We're talking about the entire western part of India being a centre of volcanic activity with volcanoes
我們是指整個(gè)印度西部都變成了火山活動(dòng)中心，
and lava coming out, over a large area, over thousands of kilometres.
火山噴出的熔巖覆蓋了大片地區(qū)，達(dá)到數(shù)千公里。
Volcanic greenhouse gases contributed to an apparently massive global warming.
火山的溫室氣體使得全球大部分地區(qū)明顯變暖。
Some data point to an average rise in temperature of eight degrees centigrade in the last half million years before the impact.
在大碰撞發(fā)生之前的最后50萬(wàn)年，全球平均溫度上升了8℃。
This would have been devastating.
這是極具破壞性的。
We're talking about catastrophic effects in terms of changes in habitat,
我們是指災(zāi)難的負(fù)面影響，包括生活環(huán)境的改變、
changes in rain fall patterns, changes in climate, all of these you can think of,
降雨方式的改變、氣候的改變，這些你能想到的，
all of the things that are going on in the modern world magnified many many times, many many orders of magnitude indeed.
所有這些在現(xiàn)代世界仍舊繼續(xù)著，只是被放大了許多倍，數(shù)量也增加了許多倍。
It is not clear what effect the Deccan Traps had on the dinosaurs.
我們并不清楚德干巖群火山活動(dòng)對(duì)恐龍?jiān)斐闪撕畏N影響。
The fossil record for this crucial period is difficult to interpret.
這一嚴(yán)酷時(shí)期的化石記錄很難說(shuō)明問(wèn)題。
But the fossil record for other animals, such as the ammonites, is far better
但是其它一些動(dòng)物的化石記錄，例如菊石，則要完備得多，
and using this some argue it's possible to infer what was happening to the dinosaurs.
于是有人認(rèn)為靠它可以來(lái)推斷恐龍身上發(fā)生的事。
