In other words, if Barroso fears costs of 20% of GDP in the year 2100, the 0.5% payment every year of this century will do virtually nothing to change that cost. We would still have to pay by the end of the century, only now we would also have made ourselves poorer in the 90 years preceding it.
换一句话来说，如果巴罗索担心在2010年的时候损失20%的GDP，那么，本世纪每年0.5%的花费根本无济于事。而我们还是要在本世纪末的时候支付这一代价，只是我们是在前九十年把我们自己搞得更穷而已。
