如果你想去了解的,试着搜搜我提的问题。从你贴的这两段看来,背景知识差的实在太
远,不要摆出姿态来科普的样子。
气候变化这个话题,不应该成为版上政治斗争的牺牲品,不过我也没胃口来科普。借
milo的逻辑,有的右右在这件事上的无知和傲慢不值得我花时间去教育。就像生活中的

你好像暗示人类活动所影响的CO2百分比较小,所以人类活动造成的GLOBAL CLIMATE
CHANGE的后果就不大?
这是不对的,因为人类和生物圈对哪怕细微的CO2/气候变化也会比较敏感。
一个例子,人正常呼出的空气大概含4% CO2,这个比例听上去也不高,但是如果大气中
CO2水平升高到哪怕1%,人就已经中毒了。

the pipes are plumbing venting system. For water to drain freely out of a
house waste system, there must be adequate venting. The venting performs
three functions. It allows air in front of the water rushing through the
waste pipe to be
pushed out of the way, and it also allows air to be reintroduced to the
waste piping after the water has gone by. Lastly, it allows sewer gases
to escape outside through a vent stack.
