New NASA Data Casts Doubt On Global Warming Models
bonch writes "Satellite data from NASA covering 2000 through 2011 cast doubt on current computer models predicting global warming, according to a new study. The data shows that much less heat is retained by carbon dioxide in the earth's atmosphere than is assumed in current models. 'There is a huge discrepancy between the data and the forecasts that is especially big over the oceans,' said Dr. Roy Spencer, a co-author of the study and research scientist at the University of Alabama." Note: the press release about the study is somewhat less over the top.
A few notes about TFA:
1) The data comes from satellites put into space by NASA, but NASA is in no way involved in this study.
2) If this study actually significantly contradicts our knowledge of global heating, why has it been published in Remote Sensing, and not a more reputable journal?
3) They only interviewed the guy from the University of Alabama who lead the study
4) The author works for The Heartland Institute
5) They seem to have replaced the words "accurate" and "accepted by the scientific community" with "alarmist"
6) Source on UN's involvement? Seems like they threw that one in just to go for the "UN = bad" reaction that a lot of people have
Dr Roy Spencer is a creationist. A proponent of intelligent design.
His work has been largely criticized in the peer review literature.
The guy who wrote this article is a little biased. The original paper is available online for those who want to see what it really has to say.

Anyone who is inclined to give a lot of weight to this "alarmist" press release should first read this, on a previous paper from Roy Spencer. Note this
what he gets through peer-review is far less threatening to the mainstream picture of anthropogenic global warming than you’d think from the spin he puts on it in press releases, presentations and the blogosphere.
Now, also read the paper, and note this
It is concluded that atmospheric feedback diagnosis of the climate system remains an unsolved problem, due primarily to the inability to distinguish between radiative forcing and radiative feedback in satellite radiative budget observations.
Hmm, doesn't sound like the press release or the Forbes article much, does it ?
Use the above and your judgement to figure out just how much weight to give the above.
The author of this fine piece is a senior fellow at the Heartland Institute, a libertarian think tank that seems to think global warming is some sort of fairy tale. This is the same group that worked with Phillip Morris to deny the link between second hand smoke and lung cancer. It would be fantastic for Forbes, Yahoo!, or maybe even Timothy make some effort to mention that this is essentially an OpEd posing as a news report. Instead we get this bullshit that's going to pull in the teenage libertarian "See global warming is made up!" short bus riders.

The paper doesn't do anything close to what the summary suggests, nor what either story suggests. The submitter is basically trolling it up.
The paper is available for all to read here: http://www.mdpi.com/2072-4292/3/8/1603/pdf
Basically, they are talking about lack of model sensitivity for non-radiative feedback, which is something that was already known. The models on a MONTHLY basis don't go high enough on the maximums and don't go low enough on the minimums (and there is a lag). Or in other words, the models get the general predictions right (warmer temperatures) but don't capture shorter term variability as well (heat waves, cold snaps).
Of course, it's already well known that climate models don't capture short term variability very well. However, this paper helps quantify that and provides some insights on how to better improve that aspect of modeling.
Or if you don't want to read the whole paper just skip to the conclusions sections, which mention nothing about invalidating global warming or the science thereof.
How that gets translated into "New Study Trashes Global Warming" is beyond me.

Slashdot editors, please try to remember that a single paper normally doesn't overturn scientific understanding, and try to avoid habitual hype sources. Thanks.

Input, in this case was the collected data from weather stations, satellites, ice cores, tree rings, etc.
The historical weather record is not used as input it is used to test the model via hind-casting. The inputs to the models are things such as the strength of gravity, the composition of the atmosphere, the absorption spectra of GHG's, the shape of the Earth's geode, etc. The 'logic" is the laws of physics and chemistry. The algothim that brings them together is called finite element analysis and is used on everything from designing casts for engine blocks to building bridges for them to drive across.
As for TFA, the author of the paper, Roy Spencer, is a creationist quack who has expanded his quackery into AGW, his claims on anything scientific should be taken with a truckload of salt.
