If we decrease the particulate pollution problem, which improved health,
AGW gets worse not better.

Dimming wasn't invented recently.  It has been around in atmospheric
science for a long time and there's been a lot of work to estimate the
magnitude of it's effect.  According to the consensus of actual climate
scientists it is significant but not near big enough to counteract
increasing CO2 concentration.  Several large volcanic eruptions over the
last century that temporarily add massive amounts of particulate matter to
the atmosphere been observed to cause downward pressure on the temperature
record and provide another way to test estimates of the magnitude of
dimming.  Artificial increase of particulates has been proposed as way of
countering AGW.  Global warming over the last century is empirically
verifiable from temperature records and is remarkably robust when the major
"noise" effects of insolation variation, volcanic eruptions and ENSO are
removed from the temperature record using multivariate correlation.
Dimming has demonstrably failed to stop AGW though it will have attentuated
it.

The TV program you mentioned has been discredited. Google it.  The idea
that something is credible because it's been on TV is a joke, right?


However, if you want to believe that the overwhelming majority of actual
trained climate scientists are a bunch of idiots (or conspirators!) who
have been gazumped by a handful of loud mavericks who have incidentally
been demonstrated to be statistically incompetent, not understand basic
physics, make stuff up, and in cases are unable to add and multiply numbers
or even read accurately, then go right ahead.


BTW (if anyone's still reading) a set of simple clear responses to Ian
Plimer's "How to get expelled from school" climate questions can be found
at the climatechange.gov.au site. I found this worth reading just to be
reminded of the level of incompetence, fantasy, and/or dishonesty that
exists in anti-AGW circles.
