Hint:
Volcanic
When they found Missy's essay in the estate sale forty years after the fall of civilization, people laughed that Missy had written about how society found global warming to be equivocal. That such a developed society could make such erroneous conclusions caused the survivors to eschew all other wisdom that they might have gained from the essence of the books they had found. They did not want to read any more about how the establishment had destroyed itself. Volcanic eruptions were still happening everyday and they had to seek shelter or they would be eradicated as well. That era was over because of their errors. So much had changed since then. Only a few of the buildings erected in the past remained standing. Erosion made it impossible to grow plants, escalating temperatures made it even more difficult to breathe in the already scalding air and established bases of refuge were becoming harder and harder to find.
文明灭亡40年之后，他们在一次房地产拍卖会上发现了米西的文章。米西在文章中描述了社会如何发现全球变暖是个可疑的现象，他们都觉得可笑。这样发达的社会居然会得出如此错误的结论，这个观点使幸存者们避开了所有其他知识。从他们发现的那些书的精华中，他们是可以获得这些知识的。他们不再愿意阅读任何关于机构如何自我毁灭的文章。每天依然有火山喷发，他们不得不寻找躲避的地方，否则同样会被消灭。由于他们的错误，那个时代结束了。自那以后发生了很大的变化。过去建造的建筑物只有少量依然存在。由于有腐蚀，植物无法栽种。不断升高的气温使人在本已炽热的空气中更难呼吸，建好的避难基地也越来越难找到。
