Climate change has been portrayed as a huge catastrophe costing as much as 20% of world GDP, though brave politicians could counter it at a cost of just 1% of GDP. The reality is just the opposite: We now know that the damage cost will be perhaps 2% of world GDP, whereas climate policies can end up costing more than 11% of GDP.
气候变化曾被描绘成一场损失高达全球GDP20%的巨型灾难，虽然勇气可嘉的政要们称能用1%的GDP解决这一问题。但现实情况却恰好相反：我们现在知道损失成本或许是全球GDP的2%，而气候政策最终却可能耗资超过GDP的11%。
