Are you going to answer my other question? (repeated below for
ease of reference)

Is there *any* evidence/argument that would convince you
that climate change is an *imminent* problem? I emphasis
*imminent* to avoid the possibility that you'll only be convinced
after it is too late to mitigate the effects.

*If* there is no such evidence/argument, then there is no point
in having a discussion with someone with a closed mind.


And what evidince or argument is needed to convince you of the
opposite? Perhaps closed minds call the kettle black?

There are a number of things that would do it:

* evidence that the cloud models seriously understate the amount of
cloud that will form as the global temperatures rise
* someone finally figuring out a way for cosmic rays to produce the
clouds the proponents think they do
* the discovery that satellite measurements have under-reported
incoming energy
* adding more measurement stations to the sparsely instrumented
polar regions determines the warming there is much less than
previously estimated.
* a new theory, supported by measurements, the CO2 forcing is
significantly lower than current theories require
* a study demonstrating each method used to determine sea level rise
has flaws widening the error bands significantly.
* deep sea measurements showing the ocean circulation currents are
much different than thought, requiring significant changes in heat
transfer and dissolved CO2 parameters.

A climate scientist, or even a knowledgeable lay person, could name a
lot more, of course. There are a lot factors in climate dynamics, so
there are many places a person can look for potential errors in theory
and measurements.
