California senator Diane Feinstein argues that we should curb carbon emissions because the Sierra snowpack, which accounts for much of California’s drinking water, will be reduced by 40% by 2050 due to global warming. What she fails to tell us is that even a substantial reduction in emissions – at a high cost – will have an immeasurable effect on snowmelt by 2050.
加利福尼亚州参议员费恩斯坦说，我们应当限制二氧化碳排放，因为加利福尼亚饮用水源大多数来自于积雪，而这些积雪到2050年的时候将会由于全球变暖而减少40%。但是她却没有告诉我们，即使以高昂的代价大幅度减少排放，到2050年的时候对积雪融化的影响还是无法衡量。相反，我们或许应该投资于水储存设施。
