Climate Action Tracker The state of the climate crisis in 2021 TED

2021 is a crucial year in the fight
against climate change.

According to the Paris Agreement
timetable, this year,

governments must make key decisions
on updating their climate action plans.

Are we on track to meet the goal
of limiting global warming

to 1.5 degrees Celsius?

There is good news and bad news,
and the details matter,

so let’s explore the data.

Under the 2015 Paris Agreement,

all countries agreed to hold
the global average temperature increase

well below 2 degrees Celsius,

and to pursue efforts to limit it
to 1.5 degrees Celsius.

Scientists, including the IPCC,

tell us that to meet
this 1.5-degree warming limit,

global greenhouse gas emissions
need to be cut in half by 2030,

and carbon dioxide emissions
need to reach net zero by around 2050 –

an enormous but achievable challenge.

The information presented here
is from the Climate Action Tracker,

a project that monitors
national commitments and actions

and is current
as of the 1st of June, 2021.

The good news has to do
with 30 years from now.

Increasingly, governments are pledging
to reduce emissions to net zero

by the middle of the century,

which would be in line
with the Paris Agreement’s goals.

There are already 131 national governments
that have adopted net zero targets

or are discussing them.

Those targets would cover 73 percent

of current global
greenhouse gas emissions.

They include the European Union,
which has enshrined this goal into law,

the UK, South Africa, Japan, South Korea,

Canada, China and the United States,

as well as several small island nations.

However, the currently implemented
actions of all countries

will do little more than stop
an increase in future emissions.

That will put us on a trajectory

for an estimated warming
of 2.9 degrees Celsius by 2100,

and lead to catastrophic climate change.

Under the Paris Agreement,

countries have to put forward
formal, updated commitments

to achieve the global target.

In the last few months,

the EU, the US, China
and others have done so,

and we estimate
that their full implementation

could bring us on a path to the warming
of 2.4 degrees Celsius by 2100.

Already better, but still far from 1.5.

There is a more optimistic case.

Let’s assume all the commitments
and stated intentions become policies,

and are followed by actions,

including the net zero targets
under discussion

or not yet officially submitted
under the Paris Agreement.

This would put the world on a trajectory

to keep global warming
to 2 degrees Celsius by 2100.

Additional increases in ambition

could bring the 1.5-degree Celsius target,
theoretically, within reach.

But that’s in theory.

The actual short-term actions and plans
don’t yet match the long-term intentions,

and that’s the bad news.

No one will be surprised
by the fact that short-term actions,

which may determine electoral outcomes,

are more timid than long-term commitments

that will fall on future
governments to execute.

But it is the next nine years

that will determine if we can achieve
the target of net zero by mid-century.

The first milestone is 2030.

By then, emissions will need to be halved

for the world to be brought
onto a 1.5-degree Celsius pathway.

If we miss the 2030 milestone,

making up for it later will be
increasingly expensive or even impossible.

But with currently proposed actions,

even the targets
announced in recent months,

global emissions
would barely stabilize until 2030,

leaving an enormous gap.

It is not in the spirit
of the Paris Agreement

for countries to simply resubmit
the same target as five years prior,

or to offer different targets

that don’t actually lead
to lower emissions.

This is, unfortunately, the case so far

for Australia, Mexico, Russia,
Singapore, Switzerland and Vietnam.

South Korea and New Zealand
say they will come up with new targets

before the end of the year.

Perhaps the worst case is Brazil,

whose new stated target
would lead to emissions increasing

from its earlier promise.

These countries need to reconsider
their decisions.

And finally, there are still
dozens of countries

that have not made
a new announcement for 2030,

such as Indonesia and India,

though they do still have some time
before the COP26 Conference

to formalize their proposals.

So in summary, the picture
is more hopeful than ever,

if we look at the stated 2050 goals,

but the actual short-term
climate actions won’t get us there.

There is good news elsewhere.

We can sometimes be surprised

by the speed at which
an entire sector can flip.

For example, renewable energy
is the new normal

for new power production
capacity worldwide,

because it’s cheaper.

Many major automakers
are transitioning to electric cars,

and the financial sector
seems to have started the movement

out of investing in fossil fuels.

Also, the first countries have announced

they will stop extracting
fossil fuels entirely.

The world needs to find
that kind of serious, bold leadership

to bring us onto a safer path.

And keep in mind that if we don’t
reach 1.5 degrees Celsius,

then the next target isn’t two degrees,
but 1.6 degrees Celsius.

The impacts of global warming
already being felt

will hit in a nonlinear, exponential way.

So when it comes to climate change,

every year, every action
and every tenth of a degree matters.

2021年是应对气候变化的关键一年

根据《巴黎协定》
时间表,今年,

各国政府必须
就更新其气候行动计划做出关键决定。

我们是否有望
实现将全球变暖

限制在 1.5 摄氏度的目标?

有好消息也有坏消息
,细节很重要,

所以让我们来探索一下数据。

根据 2015 年《巴黎协定》,

所有国家同意
将全球平均气温上升幅度控制

在 2 摄氏度

以内,并努力将其限制
在 1.5 摄氏度以内。

包括 IPCC 在内的科学家

告诉我们,要
达到 1.5 度的升温极限,到 2030 年

全球温室气体排放量
需要减少一半,到 2050 年

左右二氧化碳排放量
需要达到净零——这

是一个巨大但可以实现的挑战 .

这里提供的信息
来自气候行动追踪器,这是

一个监测
国家承诺和行动的项目

,截至 2021 年 6 月 1 日是最新的

。好消息
与 30 年后有关。

各国政府越来越多地承诺
到本世纪中叶将排放量减少到净零

这将
符合《巴黎协定》的目标。

已经有 131 个国家
政府采用了净零目标

或正在讨论这些目标。

这些目标将涵盖

当前全球
温室气体排放量的 73%。

它们包括
已将这一目标写入法律的欧盟

、英国、南非、日本、韩国、

加拿大、中国和美国,

以及一些小岛国。

然而,所有国家目前实施的
行动

只会阻止
未来排放量的增加。

这将使我们走上

预计
到 2100 年升温 2.9 摄氏度的轨道,

并导致灾难性的气候变化。

根据《巴黎协定》,

各国必须提出
正式的、最新的承诺

以实现全球目标。

在过去的几个月里

,欧盟、美国、中国
和其他国家已经这样做了

,我们
估计它们的全面实施

可以使我们在
2100 年之前实现 2.4 摄氏度的升温。

已经更好,但距离 1.5 还很远 .

还有一个更乐观的情况。

让我们假设所有承诺
和声明的意图都变成了政策,

然后是行动,

包括
正在讨论

或尚未
根据《巴黎协定》正式提交的净零目标。

这将使世界走上

到 2100 年将全球变暖控制
在 2 摄氏度的轨道上。

雄心的进一步增加

可以使 1.5 摄氏度的目标
在理论上触手可及。

但这是理论上的。

实际的短期行动和
计划尚未与长期意图相匹配

,这是个坏消息。

没有人会惊讶
于这样一个事实,

即可能决定选举结果

的短期行动比将由未来政府执行的长期承诺更加胆小

但未来

九年将决定我们能否
在本世纪中叶实现净零排放目标。

第一个里程碑是 2030 年。

到那时,全球排放量需要

减半,才能
进入 1.5 摄氏度的轨道。

如果我们错过了 2030 年的里程碑,

那么以后弥补它的
成本将越来越高,甚至是不可能的。

但根据目前提出的行动,

即使是
最近几个月宣布的目标,

全球排放量
到 2030 年才会稳定下来,

留下巨大的差距。

各国简单地重新
提交与五年前相同的目标,

或提供

实际上
不会降低排放的不同目标,都不符合《巴黎协定》的精神。

不幸的是,到目前为止

,澳大利亚、墨西哥、俄罗斯、
新加坡、瑞士和越南的情况都是如此。

韩国和新西兰
表示,他们将

在今年年底之前提出新的目标。

也许最糟糕的情况是巴西,

其新的既定目标
将导致其排放量比

之前的承诺增加。

这些国家需要重新考虑
他们的决定。

最后,还有
数十个

国家尚未
发布 2030 年的新公告,

例如印度尼西亚和印度,

尽管它们
距离 COP26

大会正式提出建议还有一段时间。

因此,总而言之,

如果我们看看既定的 2050 年目标,情况比以往任何时候都更有希望,

但实际的短期
气候行动不会让我们实现目标。

其他地方也有好消息。

我们有时

会对整个扇区翻转的速度感到惊讶。

例如,可再生能源
是全球

新发电
能力的新常态,

因为它更便宜。

许多主要汽车制造商
正在向电动汽车转型

,金融业
似乎已经开始

摆脱对化石燃料的投资。

此外,首批国家已

宣布将完全停止开采
化石燃料。

世界需要找到
那种严肃、大胆的领导

才能把我们带上一条更安全的道路。

请记住,如果我们没有
达到 1.5 摄氏度,

那么下一个目标不是 2 摄氏度,
而是 1.6 摄氏度。 已经感受到

的全球变暖的

影响将以非线性、指数的方式受到影响。

因此,当谈到气候变化时,

每一年,每一个行动
和每十分之一度都很重要。
