- Well, *now* we're talking.

- Dave:
- >Only if one *knows* it's inadequate, and in this case we don't...
-
- Mike:
- >I thought we already agreed that we do!
-
- I don't think so.
-
- Dave:
- >As I've shown above, [reasonable measures] *would* be a constructive use of
- >resources.
-
- Mike:
- >I did not see a convincing cost/benefit analysis.
-
- I don't have one, but I agree that one would have to be done before the
- decision was made. At this point, though, we have to agree that *if* we can
- identify low-cost, low-impact ways to reduce emissions, that we'll take them
- even if they aren't likely to solve the entire CO2 problem. Is that not
- worth pursuing?
-
- >What is proposed? What would it cost?
-
- I can't answer those questions, I'm just a concerned citizen. I'll leave it
- to experts in the field to exhaustively enumerate the possibilities and their
- associated costs. Obvious measures include conservation, nuclear/solar/wind
- energy, a higher gas tax and/or CAFE, mass transit, and telecommuting.
-
- >Are there really likely to be any benefits?
-
- Sure. Money will be spent on R&D and consumers will buy new products.
- Conservation is a Good Thing outside of reducing just CO2 emissions--all
- power production related problems are likewise reduced.
-
- >Other than learning that a 2% reduction can hardly be measured, much less be
- >considered to have any significant short term or long term impact.
-
- We'll also learn exactly how hard it is to reduce emissions, which may be
- handy information if we get clear evidence that further reductions are
- necessary.
-
- >How much will we pay to learn that it didn't make any difference?
-
- But even if we don't measurably reduce atmospheric CO2, there will be other
- benefits, as I've already mentioned.
-
- >How much will we pay so that a CO2 level of 3.195% will be reached
- >in July, 2022 instead of June, 2022?
- >
- >Who has that signature with a statement about numbers?
-
- These numbers are available, it's just outside of my area of expertise. I'm
- confident that there are *some* measures we can easily afford. That they
- won't solve the whole problem doesn't mean we shouldn't enact them. That
- right there is my entire point in this thread. John Moore started by saying
- we have two choices: do nothing, or take drastic measures. Although I
- personally support drastic measures, I realize they won't happen until
- there's irrefutable evidence of the dangers of CO2 emissions, so I propose
- taking the middle ground. You argue that the middle ground won't solve the
- problem, so why bother? I argue that half a dose is better than no dose. If
- you disagree, then what more can I say?
-
- Dave:
- >If we take reasonable measures and they have no impact, we're no worse off
- >than if we take no actions.
-
- Mike:
- >Only if the "reasonable measures" have zero cost.
-
- Only if they have no other positive effects, which they certainly will.
-
- Mike:
- >How much do "reasonable measures" cost?
-
- They're affordable, by definition of "reasonable". If we can't agree that
- the cost/benefit analysis is favorable, we won't do it.
-
- Dave:
- >Remember Pareto's Rule--the first 90% of excess greenhouse gas emmisions
- >will likely be cheaper to cut than the final 10%. Let's at least go after
- >the cheap/easy ones.
-
- Mike:
- >Do you really think that a 90/10 "rule" has any significance in this context?
-
- I don't know if the numbers 90 and 10 will hold, but the fact is that the
- first X% will be easier than the next X%. We *will* solve the cheap/easy
- problems first.
-
- >Are there any cheap/easy [way to reduce CO2 emissions]?
-
- Yes, relatively speaking. Conservation and CAFE/gas tax will certainly be
- cheaper than, say, replacing all fossil-fuel steam plants with nukes.
-
- >How 'bout fleet MPG to 40? Is that cheap/easy?
- >Isn't that what Clinton proposes? Or was it 45MPG?
-
- Yes, I think a CAFE increase *is* relatively cheap and easy. No, I don't
- know the dollar cost of raising the CAFE by N%, but, yes, I would want to see
- some numbers before "I" signed it into law.
-
- >Why not just raise gasoline prices to $4/gal over a period of time
- >and let the market take its course? Seems "easy", is it "cheap"?
-
- Don't know, but that's a good question... better than "why do anything if we
- can't do everthing?"
