Let's first understand the nature of the controversy. There are some
who deny that there is a strong anthropogenic component to global
warming. Once we establish the scientific vacuity of said position, we
may wonder as to the impact of the observations that the global
climate is warming and that we as humans share a large responsibility.

Nope, climatologists however can look at what would happen if the CO2
emissions continue to add to the air concentrations and its historic
impact on climate as well as model its impact. Of course, such models
become 'less' reliable over longer times, especially when predicting
specific impacts on a particular country for instance. However, global
temperatures are a statistical average which removes some of the
problems to which David alludes. How familiar is David with the
current state of climate and weather modeling?

Climate modeling is surely less mature than biological evolution but
one should be careful to therefor reject its relevance. David raises
good questions and I am certain that the answers can be found by
researching the relevant literature and understanding the many many
contributors to the IPCC report for instance.

I'd say that while evolutionary science may go back to Darwinian days,
our real understanding of genetics is more recent than our
understanding of climate and I do not think that comparing the two is
unreasonable. In many ways both have found that the complexity of
life/weather is far more intricate than one may have imagined only a
few decades ago. Genetics was given a strong push by science's
abilities to unravel the code and pursue unraveling the code amongst
common species. Climate modeling got a major push from satellite
observations, especially over the oceans, adding significant knowledge
and data. In other words, both are in many different senses,
relatively young sciences. Climate research also involves many other
sciences such as for instance geology, dendrology, ice cores etc. All
providing relevant data to resolve the ambiguities that are so typical
in science.

Nor it is unreasonable to point out the many similarities between
evolution and climate science when it comes to politically or
religiously motivated (and well funded) opposition. Both seem to use a
well tried approach of cherry picking, equivocation and a certain
appeal to our ignorance as evidence.

Skepticism is good if it leads one to do more research, skepticism
should never be the end point.
