That's not deductive reasoning...That's the post hoc ergo propter hoc fallacy.Here's my theory, this is before reading the thread by the way.
Most people in this thread have invested their belief system in science. They believe they have done significant research (which 99% of them haven't because they lack either a) the intellectual capacity b) the funds c) the time d) some combination of a, b and c) and ignore the fact that most of the research they accept is based on whether the researcher's point agrees with them.
"Peer review" doesn't mean anything. Neither does scientifically proven or accredited by... You have no idea who the peers that reviewed something are and you know jack squat about the references, backgrounds or character of the people whose articles you're reading. I'm not against science, I am against the scientific community. I do believe that they are for sale and I have a close personal friend in the research community who has, on multiple occasions, demonstrated how the scientific community works. It is driven by money and ideology. Many scientists are like politicians in that they get into the business with pure motives but over time they are corrupted by the need for funding for their projects.
With all of that, I will make a suggestion. Instead of quoting scientists, why not look at the journals/articles look at the questions that you are trying to answer. Next, try to find holes in the theory. Stop advocating this study and not that one and look at the actual data because there is absolutely nothing scientific about "scientists say so"...

... or you could use plain old logic and deductive reasoning.
The infra-red absorption properties of CO2 and other gases are scientifically well-documented.
The concentration of those gases in the atmosphere has been going up, since the advent of the Industrial Revolution.
Therefore, if the trend continues, more infra-red energy and, therefore, more heat will be reflected back towards earth.
Wrong, that IS deductive reasoning. You'd only be correct, if there were no established link between CO2 and IR radiation! What part of my logical syllogism* do you think has a flaw? Statement #1 is true. Statement #2 is true. Statement #3 follows logically from 1 & 2. Where's the problem?!?!
*- A syllogism (Greek: συλλογισμός syllogismos "conclusion," "inference") or logical appeal is a kind of logical argument in which one proposition (the conclusion) is inferred from two others (the premises) of a certain form, i.e. categorical proposition.
