Abe- I understand why you have great faith in CAGW....you simply accept climate science papers that agree with your views as the unvarnished truth. To you, there is no need for any skeptical examination of the accuracy of the data, no need to question the legitimacy of the conclusions. it's peer reviewed, right?
I joined this MB before climategate but I only came to this forum afterwards. I was predisposed to disagreeing with CAGW for several reasons. I have lived through enough concensus paradigms to know that they often are mistaken, especially when they create a financial windfall to a bureaucratic cohort. I am also smart, with enough math and science training to notice logical deficits in many of climate science claims.
take your sea ice example....what does it have to do with CO2? are you using sea ice as a proxy for temperature? are you testing your climate model predictions? if so, then they fail miserably at both poles with one having too much and the other too little. sea ice is obviously driven by many natural factors besides just temperature and we have only weak understanding of many of them.
a few years ago I read an article from the early 1920's that described spectacular ice loss and warmed sea surface temperatures for the european arctic region. I then looked up the official history for that area. the warming wasn't there! why would fishermen make up a story about their stock disappearing because of warmer temps? how were coal deposits found unless the ice really did disappear?
I wondered why the large retreat of glaciers before 1900 was simply ignored! what about the supposed 'history' of sea ice in the 20th century? was it consistent or 'homogenized' like the temperature record? I bet most of you know the answer to that!
the Icelandic temp records have been so mangled that periods of ice retreat and advancement dont match up with the temperature! perhaps CO2 affects the freezing point of water, eh?

Wrong on all counts. I do not have "faith" in the theory of AGW. My
opinion, based on the overwhelming consensus of the experts, is that it
is
extremely likely to be correct. I generally reserve the word
"truth" for mathematical axioms or other universally recognized, a
priori statements of principle or rule. I do not use the term for
theories of natural science.

Why do
you waste time trying to tell
me what I think? I
am a steadfast believer in the scientific method. That does NOT mean
that I think conclusions resulting from its exercise are infalliable
truths NOR that they should consistently be treated as suspect,
unsupported conjecture. The degree to which I hold any scientific
conclusion likely to be correct is based on the responses and
observations I read, see and hear from the scientific community on the
specific topic. And while I understand that scientists who feel they
have better explanations for given observations or that find
falsifications of accepted theory, should certainly bring them forward
(and do, as one of the best ways to enhance a career in science) -
I am not a scientist. I have neither the knowledge set
nor the time to do any more research than click a few links and read a
few articles. I have taken the time to note that a
very strong
consensus exists among the world's climate experts regarding AGW and the
threat it presents to us and more so to our descendants. Based on that
consensus, I accept AGW as, by far, the likeliest description of what
this planet's climate is actually doing. Based on the threat it levels
against my children and theirs and the rest of humanity for many
generations, I choose to work to ameliorate the threat as I can. One of
the tasks with which those choices present me is to debate those who
reject AGW in public forums. Why are you here? What are you
protecting? What evil do you seek to stop? Excessive sensitivity to
environmental degradation?

Consensus paradigms are often mistaken? I disagree. An examination of
consensus positions on matters of natural science since the time of
Francis Bacon would certainly show an improving batting average. How
much of the currently accepted set of natural and physical science
theories do you believe is in error? I think the notoriety of failed
theories may be leading you to give them more weight than they actually
possess. For every theory that fails, hundreds are solid as a rock.
And if you actually want to suggest that a group as large as the world's
climate scientists are consistently and sufficiently dishonest to lie to
the public through tens of thousands of peer reviewed journals, I think
this conversation can just end. The suggestion is both ignorant and
offensive. That you knew someone who might have such a moral lack or
that you might have felt such temptations yourself is NOT evidence that
it is commonplace.
"I am also smart"??? Not smart enough, apparently, to realize the very
disappointing impression such a comment gives. Your claim of expertise
is patent nonsense. You are not a publishing climate scientist. You are
not doing climate research. You are not reviewing journal submissions.
You may think you are sufficently knowledgeable to catch "logical
deficits" in research articles, but you do not have the real
qualifications to convince me - or anyone else lacking a denier's
mindset - that you have such abilities. If you believe you have noticed
logical deficits in AGW, please spell them out for us.
IanC said:

It is melting because the world - particularly the Arctic world - is
getting warmer. That is happening primarily due to the Greenhouse
Effect acting on human GHG emissions.
IanC said:
are you using sea ice as a proxy for temperature?
Of course. Local polar air and sea temperatures.
IanC said:
are you testing your climate model predictions?
Ian, neither of us are climate scientists. Neither of us have climate
models. Neither of us have climate model predictions. What test would
I perform by posting pretty pictures of these data on a public message
board Ian? I am using these data to support a contention that the Earth
continues to warm; that AGW did not cease in 1998 as many deniers would
like to argue.
IanC said:

and the other too little.
Then, gosh, I guess I'm glad I don't have any.
The Arctic will
very likely be ice-free in summer in less than 20
years. That is a very signficant loss of albedo and it will have
serious impacts on walrus, seal and polar bear populations. It also
presents a risk to the AMOC which could have global consequences on the
world's sea food supplies. The sea ice in Antarctica is relatively
irrelevant. Almost all of it disappears every summer and, optically, it
is thoroughly overwhelmed by the land-based ice there. That is where
the risk lies. The sub-MSL base of the West Antarctic Ice Sheet
presents the possibility of a horrendous environmental catastrophe.
It's the sort of event whose potential for enormous damage makes it
something to keep in mind even if you think the odds of it occurring are
slim.
IanC said:

temperature and we have only weak understanding of many of them.
That is all perfectly true. Just don't take it to mean that temperature
is not a MAJOR factor, because it is.

What are you trying to say? I have to tell you I am not fond of science
by anecdote and that's exactly what you're feeding us here.
IanC said:

Ignored?!?! What is this Ian?
https://www.google.com/#q=retreat,+glaciers,+1800s. As
often as deniers claim their arguments are being suppressed, you'd think
they might be more cautious of appearing paranoid or trying too hard to
appear the victim. I don't say that I see this coming from you in
particular, but the number of times deniers with whom I argue claim that
this story or this fact or this trend is being suppressed by the mass
media or by some cabal of big name scientists is simply ludicrous.
Particularly when in virtually every instance a simple search yields
mass media references to the "suppressed" factoid hand over fist.
IanC said:

Once again, I don't know what you're trying to say. You may be too
involved in the denier internal dialogue. I'm not privvy to all your
references.
IanC said:

Have I been making some point with Icelandic temperatures or melt rates?
Has anyone? Didn't you just get finished telling us that ice melt is
complex and that we don't yet know all the factors? And, if you're
going to bring up Iceland with comments like that (Mr Smart and
Full-of-Math-and-Science) you might want to think about geothermal
effects. Iceland? MAR? Ya know?
So, quite the ramble. But, are we clear?
1) The very strong consensus among climate experts supporting AGW makes
it extremely likely that AGW is a correct theory.
2) Neither you nor I are climate scientists; we have no models; we have
no predictions
3) I believe the world's ice is melting because the Earth is getting
warmer and that it is getting warmer primarily due to the Greenhouse
Effect acting on human GHG emissions.
