Global warming may or may not be the great environmental crisis of the 21st century, but￾regardless of whether it is or isn't - we won't do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed. A1 Gore calls global warming an "inconvenient truth," as if merely recognizing it could put us on a path to a solution. But the real truth is that we don't know enough to relieve global warming, and - without major technological breakthroughs - we can't do much about it. From 2003 to 2050,the world 's population is projected to grow from 6.4 billon to 9.1 billion ,a 42% increase. if energy use per person and technology remain te same, total energy use and greenhouse gas emissions(mainly,CO2)will be 42% higher in 2050.But that's too low, because societies that grow richer use more energy. We need econmic growth unless we condemn the world's poor to their present Poverty and freeze everyone else's living standards. With modest growth, energy use and greenhouse emissions more then double by 2050. No government will adopt rigid restrictions on economic growth and personal freedom (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.
