Global Warming: Questions That Need Distinguishing – Maverick Philosopher

I like to share posts that give examples of what I think is objective thinking. Below are some extended quotes from Maverick Philosopher about global warming that provide an example.

I am a skeptic about global warming (GW). To be precise, I am skeptical about some, not all, of the claims made by the GW activists. See below for some necessary distinctions. Skepticism is good. Doubt is the engine of inquiry and a key partner in the pursuit of truth.

A skeptic is a doubter, not a denier. To doubt or inquire or question whether such-and-such is the case is not to deny that it is the case. It is a cheap rhetorical trick of GW alarmists when they speak of GW denial and posture as if it is in the ball park of Holocaust denial. People who misuse language in this way signal that they are not interested in a serious discussion. When GW activists speak in this way they give us even more reason to be skeptical.
I have not investigated the matter with any thoroughness, and I have no firm opinion. It is difficult to form an opinion because it is difficult to know whom to trust: reputable scientists have their ideological biases too, and if they work in universities, the leftish climate in these hotbeds of political correctness is some reason to be skeptical of anything they say. (Both puns intended.)

Off the top of my head I think we ought to distinguish among the following questions:

1. Is global warming (GW) occurring?
2. If yes to (1), is it naturally irreversible, or is it likely to reverse itself on its own?
3. If GW is occurring, and will not reverse itself on its own, to what extent is it anthropogenic, i.e., caused by human activity, and what are the human causes?

(3) is the crucial empirical question. It is obviously distinct from (1) and (2). If there is naturally irreversible global warming, this is not to say that it is caused by human activity. It may or may not be. One has to be aware of the post hoc ergo propter hoc fallacy. Suppose there is a close correlation between global warming and man-made carbon emissions. It doesn't straightaway follow that the human activity causes the warming. But again, this is not a question that can be settled a priori; it is a question for climatologists.

4. If anthropogenic, is global warming caused by humans to a degree that warrants action, assuming that action can be taken to stop it?
5. If GW is caused by humans to an extent that it warrants action, what sorts of action would be needed to stop the warming process?
6. How much curtailment of economic growth would we be willing to accept to stop global warming? And what other effects on human beings could the anti-global warming policies be expected to have?
The first three of these six questions are empirical and are reserved for climatologists. They are very difficult questions to answer.

Our first three questions are empirical. But the last three are not, being questions of public policy. So although the core issues are empirical, philosophers have some role to play: they can help in the formulation and clarification of the various questions; they can help with the normative questions that arise in conjunction with (4)-(5), and they can examine the cogency of the arguments given on either side. Last but not least, they can drive home the importance of being clear about the distinction between empirical and conceptual questions.

Just for the record I too am a skeptic or, to be more specific and accurate, a “luke-warmer” which means I think we humans have some impact on the global climate but nowhere near what global warming alarmists claim. It would take many pages to explain why I believe this.
