Nicked from elsewhere ...
I think that the effect of humans on this planet is vastly overimagined, when you consider how long the planet has been here.
Age of planet: 4,500,000,000 years ago.
Life on earth: 3,800,000,000 years ago (apprx).
Mankinds industrial age: 300 years ago.
So you are asking me to believe that one species, can lay waste to a planet in 3,800,000,000 / 300 years ? I certainly believe that one species can lay waste to itself in that time, but that's not "climate change".
The climate changes all the time. 2,000 years ago the Romans grew white grapes in Yorkshire. Try doing that now. 300 years ago the Thames froze over every winter. 10,000 years ago you could walk from Spain to Scotland - and we know people did. Try that now.
Even the experts admit climate change is truly chaotic. Which means you can't factor in or out anything mankind does.
Incidentally, there is NOTHING wrong with wanting to live in a more sustainable way. It's something we should be putting all our effort into. Not because of climate change though. Just because it's more sensible in the long run.
One day, someone will write a book, or make a film. It will start with the idealism and hope after the second world war. It will chart how well meaning, sincere folk started to realise that we can't just rape the planet and not pay. These evolved into the counterculture of the 60s, which were derided, mocked and ridiculed by mainstream society.
Then, somewhere between the 60s, and the 90s, a sort of critical mass was reached - maybe the 1984/5 Band-Aid/Live-Aid phenomenon ? Either way, somehow, people in suits with wire-rimmed glasses and red braces had an epiphany. They realised you could actually SELL being green. You could slap the word "organic" on a food and double the price. So they did.
What was brilliant about this, was that it was the environmentalists that were effectively paying for the marketing. Every Greenpeace ad about the environment would see a jump in sales of "Eco" this, and "Green" that.
And our lords and masters looked upon this, and they saw it was good.
And thus it came to pass that the 1980s misbred young executives that were heavily advertised became the advisers and policy consultants of the 90s.
And lo verily, did the notion of "Green taxes" be dreamt up. For they did see, that whilst Joe Public might be narked about an extra penny on income tax, the same Joe Public would queue up to "save the planet".
I'm sorry, but personally I think the worlds public have been hoodwinked on a massive scale. "Green energy" is a good example. It's doing fuck all for the planet (in fact it's a net carbon contributor) but it's doing wonders for the firms that build the kit, and wonders for the upper-middle classes who actually get paid up to 40p/unit for the electricity that they put into the grid which is charged at 10p/unit.
Everyday I see many small things that could save a shed load of energy. Very simple things. But guess what ? There's no money in it for anyone, so it's ignored. Which leads me to my view of life. "If it really mattered ..."
If reducing emissions really mattered, you'd have a planning and tax system which encouraged work from home, and staggered working hours. That would cost very little, but - guess what ? No money in it. In fact you'll find behind the scenes the road and rail lobby would HATE any idea like that. So it's left alone.
When the government acts like it matters, then I will.
What I find particularly depressing, is people who are a victim of bad science in one area, appear to be willing to fall for it in another.
I manage to avoid long debates on climate change now, by just saying: "Define climate. Define change".
FWIW I have a more Gaian view of things. We live in a symbiosis with everything on earth, including the Earth. And just like a body with an infection, if we start to make the Earth poorly, then it's immune system will start to kick in to eradicate us. Or, alternatively, like a cell about to divide, we somehow manage to become 2 cells. But that requires interplanetary travel on a scale way beyond out capabilities. Especially if our offspring are more content to watch Celebrity Big Brother rather than design a better mousetrap.
Here endeth the rant for today :)
