Reply #13: Am I reading that expense number right?

[tk2kewl]

"nvolve the huge expense of 1 per cent of global GDP (£0.3trn)"

£0.3 trillion = £300 billion = $570 billion

Haven't we spent over $300 Billion in Iraq alone, and wasn't our budget deficit about the same?

Developing the technologies needed to prevent catastrophic climate change would certaily be something worth going $570 Billion in the hole for.
