Back then, it seemed the drought that helped cause this catastrophic event was simply due to climate variability.

当时，造成这一灾难性事件的干旱似乎仅仅是由于气候变化造成的。

" Every event is a combination of climate change and climate variability, " says Caroline Wainwright, a climate scientist at Imperial College London.

“每个事件都是气候变化和气候变率的结合，”伦敦帝国理工学院气候科学家，Caroline Wainwright 说。

In conclusion, while natural events do contribute to climate variability, the weight of evidence strongly suggests that recent climate change is largely anthropogenic.

总之，虽然自然事件确实会导致气候多变性，但大量证据强烈表明，最近的气候变化在很大程度上是人为的。

" Is this within the range of climate variability or signal of accelerated warming? My concern is it might be too late if we just wait to see, " she tweeted.

“这是正常范围内的气候变化还是全球变暖加速的信号？我担心如果我们只是观望而不采取行动，到时候恐怕就来不及了。”

So, just set up, you know, what was the purpose of what you were doing—to try to understand the climate variability of this area—and what you did, and what your approach was.

你研究的目的是什么——试着了解这一地区的气候变化——还有你做了什么，以及你的方法是什么。
