5 Apr 202214:11

Summary

TLDR视频剧本深入探讨了气候变化的严峻现实及其对人类文明的潜在威胁。尽管目前全球平均气温已较工业化前水平上升了1.2摄氏度,且我们可能无法实现巴黎协定中限制升温1.5度的雄心目标,但过去十年的积极进展表明,我们有可能避免灾难性的气候变化。可再生能源成本的大幅下降、电池价格的降低以及全球工业系统的转型,都为应对气候变化提供了希望。剧本呼吁人们保持希望,积极参与到减缓气候变化的行动中,共同推动社会向更可持续的方向发展。

Takeaways

  • 🌍 我们的家园正在燃烧,气候变化正在破坏我们的世界。
  • 🔥 我们的排放量可能无法迅速降低,以避免不可控制的变暖,我们可能很快就会达到导致生态系统和我们文明崩溃的临界点。
  • 👨‍🔬 尽管科学家、活动家和年轻一代敦促采取行动,但大多数政治家似乎并未致力于采取有意义的措施,化石燃料行业仍在积极反对变革。
  • 💔 人类似乎无法克服其贪婪和对短期利润和个人利益的迷恋,以拯救自己。
  • 👶 年轻人感到特别焦虑和沮丧,他们不再期待一生的机遇,而是怀疑他们是否还有未来,或者是否应该将孩子带入这个世界。
  • 🌑 这是一个充满绝望和无望的时代,放弃似乎是唯一明智的选择。
  • 🚫 但这并不真实。你并非注定要失败。人类并非注定要失败。
  • 📉 尽管情况严重,多年来积极的趋势已经积累,现在终于有一些好消息和明确的路径,朝着我们的集体气候目标前进。
  • 🌡️ 截至2022年,全球平均气温比前工业时代上升了1.2摄氏度,限制升温到1.5度是巴黎协定中最具雄心的目标,但我们不太可能实现它。
  • 🛑 即使在当前的变暖水平下,热的地方会变得更热,湿的地方会更湿,极端天气事件的风险和强度显著增加。
  • 🌳 2度以上的升温会使所有极端情况更加极端,极端天气事件更常见,对生态系统造成更大的压力。一些生态系统可能无法存活。
  • 📉 3度的升温可能使地球上的部分地区,特别是发展中国家,无法养活自己的人口。热浪将成为全球性问题,大规模自然系统将崩溃。
  • 🌐 4-8度范围内,地球将变成一个“温室地球”,变化如此之快,以至于可能无法支持我们庞大的人类人口,数十亿人可能会死亡,剩下的人将生活在一个敌对的外星星球上。
  • ⬇️ 幸运的是,这种版本的世界末日现在不太可能发生,如果当前的气候政策停滞不前,我们可能会在2100年达到3°C的升温。
  • 🔄 过去十年,我们看到足够的进步,以至于大多数科学家现在认为我们已经可能避免了灾难性的气候变化。虽然仍有相当大的风险,但我们可以相当有信心地说,人类不会消失。
  • 🚫 尽管缺乏气候政策和化石燃料行业的持续游说和误导信息,但仍取得了很多进展。
  • 📉 2000年至2010年间,温室气体排放量增长了24%,是前一个十年增长的三倍。化石燃料补贴导致其消费量大幅增加。
  • 🌿 自2015年以来,四分之三的计划中的燃煤电厂被取消,44个国家承诺停止建设它们。煤炭不再具有竞争力。
  • 💨 我们认为会保持昂贵的技术迅速成熟。可再生电力显示出爆炸性的进展。在过去的十年中,风能成本降低了三倍,太阳能电力现在是原来的十分之一。
  • 🔋 电池价格在过去30年中下降了97%,仅在过去十年中就下降了60%,这将服务于所有类型的绿色技术,如电动汽车。
  • 🌱 经济中的人们正在努力改进现有技术以降低排放。我们正在迅速用LED灯泡替换旧的白炽灯泡,LED灯泡的效率是原来的十倍。
  • 🚗 2020年,挪威约70%的新车是电动或混合动力车——到2021年,这一数字已经是80%。
  • 💡 从电热、更好的绝缘到减慢船只速度以节省燃料,无论你在哪里看,都会发现科学家、工程师和企业家正在尝试解决气候变化的某个方面。
  • 📉 富裕国家的国内二氧化碳排放量在没有重大衰退的情况下正在下降。自2000年以来,欧盟整体减少了21%,意大利减少了28%,英国减少了35%,丹麦减少了43%。
  • 🌱 但最好的消息可能是,排放量不再必然与经济增长挂钩。在过去,这是一个不便的事实——要变得更富有,你必须排放更多。
  • 💼 发展中国家将从中受益,因为富裕国家为绿色技术的昂贵发展付费,他们可以更便宜地采用这些技术。他们可以跳过今天富裕国家经历的大部分高排放阶段。
  • 🛠️ 不再脱碳是一个糟糕的商业决策。
  • 🌿 我们甚至还没有真正谈论像碳捕获这样的解决方案。在2000年,它几乎不存在。到2022年,这项技术确实存在,并且每吨二氧化碳从大气中移除的成本约为600美元。
  • 🌐 那么一切都好了吗?嗯,我们不要过于兴奋——所有这些过程都很棒,但速度远远不够。我们仍然做得太少,技术不会神奇地解决一切问题。
  • 🏛️ 我们需要使用更少的资源,更长时间地使用它们,设计可修复和耐用的消费品,降低我们的能源需求。我们需要更好的基础设施、农业和城市。
  • 📉 尽管如此,我们仍然需要努力工作,特别是要通过和实施正确的政策。
  • 📈 但有史以来第一次,有一些趋势线明确指向正确的方向。
  • 🌟 现在想象一下——如果所有这些在没有适当的财政和政治支持的情况下实现,尽管化石燃料游说——想想当气候变化最终获得它需要的政治关注和资金时,人类可以做什么。
  • 🌱 那么,我们可以再次感到有希望吗?情况仍然严峻和严重,那么关注这个故事的这一面有什么意义呢?
  • 😔 气候变化可能会让人感到不知所措,让你的未来看起来暗淡。许多人感到的悲伤和绝望是真实的,也是非常具有破坏性的,因为它会导致冷漠。
  • 💣 冷漠只会服务于仍在尽可能拖延变革的化石燃料行业。从某种意义上说,他们已经将绝望武器化了。
  • 🌐 我们现在正处于关于迅速采取气候变化行动的公共辩论的第四阶段:
  • 📉 第一阶段是:气候变化不是真的。
  • 📉 第二阶段是:气候变化是真实的,但不是人为造成的。
  • 📉 第三阶段是:气候变化可能是由人类造成的,但没那么糟糕。
  • 📉 第四阶段是:气候变化不再可以避免。我们注定要失败,我们做什么都无所谓。
  • 🌱 如果我们想让世界改变,我们首先需要相信改变是可能的。我们有大量证据表明这是可能的。
  • 🌐 我们的工业系统正在获得动力,技术变得更好、更便宜,气候变化已成为大多数自由选举的关键问题。
  • 👶 随着越来越多的年轻人进入有影响力的职位,他们优先考虑气候变化并致力于新的解决方案。
  • 🌐 2022年,大多数政府不仅承认了这一点,还设定了自己的净零目标——在民主和独裁国家。
  • 🛑 多年来艰苦奋斗的结果现在清晰可见。需要不断增加压力,以确保今天做出的承诺真正得到兑现!
  • 💔 气候末日论是放弃的等价物,即使你仍然可以防止不仅仅是最坏的情况,还可以减轻大部分坏事,及时做出更好的适应变化,并防止最贫穷的人受苦。这就是为什么绝望和冷漠如此危险。
  • 📉 如果说在许多方面被浪费的过去十年有什么启示,那就是正在取得进展,严峻的情景只是预测——不是我们注定的命运。
  • 🌐 截至2022年,根据当前的全球政策,我们将进入一个3度的世界。
  • 🚀 现在,我们的工作是再次证明预测是错误的——尽管情况多么严重和紧迫。将3度变成2度,然后看看我们能从那里走到哪里。
  • 🌟 为此,我们需要希望。我们希望我们今天至少给了你一点希望。让你感到事情是严重的,但也让你有未来。你可以生孩子,而不会毁了他们或世界。今天采取行动是值得的。
  • 🌱 尽管强大的行业尽一切努力拖延它,但社会正在改变。如果你需要一个更具体的个人行动路线图——我们正在制作一个后续视频,以更详细地讨论这个问题。
  • 💔 末日论、不活动和武器化的绝望是不希望变革的力量所剩下的唯一王牌。不要让他们赢。

Our home is burning. Rapid climate  change is destabilizing our world.  

play00:06

It seems our emissions will not fall quickly  enough to avoid runaway warming and we may  

play00:10

soon hit tipping points that will lead to the  collapse of ecosystems and our civilization.

play00:16

While scientists, activists and much  of the younger generation urge action,  

play00:20

it appears most politicians are not  committed to do anything meaningful  

play00:24

while the fossil fuel industry still works  actively against change. It seems humanity  

play00:30

can’t overcome its greed and obsession with short  term profit and personal gain to save itself.

play00:36

And so for many the future looks grim and  hopeless. Young people feel particularly  

play00:42

anxious and depressed. Instead of looking  ahead to a lifetime of opportunity they  

play00:47

wonder if they will even have a future or  if they should bring kids into this world.  

play00:52

It’s an age of doom and hopelessness and  giving up seems the only sensible thing to do.

play00:58

But that’s not true. You are not  doomed. Humanity is not doomed.  

play01:13

Despite the seriousness of the situation, for  years positive trends have accumulated and there  

play01:19

is finally some good news and a clear path towards  our collective climate goals. Welcome to our Ted  

play01:25

talk, please watch this video to the end – check  out our detailed sources afterwards to learn more.

play01:31

Ok! Let’s start with the scariest things.

play01:35

Canceling the Apocalypse

play01:38

Some of the most widely shared stories about  Climate Change are that it is an existential  

play01:43

threat – the end of human civilization and  maybe even our own extinction event. And  

play01:48

that it is basically unavoidable now.  But what does science actually say?

play01:53

As of 2022 the global average temperature  

play01:55

has risen 1.2 degrees celsius  compared to preindustrial times.  

play02:00

Limiting warming to 1.5 degrees was the  most ambitious goal of the Paris agreement  

play02:04

but we are not likely to meet it. Already with the  warming we have today, hot places will get hotter,  

play02:11

wet places wetter and the risk and strength of  extreme weather events increase significantly.

play02:17

Warming beyond 2 degrees makes all of these  extremes more extreme, extreme weather events  

play02:23

more common with more ecosystems under  major pressure. Some will not survive.

play02:29

At 3 degrees significant parts of earth,  especially in developing countries,  

play02:33

might become unable to feed their populations.  Heat waves will become a major global issue.  

play02:39

Large scale natural systems will break  down. The scale and frequency of hurricanes,  

play02:44

fires and droughts will further increase and cause  trillions in damage. Poor regions and subsistence  

play02:50

farmers will be hit the hardest. Hundreds of  millions of people will need to leave their homes.

play02:56

In the 4-8 degree range the apocalypse begins  – the hothouse earth, where things change  

play03:02

so quickly, that it may become unable  to support our large human population  

play03:06

and billions may perish, leaving  the rest on a hostile alien planet.  

play03:12

A decade ago, for lack of action and perspective,  many scientists assumed a 4+ degree world was our  

play03:18

future and a lot of public communication  focused on exactly this future path.  

play03:23

Luckily, it's much less likely that this  version of the apocalypse will come to pass.

play03:29

If current climate policies stagnate, we’re  likely to end up with warming 3 °C by 2100.  

play03:36

Which is scary and tragic and far from acceptable.  But this is actually good news – how? In the last  

play03:44

decade, we have seen enough progress that most  scientists now think that we have likely avoided  

play03:49

apocalyptic climate change. Although substantial  risk still remains, we can pretty confidently say  

play03:55

that humanity isn’t going anywhere. Civilization  might have to change, but it will endure.

play04:02

Which begs the question: What has changed over  the last ten years and is this really good news?

play04:08

## The Invisible Shift

play04:11

You probably know this story: The  last decade has been an immense  

play04:15

failure for climate policies around the world.  

play04:17

Instead of passing comprehensive, binding  bills that would meaningfully reduce emissions  

play04:22

we mostly did: nothing. A lost decade with one  negative record after another. And this story  

play04:28

is true and it is one reason why so many people  are giving up. But it is not the whole picture.

play04:34

Despite the lack of climate policies and ongoing  

play04:37

lobbying and misinformation campaigns  from the fossil fuel industries,  

play04:41

there was a lot of progress. Let us go back  20 years to see why today is so different:

play04:48

Between 2000 and 2010, greenhouse  gas emissions had grown by 24%,  

play04:53

three times as much as the increase in the  previous decade. Subsidies for fossil fuels  

play04:59

aimed at promoting economic growth, caused  a colossal increase in their consumption.  

play05:04

For emerging countries like China and  India coal was the cheapest fuel for growth  

play05:08

while rich countries showed little  interest in changing their ways.

play05:12

In 2010, many people expected these trends  to continue. Instead of decreasing fossil  

play05:17

fuel use its consumption would rise. The next  decade turned out to be very different though.

play05:23

First of all, coal burning in emerging countries  like India has been slowed down or leveled off,  

play05:28

like in China. And it has plummeted  in rich countries like the UK and US.  

play05:34

Since 2015 three-quarters of planned coal  plants have been canceled and 44 countries  

play05:39

have committed to stop building them. Ten years  ago that would have seemed like wishful thinking,  

play05:44

but today we can say with confidence: Coal  is dying. It is just not competitive anymore.  

play05:50

Because technologies we thought would remain  expensive matured rapidly instead. Renewable  

play05:56

electricity has shown explosive progress. In a  mere decade wind energy got three times cheaper.  

play06:03

Solar electricity is now ten times cheaper!  Cheaper than coal or any other fossil-fuel burning  

play06:09

power plant, despite the massive subsidies and  global infrastructure propping up fossil fuels.

play06:15

25 times more solar and nearly 5 times more wind  electricity is produced today compared with ten  

play06:21

years ago, which is of course not nearly enough.  One of the biggest obstacles is the variability  

play06:27

of their power output. Renewables need a lot of  energy storage to be a reliable power source,  

play06:32

like expensive batteries. Amazingly battery  prices have decreased by 97% in the past 30 years,  

play06:40

60% in the last decade alone – which will serve  all kinds of green technology like electric cars.

play06:46

You might say, well that’s great but  didn’t Kurzgesagt’s last climate video  

play06:51

say that while wind and solar are nice, we need  nothing less than a fundamental transition of  

play06:55

our global industrial system? Yes but luckily  the shift goes beyond just the energy sector.  

play07:02

Throughout the economy people are working on  improving current technology to lower emissions.

play07:07

We’re rapidly replacing old incandescent light  bulbs with LEDs that are ten times more efficient.  

play07:13

In 2020 about 7 out of 10 new  cars in Norway were electric  

play07:18

or hybrid – In 2021 it was already  8 out of 10. And the list goes on,  

play07:24

from electric heating and better insulation  to ships traveling at half speed to save fuel.

play07:29

Wherever you look you find scientists,  

play07:31

engineers and entrepreneurs trying to  solve some aspect of climate change.  

play07:36

Enormous amounts of human ingenuity are  being brought to bear on this problem  

play07:40

with more and more people deciding to prioritize  preventing rapid climate change. Solutions for  

play07:46

low-carbon production of cement, electronics and  steel, and innovations like artificial meat and  

play07:52

carbon capture are in the works. The more of  these technologies we deploy; the cheaper new  

play07:57

and better technology gets. The cheaper they  get, the more people use them. And so on.

play08:03

We can see the impact already:  

play08:05

The domestic CO2 output of rich countries  is falling without a major recession.  

play08:10

Since the year 2000, the EU as a whole shows a  21% decrease, Italy 28%, the UK 35%, Denmark 43%.

play08:19

But the best news may be that emissions are no  longer necessarily coupled with economic growth.  

play08:25

In the past this was an inconvenient truth  – to get richer, you had to emit more. Which  

play08:30

led to fierce arguments between developing  and developed countries about the fairness  

play08:34

of reducing emissions while their populations  were still poor. But in the last decade we have  

play08:39

seen that it IS possible to increase prosperity  without increasing emissions. Emissions in the  

play08:44

Czech Republic dropped 13% while their GDP grew  by 27%! France reduced their CO2 emissions by 14%  

play08:53

while increasing GDP by 15%! Romania saw  an 8% decrease and 35% growth! And even the  

play09:01

largest economy on earth - the USA - decreased  emissions by 4% while growing their GDP by 26%!

play09:09

Some of you may call this a numbers trick. That  rich countries are just exporting emissions to  

play09:14

poorer nations by moving the dirty parts of  their economies like manufacturing. But even  

play09:19

when we account for all of our imported goods,  the numbers still look positive! It’s no longer  

play09:24

a matter of having to choose between prosperity  and the climate as it seemed to be a decade ago.

play09:30

Developing countries will profit from  that because as rich countries pay for  

play09:34

the expensive development of green technologies,  they can adopt them more cheaply. They can skip  

play09:39

most of the high emission phase that  today's rich countries went through.  

play09:42

We are at the point where not  decarbonizing is a bad business decision.

play09:48

And we haven’t even really talked  about solutions like carbon capture.  

play09:52

In 2000 it didn't really exist. In 2022 that  technology does exist and costs around $600 to  

play09:59

remove one ton of CO2 from the atmosphere. As  investment pours in and the technology matures  

play10:05

and begins to scale, it is likely that these  costs will plummet over the next few decades.

play10:10

So everything's fine then? Well let us not get  carried away here - all of these processes are  

play10:15

great but not nearly fast enough. We are still  doing way too little and technology will not  

play10:21

magically solve everything. We need to use  fewer resources and use them longer, design  

play10:26

consumer goods that are repairable and durable  and decrease our energy requirements. We need  

play10:31

much better infrastructure, agriculture  and cities. It will still be hard work,  

play10:36

especially to get the right  policies passed and enacted.

play10:40

But for the first time ever,  

play10:41

there are a few trendlines pointing  solidly in the right direction.

play10:45

And now imagine – If all of this was achieved  without proper financial and political support  

play10:51

and despite fossil fuel lobbying  – just think what humanity can do  

play10:55

when climate change finally gets the  political attention and funding it needs.

play10:59

So is it ok to feel hopeful again? The  situation is still dire and serious,  

play11:04

so what is the point of focusing  on this side of the story?

play11:09

The Trap of Hopelessness

play11:12

Climate change can feel overwhelming and  make your future seem bleak. The sadness  

play11:17

and hopelessness that many people feel is real  and very destructive because it causes apathy.

play11:23

Apathy that is only serving the fossil  fuel industry that is still delaying  

play11:27

change however it can. In a sense  they have weaponized hopelessness.  

play11:32

We are now in phase 4 in the public  debate about rapid climate change action:

play11:37

Phase 1 was: Climate Change is not real.

play11:41

Phase 2 was: Climate Change is  real but not caused by humans.

play11:45

Phase 3 was: Climate Change may be  caused by humans but it’s not that bad.

play11:50

Phase 4 is: Climate Change is no longer avoidable.  We are doomed and it doesn’t matter what we do.

play11:57

If we want the world to change, we first need  to believe that change is possible. And we have  

play12:02

an abundance of evidence that it is. Changes  to our industrial system are gaining momentum,  

play12:08

technology gets better and cheaper, climate change  has become a key issue in most free elections.  

play12:13

As more and more younger people  move into influential positions,  

play12:16

they prioritize climate change and work on  new solutions. In 2022 most governments not  

play12:22

only acknowledge it but set their own net zero  goals – in democratic and autocratic countries.  

play12:29

The results of years of fighting a steep  uphill battle are now clearly visible. The  

play12:34

pressure needs to keep increasing, to make sure  that the promises made today are actually kept!

play12:41

Climate doomerism is the equivalent of giving up  even though you can still prevent not just the  

play12:45

worst case but also mitigate most of the bad  things, make changes in time to adapt better  

play12:51

and prevent the poorest from suffering. That is  why hopelessness and apathy are so dangerous.

play12:58

If the last, in many ways wasted  decade, has shown anything,  

play13:01

then it’s that progress is being made and that  dire scenarios are just predictions – not our  

play13:08

sealed fate. As of 2022, based on current global  policies, we will end up in a 3 degrees world.  

play13:15

Now it is our job to yet again prove the  predictions wrong – despite how serious and  

play13:20

urgent things are. To turn that 3 degrees into a  2 degrees and then see where we can go from there.

play13:26

For that we need hope. And we hope we gave you  that today, at least a little. That you feel  

play13:33

that things are serious but also that you have  a future. That you can have kids without dooming  

play13:38

them or the world. That taking action today is  worth it. And that despite powerful industries  

play13:45

doing everything to delay it, society is changing.  If you need a more concrete roadmap of what you  

play13:51

can do personally – we are working on a follow  up video to talk about that in greater detail.

play13:56

Doomerism, inactivity and weaponized hopelessness  

play14:00

are the only trump cards left for the powers  that don’t want change. Don’t let them win.
