There are a wide variety of views on climate change science, and everyone
who follows the scientific method with integrity is a skeptic. The grouping
of views into two opposing camps on anthopogenic climate warming, "skeptic"
and "non-skeptic," is a false and misleading dichotomy.
Some explicitly state the climate models "ignore real data," *(read here: *
http://icecap.us/index.php/go/about-us "...unwise reliance on imperfect
climate models while ignoring real data...), which implies not just a faulty
model, but deliberately using a model to replace "real data," as though
there is data without a model. This is a central issue in "A Vast
Machine." As author Edwards wrote in "A Vast Machine," as quoted in a
review of this book from American Scientist website:
http://www.americanscientist.org/bookshelf/pub/how-we-make-knowledge-about-climate-change
In the countless political controversies over climate change, the debate
often shakes out into a contest: models versus data.
This supposed contest is at best an illusion, at worst a deliberate
deception—because *without models, there are no data*. I’m not talking about
the difference between “raw” and “cooked” data. I mean this literally.
------------------ The following essay by Edwards in "Science" journal
might more fully explain this point of view. Note the essay is from 2004,
revealing Edwards has been working on his book, "A Vast Machine," published
in 2010, for many years

Regarding the DiPuccio "weblog" on ocean heat, for a self described
"skeptic," you are remarkably unskeptical when it comes to presenting
"scientific" statements as reliable, from sources that do not represent a
comprehensive and balanced view of all the published peer reviewed science
on a given issue.
You state unequivically that this "weblog," which is not published in a
credible peer reviewed science journal, demonstrates that "the climate
models" (all existing climate models regarding ocean heat, or only some?))
"have gotten the heat content of oceans wrong." You also write that the
models all use the "same type of assumptions" which does not say anything
without specifics. Of course all the climate models of integrity will
follow the law of conservation of energy (
http://www.grc.nasa.gov/WWW/K-12/airplane/thermo1f.html ) , for example.
This is not an error in the models.
At least Pielke's website warns the reader that DiPuccio is "not a published
climate scientist."
Without extensively researching this question, I would not assume this
DiPuccio "weblog" is an expression of a comprehensive and balanced analysis
of all the published science on this issue.
There are many theories and arguments presented in the world of science,
many of which are shown via peer review to be highly questionable. Other
theories and arguments hold up to rigorous skeptical peer review. Without
surveying all or most of the scientific peer review literature on a given
question, the question remains insufficiently examined.
I doubt you have done this research... If so, please correct my statement,
and present the comprehensive research. If not, why jump to the conclusion
this DiPuccio "weblog" is authoritative science?
At website below read a paper published in the Proceedings of the National
Academy of Sciences in Dec. 2009, by Vermeer and Rahmstorf, where they state
that "ocean heat uptake is not sufficiently understood" revealed by the fact
that "observed sea level rise exceeded that predicted by models" for the
examples they list. They explore errors in climate models in this paper.
The climate model Rahmstorf uses for the physics of the oceans accounts for
this uncertainty, if I understand correctly.
However, this uncertainty does not lead the authors to conclude that the
predictions of significant sea level rise by 2100 due to climate warming
from human impacts, are largely unreliable, given a range of predictions for
sea level rise, 75 to 190 cm (.75 to 1.9 meter), from 1990 to 2100. Note
this prediction states that IPCC AR 4 (2) predictions of sea level rise are
lower than their findings, if I read correctly:
