That would have been the 1970s and 80s. They found that no one would listen to
them until they started hamming it up for the press.

Two out of three ain't bad.
The vast majority of scientist just do the science to the best of their
abilities and no one hears anything about it expect the people that read the
Scientists tend to be thinking people and a number of them realise that the
implications of their work involves significant impacts to their lives unless
something is done, and that nothing was being done. A small minority of these
have been willing to step forward and engage in the political process.
These scientists engage in political and manipulative communication to try and
tell people about their science because of the implied impacts to the society
that the scientists are a part of.
When the reason for the political action is because of the science then I
contend they are still acting as impartial scientists. (If the political
action was for other reasons and the science was being used to support those
reasons then they are no longer acting as impartial scientists).

Most scientists (not just climate) are fairly passionate about their work and
I have doubts about how truly objective they are. That is why the system of
peer review is so important in the scientific process. If you exclude anyone
from contributing in a field if their objectivity is suspect you will shut
down most science.
Your underlying premise is that the scientists are engaging in public debate
to support their sources of continuing funding. My experience is that they
engage in public debate because the science drives them to it.
The solution to your problem would be to change the funding model so that good
science which contradicts climate change is more likely to attract funding
than science which supports climate change.
You do realise that the major sources of funding for climate change science
has been governments (including Australia and the US) who would very much like
evidence that refutes climate change and the reason they haven't been funding
"climate stability science" (can't think of a good term for it just now) is
because there isn't any _good_ science (from an objective point of view) that
supports climate stability.
The science that gets funding tends to be about resolving the uncertainties in
climate change, including proving it isn't happening if it isn't. The science
is showing again and again that change is happening. There are still a lot of
uncertainties but mostly about how bad it will get.

A non sequitur. The cause of ignition is irrelevant to the conditions which
make it more likely to spread.

Another non sequitur.
The movement of carbon within the biosphere has no net impact. It is only the
introduction of additional carbon to the biosphere that has any consequence.

Those are three big ifs.
Not at all my field but the figures in the scientific literature seem to be
about 3 orders of magnitude smaller.
The Australian Academy of Science Q&A on climate change
http://science.org.au/reports/climatechange2010.pdf (linked from
http://science.org.au/policy/climatechange.html ) states:
The combined annual emissions from volcanoes on land and under the sea
averaged over several decades are less than 1% of CO2 emissions in 2009 from
fossil fuels, industrial processes and deforestation.
I'm happy to rely on the experts.

You can never blame any single event on global warming. Global warming changes
the probability of events - it doesn't cause them. What used to be a one in
100 year fire/drought/flood may become a one in 50 year or one in 10 year
event after climate change. That's what climate change is.
Have another look at the quote you start with:
" A trio of scientists say the scorching heat, high winds and bone-dry
conditions fuelling catastrophic wildfires in the US offer a preview of
the kind of disasters human-caused climate change could bring.
"What we're seeing is a window into what global warming really looks
like," Princeton University's Michael Oppenheimer said.
"It looks like heat, it looks like fires, it looks like this kind of
environmental disaster... this provides vivid images of what we can
expect to see more of in the future." /Quote
They are not saying this event was caused by climate change. They are saying
climate change makes the conditions that fuelled this event more likely.

Again not my field :-) (although I do have a degree in Economics).
Again a non sequitur.
The quality of policy responses to climate change make no difference at all to
the reality and science of climate change.

You could probably say the same about defence spending penalising the
Australian economy and negative impacts of foreign policy as it pertains to
fiscal policy. Although the impact of defence spending on the economy is
probably a couple of orders of magnitude greater than that of climate change

Will the sky also fall if the threat model used by defence to determine its
spending is wrong?
