The Language of Climate Change

[Music]

climate change isn’t just changing the

natural environment

it’s changing language take the word

megafire

which was once the way we described our

largest and most destructive wildfires

that burned over a hundred thousand

acres

nowadays we have gigafires that burn

over a million like a 2020 fire in

california

that burned an area nearly three times

the size

of los angeles black summer

was a term coined by australians for

their recent bushfire season

due to the unusually intense fires that

burned an area more than

five times the size of vancouver island

and here in british columbia canada we

lived

through the smoke from fires in

washington and oregon this past summer

we can recall the effects the sting in

our eyes and lungs

sunny days hidden by a smoky blanket

but there were also the effects that we

didn’t see

as an ecologist watching these fires

burn

i saw carbon carbon stored in trees

shrubs and soils that took decades

sometimes centuries to accumulate

quickly combusted and sent into the

atmosphere as greenhouse gases

the same gases released by the burning

of fossil fuels

the main driver of climate change that

we’re facing today

and i saw all the climate benefits of an

intact forest

carbon removal as plants take co2 carbon

dioxide

out of the atmosphere as they grow i

watched those benefits

disappear as well and these wildfire

missions are nothing to scoff at

here in bc our two back-to-back extreme

wildfire seasons in 2017 and 18

each produced three times more

greenhouse gases

than all other sectors combined

meaning forests which are one of our

most important assets in the fight

against climate change

can just as easily be a liability

trees can and do regrow post-fire

building up carbon as they do

but building that carbon takes time

and in the fight against climate change

time is precisely

what we lack so

how did we get to an era of gigafires

and what can we do about it

let’s start by talking about fire

suppression a phrase that used to be

jargon but is now just part of our

general vocabulary

before this policy many landscapes in

north america burned regularly

due to fires ignited by lightning and

those ignited by indigenous people to

sustain healthy ecosystems and

communities

fire maintained ecological integrity and

landscape mosaics

forested stands clumps of shrubs

grasslands and bare ground

all intermixed this variation changed

the flow of fire across the landscape

and constrained the severity of many of

these burns

but european colonizers forcibly removed

indigenous communities from their land

and inhibited traditional fire

stewardship around the turn of the 20th

century

both canada and the united states

implemented comprehensive policies of

fire suppression

and effectively banned burning by

indigenous communities

intentionally excluding fire we

fundamentally altered

the structure character and resilience

of our forests

our landscapes became dominated by

conifers which in large continuous

stands can quickly carry and spread fire

and increase the risk of pest and

disease outbreaks like mountain pine

beetle

which has taken a staggering toll here

in bc

in the absence of regular fire and with

millions of beetle kill trees

our forests are packed to the brim with

fuel ready to burn

layered on top of these dangerous forest

conditions

is climate change which brings us not

only new words

but reinvigorates old words with new

meaning

words like unprecedented which i know

after 2020 none of us want to hear again

but

at the same time when it comes to

climate no other word captures

the moment that we’re in or where we’re

headed

in relation to today’s forests

unprecedented

applies to higher temperatures extended

droughts and rapid fire spread

so we see bigger fires more often that

are harder to control

and riskier to humans in relation to

today’s climate

unprecedented applies to atmospheric co2

concentrations

which ice cores tell us are higher than

any

time in the last 800 000 years

meaning higher than any time in the

history of our species

this is a direct consequence of fossil

fuel burning which governments around

the world have subsidized

even after the consequences were well

understood

despite language about the new normal

the changes to our climate are just

getting started

if we continue to burn fossil fuels we

will keep breaking records

and move deeper into an unprecedented

world

so what do we do

as the conditions of our world change we

must shift our thinking

re-examine our language and let words

take on new meaning

why because changes in language are a

precursor to action

and a first step towards change

the word conservation conjures ideas of

preservation

of landscapes untouched by human

activity

but in reality indigenous people have

been managing and shaping north

america’s landscape since time

immemorial

and now climate change is bringing human

influence to even

the most protected areas of the world as

temperatures shift and rain patterns

change

some forests will no longer be able to

support the species that we’ve expected

there for generations

instead of viewing conservation as the

preservation

of what once was we need the language of

conservation

to mean preparation for what will be

in a word we need resilience

ecological resilience so that our

forests can persist

and thrive in the face of tomorrow’s

wildfires

so that they can continue to support not

just our species

but all species that call these forests

home

so that forests can be part of the

solution and

actively remove carbon from our

atmosphere

but resilience like trust is

challenging to build but deceptively

easy to dismantle

thousands of years of evolutionary and

human history

created the resilient forests of our

past and it just took

over a single century of burning fossil

fuels

and suppressing fires to unravel the

whole

damn thing

those invested in continuing to burn

fossil fuels

embrace the language of moderation that

climate

action means each of us turning down our

thermostat by a few degrees or

simply abiding by smokey the bears

refrain that only you

can prevent forest fires but

what climate action demands is the

language of transformation

transforming how the energy that powers

a thermostat is generated

and transforming the conditions of

forests themselves

building resilience requires

unprecedented action

to match the scale of this crisis and an

acknowledgement

that climate change is not an individual

problem

but a systemic one not an issue of

choices

but of policies that’s

not to say that individual decisions

don’t matter

they’re just insufficient

because when it comes to climate change

our systems

have failed

all right that was heavy

but there are reasons for us to hope

because if

policies got us here policies can help

us get

out we could restore indigenous land

stewardship

and remove the bureaucratic barriers

that stifle the reintroduction of

traditional fire

we can replace the language of fire

suppression

with that of adaptive management which

is already practiced here in bc

but could be practiced at a much greater

scale

this means investing resources to create

jobs so we can physically remove

fuel from our landscapes by using

thinning or

prescribed burns but then also we need

to use that fuel

that carbon in ways that keeps it out of

the atmosphere

even after it’s left the forest

we could remove the word glyphosate a

powerful herbicide

from our forest management policies this

chemical is currently sprayed on

thousands of acres of regrowing forest

and promotes commercially valuable

species at the expense of hardwoods like

aspen

which can naturally moderate fire

behavior

and finally we have to eliminate fossil

fuel subsidies

which are in direct conflict with

provincial and federal

efforts to combat climate change because

when it comes to carbon without reducing

the amount of greenhouse gases that we

pump into the atmosphere

all the tree planting and forest

management in the world

won’t make a difference

the language of climate action is here

for

our taking what we need is the

collective courage to act

as individuals we must demand

transformative action from our elected

officials

and the systems they represent on our

behalf

we can proactively manage our forests

with carbon and tomorrow’s wildfires in

mind

we can reimagine the language of our

policies

to prioritize justice and climate action

and we can transform our systems to meet

the urgency of this

moment the urgency of our

moment by doing so

we give future generations a fighting

chance at resilience themselves

because while gigafires may be our

reality today

they don’t have to be our future

thank you

you

气候变化不仅在改变

自然环境,

它也在改变语言 以大火这个词

为例

,这曾经是我们描述我们

最大、最具破坏性的野火的方式

,烧毁了十万

英亩,

现在我们有燃烧

超过一百万的超级大火,就像 2020 年加利福尼亚发生的一场大火

烧毁的面积几乎

是洛杉矶黑色夏季

的三倍,这是澳大利亚人在最近的丛林大火季节创造的一个术语,

原因是异常强烈的大火

烧毁的面积是温哥华岛面积的五倍多

, 去年夏天,在加拿大不列颠哥伦比亚省,我们

经历了华盛顿和俄勒冈州火灾产生的烟雾,

我们可以回想起

被烟雾毯掩盖的阳光明媚的日子对我们眼睛和肺部的刺痛,

但也有我们

没有看到的影响

作为一名观察这些大火燃烧的生态学家,

我看到了储存在灌木和土壤中的碳碳,这些碳碳

需要几十年

甚至几个世纪才能积累

ulate 迅速燃烧并

作为温室气体排放到大气中

燃烧化石燃料释放的相同气体

是我们今天面临的气候变化的主要驱动力

大气中的

二氧化碳随着它们的增长

而消失,我看到这些好处也

消失了,这些野火

任务在不列颠哥伦比亚省在这里没有什么可嘲笑的,

我们

在 2017 年和 18 年连续两个极端野火季节

产生的

温室气体是其

三倍 所有其他部门加起来

意味着森林是我们

在应对气候变化方面最重要的资产之一,它

可以很容易地成为一种责任

树木,它们可以并且确实在火灾后重新生成

碳,

但建立碳需要时间,

而且在 与气候变化作斗争的

时间

正是我们所缺乏的所以我们是

如何进入一个 gigafires 时代的

,我们能做些什么

让我们从谈论开始 t

灭火 过去是

行话,但现在只是我们

在这项政策之前的一般词汇的

一部分 北美的许多景观

由于闪电点燃的火灾和

土著人民点燃的火灾而经常燃烧,以

维持健康的生态系统和

社区

火灾保持生态 完整性和

景观马赛克

森林林立 灌木丛

草原和裸露的地面

都混合在一起 这种变化改变

了整个景观的火势

并限制了许多此类烧伤的严重程度,

但欧洲殖民者强行将

土著社区从他们的土地上移走

并抑制了

周围的传统火灾管理 在 20

世纪之交,加拿大和美国都

实施了全面的灭火政策,

并有效地禁止了

土著社区的燃烧,

故意排除火灾 我们

从根本上改变

了森林的结构特征和恢复力

我们的景观变成了 以

针叶树为主,在大面积的连续

林分中可以迅速携带和传播火势

,增加病虫害爆发的风险,

例如山松

甲虫

在没有经常火灾的情况下,在不列颠哥伦比亚省造成了惊人的损失,

数百万甲虫杀死

了我们的树木 森林挤满了

准备燃烧的燃料,

层层叠加在这些危险的森林条件之上

是气候变化,它不仅给我们带来了

新词,

而且用新的意义词重振了旧词,

比如我知道

2020 年之后我们都不想听到的前所未有的词 再次,

同时在

气候方面,没有其他词可以捕捉

到我们所处的时刻或我们将要

前往

的地方与今天的森林有关

前所未有的

适用于更高的温度 长期

干旱和迅速蔓延的火灾,

所以我们看到更大的火灾更多

与当今气候相关的情况通常更难控制,对人类来说风险更大,

这适用于大气中的二氧化碳

浓度

冰芯告诉我们的比

过去 80 万年的任何时候都高,这

意味着比

我们物种历史上的任何时候都要高

这是化石

燃料燃烧的直接后果,即使后果很好

,世界各国政府也给予补贴

尽管有关于新常态的语言,但

我们的气候变化才

刚刚开始

我们的思维

重新审视我们的语言,让文字

具有新的意义

为什么因为语言的变化是

行动的先导,

也是改变

这个词的

第一步 自古以来管理和塑造

北美的景观

,现在气候变化正在给人类带来 随着温度的变化和降雨模式的改变,人类

甚至

对世界上最受保护的地区产生了影响,

一些森林将不再能够

支持我们几代人期待的物种,

而不是将保护视为

保护曾经我们需要的东西

保护

的语言意味着为将要发生的事情做准备

总之我们需要恢复力

生态恢复力以便我们的

森林能够

在明天的野火面前持续存在并茁壮成长,

以便它们不仅可以继续支持

我们的物种,

而且可以继续支持所有称之为这些的物种 森林为

家,

这样森林就可以成为

解决方案的一部分,并

积极从我们的大气中清除碳,

但是像信任这样的

弹性很难建立,但看似

容易拆除

数千年的进化和

人类历史

创造了我们过去的弹性森林

,它只是花了

一个多世纪以来燃烧化石

燃料

和扑灭大火以摧毁

整个

大坝

那些投资于继续燃烧

化石燃料的人

接受了温和的语言,即

气候

行动意味着我们每个人都将我们的

恒温器调低几度,或者

只是遵守冒烟的做法。熊

克制说只有你

才能防止森林火灾,

但气候行动需要 是

变革的语言 转变

为恒温器提供动力的能源的产生方式

并改变森林本身的条件

建立复原力需要

前所未有的行动

来应对这场危机的规模,并

承认气候变化不是个人

问题,

而是系统性问题 一个选择问题,

而是一个政策问题,这

并不是说个人

决定无关紧要,

它们只是不够的,

因为在气候变化方面,

我们的系统

已经失败

了,这很严重,

但我们有理由希望,

因为如果

政策 让我们来到这里 政策可以帮助

我们

摆脱困境 我们可以恢复土著土地

管理

消除阻碍重新引入

传统火灾的官僚障碍

我们可以用适应性管理的语言代替灭火语言

我们可以

通过减薄或规定的燃烧从物理上从我们的景观中去除燃料,

但是我们还

需要使用这种燃料

,即碳

即使在离开森林后也不会进入大气,

我们可以删除草甘膦这个词,一种

强大的

除草剂 我们的森林管理政策 这种

化学物质目前喷洒在

数千英亩的再生森林

中,

以牺牲像

白杨

这样可以自然缓和火灾

行为的硬木为代价来推广具有商业价值的物种

,最后我们必须取消

与省级直接冲突的化石燃料补贴

和联邦政府

对抗气候变化的努力 因为

当涉及到碳而不

减少我们排放到大气中的温室气体量时,

世界上所有的植树和森林管理

都不会产生

影响气候行动的语言就在这里

我们需要的是

作为个人的集体勇气

我们必须

从我们所选的

官员

和他们代表的系统中要求转变措施,

我们可以主动管理我们的森林

和明天的野火,

我们可以重新想象我们政策的语言,

以优先考虑正义和气候的政策语言 采取行动

,我们可以改变我们的系统,以应对

一刻的紧迫性

通过这样做,

我们为后代提供了一个对抗

自身复原力的机会,

因为虽然 gigafires 可能是我们

今天的现实,

但它们不必成为我们的未来,

谢谢 你

你你
