野火季展望
主持人: 又到了火灾季,最近我们不断打破纪录,而且是那种你不想打破的纪录。那么今年的前景如何?我们准备好了吗?Mike Flanagan 是不列颠哥伦比亚省坎卢普斯汤普森河大学的野地火灾学教授。很高兴能连线到您,Mike。您好吗?
Original English
Host: It's fire season again, and lately we're breaking records, the kind you don't want to break. So what's the outlook for this year and are we prepared? Mike Flanagan is a professor of wildland fire at Thompson Rivers University in Kamloops, B.C. Great to have you on the line, Mike. How are you doing?
Mike Flanagan: 很高兴和您一起。我很好。
Original English
Mike Flanagan: Great to be with you. I'm doing great.
主持人: 好的。让我们来看看加拿大近期的野火历史。这张图表来自加拿大跨部门森林火灾中心。显示的是从 2010 年左右开始,加拿大每年烧毁的总面积。我们可以看到情况相对稳定。然后在 2020 年突然下降,而在屏幕右侧的 2023 年和 2025 年出现了巨大的飙升。近年来似乎出现了极端的大起大落。那么 Mike,不得不问,2026 年在这个国家,野火方面将为我们带来什么?
Original English
Host: All right. Let's take a look at Canada's recent wildfire history. This chart is from the Canadian Interagency Forest Fire Centre. Shows the total annual area burned in Canada from about 2010. We can see things are fairly stable. Then a sudden drop in 2020 and a huge spike there just on the right hand of the screen in 2023 and again in 2025. There seems to be extreme spikes both up and down in recent years. So Mike, one has to ask, what does 2026 have in store for us in this country when it comes to wildfires?
Mike Flanagan: 嗯,首先,一个重要的免责声明。现在是四月,所以你永远不知道会发生什么。这个火灾季取决于火灾期间每天的天气以及我们看到的点火数量。我说的天气是指炎热、干燥、有风的天气。如果我们遇到这些天气,加上点火,这个夏天可能会很忙。话虽如此,但有一些指标预示着可能会发生什么。一个就是干旱。加拿大的大部分地区异常干燥或处于干旱状态,这为活跃的火灾季奠定了基础。此外,夏季的预测是,加拿大的许多地区,特别是西部地区,将是炎热的夏天,而且有些地方会很干燥。所以这也强烈预示着一个活跃的火灾季。而且你知道,我们越暖和,看到的火灾就越多。人们会问,为什么会这样?嗯,我们越暖和,火灾季就越长,我们越暖和,闪电就越多。我们越暖和,它就会更好地烘干燃料,也就是森林地面上的枯死燃料,如松针、树枝、树叶。这样火就更容易着火,无论是来自闪电还是人为活动。而且可燃烧的物质也更多,这会导致强度更高的火灾,难以甚至不可能扑灭。
Original English
Mike Flanagan: Well, first, a big disclaimer. It's April, so you know what's going to happen. This fire season depends on the day to day weather during the fire season and the number of ignitions we see. And by weather I mean hot, dry, windy weather. We get those and ignitions. It could be a busy summer. Having said that, though, there are indicators that suggest what may happen. One is drought. Much of Canada is abnormally dry or in drought, and that sets the stage for an active fire season. Also, the summer forecast is for many parts of Canada, especially the West, to be a hot summer and and in places dry. So that also is a strong indicator of active fire season. And you know, the warmer we get, the more fire we see. And people say, why is that? Well, the one we get, the longer the fire season, the warmer we get, the more lightning we expect. The longer the warmer we get it. It gets better drying out the fuels, the dead fuels on the forest floor, needles, twigs, leaves. So it's easier for a fire to start, whether it's from a lightning strike or from human activities. And more of that stuff's available to burn, which leads to higher intensity fires that are difficult to impossible to extinguish.
主持人: 您提到了干旱。目前省内是否有特别的地区是您正在关注的、令人担忧的区域?我知道,正如您所说,现在还很早,但您提到了东部或西部的一些地区。
Original English
Host: You had mentioned drought. Are there particular areas right now in the province that you're kind of keeping an eye on in terms of areas of concern? I know, again, as you said, quite early, but areas, particularly in the east or in the West, as you mentioned.
Mike Flanagan: 在加拿大范围内,主要是西部地区,但在安大略省的“肘部”区域,你知道,安大略省和马尼托巴省的那个部分,像一个肘部一样的地带,那个区域,你知道,西北安大略省,那是 2026 年火灾季在安大略省的重点区域。
Original English
Mike Flanagan: So within Canada, you know, it's mostly the West, but within Ontario around the elbow. You know, that part in Ontario and Manitoba, where bands like an elbow, that area, you know, northwestern Ontario, that's the prime territory for Ontario for this 2026 fire season.
预测能力与新现实
主持人: 据我所知,野火预测是出了名的困难,但您在这方面做得相当不错。我很想知道,随着技术的发展,我们是否在野火预测方面做得越来越好?更重要的是,我们今年(2026 年)的预测,是否将成为加拿大新现实的重要指标?
Original English
Host: From what I gather, forecasting for wildfire is notoriously difficult, but it is something that you do quite well. And I am curious, are we getting better at forecasting wildfires as the technology gotten better? And more importantly, is what we're going to forecast this year in 2026, is this going to be a big indicator as to what sort of the new realities are for Canadians?
Mike Flanagan: 是的。首先,我们已经经历了三个非常活跃的火灾季。过去三年里,我们大约有 8% 的森林被烧毁。我们从未见过这样的三年。我过去总是说,哦,你知道,有些年份会更凉爽湿润,我们会得到喘息的机会。而且,你知道,我仍然相信对于安大略省或魁北克省这样的地区来说,情况确实如此。但在全国范围内,我们是一个大国。所以总会有一些地方会又热又干,我们就会发生点火,然后就会有一个活跃的火灾季。所以对我来说,2026 年是一个试金石。如果又是糟糕的火灾季,那么我预计新的现实将是,大多数年份都会是糟糕的火灾季。而且你知道,对于多伦多的居民来说,你的住处,你知道,不会因为世界之火而烧毁。然而,你的生活质量可能会在几周内直线下降,因为烟雾。一千公里外火灾产生的烟雾就能让你的生活变得痛苦不堪。你知道,这就是我们现在正在经历的。至于预测,是的,我们正在变得更好,尤其是在预测极端火灾天气方面。而且,你知道,稍微退一步说,野火的发生是有规律的,这是普遍适用的。它适用于安大略省,也适用于亚马逊雨林。它有三个要素。第一是燃料(植被)。有多少,多干,什么类型。第二是点火源(人为和闪电)。在加拿大和安大略省,大约是各占一半。第三是炎热、干燥、有风的天气。所以如果我们能预测到炎热、干燥、有风的天气,点火源就有点棘手了。但确实有模型可用,我们也知道燃料在哪里。燃料是相当静态的,它的干燥程度确实会每天变化。
Original English
Mike Flanagan: Yeah. So first, you know, we've had three really active fire seasons. About 8% of our forest has burned in the last three years. So we've never seen three years like this. I always used to say, oh, you know, some years will be cooler and wetter and we'll get a break. And, you know, I still believe that regionally for like Ontario or Quebec, that's the case. But nationally, we're a big country. So somewhere it's going to be hot and dry and we get ignitions and we're going to have an active fire season. So to me, 2026 is a litmus test. If it's another bad fire season, then I expect the new reality is that most years are going to be a bad fire season. And you know, for folks in Toronto, your place, you know, isn't going to burn down from world on Fire. However, the quality of your life can be in the tank for weeks because of smoke. Smoke from a fire 1000km away can make your life miserable. And you know, that's what we're living with now in terms of forecasting, yes, we are getting better, especially, you know, forecasting extreme fire weather. And, you know, stepping back just for a second, there's a recipe for wildfire and it's universal. It applies to Ontario. It applies to the Amazon. And it has three ingredients. First is fuel vegetation. How much, how dry, what type. Second, ignition people and lightning. And in Canada and in Ontario, it's about 50 over 50. And third hot, dry, windy weather. So if we can forecast the hot dry, windy weather, ignitions are a little more tricky. But there are models out there and we know where the fuel is. That's pretty static, how dry it is that that does change day to day.
气候变化的影响
主持人: Mike,气候变化在多大程度上应该为我们近年来看到的这些破纪录的野火负责?
Original English
Host: Mike, to what extent is climate change responsible for these recent record breaking wildfires that we've been seeing?
Mike Flanagan: 目前在加拿大,我们十年的平均年烧毁面积约为 400 万公顷。这可能对您的观众来说意义不大。它大约是安大略湖大小的两倍。这是一个巨大的区域。在 70 年代,你知道,你展示了过去 15、16 年的数据。我们的记录可以追溯到 1950 年代,而在 1970 年代,烧毁面积约为 100 万公顷。所以加拿大的烧毁面积几乎翻了四倍。我将这主要归因于人为引起的气候变化。我不能再清楚地说明这一点了。美国西部地区的烧毁面积也翻了四倍。这是因为我们正在变暖,人们会问,为什么温度在这里如此重要?我不是指像麦克默里堡大火这样的单一场火灾。我指的是像安大略省这样大面积、更长时间内的火灾。这是因为我们的火灾季正在变长,不是每年都变长,但平均而言,火灾季正在变长,因为我们变得更暖和了。随着气温升高,我们预计闪电会更多。50% 的火灾是由闪电引起的,但它们却造成了我们所烧毁面积的 90%。最后一个原因是,随着温度升高,它非常有效地烘干了燃料,这意味着火更容易开始和蔓延。
Original English
Mike Flanagan: So in Canada right now, our ten year average annual burn is about 4 million hectares. And that probably doesn't mean much to your audience. It's about twice the size of Lake Ontario. It's a huge territory. In the 70s, you know, you showed data for the last 15, 16 years. Our records go back to the 1950's, and in the 1970's it was about 1 million hectares. So it's almost a quadrupling of area burned in Canada. And I attribute this largely not solely to human caused climate change. I can't be any clearer than that. Western United States has also seen a quadrupling of area burn. And it's because we're getting warmer and people say, well, why is temperature so important here? I'm not talking about an individual fire like the Fort McMurray fire. I'm talking about fire over a large area like Ontario and over a longer period of time. And it's because our fire season is getting longer, not every year, but on average, our fire season is getting longer because we're warmer. We're expecting more lightning as it gets warmer. 50% of the fires are started by lightning, but they're responsible for 90% of the area burned in. The last reason is as the temperature warms, it's very effective at drying out fuels, which means it's easier for fires to start and spread.
消防能力与准备
主持人: 我想更好地了解我们省的消防能力。我们跟得上这些火灾的规模和强度吗?正如您所说,火灾季越来越长。处理这些火灾需要大量人力,而且会持续数天。所以请帮我理解一下,我们省有能力应对吗?
Original English
Host: I want to get a better understanding of our firefighting abilities in this province. Are we keeping pace with the scale and intensity of these fires? As you mentioned, fire season is getting longer. There is a lot of, you know, you need a lot of manpower on the ground to deal with these as well if they're extending for days. So help me understand, do we have the ability here in the province to deal with it?
Mike Flanagan: 首先,加拿大的火灾管理机构是世界上最好的之一,而安大略省在加拿大也是最好的。他们是专业的,训练有素的。我们有足够的资源吗?可能不足以应对我们过去几年看到的火灾。有一个叫做国家准备水平(NPL)的东西,有五个级别,级别五意味着我们在加拿大没有资源了。过去三年,我们一直处于 NPL 国家准备水平五级。有两三天处于这个五级水平,意味着没有资源。我们不得不从美国、南非、欧洲或澳大利亚引进资源。但是,我必须说,安大略省采用的“适当响应”方法是这个时代应对火灾的正确方式。这意味着他们会评估发生的每一场火灾。如果一场火灾发生在距离蒂明斯两公里处,这是一场不希望发生的火灾,我们会去扑灭它。如果一场火灾发生在蒂明斯以北 100 公里处,他们会评估:它在未来一两周内会蔓延到哪里?它会影响基础设施或社区吗?他们实际上会评估它是否会有益。他们是唯一考虑野火益处的火灾管理机构。是的,确实有益处,比如东部森林的云杉芽虫,西部森林的松甲虫,火灾是消灭这些害虫和疾病的绝佳媒介。这只是大自然在工作。所以火灾管理应该允许大自然在可能的时间和地点做它该做的事。而且,你知道,这个决定必须在五分钟内迅速做出,因为当火灾发生时,如果它是一场不希望发生的火灾,你越早处理它越好。这就是为什么,你知道,立即报告火灾。310 火灾 911,你知道,如果你看到火灾,立即报告,尤其是在这个时候,春天,因为你有大量的去年的枯死有机物。今年这个时候开始的大多数火灾都是由人为引起的。
Original English
Mike Flanagan: So first of all, Canadian fire management agencies are among the best in the world and Ontario's among the best in Canada. They are professional, well trained. Do we have enough resources? Probably not for the fires we've been seeing the last few years. There's something called the national preparedness level, and there's five levels, and level five means we have no resources in Canada. We've been in NPL National Preparedness Level five for the last three years. 2 or 3 days have been at that level five, which means no resources. And we have to go with the States or South Africa or Europe or Australia to bring them in. But, you know, I will say that the approach that Ontario uses, and I'll call it appropriate response, is the way to go to deal with fire in this age. And what that means is they make an assessment on every fire that occurs. So a fire starts two kilometres from Timmins that's unwanted fire, and we go put it out. If a fire starts 100km north of Timmins, they look at, you know, where will it spread in the next week or two? Will it impact infrastructure communities? And they actually look at whether it would be beneficial. They're the only fire management agency that considers the benefits of wildfire. And yes, there are benefits, things like spruce budworm in the East Mountain, pine beetle in the west fires a great agent knocking down these pests and diseases. And it's just Mother Nature doing her work. So fire management should allow Mother Nature when and where possible to do her thing. And you know, these this decision has to be made rapidly within five minutes because when a fire starts and it's an unwanted fire, the sooner you get to it, the better. And that's why, you know, reporting a fire right away. 310 fire 911 is, you know, if you see a fire report right away, especially this time of year, it's spring because you have a lot of dead organic material from last season. And most of the fires started this time of year are by people.
政府层面的准备
主持人: 鉴于此,我很好奇加拿大应该做些什么,无论是联邦层面还是省级层面,来更好地为未来做准备?据我所知,加拿大政府没有类似美国联邦紧急事务管理局(FEMA)那样的“一站式”机构来处理这些担忧。但其他各级政府能做些什么呢?
Original English
Host: With that being said, I am curious what should Canada be doing more, whether it's at the federal level or the provincial level, to better prepare for what is to come? As I understand, you know, the Canadian government doesn't have sort of the equivalent in the US as FEMA, the the Federal Emergency Management Agency, something that, you know, all in one can kind of deal with the with the concerns here. But what can the other levels of government be doing?
Mike Flanagan: 嗯,我刚才提到我们资源短缺。所以有不同的方式可以给各省提供资金。你可以购买水上轰炸机。实际上,他们今年正在外包水上轰炸机的合同。没错。这是一个活跃的火灾季。但我认为拥有一个联邦紧急事务管理机构是明智之举。我们应该研究世界各地正在做的事情,并将其应用于加拿大国情,以便我们能够应对洪水、飓风、火灾。你知道,比如飓风,有一个飓风中心,我们也应该为火灾建立这样的机构。实际上,我将开始发布一份全国性的每周火灾天气展望,并将其发布在网上。这样我们就可以随时了解即将发生的情况,因为我们大多数时候都能预知极端火灾天气的到来。这意味着要做好准备。是的,正如我所说,它们更难预测,但我们确实知道现有火灾的位置,我们也能大致知道闪电可能在哪里发生。因此,我们可以更好地准备,并提前将资源调往那些地点,做到更主动。应急管理有几个阶段:预防、减缓、准备、响应和恢复。火灾管理在响应和准备方面做得很好。他们做得相当不错,但我们可以更主动一些。当然,像预防和减缓这样的事情,你每花一美元在那里,通常就能在日后的灾害成本上节省五、十、十五美元。
Original English
Mike Flanagan: So, you know, I just mentioned we're short on resources. So there's different ways you could give money to the provinces. You could buy water bombers. And actually they're contracting water bombers out this year. Correct. It is an active fire season. But I think having a Federal emergency Management agency is the way to go. We should explore what's being done around the world and apply that to the Canadian context so that we can deal with floods, hurricanes, fires, you know, like hurricanes, for example. There's a hurricane centre and we should be doing that for fire. And actually, I'm going to start a weekly fire weather outlook for the country and post it online. So we can kind of keep an eye on what's coming because we can tell most of the time when that extreme fire weather is coming. And that means be prepared. And yeah, as I said, they're more difficult, but we do know where the existing fires are, and we can kind of know where the lightning may occur. And so we can be better prepared and move resources ahead of time to those locations and being more proactive. Emergency management has phases prevention, mitigation, preparedness, response and recovery. Fire management is great at response preparedness. They're pretty good, but we can be a little more proactive. And of course, things like prevention and mitigation for every dollar you spend there, it usually saves you five, ten, $15 down the road in disaster costs.
个人与社区准备
主持人: 我想给在这里观看的安大略省观众以及加拿大其他地区的观众一些想法和建议。我们省有大片的农村社区和城镇。我们也有城市中心。所以对于那些观看的人来说,他们应该了解今年夏天野火风险的一件事是什么?以及他们如何能更好地做好准备?
Original English
Host: I want to get some thoughts and ideas for our viewers who are watching here in Ontario and those in Canada. We have some vast areas of rural communities and towns in this province. We also have urban centres. So for those who are watching, what's one thing that they should understand about wildfire risk this summer and how they can be better prepared?
Mike Flanagan: 遵守火灾禁令。如果你身处高风险地区,如果你在一个被森林环绕的社区,特别是针叶林,它支撑着我们所说的树冠火,火势从林地蔓延到树冠。那些是高强度火灾,是问题的根源。准备好一个应急包。你知道,如果你看到火灾,立即报告:310 火灾 911。并规划好逃生路线,特别是如果你的社区只有一条进出道路,那会是个大问题。或者如果你是一个飞行社区(仅通过航空交通连接的社区)。火灾不成比例地影响着原住民社区以及北部偏远社区,这些社区没有像道路这样的逃生路线。所以,你知道,要留意省里发布的火灾天气预报,并在危险等级很高时提醒公众。他们实际上与工业界有协议,在火灾危险期减缓或停止作业。所以请密切关注。如果你看到烟雾,立即报告,并准备好在火势靠近时撤离。
Original English
Mike Flanagan: So observe fire bans. If you're in a higher risk location, if you're in, you know, a community surrounded by forests, especially if it's a conifer forest, which supports what we call a crown, fire spreads from the forest floor to the tops or crowns of the tree. Those are the high intensity fires that are the problem. Have a go bag ready. And you know if if you see a fire report right away. 310 fire 911 and have escape routes planned, especially if your community with only one road in or out, that can be a real issue. Or if you're a fly in community, I mean, fire disproportionately affects indigenous communities in northern remote communities where you don't have escape routes like a road or two. So, you know, just keep an eye on the, you know, the province will have fire weather forecasts and alert the public when things are high, high danger. And they actually do have agreements with industry to either slow down or shut down during periods of high fire danger. So just stay tuned. And if you see smoke, you know, report it right away and be prepared to leave if it's close by.
Fire Smart 计划
主持人: 人们应该了解Fire Smart Canada计划的哪些信息?
Original English
Host: What should people know about the Fire Smart Canada program?
Mike Flanagan: Fire Smart 有七项原则。你知道,我们需要做的是在高风险地区成为 Fire Smart 社区。关键在于,这真的需要强制执行,因为,你知道,像易燃建筑材料,紧邻你家房屋的易燃材料,特别是0 到 1.5 米的区域。它应该没有易燃材料。火灾通常通过余烬雨进入社区,小的燃烧的树枝、树皮,有时还有松果。这就是火灾如何蔓延到社区的。但问题是,如果你离邻居很近,而他们不是 Fire Smart 的,那些余烬就会点燃他们的房子,然后火就会从结构蔓延到结构。所以即使你做得一切都对,你也可能被烧毁,因为它没有得到普遍执行。我举个例子,贾斯珀。不幸的是,2020 年小镇三分之一被烧毁了。现在新建的建筑都遵循 Fire Smart 原则。强制要求建筑材料不能是易燃的。并且 0 到 1.5 米的区域必须没有易燃材料。所以我们正在走在这条路上,安大略省支持 Fire Smart。我相信他们正在增加对它的资助,但我们真的需要考虑通过法规来强制执行,因为如果只是自愿的,它就不会发生。
Original English
Mike Flanagan: So Fire Smart has seven principles. And you know, what we need to do is be Fire Smart communities in high risk locations. And the thing is, it really needs to be mandatory because, you know, things like flammable building materials, flammable material right adjacent to your home, especially that 0 to 1.5 metre zone. It should be free of flammable material. A fire typically enters a community through a rain of embers, little burning bits of twig bark, sometimes pine cones. And that's how the fire spreads into a community. But the problem is, if you're close to your neighbour and they're not Fire Smart, those embers will catch their house on fire, and then it will spread structure to structure. So even if you do everything right, you can be toasted because it's not done across the board. And I'll give you an example, Jasper. Unfortunately, a third of the town burned down in 2020 for the new builds are making to the Fire Smart principles. Mandatory building materials cannot be flammable. And that zone 0 to 1.5 metres has to be free of flammable material. So we're on the path and Ontario supports Fire Smart. I believe they're increasing funding for it, but we really have to look at making it using regulations because if you make it voluntary, it won't happen.
主持人: Mike,我们就先到这里。非常感谢您今天为我们详细解读。

Host: Mike, we are going to end things there. Thank you so much for breaking this all down for us today.
Mike Flanagan: 我的荣幸。
