- 9 -14 modest growth,energy use and greenhouse emissions more then double by

2050.

No government will adopt rigid restrictions on economic growth

and personal freeom (limits on electricity usage,driving and travel)that might cut back global warming.Still,politicians want to show they're "doing something"Consider the Kyoto Protoco(京都议定书).It allowed countries that joined to punish those that didn't.But it hasn't reduced CO2 emissions(up about 25% since 1990),and many signatories(签 字国) didn't adopt tough enough policies to hit their 2008-2012 targets. The practical codusion is that if global warming is a potential disaster,the only solution is new technology.Only an aggressive research and development program miaght find ways of breaking our dependence on fossil fuels or dealing with it. The trouble with the global warming debate is that it has become a moral problem when it's really an engineering one. The inconvenient truth is that if we don't solve the engineering problem, we're helpless. 57.What is said about global warming in the first paragraph?
