Oh Angus you have really bought into the old global warming thing, hook, line and sinker.
Now we face that we lead a style that is taking us to the edge of the cliff in some 100 years. And the way we proceed will not last long.
I find it amazing that a denizen from a country as inhospitable and barren as Iceland, whose people have survived for centuries in a landscape that looks like the moon or somewhere even more inhospitable. Where food is grown in greenhouse complexes which resemble a science fiction version of a base on Mars, should have a such a wholly pessimistic vision of the future. Iceland should by rights be empty of people. Yet there it is, thriving.
You really need to be a little more skeptical of the rubbish being talked about in relation to climate change. Even if you truly believe that we humans are changing the climate in a measurable way. You really must be able to question some of the so called 'truths' we are being constantly fed. It cannot all be true and it's becoming increasingly clear that much of it is to put it frankly, fantasy and speculation. You comment above is a classic of the type. It has no scientific basis whatsoever. It's a pure soundbyte.
Of late, I have been having difficulty finding people who really believe in AGW. It's not as if I spend a lot of time with gun toting, cigar chewing, right wing conservatives either. If I bring up the subject it's usually in a neutral even joking manner. I have been surprised at the intensity of the comments made against the global warming issue. Even those who you might expect to believe in it express skeptical views and often declare that at least it will reduce pollution. This ignores the fact that CO2 is not a pollutant as such.
The fact is that the global warming lobby has overplayed it's hand. The truth if it's there is lost in a sea of hype. 'You can't fool all of the people all of the time' as a famous man once said. That's what's happening now.
A bit of skepticism would do you no harm.
