10But不过
11since then, research shows temperatures exceeding that, leading to warnings of catastrophic自那时起,研究显示气温超过此值,导致出现灾难性警报。
12damage to Earth's life support systems.破坏地球的生命支撑系统
13In this episode, we'll be discussing how hot the planet could get using some useful在这个剧集中,我们将讨论 这个星球会有多热 用一些有用的
14new vocabulary.新词汇。

17But first, I have a question for you, Phil.但首先 我有个问题要问你 菲尔
18Scientists monitor climate change using the科学家利用
19Earth's energy imbalance, the difference between the solar energy entering the Earth's atmosphere地球能量的不平衡 太阳能量进入地球大气层的差别
20and the radiation going back out into space.辐射会回到太空
21But which unit do scientists use for this?但科学家用哪个单位来做这个?
22Is it A, Fahrenheit, B, watts per square metre, or C, joules?是A,华氏,B,瓦特每平方米,还是C,焦耳?
23Ooh, I know joules is something to do with energy, so I'm going to go with C.我知道焦耳和能量有关 所以我要和C一起去
24Well, we'll find out the answer at the end of the programme, although careful listeners好吧,我们会找出答案 在节目的结尾, 虽然仔细的听众
25might hear the answer sooner.可能早点听到答案
26Ooh!瓳
27Yes, exciting.是的,令人兴奋。
28So, how do scientists calculate the effects of climate change in the first place?那么,科学家们如何计算气候变化的影响呢?
29The answer is with models.答案是与模型。
30Huge amounts of physical and chemical data are fed into大量物理和化学数据被输入
31supercomputers, which then paint pictures of possible futures on Earth.超级计算机,然后画出地球上可能的未来的图片.
32But as NASA climate但作为NASA的气候
33scientist Kate Marvell explained to BBC World Service programme The Climate Question,科学家凯特·马维尔(英语:Kate Marvel)向英国广播公司世界服务节目"气候问题"(The Climate Question)解释,
34nothing is certain.没什么是肯定的。
35Climate models don't make predictions, they make projections.气候模型不做预测,它们做预测.
36Predictions are saying this is what预言是这样说的
37will happen.将会发生。
38And a projection is conditional.而投影是有条件的。
39A projection is if we do this, then this will happen.一个预测是,如果我们这样做, 那么这将发生。
40Climate models don't make predictions, those are statements about what's likely to happen.气候模型不会作出预测, 这些都是关于会发生什么的声明。
41Instead, they make projections about different possible futures, and these depend on many things.相反,他们预测了不同的可能的未来,而这些取决于许多事情。
42In other words, climate models are conditional, meaning that they depend on other factors.换句话说,气候模型是有条件的,这意味着它们依赖于其他因素.
43The main factor in climate change, of course, is human activity, especially greenhouse gas气候变化的主要因素当然是人类活动,特别是温室气体。
44emissions.排放量。
45Another influence on climate models is clouds.对气候模型的另一个影响是云.
46We usually associate hot summers with cloudless我们通常把炎热的夏天和无云地联系起来
47blue skies.蓝天
48But in fact, clouds play a big part in the climate, as Kate Marvell explained但事实上 云在气候中扮演了重要角色 正如凯特·马维尔所解释的
49to the BBC World Service.致英国广播公司世界服务社
50So the thing about clouds is that they have this dual effect.因此,关于云,它们具有这种双重效果。
51They both cool the planet by他们都冷却地球
52blocking sunlight, and they warm the planet because they have their own greenhouse effect.挡住阳光,它们让地球暖和 因为它们有自己的温室效应。
53Right now, the unit that scientists use to measure the energy imbalance of the planet,现在,科学家用来测量地球能量不平衡的单位,
54how much it's out of whack, is watts, like in a light bulb, per square metre.每平方米的电瓦就像灯泡一样
55Kate starts by saying the thing about clouds is she uses the expression the thing about凯特首先说 关于云的事是 她用表达
56to introduce the most important detail about something.介绍最重要的细节
57Here, that detail is that clouds both cool the planet by blocking sunlight, but also在这里,这个细节是,云层 既冷却地球 通过阻挡阳光,
58warm it by trapping heat.通过捕捉热量来温暖它。
59So climate models monitor clouds to accurately measure how much the Earth is out of whack.因此,气候模型监测云层 准确测量地球的消耗量。
60If something is out of whack, it's out of balance and not working properly.如果某件事出了问题, 它的平衡和不工作正常。
61Climate models sound very complicated to me, Pippa.气候模型听起来很复杂,皮帕
62For one thing, how can you monitor clouds首先,你怎么能监视云
63which are constantly moving and changing?哪些在不断移动和变化?
64Yeah, and how much information from around the world would the supercomputers need to超级计算机需要多少信息?
65make accurate projections?准确预测?
66It's a concern that BBC presenter Greia Jackson raised with英国广播公司主持人Greia Jackson 提出的关注
67凯特·马维尔为BBC世界服务节目The Climate Question.
68Surely we need to know the trajectory we're heading in, in order to adapt.我们当然需要知道我们前进的轨迹 为了适应
69Oh, absolutely.当然
70You know, I am very pro-science.你知道,我非常赞成科学。
71I am very pro-doing science because no climate我非常支持科学 因为没有气候
72change is unfortunately not on the table.不幸的是,改革没有摆在桌面上。
73Kate is very pro-science.凯特非常支持科学
74If you're pro-something, it means you're in favour of it.如是拥护者即是拥护.
75Models are模型为
76complex, but they're necessary because unfortunately no climate change at all is not on the table.复杂,但它们是必要的, 因为不幸的是,没有任何气候变化 没有摆在桌面上。
77And that's an idiom meaning it's not an option.这是一个典型的,意思是它不是一个选择。
78If all this sounds a bit depressing, Kate's final message is more hopeful.如果这一切听起来有点压抑,凯特的最后信息更充满希望.
79Climate models气候模型
80prove beyond doubt that the problem of global warming is created by humans,无疑地证明全球变暖问题是人类造成的,
81so we know beyond doubt that the solution is also in our hands.因此,我们毫无疑问地知道,解决办法也掌握在我们手中。
82Now Pippa, careful listeners might already know, but go ahead and reveal the correct现在,皮帕,小心听者可能已经知道了, 但继续,揭示正确的
83answer to your question.回答你的问题。
84Yes, I asked you which unit do scientists use to measure the Earth's energy imbalance,是的,我问你 哪个单位的科学家使用 测量地球的能量不平衡,
85and the answer was watts per square metre, and I didn't know that, Phil.答案是瓦特每平方米, 我不知道,菲尔。
86Right, it's time to recap the vocabulary we heard during this programme.对,是时候重述一下我们在节目中听到的词汇了。
87A prediction is a statement about what you think will happen in the future.一个预言就是关于你认为将来会发生什么的声明.
88The adjective conditional means depending on other factors.形容词有条件是指取决于其他因素.
89You can use the informal expression the thing about to introduce the most important feature你可以用非正式的表达方式 来介绍最重要的特征
90or detail of something.或细节的东西。
91The phrase out of whack means out of balance and not working properly.句子出格意味着平衡失常,工作不当。
92If you're pro-something, you're in favour of it.如是拥护者.
93And if something is not on the table, it's not an option, it's not available to us.如果有东西不在桌子上, 它不是一个选择, 它不能给我们。
