sense for me to pick another data set from measurement 11 miles up. Its best to look at more data than that, such as the data summarized below:
This graph also shows Global Mean Surface Temperature is not increasing as predicted. That said, the error is not nearly as large as 50% per decade, as Curry said. From the graph above, the error more like 20% over 80 years. I'd be willing to bet that every scientist working on this problem, if asked about accuracy, would be pleased if they found their model was only off by 20% over a period of 80 years.
So, I'm not sure what we are arguing about any more, bugeye. We both agree that the Global weather model is overpredicting temperature rise. Is it that you would delay doing anything?
