Climate Change and the Integrity of Science

We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular.

[topic sentence. 开宗明义.]

。。。

We urge our policy-makers and the public to move forward immediately to address the causes of climate change, including the un restrained burning of fossil fuels.

We also call for an end to McCarthy-like threats of criminal prosecution against our colleagues based on innuendo and guilt by association, the harassment of scientists by politicians seeking distractions to avoid taking action, and the outright lies being spread about them.

[conclusion。文穷匕见，最后露出了真面目。]

这封信的重点是在呼吁科学家的道德操守的吗？为什么对自己的脑子连这点信心都没有呢，也是怪事。
