Your education in engineering does not make you an expert in analyzing climate change any more than it disqualifies you from doing so. Engineering is a field of applied science. I'm sure you have an excellent grasp of many scientific concepts applicable to engineering. I'm also sure that gives you a better platform to understand the discussion, in so far as it is carried on in the jargon of science, than most.So are you suggesting that my degree in Engineering makes me fully qualified to judge fully the scientific merit of climate change suppositions? If you think yes, then my word as a scientist is that AGW is a better theory than any other ones out there. If not, why would a guy who studied quantum mechanics in the 60's have any relevance to the discussion?
Simply put, if you don't have the time or ability to fully research the issue, it makes sense to listen to the people who actually spend their lives studying it and a clear majority of scientists who actually study the material agree that human CO2 has had a significant impact on climate.
As I understand it, the study of climate change is also an application of a number of scientific fields of study. I'm also sure that someone will tell me that my list is incomplete, but it would seem to require the application of expertise in the disciplines of physics/astrophysics, geology, biology, and chemistry (to name just a few). I'm reasonably sure that a world class physicist is qualified to criticize the application of physics principles to climate change analysis. Likewise, the opinion of a world class geologist, etc. There is no higher scientific authority derived from the posture "But I apply my knowledge to the study of climate change exclusively!". Working within a team of scientists focussed on a single issue may give you greater insight as to the integration of scientific explanations for what is observed, but if you've made a mistake in your science, you've made a mistake, simple as that.
I have neither the time nor the inclination to get a post graduate degree in one or more of these fields just to verify the opinions coming out of various scientific camps. However, I've invariably found that if someone who is highly intelligent and understands their field well enough is also motivated enough, it's always possible for them to explain their position in a way that any intelligent person can understand. When that happens, often what gets revealed are basic logical errors, buried miles underneath technical jargon, like detritus beneath an advancing glacier.
Ball's presentation at least meets the standards of clarity I'm prepared to spend my time considering. His logical errors, if they're present, are not apparent to me. Point me to someone of equal clarity who can point them out.
