气候担忧与优先级的错位
Jeyan Jeganathan: 今年夏天给全球各地带来了极端天气。尼泊尔爆发山洪,欧洲遭遇致命热浪,而在加拿大,野火摧毁了安大略省北部社区,导致数千公里外的空气质量骤降。专家也警告称,气候变化将使天气事件变得更加频繁和极端。
如今加拿大人确实对气候变化感到担忧。最近的一份报告发现,绝大多数人都对此表示关切。但当你询问加拿大人哪些问题对他们最重要时,气候变化却落后于生活成本、唐纳德·特朗普等议题。
那么,如果加拿大人担心气候变化,为什么它没有成为更高的优先事项?要怎样才能营造出紧迫感?未来几个月还将面临更多考验,专家表示一场历史性的**厄尔尼诺现象(El Niño)**正在酝酿,这可能对即将到来的冬季产生重大影响。我是 Jeyan Jeganathan,这里是《The Rundown》。
Amber Bennett、Natalie Thomas、Naila Moloo,非常感谢三位加入《The Rundown》参与这场重要的对话。Amber,你的机构 Reclimate 今年发布了一份报告,显示加拿大人虽然依然关心气候变化,但它已经不再是首要任务。请帮我们理解这些调查结果背后的原因。
英文原文
Jeyan Jeganathan: This summer brought extreme weather around the world. Flash floods in Nepal, a deadly heat wave in Europe and here in Canada, wildfires devastated northern Ontario communities and sent air quality plummeting thousands of kilometres away. Experts also warn that climate change will make weather events more frequent and extreme.
Now Canadians are worried about climate change. A recent report found that an overwhelming majority are concerned about it. But when you ask Canadians what issues matter most to them, climate change falls behind things like cost of living, Donald Trump and more.
So if Canadians are worried about climate change, why isn't it a bigger priority? And what would it take to create a sense of urgency? And there's more in store in the coming months. Experts say a historic El Nino is building, and it could have a big impact on the winter ahead. I'm Jeyan Jeganathan. This is The Rundown.
Amber Bennett, Natalie Thomas, Naila Moloo, thank you so much for joining us on The Rundown for this important conversation. Amber, your Organization Reclimate put together a report this year that showed that Canadians are still concerned about climate change, but it's no longer the priority. So help me understand what's behind the findings.
Amber Bennett: 好的,谢谢。我们看到的情况是,气候变化作为公众心目中的头号议题大约在2018年达到顶峰。随后,随着生活成本、通货膨胀、住房问题,以及近期围绕特朗普对经济和主权威胁带来的困扰,气候变化的关注度逐渐下滑。
我想在此指出的是,人们完全有可能对某件事感到担忧——事实上,加拿大人对气候变化的关注一直很稳定。每当发生野火或极端天气等事件时,这种关注度就会达到峰值。始终有70%到80%(即十个人中有七八个)的加拿大人表示他们担心气候变化,这一基本盘保持得很一致。
但与此同时,这对他们来说并不一定是最紧迫的问题。我认为明确这一点非常重要:一方面某人可以对某事高度关切,但另一方面这并不是当下最急迫的事。对许多加拿大人来说,生活成本、通货膨胀等问题在眼下让人感觉更加迫在眉睫。
英文原文
Amber Bennett: Yeah. Thank you. So what we see is that climate change kind of peaked as a top issue for people in, say, 2018. And then, you know, has slowly slipped off as cost of living, inflation, housing, and more recently, the, the troubles that we've been experiencing around Trump with the economy and threats to the, to sovereignty.
So what I want to point out here is that it is possible for people to be concerned about something. And in fact, Canadians have consistently been concerned about climate change. And when we have, you know, events like wildfires or extreme weather, we we see that kind of peaking. So there's been a base of, you know, 7 to 8 out of ten Canadians are report that they've been concerned about climate change. That's remained consistent.
But at the same time, it's not necessarily the most pressing issue for them. So so I think that that's really important to to note that on the one hand, somebody can be highly concerned about something, but it's not the most pressing issue for them. And in fact, for many Canadians, you know, issues around cost of living, inflation, etc. are more feel more pressing at the moment.
生存危机叠加与生态焦虑转移
Jeyan Jeganathan: Naila,你从14岁起就走上了可持续发展的道路,现在20多岁,就读于北卡罗来纳大学(University of North Carolina)。在你的同龄群体中,对气候变化的紧迫感发生了怎样的变化?我知道你不能代表所有人,但我很好奇,你们现在的交流讨论都是什么样的?
英文原文
Jeyan Jeganathan: Naila, you have been on the sustainability track since you were 14. You're now in your 20s. You study at the University of North Carolina. How has the urgency about about climate change sort of changed in your cohort? I know you don't speak for everybody, but I'm curious, what are those conversations like?
Naila Moloo: 是的,我觉得相比气候变化,我现在参与讨论更多的是像**人工智能(AI)**这样的话题,这确实有点令人担忧。我感觉当下让年轻人感到焦虑的议题太多了,导致气候变化在优先级列表上逐渐下滑。
几年前,气候变化还是绝对的热门话题,我经常参与相关讨论,大家当时普遍有着强烈的生态焦虑(eco-anxiety)。我倒不觉得生态焦虑已经彻底消退了,只是当下影响人类的其他各类议题带来了新的焦虑。这是我观察到的一个有趣现象。
英文原文
Naila Moloo: Yeah, I think I have a lot more conversations about topics like AI now, as opposed to climate change, which is a little bit concerning. I just feel like there are so many issues that youth are anxious about, that climate change is kind of going down on the priority list.
So a few years ago, I feel like this was the hot topic and I was constantly having conversations about it, and people had a lot of eco anxiety. I don't think that eco anxiety has necessarily fizzled out. I just think there's anxiety about a lot of other topics that are impacting humanity today. So that's something interesting that I found.
Jeyan Jeganathan: Natalie,最近联合国报告称,在地球变暖问题上我们已经过了不可逆转的临界点。火上浇油的是,上周一位人工智能吹哨人警告称,科技消灭人类的速度可能比我们预期的还要快。作为心理治疗师,当你听到这些时,你如何看待人们的应对与承受能力?
英文原文
Jeyan Jeganathan: Natalie. Recently, the UN reported that we are past the point of no return on the warming of the planet. To add fuel to the fire, then last week, an AI whistleblower warned that technology is going to wipe out humanity sooner than we'd expect. Please help me here. As a psychotherapist, you know, when you hear that, what do you think about people's ability to cope?
Natalie Thomas: 这是一个非常好的问题。在心理层面,这对大众来说确实难以承受,令人不知所措。我认为气候变化和人工智能的本质都是存在性危机(existential issues),因为它们对我们作为一个物种的存在提出了极其深刻的拷问。
人们的应对方式各不相同。作为一名关注气候议题的治疗师,我的诊所会吸引一些本身就对自然关切、怀有生态焦虑和气候焦虑的人。但总的来说,我发现人们要么选择心理封闭——这是一种普遍倾向,觉得这一切实在太沉重了,干脆转过头去不看。大家会想:“我不想去关注气候,也不想去关注人工智能,因为这实在承受不来。”
而那些积极参与应对的人同样感到不堪重负。我接触过一些环保行动主义者,他们饱受**身心耗竭(burnout)**之苦,因为他们试图抗击所有问题,试图拯救人类和自然的一切,最终走向职业倦怠。所以心理应对是一件非常微妙的事。我经常与来访者探讨:我们能否去体会一部分感受,但同时在生活中寻找其他能带来更多平衡的支点?
然而这确实令人难以招架。这也解释了为什么对许多人来说,气候议题正逐渐淡出核心视线,因为人类往往更关注最直接体验到的事物。比如当我收到一条关于AI可能毁灭人类的警报时,突然间我那一周所有咨询里大家都在谈论AI。又比如像生活成本这种与我们切身相关、近在眼前的体验——当我去超市买菜付账时,那是实实在在感受到的痛点。而气候变化往往是一个缓慢演进的过程,因此通常很难让人持续感受到那种紧迫感。
英文原文
Natalie Thomas: Yeah, that's a really good question. It's a lot for people psychologically to handle, right? It's it's overwhelming. And I think the nature of climate change and of AI, they're both such like existential issues because they raise these really profound questions about our existence as a species.
So people cope in various ways. I, I work with some people, you know, I'm a climate aware therapist who so it that draws some people into my practice that already have this concern for nature and eco anxiety and climate anxiety. But overall, I think people are finding either they they shut down. It's a it's a, you know, common tendency to just say it's just all too much. So they just turn away, right? It's like, I don't want to look at climate. I don't want to look at AI because frankly, it's just too much.
The people that engage feel overwhelmed as well. So they might suffer. You know, I work with some activists. They suffer from burnout because they're trying to, to fight all the things and fight for, you know, humans and nature and, and all of those things. And then they can also lead to burnout, right? So, so coping is a tricky thing. It's, you know, I often talk to people about, can we feel into it a little bit, but also find other aspects of our lives where we can maybe find more balance, but it is overwhelming and it makes sense, I think, even of the idea that for a lot of people, climate is drifting because we tend to be more concerned about what is most immediately experienced, right?
So so if I get this, you know, alert about AI and we're all going to die from AI, suddenly I found that we can in my sessions, that's all everybody was talking about. And so I think what we're experiencing firsthand and more, what is more present for us, like cost of living. When I go to pay for groceries or, you know, that's what I'm noticing. But often things like climate change are a bit of a slow creep. So it's harder to feel the urgency. I think.
动机性推理与能源转型的双重心理
Jeyan Jeganathan: Amber,我想聊聊这个新的优先级清单。在我们演播室里,我们讨论过国家建设项目,也讨论过输油管道(pipelines)。然而,加拿大人又希望成为可再生能源超级大国(renewable energy superpowers),这里存在一种微妙的平衡。但根据你们的报告,我们既想要管道,又想弄清楚在现任政府领导下如何处理与南部邻国的关系。这在逻辑上该如何理解?
英文原文
Jeyan Jeganathan: Well, Amber, I want to talk a little bit about sort of that the new priority list, let's call it here in our studios. We've had conversations about, you know, nation building projects. We've talked about pipelines, Canadians, though, want to be renewable energy superpowers. Like there's an interesting balance here. But according to your report, we also want pipelines. We want to want to figure out how to deal with our neighbours to the south, with the current administration. How does this make sense?
Amber Bennett: 是的。当我们向加拿大人提问时——我们去年做了一项研究,问他们:“你更希望加拿大成为可再生能源超级大国,还是石油和天然气超级大国?”绝大多数人,即 70% 的加拿大人(十分之七)表示,他们更倾向于、或者会为加拿大成为可再生能源超级大国感到更自豪。我认为这种倾向横跨加拿大的所有地区,即便是在我所居住的阿尔伯塔省(Alberta)等地区,这一结论依然成立。
所以一方面我们想成为可再生能源大国;但另一方面,我们也认为自己可以两者兼顾。加拿大人持有这样一种信念:我们既可以扩建化石燃料基础设施、修建输油管道,同时又能成为优秀的气候行动者并实现气候减排目标。
部分原因在于,普通人并不容易完全理解实现减排目标、碳排放指标背后的所有复杂构成,这在一定程度上属于气候认知素养的问题。但另一方面,正如 Natalie 所提到的,这在某种程度上是一种动机性推理(motivated reasoning)。我们听到政治领导人谈论建设管道的必要性,当你个人对此无能为力时,相信“我们可以两者兼得”是非常诱人且轻松的选择。这样我们既能在气候上有所作为、做良好的全球公民并互相照顾,同时又能大建管道、提振经济。
Natalie 也许可以从心理学角度进一步阐述,但加拿大人确实处于一种两难境地:一方面我们需要保障国家经济安全,另一方面我们日复一日目睹极端天气、森林大火和城镇被烧毁的报道。两者很难兼得,因此我们看到许多动机性推理的迹象。
英文原文
Amber Bennett: Yeah. When we ask Canadians, we did some research last year and we asked them, would you rather be a renewable energy superpower or would you rather be an oil and gas superpower? And overwhelmingly, 70% of Canadians. So that's 7 in 10 Canadians said that they would prefer to be or rather, to be or feel more pride in Canada being a renewable, super power. And I think that this holds across all regions of Canada. So even if you're in in areas or regions like where where I live in Alberta, it still holds true.
So I think on the one hand, we want to be a renewable energy superpower. On the other hand, we also think that we can do both. So Canadians also hold the belief that we can build out fossil fuel infrastructure, build out pipelines while still being good climate actors while still meeting our climate targets, etc. And part of that has to do with it's not really easy to understand necessarily all of the complicated components that go into. What does it mean to meet targets? What do emissions mean, etc. and so there is, to some degree a literacy component of that.
But on the other hand, I think, as Natalie was mentioning, there's also a, to some degree motivated reasoning on, you know, we feel that and we see our political leaders talking about the need to build out pipelines. And if you don't really have a lot that you can do about it, it's, it's tempting. And it's easy to believe that we can do both. So we can act on the climate, be good global citizens, take care of each other. And on the other hand, we can also build out pipelines and, and, you know, address our economy and, and, etc.
So, you know, I think that maybe Natalie could talk more about this, but to some degree, Canadians are in a bind, right? There's really they're in a bind in which we, on the one hand, need to secure our economy. We need to secure our country. And on the other hand, we are sitting in day after day, you know, stories of the kinds of impacts and extreme weather and forest fires and towns burning down. And so it's hard to do both. And so I think, you know, maybe we can talk a little bit about, you know, some of the motivated reasoning and some of the indicators we see.
直观体验与归因断层
Jeyan Jeganathan: 我想了解一下大家亲眼目睹的天气事件类型。在这张图表中,我们向加拿大人提出了一个问题:与五年前相比,这些事件是增多了、减少了还是保持不变?
排在首位的是野火(74%);其次是烟雾或雾霾等较差空气质量(68%);紧接着是极端高温(66%)、干旱(48%),最后是洪水(41%)。Amber,你能否简要帮我们分析一下,能从这些结果中得出什么结论?正如 Natalie 提到的直观感受,当看到野火高居榜首时,很多人都会回忆起刚刚过去的夏天,安省西北部民众撤离的画面依然历历在目。我们能从这些数据中学到什么?
英文原文
Jeyan Jeganathan: Well, I want to get a sense of the types of weather events folks are seeing and witnessing. In this graph. We're showing the question that was put to Canadians is, are there more, fewer or the same amount of these events compared to five years ago? Top of the list is wildfires at 74%. Then poor air quality like smoke or smog at 68%, followed by extreme heat at 66%, droughts at 48%, and finally floods at 41%.
Amber, very quickly, can you help us understand what what can we learn from these results? You know, Natalie had mentioned sort of the what we're sort of seeing in front of us. And so when I see wildfires up on that list, that is something that a lot of people can remember this past summer. You know, northwestern Ontario, people fleeing those images are quite vivid here. But what can we learn from these results?
Amber Bennett: 是的。我认为最直观的结论是,加拿大人是通过日常生活中亲眼所见、亲身经历的影响来理解气候变化的。因此毫不奇怪,那些与高温最直接相关、在加拿大表现得最剧烈的事件最容易引起公众警觉。
但我想指出的是,另一方面,我们也看到极端天气对气候变化以及人类活动人为成因的**归因关联度(attribution)**正在下降。换句话说,人们一方面将极端天气事件与气候变化联系起来,但另一方面又可能认为这属于自然波动,或者是森林防火管理不善等原因。这就容易产生认知上的混淆。我们仍需做大量扎实的工作,把极端天气明确归因于气候变化,并进而指明其根源在于化石燃料的燃烧。
英文原文
Amber Bennett: Yeah. So I think that top line is Canadians are making sense of climate change through the impacts that they're seeing and that they're living and experiencing day to day. So so, you know, not surprisingly, those things that we most associate with heat and the things that we see most dramatically in Canada are, are breaking through.
What I would point out is that, on the other hand, what we also see are declining association or attribution to to climate change. And, and those being human caused. So on the one hand, you can at the same time, you know, connect extreme weather, extreme weather events to climate change, but you can also believe that it may not be, you know, it may be natural or, or there may be, you know, forest fire, mismanagement, etc. So, so it tends to get a little bit jumbled up. And, and I think that there's some real work that we can do to clearly connect extreme weather to, to climate change. And then the cause of that is burning fossil fuels.
Jeyan Jeganathan: Natalie,请你也谈谈。这份清单列出的简直就是噩梦的具象化——干旱、野火、洪水。这如何在一些人心中引发焦虑,甚至导致冷漠?
英文原文
Jeyan Jeganathan: Well, Natalie, let's get you in there. You know, this list, you look at it, we're talking about, you know, what nightmares are made of, right? Droughts, wildfires, floods. How does this cause anxiety or even apathy for some people?
Natalie Thomas: 这确实非常耐人寻味。人们往往哪怕只是闻到烟味就会被触动。例如当安大略省南部烟雾弥漫时,人们的焦虑感急剧飙升,因为“天哪,我能闻到烟味”。一旦能切身闻到,就会产生一种充满焦虑的生理本能反应(visceral response)。
一方面这些感受会被激发到顶点;但另一方面,正如 Amber 所言,我们也会产生一种无力感:“我能怎么办?我到底能做些什么?”面对无法承受的前景——万一火势加剧、持续蔓延并逼近我怎么办?大脑会不受控制地设想各种糟糕场景,但转念一想自己又根本无能为力。这种心理往往会导向一定程度的漠然(apathy)。
因此,人们更容易将注意力转移到眼前能够掌控的事情上,比如“我在家里买个更好的空气净化器”,因为掌控净化器比解决气候变化引发的森林大火要容易得多。人们感到无能为力,因而更倾向于关注诸如“在自己家里能做点什么”这类眼前微观的事情。
英文原文
Natalie Thomas: Yeah, it's it's really interesting. You think I always think that, you know, people are activated by the even by the smell of smoke, right? So when we were experiencing more, more smoke here in southern Ontario, for example, people's anxiety really spiked, right? Because it's like, oh my gosh, I can smell it. And if I can smell it, it causes this really kind of visceral response and reaction to it that's filled with anxiety.
So on the one hand, those things peak. But on the other hand, we also feel a sense of, I think, as Amber mentioned, like a, like a helplessness, like what do I do? Like, what can I possibly do? And so that can also lead to a certain amount of apathy as well, because it's in the face of overwhelming, like, what if these fires get worse and continue and get closer to me? My mind goes on and on and thinks of all these scenarios, but at the same time, what can I possibly do about this?
So it's easier to focus a little more on like the, again, the immediate like, oh, I'll get a better, you know, air purifier in the house because it's easier for me to have control over that than it is for me to do something about climate change causing forest fires. Right. There's a degree to which people feel helpless to do that. So they tend to focus more on the immediate what can I do? For example, in my house? Right.
青年一代的行动力与跨界叙事
Jeyan Jeganathan: 让我们谈谈行动与不作为。Naila,许多加拿大人目睹了气候变化的渐进过程,但不幸的是,你们这一代人生来就置身其中。这如何塑造了你们决定采取行动或不作为的心态?
英文原文
Jeyan Jeganathan: Well, let's talk about action or inaction. Naila. A lot of Canadians have seen the gradual results of climate change, but your generation, unfortunately, was born into this. So help me understand how does that shape what you guys decide to do or not do?
Naila Moloo: 对我个人而言,气候变化是我从小就在探讨的议题,而且长期以来一直是年轻人讨论的核心。在我接触的人群中,这很大程度上转化为了实际行动,这非常鼓舞人心。因为大家一直在谈论气候变化,内心深处有一种走出去做实事的渴望。
而且我发现社会各界非常乐意帮助年轻人,这一点至关重要。让年轻人参与进来极其重要。我记得14岁时联系实验室教授,询问能否去他们的实验室研发自己的太阳能电池(solar cells),他们欣然答应了。这对我的人生轨迹产生了巨大影响,让我觉得自己在做些什么来缓解生态焦虑,在为自己真正关心的难题构建解决方案。
我认为我们年轻一代普遍拥有一种积极进取的实干态度。我们需要通过为年轻人提供更多机会来保持这种势头,让他们能够去探索机遇,并为现实难题构建切实的解决之道。
英文原文
Naila Moloo: Yeah. Well, I think for me personally, as you said, climate change has been an issue that I've been talking about since I was really little. And I feel like it's been a discussion among youth for a really long time. I feel like it translates a lot into action with the people that I talk to, which is inspiring because, you know, you're constantly talking about climate change. So there's this desire to go out and do something about it.
And I found that people are really willing to help youth, and that is super important. I think it's really important to get youth involved. I remember when I was 14, I was reaching out to professors of labs and being like, can I come develop my own solar cells at your lab? And they said, yes. And that really impacted my journey a lot because it made me feel like I was doing something to help me cope with my eco anxiety. And I was helping build something, a solution to a problem that I really cared about.
So I think there is this general like, go getter attitude for my generation and for young people. And I think we need to keep that up by giving opportunities to young people so that they can go and pursue different opportunities and, and build real solutions to problems.
Jeyan Jeganathan: 我很好奇,Naila,很多听众可能会觉得作为个体去做出重大改变承受了巨大的压力。当我们在宏观上谈论国家建设项目、输油管道和化石燃料时,个体该如何与这些庞然大物抗衡?
英文原文
Jeyan Jeganathan: I am curious, Naila, you know, there might be a lot of people who are listening to this who might feel like there is a lot of pressure as an individual making big changes. When we are talking about nation building projects, we're talking about pipelines, we're talking about fossil fuels. How do how do individuals compete with that?
Naila Moloo: 气候变化与一切事物都有交集,理解这一点非常重要。无论你对什么领域感兴趣,大概率都能找到将可持续发展融入其中的切入点。
我主修工程学,因此我自然偏向于构建具体的实体技术解决方案,这是参与其中的绝佳途径。但它绝不局限于技术项目。如果你对艺术感兴趣,艺术与气候变化之间存在极佳的交汇点,因为艺术能够抓住眼球、唤起人们的关切。有时大家不想阅读50大段文字,他们只想看一张震撼的照片并产生情感共鸣,这同样能产生巨大的推动力并催生变革。
摄影、艺术、叙事、写作皆是如此。我自己对写作也很感兴趣,目前正在创作一套关于新兴技术的儿童绘本丛书,其中部分内容与气候密切相关,例如可控核聚变能源(fusion energy)。这样做的目的就是让孩子们从小对这些技术产生兴趣,并在早期就建立对这些全球性挑战的认知。
英文原文
Naila Moloo: Well, I think climate change intersects with everything. And that's what's really important to understand. Anything that you are interested in, you can probably find a way to tie sustainability into that.
So I am studying engineering. So obviously I'm a little bit biased with like building these like hands on solutions. And I think that is a really great way for people to get involved. But also it does not have to be a technical project. You might be really interested in art. And, you know, there's also this beautiful intersection of art and climate change because art captures people's attention and it gets people to care. And that is important. Sometimes people don't want to go read 50 blocks of text. They just want to look at a photograph and feel something. And that can be extremely powerful and lead to change as well.
So photography, art, storytelling, writing. I'm actually really interested in writing too. And I see this intersection of writing and climate change, because obviously you can write about what you feel. And I'm working on a children's book series right now about emerging technologies, and some of them relate very heavily to climate, like fusion energy. And that has the intent of getting people interested in these technologies from a really young age and understanding these problems from a young age.
破除极化:寻找共识与平衡叙事
Jeyan Jeganathan: Natalie,我们该如何更好地跨越所有人群去传播气候变化议题?目前显然存在认知断层,我们需要怎样的传播策略?应该聚焦讨论些什么?
英文原文
Jeyan Jeganathan: Natalie, how do we better communicate climate change to to all demographics, really, but there is a gap here. And so what is the communication skills here? What do we need to be talking about?
Natalie Thomas: 我们生活在一个极易走向两极分化的时代,尤其在社交媒体上,人们往往倾向于争吵而非理性讨论。
我经常思考两点:第一,认识到即使看似对立的观点之间,也往往存在共同的契合点。例如大家都能达成共识的是,没有人希望经历森林大火或洪水,没有人愿意承受这些痛苦。我们在成因解释、政治立场上的分歧才会引发冲突。如果我们能找到共同点并保持开放心态,这将是一个很好的切入点——我们都认同这些灾害令人担忧,并且我们正在经历相同的痛苦,即便我们在致灾原因或解决方案上持有不同信念。诉诸人类共通的情感体验,是打开沟通大门、进而传递更多信息的有效方式。
第二,我常常想到气候学家 Katharine Hayhoe。我非常喜欢她的传播方式:她在社交媒体发帖时总是以这样的结构开头:“这里有一个好消息,这里有一个不太好的消息,这是我们能够采取的行动。”这种方式非常棒,它呼应了人们对希望的渴求,让人觉得事情并非全盘崩溃,从而不会立刻陷入“天啊,又来了一件可怕的灾难,我根本不想听”的封闭状态。
通过传递希望、结合艺术等美好事物,采取这种平衡的传播方式,我们就不会让公众陷入绝望、无助、冷漠或崩溃的自动应激反应中,而是能够基于共同的感受与体验相互联结。
英文原文
Natalie Thomas: Yeah, I think it's we can you know, clearly we live in a time where we can polarise very quickly on, on things and we're more apt to, especially on social media, to, to fight rather than discuss.
And I think one thing that I often think about, there's a couple of things, I guess one is recognising that what seemed to be opposing views, there's often something that's that we do agree on. And so I think we can all agree, for example, that none of us want to experience what it's like to live through a forest fire or a flood, or to suffer in these ways. Our differences in terms of interpreting what causes them and all of our political views and things like that, are the ones that start to clash, right? So if we can find a point of commonality and be open to that, I think it helps. And it's a way in to say, well, you know, we both agree that these things are really concerning and that we're experiencing something that is the same, even if we have different beliefs about what's causing it or what the solution is. And so I think appealing to the common human experience, the emotional experience can be a way in to communicating, right, to actually bringing in more information.
And I'm mindful too, I keep thinking of if you're familiar with Katharine Hayhoe, but I love the way she communicates climate information because she'll always start in her social media posts with like, here's the good news, here's the not so great news, and here's what we can do. And I'm like, oh, that's great, right? So it appeals to people's sense of like, there is something good that's happening. It's not all terrible. So you don't shut down immediately in the oh, great. Here's another terrible thing that's happening. And it's just, I don't want to know about it, but more like, here's a good thing.
And so I think that way also of, of trying to appeal to people's hope and that, you know, that we want to enjoy things in our life, like art, right? Like this discussion about art or that there are still beautiful things in the world. And I think there's, again, that kind of balanced approach. So we're not kind of like triggering people into an automatic response of hopelessness or helplessness or apathy or overwhelm or something like that. It's more like, can we relate to, you know, relate to each other in the ways that we're similar, right? And we're feeling the same things.

太平洋超级厄尔尼诺的科学机制
Jeyan Jeganathan: 太平洋目前正在酝酿一场非同寻常的厄尔尼诺现象,它被形容为前所未有。那么它将如何影响安大略省?气候变化在其中扮演了什么角色?
现在加入我们为我们解读科学原理的是**加州大学洛杉矶分校(UCLA)**气象学主管 Janine Banff。Janine 所在的洛杉矶距离我们讨论的升温海域并不远。欢迎你,Janine。让我们从基础讲起:究竟什么是厄尔尼诺现象?
英文原文
Jeyan Jeganathan: There is an El Nino currently brewing in the Pacific and it is a doozy. It is being referred to as unprecedented. So how could it affect us here in Ontario? And is climate change playing a role?
Joining us now to help break down the science is Janine Banff, director of meteorology at UCLA. Not too far from the warming waters in the Pacific that we are talking about. Janine. Great to have you. Let's start with the basics. What exactly is an El Nino?
Janine Banff: 嗨,Jeyan,很高兴来到这里。让我们直接深入了解什么是厄尔尼诺。首先,厄尔尼诺是赤道太平洋海域的海水变暖现象,是一种自然气候模式。它大约每2到7年发生一次,通常持续9到12个月左右。
但要真正理解厄尔尼诺,我们首先必须了解太平洋在正常年份的基准状态。在没有厄尔尼诺或拉尼娜的常规年份,太平洋上空盛行东风信风(Trade winds),风从东太平洋吹向西太平洋。当这种情况发生时,风力将所有温暖的表层海水推向西部(亚洲方向)。随着表层暖水向西移动,来自深海更冷、密度更大且富含营养物质的水体向上涌升,这就是所谓的涌升流(upwelling)。这会滋生丰富的浮游植物和养分,使渔业蓬勃发展。这是正常年份海洋与大气相互作用的标准状态。
但在厄尔尼诺事件中,这些东风信风会减弱、放缓甚至逆转。一旦发生逆转,西太平洋汇聚的全部温暖海水就会回流,向东涌向美洲沿岸(南美洲和北美洲西海岸)。这就是我们在厄尔尼诺期间观察到的海表温度变暖。因此并不是海水本身凭空变热,而是温暖海水的空间位移。当暖水回流东太平洋时,会强烈抑制深层冷水的涌升,深海富含营养的水体无法上升,表层完全被温暖海水覆盖。
英文原文
Janine Banff: Hi, Jeyan. It's a pleasure to be here. Thanks for having me. And yeah, let's start. Let's let's get right into what an El Nino is. You know, first of all, an El Nino is a warming of the equatorial Pacific Ocean. And it's this natural climate pattern. It occurs every around 2 to 7 years, and it can last from about nine months to about 12 months.
But in order to really understand what an El Nino is, we first have to understand the normal or the regular conditions of the Pacific Ocean. So normally what we see during like a a regular, a regular year without an El Nino or a La Nina, we have prevailing winds. These are easterly winds, winds blowing from the eastern Pacific towards the western Pacific. These are trade winds. And when that happens, it takes all the warm surface ocean waters. And it pushes it towards the west, towards Asia. And so when that happens, there's a displacement of warm water at the surface. So colder, denser nutrient waters from deeper below will rise towards the surface. And this is what we call upwelling. This is when we get nice phytoplankton and nutrients. And you know, the fishing industry is booming. So it's on a on a regular year, right? So this is a normal state of, of the, the, the ocean atmosphere sort of interaction.
But with an El Nino event, what happens is those easterly trade winds, they slow down, they weaken, they sometimes even reverse. So when that happens, all that warm water. Now from the Western Pacific sloshes back. It moves back towards the eastern Pacific, towards the Americas, off the coast of South America. North America. Right. And so that's the warming that we're seeing with the sea surface temperatures. It during an El Nino event. So it's not that the waters are actually getting warmer. It's just displacement of that warm water. And so when that warm water sloshes back towards the east, it really suppresses that upwelling. So we don't longer have that nutrient filled waters from the deeper ocean. It's now warm and it's now suppressed.
Jeyan Jeganathan: 正如你所说,这是一种每隔2到7年发生一次的自然气候模式。但这次的厄尔尼诺被称为“前所未有”、“超级强化”等等。这究竟意味着什么?它与其他历史上的厄尔尼诺有何不同?
英文原文
Jeyan Jeganathan: Help me understand here, as you mentioned, this is a natural climate pattern, as you talked about, you know, 2 to 7, 2 to 7 years. But this one is being considered has been called a number of things unprecedented, supercharged, all of that. What does that actually mean? Is this different than the other El Ninos.
Janine Banff: “超级厄尔尼诺”、“超级增压”——这些都是媒体上的热词。在气象预报和科学界,我们通常称之为强厄尔尼诺(very strong El Niño)。
要界定是否属于厄尔尼诺年,赤道太平洋区域的海温需要比该时期的历史平均值高出约 0.5 摄氏度。而在强厄尔尼诺事件中,温度正异常通常达到 2.0 摄氏度或更高。而在当前这次事件中,数值模型预测和实际观测显示,海温比平均水平高出了 3.0 摄氏度以上,这是极其罕见且惊人的。
英文原文
Janine Banff: Super El Nino supercharged? All these things that we're hearing in the media. Right. And so forecasters, scientists usually coined the phrase just a very strong El Nino.
So in order to even classify whether we're going to have an El Nino year or not, we have to see temperatures within the equatorial Pacific region to be about 0.5 degrees warmer than average for for that time of year. And for that particular period. With us, call it what you may, but with a really strong El Nino, that temperature anomaly is about two degrees or more greater, right? Like so where we're seeing temperatures above the the normals, about two degrees in this particular case, the models are showing. And now observations that we're seeing are over three degrees Celsius from the average. So that's on. Halton.
北美气候冲击与急流变轨
Jeyan Jeganathan: 看来我们得想些新的形容词了。你身在洛杉矶,而我们在安大略省。加拿大人在过去几个月经历了一系列野火和洪水等极端天气,这次前所未有的厄尔尼诺对加拿大和安大略省究竟意味着什么?
英文原文
Jeyan Jeganathan: All right. So we're going to have to think of some new adjectives here as well. Help me understand you're obviously you're in LA. We are here in Ontario. What does this mean? Canadians have seen some some pretty extreme weather over the last couple of months when we're talking about wildfires, when we talk about flooding, what does this actually mean for Canada and Ontario, specifically with this El Nino?
Janine Banff: 对于这次特殊的厄尔尼诺,由于其升温幅度突破了3.0度以上的前所未有水平,我们还需要持续观望。
但从规律来看,在陆气相互作用与天气条件方面,当厄尔尼诺在冬季达到峰值时,加拿大(特别是加拿大西部、中部以及安大略省部分地区)往往会出现更加温暖、温和的暖冬,同时安大略省周围通常会出现更干燥的气候条件。
这主要是因为厄尔尼诺改变了**急流(jet stream)**的路径。急流是高空大气中的强风带,直接引导着全球风暴路径和天气系统在不同区域间的位移。一旦急流路径发生偏移,降水分布、干湿格局以及冷暖气团的走向都会发生改变。
因此,通常我们可以预期一个偏暖、偏干的冬季。但每次厄尔尼诺都有其独特性,鉴于当前海表温度升温异常剧烈,如果原本偏干的趋势进一步加剧,是否会引发极端干旱?我们可能会面临比以往经验更为极端的状况。
英文原文
Janine Banff: Yeah. You know, so with this specific El Nino, we're going to have to just wait and see, wait it out and sort of see, we just because it's it's unprecedented. We haven't like reached this like 3.0 and, and, and higher before, but in general, when, when we are talking about El Nino and linking that to, you know, land atmosphere, interactions and weather conditions, Canada, especially Western Canada into central Canada and parts of Ontario, tends to see more of a warmer, more milder winters. When El Nino does peak, it usually peaks in the winter. And we tend to see milder winters. We tend to see drier conditions around Ontario as well.
And, you know, this is all because it it's shifting the jet stream. The jet stream is the winds in the higher part of the atmosphere, which really steers our, our, our weather. It steers our storm tracks and it veers it from one region to another. And so once that sort of shifts, it moves where we're going to see precipitation and where we're going to see drier versus wetter conditions and warmer versus cooler conditions.
So yeah, we can usually expect in general, a milder or milder winter, a drier winter winter. But every El Nino is different. So with this particular one, we're going to have to wait and see. However, when things are intensified, such as a sea surface, temperatures intensifying, becoming warmer, you know, that could potentially mean that our weather conditions that we see if if it's generally tends to be drier, will it be even more dry? Right. So we're going to be seeing possibly more extreme conditions than what we're used to.
天气与气候的本质区别及其叠加机制
Jeyan Jeganathan: 围绕厄尔尼诺的讨论,很多人常分不清气候变化与天气变化。有人曾向我打过比方:气候变化就像一个人的“性格”,而天气变化就像随时波动的“情绪”。请帮我们梳理一下两者的核心区别。
英文原文
Jeyan Jeganathan: Around this conversation of El Nino. You know, a lot of people were talking about climate change versus the difference between weather change. And some people have explained it to me as a little bit like climate change is like a personality and weather change is like a mood, which can kind of change here and there. Help me understand what is the key difference between those two?
Janine Banff: 当我们讨论天气与气候时,必须考虑**时间跨度(temporal scale)和空间尺度(spatial scale)**的差异。
你可以把“天气”理解为大气的短期状态,它随时都在变化——从每分每秒、每小时到每天、每周都在改变,包括昼夜温差变化(diurnal variations)以及气温引起的湿度波动。
而“气候”完全不同,它的尺度宏大得多。在气候学中,我们通常统计30年甚至更长时间周期的平均气象状态。你可以把它视为漫长岁月里大气的平均基准。比如从20世纪80年代到2000年代初这30年间的平均大气状态是怎样的,而未来30年又会发生怎样的偏移。这就是两者的核心差异。
英文原文
Janine Banff: Yeah. When we talk about weather and we talk about climate, we have to consider that the difference in the temporal, the time period that we're looking at and the spatial regions that we're looking at. Right?
So whether you can just think of it as a short term state of the atmosphere, and that those conditions, the state of the atmosphere can change from minute to minute, hour to hour, day to day, right, weeks to weeks.
With climate change, it's it's different. It's at a larger scale. Usually when climatology, we look at statistics for over 30 years and more. And so this is the average weather. You can think of it over many, many years, right? So so I would say that that's the main difference. So when we're looking at weather, weather change, weather can change from from day to night. This is what we call diurnal variations, right. Changes in weather conditions. Your humidity levels can change because of temperature.
But with climate we're looking at, you know, on a 30 year average, maybe from the 1980s to the early 2000, what was that average state of the atmosphere? And how is that going to be different from the next 30 years? Right. So that's, that's the difference. Yeah.
Jeyan Jeganathan: 那么,Janine,厄尔尼诺本身会受到气候变化的影响吗?
英文原文
Jeyan Jeganathan: So, Janine, how can an El Nino be affected by climate change?
Janine Banff: 当我们思考海表温度持续变暖时,必须认识到气候变化是人为活动引起的(anthropogenic)。
全球变暖不断抬高了海洋背景温度,而厄尔尼诺作为一种将暖水回推至美洲沿岸的自然年际波动,叠加在更高的基准温度之上,很可能会增强厄尔尼诺的强度、持续时间以及发生频率。
但目前仍有许多科学研究尚待完成。人类对这种超强厄尔尼诺现象的高精度观测记录时间还不够长。从统计学和气候学角度来看,我们需要积累更长周期的完整数据记录,才能确切解构和证实人为气候变化究竟在多大程度上、以何种机制重塑了厄尔尼诺事件。
英文原文
Janine Banff: Yeah. You know, when we think about a warming, warming sea surface temperatures, climate change is anthropogenic. It's human made. So when we're intensifying or increasing the sea surface temperatures, that's the background to this natural variability in a in an El Nino, which is also going to slosh out warm water back towards North America and South America. So it could potentially intensify the the strength of the El Nino, the so the intensity, the duration and the the frequency of these El Ninos.
But there's still a lot of studies that need to be done. We don't have a very long record of these really strong El Ninos yet. So from a statistical standpoint and a climatological standpoint, we need to get those records before we're able to parse through whether anthropogenic climate change is influencing and how it's influencing El Nino events.
Jeyan Jeganathan: 这次厄尔尼诺看起来注定要载入史册,但具体演变仍需拭目以待。Janine,非常感谢你为我们带来清晰透彻的科学解读。
