How Climate Change is Affecting Our Worlds Water

since

as long as i can remember i’ve had a

deep connection with the ocean

i grew up in and out of the water seeing

the ocean as one of the most mysterious

captivating and powerful horses in the

world

i quickly got involved with ocean

advocacy at a young age

starting an ocean focused environmental

club at my school

and working with a flurry of ocean

related environmental groups

much of the time when we talk about

climate change we exclusively talk

about how it’s affecting the land from

deforestation

to desertification however the ocean

covers

71 percent of the earth’s surface we are

far more reliant on it and our water

than we like to think

the world’s water systems also connect

us

which brought me to work on ocean

conservation and water issues globally

specifically i’ve had the opportunity to

lead think ocean

a youth global network spanning 15

countries

that works on raising awareness of an

action on

the intersection of climate change in

our ocean

over the years my experiences have

taught me of the magnitude of our

environmental challenges

it’s shown me the issues of plastic

pollution in cameroon the recession of

the glaciers

in the alps in italy the rise of sea

levels in egypt

the cost of air and water pollution in

india and much more

however most of all i found that i had

to

unlearn many of the ways i used to think

about climate change

when first learning about

environmentalism many of us

are told that we have to make individual

choices to protect our planet

recycling taking shorter showers eating

sustainably

however i’ve come to learn that climate

change

and its many facets are not

individualistic

they are systematic therefore we must

critically review our system and social

tendencies that got us to where we are

today

for example when most people hear

climate change

they generally think of an increase in

temperatures and destruction of the

environment

however we need to reframe our

perceptions of this crisis

to instead focus on its human

implications

it could bring widespread economic

fallout

unprecedented mass relocations of people

and threaten global stability today

let’s discuss how our water will be

affected and delve into what makes this

issue

so hard to solve in my time as a youth

ocean advocate

i’ve had i’ve been able to work on water

related issues in egypt and south asia

and their local crises demonstrate the

urgency of today’s challenges

therefore let’s first turn to the rising

seas

in egypt specifically let’s zoom into

alexandria to examine how this issue

poses a threat

to local coastal communities pictured

here

in the above side we can see that much

of the nile river delta

where alexandria is located is at or

below sea level which corresponds to the

colors blue

and light green alexandria is the second

largest city in egypt with highly

populated areas surrounding it

it is both geographically and

socioeconomically vulnerable to the to

rising sea levels

a research paper published in 2015 found

that an increase in just a half meter

in sea levels could inundate most of its

beaches

and without effective adaptation could

displace

about two million people

another half meter could displace more

than six million people

well the sea is rising and it’s

projected that by 2050

there will be a rise in more than a half

meter of water on egyptian coasts

and it’s expected to eventually rise to

a full meter

it’s also projected that egypt’s

national agricultural sector

could be cut in half by 2060 due to

groundwater being contaminated with salt

resulting in a potential destabilization

in regional grain supply

and the economy these challenges

regardless of if we recycle eat

sustainably

turn off the lights when we live the

room are still happening

instead we need large scale structural

changes to prepare

communities for what’s to come and

mitigate future costs

however sea level is not exclusive to

alexandria

and it’s not exclusive to egypt it’s a

global threat

let’s zoom out to see the implications

of this issue across the globe

pictured here is a map showing the 2060

projected populations of people living

in areas

most at risk to sea level rise which are

called low

elevation coastal zones or lecz for

short

currently this is where 10 percent of

the global population lives

sea level rise and its corresponding

effects are highly complex

contingent on environmental political

and socioeconomic factors however

estimates range from anywhere from

88 million to 1.4

billion people who will eventually be

displaced due to sea level rise

therefore inundation could lead to

hundreds of millions of people

forced to move domestically or even seek

asylum internationally

besides the obvious threats that this

will have towards the communities

affected

it could also threaten our global system

however

there are many other ways that climate

change can affect our future

let’s now turn to the issue of water

scarcity which is a very real

and present issue that could be

exacerbated due to the effects of

climate change

let’s zoom in to south asia which is

home to one of the worst

water crises in the world pictured here

the deeper the shade of red the more

severe water stress is being experienced

in that part of the map currently

only 20 percent of pakistan’s population

have access to safe drinking water with

the remaining 80 percent

looted by sewage fertilizer pesticides

or industrial effluents and this

pollution is the culprit for

30 of deaths nationally across pakistan

likewise india is facing severe water

shortages

a 2019 report by researchers out of mit

found that 600 million people for

context

that is nearly twice the size of the

united states

face high to extreme water scarcity

another report by media young projects

that the crisis will only get worse

with national water demand expected to

be double that of available supply by

as the climate continues to change and

it continues to warm

it threatens to eliminate key sources of

water

the indus river basin a vital river

system that both

india and pakistan rely on also

relies on glaciers however these

glaciers are disappearing

causing salt water to creep its way into

the rivers

and the amount of water available to

decrease

further weather patterns have become far

less predictable

and droughts more prolonged threatening

to make their water crisis

only worse yet as with sea level rise

water scarcity is not exclusive to south

asia it’s a global threat

let’s now zoom out to see how this is

affecting the rest of the world

the above map shows the degree of water

stress

expected for each country by 2040 with a

darker shade of red corresponding with

more water stress

currently 2.4 billion people

are living within watersheds that are

experiencing water scarcity

and similar to pakistan and india the

effects of climate change

threaten to exacerbate this shortage

threatening both access to safe drinking

water

as well as the stability of various

industries reliant

on water supply unfortunately the

effects of water scarcity

sea level rise or other issues related

to climate change

will not be distributed equally poorer

communities

and people of color are poised to be the

most

affected climate gentrification is

happening

right now with folks being pushed into

less hospitable areas

and areas more likely to be hit the

hardest by the effects of climate change

let’s now turn to new orleans and see

how the damages from hurricane katrina

demonstrate the environmental racism

present around the world

here are two maps one showing the wealth

disparities

the percent of poverty in each area of

the city which is

signified by shades of blue and one

showing the percent of each part of the

city

that was predominantly black also

signified by the color blue

new orleans has a history of segregation

and this systematic oppression which

contributes

towards keeping communities of color in

poverty also put them at a higher risk

of the effects of climate change

here we see the deaths per ward of the

city

it is startlingly aligned with the

demographic makeup of the city

showing that poor communities and

communities of color

were the hardest hit by the disaster

unfortunately this is a trend that can

be seen elsewhere

from black and brown new yorkers being

hit hardest by hurricane sandy

to minority communities and poorer

communities being

again and again most harshly affected by

natural disasters

those same communities then take longer

to recover

due to higher costs and generally having

less savings

magnifying pre-existing wealth

disparities

now a major question presents itself

if these are the risks and we know the

risks

why aren’t we acting now why aren’t we

making the necessary changes

to prepare for our future well to

preface this

i just want to acknowledge that people

both young and old

are working day in and day out to build

a better future

the biggest obstacle to solving slow

moving crises like climate change

and others is the human tendency of

temporal discounting

we discount the future and prioritize

the present

similarly we discount costs seeing them

as less impactful

or pressing the further on the horizon

they sit

as a student i’m a lot less stressed

about a 30 page paper

assigned a month before it’s due than a

day before stay

this systematic procrastination can give

us a

dangerous sense of complacency however

without acting

right now further costs will accumulate

and could build to an insurmountable

amount

therefore we need to reframe the ways we

think about our decisions

and a great way to reframe our thinking

is through intergenerational action

and elevating the role of young people

in our decision making

young people gen z folks like myself

we will be forced to reckon with the

future being created today

whereas past environmentalists advocated

for future generations

those generations are here now

in the form of today’s youth this is why

the actions of youth organizations

like fridays for future zero hour the

think ocean society extinction rebellion

and many others

are so integral for acting on today’s

crises

youth climate coalitions have mobilized

millions

of people to organize in support of

climate action

protesting for change climate change

is an existential threat to our world

my generation and future generations and

these demonstrations

have helped to reframe the dialogue on

climate change

for example i was able to attend the

2019

u.n climate summit many of the world’s

leaders heads of states

and even leaders of municipalities were

present

their words were comforting but the

summit was only really notable due to

youth such as greta bloomberg

who reprimanded elected representatives

for inaction

this reprimanding which youth activists

by the way have been doing for

years at such events has put pressure on

our leaders

compelling them to take this crisis more

seriously

however every successful environmental

movement

has been intergenerational whether with

advisors

funders co-organizers or participators

even the most youth-led movements

benefit from

working with people of all ages

this focus isn’t just a matter of

narrative either

but it’s a matter of action of making

space

for future leaders it is vital that

members of generation z

are given seats at the decision-making

table and given more opportunities to

get involved

now this does not mean deferring all

responsibility

and decisions to youth this means

building intergenerational coalition

to address problems together

today we only brushed the surface of

climate change

examining only a few facets of this

far-reaching threat

we spoke about the upwards of a billion

people affected by sea level rise

the 2.4 billion people currently

affected by

water scarcity and how climate change

disproportionately affects communities

of color and poorer communities

however it’s important to remember that

much of what we’ve talked about

is not set in stone we do not know

the full extent of what climate change

will bring

however we do know that there will be

costs

and we know that the decisions we make

now

will define the magnitude of tomorrow’s

challenges

regardless of what we’ve discussed today

i consider myself an optimist

i see incredible hope in building a

better future a more just future

and truly tackling these issues together

however we can’t use the same archaic

methods that got us into this mess

moving forward we need to make space for

and empower young voices and the voices

of those that are most

adversely affected by this crisis we

need to face the great challenges ahead

of us

instead of shying away we are living

through the most formidable emergency

this world

has ever seen let’s start acting like it

thank you

从我记事起,我就

与海洋有着深厚的联系,

我在水中和水中长大,

将海洋视为世界上最神秘、最

迷人、最强大的马之一,

我很快就参与了海洋

倡导活动 年轻时

在我的学校创办了一个以海洋为重点的环保俱乐部,

并与一系列与海洋

相关的环保组织合作

大部分时间当我们谈论

气候变化时,我们只

谈论它如何影响土地从

森林砍伐

到荒漠化,但是海洋

覆盖了

71 地球表面的百分比我们

对它和我们的水的依赖程度远远

超出我们的

想象世界的水系统也将

我们联系在一起

,这使我在

全球范围内致力于海洋保护和水问题,

特别是我有机会

领导思考海洋

一个跨越 15 个国家的青年全球网络

,致力于提高人们

对气候变化在

我们海洋中的

交叉点采取行动的认识 这些年来,我的经验

告诉我环境挑战的严重性

它向我展示了

喀麦隆的塑料污染问题 意大利阿尔卑斯山冰川的衰退

埃及

的海平面上升 印度的空气和水污染成本

还有更多,

但最重要的是,我发现当我第一次了解环保主义时,我不得不

忘记我过去

对气候变化的

许多

看法 可持续饮食

但是我开始了解到气候

变化

及其许多方面不是

个人主义的,

它们是系统性的,因此我们必须

批判性地审查我们的系统和社会

趋势,这些趋势使我们达到

今天的水平

,例如,当大多数人听到

气候变化时,

他们通常 想想

温度的升高和环境的破坏,

但是我们需要重新构建我们

对环境的看法 这场危机

转而关注其对人类的

影响

它可能带来广泛的经济

影响

前所未有的大规模人口迁移

并威胁全球稳定 今天

让我们讨论一下我们的水将如何

受到影响并深入研究是什么让这个

问题

在我年轻的时候如此难以解决

海洋倡导者

我已经能够

在埃及和南亚处理与水有关的问题

,他们当地的危机表明了

当今挑战的紧迫性,

因此让我们首先转向埃及不断上升的海平面

,让我们放大到

亚历山大港,看看如何 这个问题

对上

图所示的当地沿海社区构成威胁

我们可以看到亚历山大

所在的尼罗河三角洲大部分地区

处于或

低于海平面,对应于

和浅绿色 亚历山大是第二

大城市 在周围人口稠密的埃及,

它在地理和

社会经济上都容易受到

海平面上升

2015 年发表的一篇研究论文发现

,海平面仅上升

半米就可能淹没其大部分

海滩

,如果没有有效的适应,可能会导致

大约 200 万人流离失所,

另外半米可能会使

超过 600

万人流离失所 正在上升,

预计到 2050

年,埃及海岸的水位将增加半米以上,

预计最终将上升到

一米多。

预计到 2060 年,埃及的

国家农业部门

可能会减少一半,因为

地下水被盐污染

导致区域粮食供应

和经济的潜在不稳定

无论我们是否回收食物,这些挑战都是

可持续

的,当我们住的时候关灯

房间仍在发生,

相反,我们需要大规模的结构

变化,为

社区做好准备 即将发生的事情并

降低未来的成本

但是海平面并不是 alexa 独有的

ndria

,它不是埃及独有的,它是一个

全球性威胁,

让我们缩小一下,看看

这个问题在全球范围内的影响 这张

地图显示了 2060 年

生活

海平面上升风险最高的地区的预计人口,这些地区被

称为低

海拔沿海地区或简称 lecz

目前这是全球 10%

的人口居住的地方

海平面上升,其相应的

影响非常复杂,

取决于环境政治

和社会经济因素,但

估计最终将有

8800 万到 14

亿人不等

由于海平面上升而流离失所,

因此洪水可能导致

数亿人

被迫在国内迁移,甚至在

国际上寻求庇护,

除了这将对受影响的社区造成明显威胁之外,

它还可能威胁我们的全球系统,

但是

还有许多其他的 气候

变化影响我们未来的方式

现在转向水资源短缺问题,

这是一个非常现实

和现实的问题,可能

由于气候变化的影响而加剧

让我们放大到南亚,这里是

世界上最严重的

水资源危机之一。

红色阴影越深

只有 20% 的巴基斯坦人口

能够获得安全饮用水

,其余 80% 的人口

被污水化肥农药

或工业废水洗劫一空,这种

污染是 麻省理工学院的研究人员在 2019 年的一份报告中发现,

在巴基斯坦全国范围内造成 30 人死亡的罪魁祸首

印度也面临着严重的

缺水问题,

该报告

发现

,在几乎是美国国土面积两倍的情况下,有 6 亿人

面临严重缺水甚至极度缺水的情况

认为,

随着全国用水需求预计将

水资源短缺并非南亚独有。

全球威胁

现在让我们放大看看这

对世界其他地区有何影响

上图显示了

看看飓风造成的破坏 卡特里娜飓风

展示了世界各地存在的环境种族主义

这里有两张地图,一张显示城市

每个地区的贫富差距

,用蓝色阴影表示,另一张

新奥尔良有种族隔离的历史

这种系统性的压迫

导致

气候变化影响的更高风险在

这里我们看到城市每个病房的死亡人数

与城市的人口构成惊人地一致,

表明穷人 社区和

有色人种社区

在这场灾难中受到的

打击最为严重

由于成本较高且通常

储蓄较少,从而

扩大了先前存在的财富

差距,这些相同的社区需要更长的时间才能恢复

现在一个主要问题出现了,

如果这些是风险并且我们知道

风险

为什么我们现在不采取行动为什么不 我们

进行了必要的改变

,为我们的未来做好准备,

我只想承认这一点

年轻人和老年人

都在日复一日地工作以建设

更美好的未来

解决气候变化等缓慢发展的危机的最大障碍

是人类倾向于

暂时忽视

我们忽视未来并优先考虑

现在

同样我们忽视 看到他们

的影响力较小

他们

作为学生坐得越远,我对

在到期前一个月分配的 30 页论文的压力要小得多,而不是

在停留前一天

这种系统性的拖延会给

我们一种

危险的感觉 然而,

如果不立即采取行动,

进一步的成本将会累积,

并可能达到无法克服的

程度,

因此我们需要重新构建

我们思考决策

的方式,而重新构建我们思维的一个好方法

是通过代际行动

和提升年轻人

在 我们的决策

像我这样的 Z 世代年轻人

我们将被迫考虑

未来 今天创造,

而过去的环保主义者

为子孙后代主张

这些世代现在

以今天的青年的形式出现,这就是为什么

青年组织的行动,

如未来零时星期五,

认为海洋社会灭绝叛乱

和许多其他

人对今天的行动如此不可或缺

危机

青年气候联盟已动员

数百万人组织起来支持

气候行动

抗议气候

变化对我们

这一代和后代的世界构成生存威胁,

这些示威

活动有助于重新构建关于

气候变化

的对话,例如我能够 出席

2019 年

联合国气候峰会的许多世界

领导人国家元首

甚至市政领导人都

出席

了会议,他们的言论令人欣慰,但

峰会之所以真正引人注目

,是因为格蕾塔·布隆伯格等青年

谴责民选代表

无所作为 活动家

顺便说一句,

多年来在此类活动中所做的事情给我们的领导人施加了压力,

迫使他们更认真地对待这场危机,

然而,每一次成功的环保

运动都是代际的,无论是

顾问、

资助者、共同组织者还是参与者,

即使是最受青年领导的运动也会

受益 通过

与所有年龄段的人合作,

这一重点不仅仅是叙述问题,

而是为未来的领导者腾出空间的行动问题。至关重要的是

,z 一代的成员

在决策桌上获得席位

并给予更多 现在

参与的机会

这并不意味着将所有

责任

和决定都交给年轻人 这意味着

建立代际联盟

以共同解决问题

今天我们只触及了

气候变化

的表面

受海平面上升影响的

10 亿人中,目前有 24 亿人受

海平面上升影响 由于

水资源短缺以及气候变化如何

不成比例地影响

有色人种社区和贫困社区,

但重要的是要记住

,我们所谈论的大部分

内容都不是一成不变的,我们不

知道气候变化将带来的全部程度,

但是我们 确实知道会有

成本,

而且我们知道,

无论我们今天讨论了什么,我们现在做出

决定将决定

明天挑战

的严重程度 真正一起解决这些问题,

但是我们不能使用

使我们陷入困境的相同古老方法,

我们需要为

年轻的声音和

受我们需要面对的这场危机最不利影响的人的声音腾出空间并赋予他们权力

摆在我们面前的巨大挑战

而不是回避我们正在

经历这个世界所见过的最可怕的紧急情况,

让我们开始行动吧 ng喜欢
