No.
It is, shockingly, specefic only to... changes.... in climate.
Incorrect. And something I didn't even realize until I read through the peer review comments in the latest released IPCC report and stumbled upon one of the reviewers stating this fact, with the response being that the IPCC defines it differently. I then did some research and found this. Actually, that's not the page I originally found, but I forgot to bookmark it and found this one which says the same thing. Specifically:
UNFCCC definition of Climate Change wrote:
"Climate change" means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
IPCC definition of Climate Change wrote:
Climate change in IPCC usage refers to any change in climate over time, whether due to natural variability or as a result of human activity
Want to reprise your "no" position on this? The ramifications of a political interpretation of a scientific body of work which uses a changed definition of the main body itself is pretty staggering.

Which is the exact argument Joph attempted to make the last time I pointed this out. Of course there's no papers on climate change that talk about non-human causes.
There are thousands.
I'm specifically talking about when he quoted this page, specifically quoting this section:
Quote:
The drafting of such reports and statements involves many opportunities for comment, criticism, and revision, and it is not likely that they would diverge greatly from the opinions of the societies' members. Nevertheless, they might downplay legitimate dissenting opinions. That hypothesis was tested by analyzing 928 abstracts, published in refereed scientific journals between 1993 and 2003, and listed in the ISI database with the keywords "climate change" (9).
The 928 papers were divided into six categories: explicit endorsement of the consensus position, evaluation of impacts, mitigation proposals, methods, paleoclimate analysis, and rejection of the consensus position. Of all the papers, 75% fell into the first three categories, either explicitly or implicitly accepting the consensus view; 25% dealt with methods or paleoclimate, taking no position on current anthropogenic climate change. Remarkably, none of the papers disagreed with the consensus position.
Admittedly, authors evaluating impacts, developing methods, or studying paleoclimatic change might believe that current climate change is natural. However, none of these papers argued that point.

So. They tested whether the IPCC was being selective in their choice of scientific papers upon which to base their recommendations by looking through the ISI database by searching using the keywords "Climate change", and they find it "remarkable" that none disagreed with the consensus position (that humans cause climate change).
Um... Duh. Cause all the scientific papers are submitted using the UNFCCC definition, which means that in order for your paper to fall under the heading of "climate change" you must be looking at human impacts to climate to some degree.
The last paragraph I quoted is particularly amusing once you realize this. Um... of course none of those papers argued that point. Because by the definition those papers are using, that's not "climate change".
Get it yet? The whole issue is smoke and mirrors. The IPCC is playing word games with science. There's presumably a whole body of work out there about changing climate states. But none of those papers will be filed with the ISI as "climate change".
Can you be more provably wrong on this?
