你牛角钻鹿角力去了,看看这个,到底火山喷了变暖还是变冷~~ The least likely but worst-case volcanic eruption at Yellowstone would be another explosive caldera- forming eruption such as those that occurred 2.1 million, 1.3 million, and 640,000 years ago. Such an eruption would produce ash columns that exceed 10 km (6 mi) and cover much of the United States with some ash. Once entering the stratosphere (higher than about 10 km or 6 mi), the ash particles would circle the globe and, in combination with the sulfur dioxide emitted during an eruption, could cause global temperatures to drop. |

还是那黄石来打比方,因为离我们比较近,根据计算机模拟演示,ysp的超级火山一旦爆发:美国2/3的国土就无法使人类生存了~~ 火山爆发周围1000平方公里内90%的人都将挂掉~~ 在三到四天内大量的火山灰抵达欧洲大陆,持续飘荡在天空的火山灰将会使地球的年平均气温下降10℃,地球北极则会下降12℃,这样的寒冷气候至少会持续6至10年~~ 本着教书育人的原则,还是给你上了这课~~ |
