简介

如果大气中最大限额CO2含量是350单位/百万,可如今已经是385,那么仅仅减少CO2排放率是否合理?简单说,是否所有针对减排的策略都如同将泰坦尼克号甲板上的椅子重排?
或者按照逻辑来说,我们是否必须尽快从大气中去除CO2?我们能否尽快将大气中CO2减少10%来避免全球气候紊乱?
在2007年,大气中CO2已含385单位。可是我们并没有听到任何关于“转移重心”的谈话,也没有任何在全球范围内为了保持生态平衡而去除CO2的行动。历史证明了过度逾越限制无疑带来悲剧的结果:死亡和生态系统坍塌。这难道是我们想要的将来?
如果不是,我们已经学会如何完全准确地给CO2“标价”。如今,我们趋于用扭曲的方式标价CO2来得到我们想要的:廉价能源。最终,如果我们 “烧了书”,结果肯定会“烧死我们”。

Take pills, don’t change your lifesyle!

Why Dick Cheney told us that “our life style is not negotiable“. But at what price, Mr. Cheney?
We have been well trained to think that there is no need to change our life styles because it is simpler and easier, better, more American, just to take a pill to fix our problem. [...]

Biochar Notes: Links and pointers

Here’s the question: If the maximum “safe” level of CO2 in the atmosphere is 350 parts per million, but today’s level is ALREADY 387 ppm, is it “good enough” to simply reduce the rate at which we are adding CO2 to the atmosphere? Simply put, is any policy option limited to a [...]
