### Using social criteria in deciding who to trust is only useful if
you do not have a technical analysis of the issue at hand. All truth
is at first a minority belief, and many common fallacies eventually
end up the same, so whenever you encounter vehement factual
disagreements between large groups of people you must use a technical
understanding as your most important source of knowledge.

### Yeah, he is. And Alley is crazy, while Mann is an all-out crook.
He used to work in Charlottesville where I live, and the state
attorney is now trying to find out exactly what happened to the
substantial funds he burned through while working for UVa.

### The north pole is either not warming at all, or else it is warming
very, very slowly. The huge red splotches on GISS reconstructions are
not supported by any data - GISS does not have thermometers in the
area, which perhaps why they feel they can go wild and invent +4C
temperature deviations. Same pertains to the Antarctic. "Watt's Up
With That" has a few discussions of the UHI specifically in the
Antarctic - turns out that GISS and UAH have been using a thermometer
on the Antarctic Peninsula which now is surrounded by a landing strip
that is kept snow-free year round, and produced significant spurious
warming, while other thermometers which did not yield results
confirming GISS' foregone conclusions, are simply disregarded.

BTW, rural temperatures all over the world, insofar as they are
actually available, have remained almost constant and the US is not an
exception. This is the main reason why I reject the global warming as
bad science (i.e. science completely polluted by special interests).

### No, we have good data already. We know that plant mass will
increase by 40 to 80%, based on many indoor and outdoor CO2
supplementation experiments. We do not know yet how this change would
impact e.g. the amount of evapotranspiration, albedo, and the
concentration of VOCs emitted by plants (at least I haven't found such
data in published literature), but these are separate issues from the
generally good news about plant mass.
