In reply to Bruce Hooker:
> I think you are being over pessimistic here, but in doing so it is not your fault we are all being told to react like this, it is possible to resist though.
It is possible. Some climate-change scientists (loose description I know, they all have individual specialisms), have worried that the tone of "climate change propaganda" is too uniformly gloomy, inducing a sense of fatalism. A bit the horns of a dilemma, you have to paint the story in dramatic primary colours to get the attention of politicians/the public, but if you over-do it, they think "what the heck? we're doomed anyway, so why bother?"
There is also a lingering scepticism, you, like me, are probably old enough to remember the "Club of Rome" and confident predictions, with graphs, statistics and the like, showing that complete resource exhaustion was inevitable by 1975. So while the evidence for Global Warming seems very strong and getting stronger by the day, apart from anecdotal evidence (like this so-called Winter we are having!), there is good reason to be sceptical about even the most confident of predictions.
> Mankind has made enormously enormous progress over the last couple of centuries
Well certainly technological, I'm not sure about otherwise. I think it was a play by GB Shaw that included the Syphnx as a character - when one of the other characters was enthusing about progress, the Syphnx cynically remarked :
"Well I've been here 7000 years, and I can't remember much progress!"
> Population is the main problem... if the figure I heard is optimistic, although it was agreed to by a panel of several rather calm French specialists, who may not be wrong, then all the more reason to address this fundamental problem.
I agree that population is a very important, possibly the MOST important issue, but I'm not so optimistic as you are. Not least because of some of the gross demographic distortions, huge population increases in the third world (I think that Algeria's population has increased by something like 400% in 50 years), while Western European (Native) populations are almost static in terms of birthrate, but swelled by greatly extending life-span. This severely compounds the demographic imbalance, especially as the populations (Western) are desperate to cling to the retirement ages, social benefits, etc, they have become used to.
> You will have noticed that this doesn't seem to be in the news much, nor be the favorite subject of the pseudo ecological doom and gloomers
There certainly is a sort of personality type that seems to relish the thought of catastrophe, even if the threat has to be invented/grossly exagerated, for all sorts of dubious motives. But remember, although the little girl kept crying "Wolf", the wolf did finally arrive.
