You are rather backed by your opinions and guesses ABOUT science... Now those opinions might be reasonable and the guesses could be educated... but they are not science.
They are not "opinions" or "guesses". They are probabilities, backed by a great deal of evidence - like virtually everything in science. Higgs Boson existence? Probability. The Big Bang? Probability. Quantum mechanics? Yeah, a lot of that. To be scientific, a theory does not have to be a certainty at all; the probability just needs to be carefully quantified, and backed by observation and/or experiment.
...you have overstated your reasonable degree of confidence on issues for political gain. This has been done repeatedly which is why many of the IPCC reports have come under such savage criticism
Citation needed. The IPCC reports all state their conclusions in probabilities, which are carefully quantified, and are backed by citations of peer-reviewed studies at every stage. The vast majority of the evidence presented in the IPCC reports has proved under very close examination to be solid (NOT absolutely certain, but of sound scientific methodology). This is why they are accepted as, not the gospel truth, but the best information on the subject that we have, by every major scientific institution and government, as well as by the great majority of scientists (and nearly all climatologists).
It is THAT which is ultimately causing most of the controversy. Not the science but rather the political solution to the science.
I do agree that this is the source of the controversy. Solutions are indeed often political, but unfortunately all too often, peoples' political views about some of the solutions contaminate their views of the science, which usually leads to claims that the science itself is being politicised. I disagree with that.
Or you must sit down and talk about solutions we can all find palatable.
If only we could do that. Unfortunately, there are still far too many strident voices still trying to undermine the science, which blocks any reasonable discussion of solutions. If those voices actually had any peer-reviewed evidence of a quality that could convince a reasonable number of experts, that would be fine, but sadly these dissenting voices tend to rely on volume instead.
I'm also of the opinion that many people misunderstand the solutions that have been proposed (for example, see all the claims that a phased transition to a carbon-neutral economy would be a disastrous burden on society, whereas many economists are seeing it as an opportunity for actually reducing the many existing external costs of carbon emissions).
