treating COVID-19 patients, switching to the more advanced N95 respirators
if they’re carrying out procedures that might create aerosols. But such

变暖教只敢说比100多年前提高了1度多，但是不敢和罗马帝国时期相比。罗马时代英国
可以种葡萄，最近才刚刚温暖到可以考虑种葡萄。
另外就是红线蓝线之争，按暖教预测，100年升温得是2，3度。然而只有1度，是因为自
然本来是个变冷的过程，对冲了人为的变暖。
然而，火星的温度也提高了........
其实如果不是大冰河小冰河冻死了山顶洞人，尼人，压根也就没有非洲走出来的现代人
什么事儿了。
从地质年代来看，地球这几十亿年来一直在变冷，这也符合行星的生命周期。
而且，真正可能灭绝人类或者fallout末世景象的可能scenarios里，小行星，黄石，核
冬天。无一例外都是aerosol遮蔽阳光造成的暂时性永冬导致生物大灭绝。
而暖化? 即使变暖教预测的全部成真，也不过是癣芥之疾。连一次二战的破坏都赶不上
。最多就是灭绝个把北极熊，我看都玄。 |

一个2qt的是100刀，需要稀释1倍使用，所以实际上你得到的是2qt/4qt for 50/100刀
。用罐装漆比较麻烦，需要稀释+过滤，还要用喷枪，而且用的喷枪好坏直接影响用多
