Of course it's about saving human life, but money is a scarce resource by definition. Every penny spent on addressing carbon emissions represents an opportunity cost against lives saved elsewhere. Not just AIDS research, how about the 10 million who die each year due to the lack of clean drinking water - a cheap and easily solveable problem?
The money spent on reducing carbon emission could be used very cheaply to save lives right here and now, it's just not as trendy.
For a science/engineering/IT audience, I'd expect more enthusiasm for measurement of cost/benefit.

I'd forgotten the socialist utopia of 3 day weeks, British Rail, air-travel only for the rich, British Leyland, dole queues, a single broadcaster, and the winter of discontent.
Analysis of the increase in performance and deliverables to the customer and tax-payer doesn't support your argument, e.g:
1. British Rail was so bad, they didn't even measure delays. Rail travel is faster, safer, cheaper (don't forget the massive taxpayer subsidies under BR). Yes, it's still crap, but only because we expect more than ever before.
2. Arts subsidies - You mean the money paid to elitist activities such as the ballet and the opera? An event that so few people want to go to that they cannot survive without the rest of us clubbing together to pay for it! Shakespear, Mozart, Dickens, Hardy were all commercial artists. What are you proposing, that committee's of people with the 'correct' opinions (remarkably similar to your own, obviously) get together to decide what the rest of us should see. Just think of the dross produced by the British Film Industry that we've all paid for and compare that to the vibrant and (often) better quality independent works produced without subsidy (Shaun of the Dead, anyone?).
3. You show your true colours in your irritation with allowing anyone to express analysis other than your dogma - "One question, why is El Reg suddenly posting so many - shall we be kind? - counter-arguments"
Economists (including the ASI) recognise the concept of social goods (defence/healthcare/anti-monopoly action) but look to determine the ost efficient way of achieving societal objectives. Attempting to measure costs and benefits empirically seems to get the lefties all in a steam (well, only when the facts contradict your theories). You seem to make a leap that if the facts don't agree with your opinion, the facts are wrong.
