Our home is burning.
0:03
Rapid climate change is destabilizing our world.
0:06
It seems our emissions will not fall quickly enough to avoid runaway warming
0:10
and we may soon hit tipping points
0:11
that will lead to the collapse of ecosystems
0:14
and our civilization.
0:16
While scientists, activists and much of the younger generation urge action,
0:20
it appears most politicians are not committed to do anything meaningful
0:24
while the fossil fuel industry still works actively against change.
0:29
It seems humanity can’t overcome its greed
0:31
and obsession with short term profit
0:33
and personal gain to save itself.
0:36
And so for many the future looks grim and hopeless.
0:41
Young people feel particularly anxious and depressed.
0:44
Instead of looking ahead to a lifetime of opportunity they wonder
0:47
if they will even have a future
0:49
or if they should bring kids into this world.
0:52
It’s an age of doom
0:53
and hopelessness and giving up seems the only sensible thing to do.
0:58
But that’s not true.
1:01
You are not doomed.
1:02
Humanity is not doomed.
1:13
Despite the seriousness of the situation,
1:15
for years positive trends have accumulated
1:18
and there is finally some good news
1:21
and a clear path towards our collective climate goals.
1:24
Welcome to our Ted talk,
1:25
please watch this video to the end – check out our detailed sources afterwards
1:29
to learn more.
1:31
Ok!
1:31
Let’s start with the scariest things.
1:35
Canceling the Apocalypse Some of the most widely shared stories about Climate Change are
1:41
that it is an existential threat – the end of human civilization
1:45
and maybe even our own extinction event.
1:48
And that it is basically unavoidable now.
1:50
But what does science actually say?
1:53
As of 2022 the global average temperature has risen 1.2 degrees celsius compared to
1:58
preindustrial times.
2:00
Limiting warming to 1.5 degrees was the most ambitious goal of the Paris agreement
2:05
but we are not likely to meet it.
2:07
Already with the warming we have today, hot places will get hotter,
2:11
wet places wetter and the risk and strength of extreme weather events increase significantly.
2:17
Warming beyond 2 degrees makes all of these extremes more extreme,
2:22
extreme weather events more common with more ecosystems under major pressure.
2:27
Some will not survive.
2:29
At 3 degrees significant parts of earth, especially in developing countries,
2:34
might become unable to feed their populations.
2:36
Heat waves will become a major global issue.
2:39
Large scale natural systems will break down.
2:42
The scale and frequency of hurricanes,
2:44
fires and droughts will further increase and cause trillions in damage.
2:49
Poor regions and subsistence farmers will be hit the hardest.
2:53
Hundreds of millions of people will need to leave their homes.
2:56
In the 4-8 degree range the apocalypse begins – the hothouse earth,
3:01
where things change so quickly,
3:03
that it may become unable to support our large human population
3:07
and billions may perish,
3:08
leaving the rest on a hostile alien planet.
3:12
A decade ago, for lack of action and perspective,
3:15
many scientists assumed a 4+ degree world was our future
3:18
and a lot of public communication focused on exactly this future path.
3:23
Luckily, it's much less likely
3:25
that this version of the apocalypse will come to pass.
3:29
If current climate policies stagnate,
3:31
we’re likely to end up with warming 3 °C by 2100.
3:36
Which is scary and tragic and far from acceptable.
3:40
But this is actually good news – how?
3:44
In the last decade,
3:45
we have seen enough progress
3:46
that most scientists now think
3:48
that we have likely avoided apocalyptic climate change.
3:51
Although substantial risk still remains,
3:54
we can pretty confidently say that humanity isn’t going anywhere.
3:58
Civilization might have to change, but it will endure.
4:02
Which begs the question:
4:04
What has changed over the last ten years and is this really good news?
4:09
## The Invisible Shift You probably know this story:
4:13
The last decade has been an immense failure for climate policies around the world.
4:17
Instead of passing comprehensive, binding bills that would meaningfully reduce emissions we mostly did:
4:23
nothing.
4:24
A lost decade with one negative record after another.
4:28
And this story is true
4:29
and it is one reason why
4:30
so many people are giving up.
4:32
But it is not the whole picture.
4:35
Despite the lack of climate policies
4:36
and ongoing lobbying and misinformation campaigns from the fossil fuel industries,
4:41
there was a lot of progress.
4:43
Let us go back 20 years to see why today is so different:
4:48
Between 2000 and 2010, greenhouse gas emissions had grown by 24%,
4:53
three times as much as the increase in the previous decade.
4:57
Subsidies for fossil fuels aimed at promoting economic growth,
5:01
caused a colossal increase in their consumption.
5:04
For emerging countries like China
5:06
and India coal was the cheapest fuel for growth
5:08
while rich countries showed little interest in changing their ways.
5:12
In 2010, many people expected these trends to continue.
5:15
Instead of decreasing fossil fuel use its consumption would rise.
5:20
The next decade turned out to be very different though.
5:23
First of all, coal burning in emerging countries like India has been slowed down
5:27
or leveled off,
5:29
like in China.
5:30
And it has plummeted in rich countries like the UK and US.
5:34
Since 2015 three-quarters of planned coal plants have been canceled
5:38
and 44 countries have committed to stop building them.
5:41
Ten years ago that would have seemed like wishful thinking,
5:44
but today we can say with confidence: Coal is dying.
5:48
It is just not competitive anymore.
5:50
Because technologies we thought would remain expensive matured rapidly instead.
5:56
Renewable electricity has shown explosive progress.
5:59
In a mere decade wind energy got three times cheaper.
6:03
Solar electricity is now ten times cheaper!
6:06
Cheaper than coal or any other fossil-fuel burning power plant,
6:10
despite the massive subsidies
6:11
and global infrastructure propping up fossil fuels. 25 times more solar
6:17
and nearly 5 times more wind electricity is produced today compared with ten years
6:22
ago,
6:22
which is of course not nearly enough.
6:25
One of the biggest obstacles is the variability of their power output.
6:29
Renewables need a lot of energy storage to be a reliable power source,
6:33
like expensive batteries.
6:35
Amazingly battery prices have decreased by 97% in the past 30 years,
6:40
60% in the last decade alone –
6:42
which will serve all kinds of green technology like electric cars.
6:46
You might say, well that’s great
6:48
but didn’t Kurzgesagt’s last climate video say
6:51
that while wind and solar are nice,
6:53
we need nothing less than a fundamental transition of our global industrial system?
6:58
Yes but luckily the shift goes beyond just the energy sector.
7:02
Throughout the economy people are working on improving current technology to lower emissions.
7:07
We’re rapidly replacing old incandescent light bulbs with LEDs
7:11
that are ten times more efficient.
7:14
In 2020 about 7 out of 10 new cars in Norway were electric
7:18
or hybrid – In 2021 it was already 8 out of 10.
7:23
And the list goes on,
7:24
from electric heating and better insulation to ships traveling at half speed to save
7:28
fuel.
7:30
Wherever you look you find scientists,
7:31
engineers and entrepreneurs trying to solve some aspect of climate change.
7:36
Enormous amounts of human ingenuity are being brought to bear on this problem with
7:40
more and more people deciding to prioritize preventing rapid climate change.
7:45
Solutions for low-carbon production of cement, electronics and steel,
7:50
and innovations like artificial meat and carbon capture are in the works.
7:54
The more of these technologies we deploy; the cheaper new and better technology gets.
7:59
The cheaper they get, the more people use them.
8:02
And so on.
8:03
We can see the impact already:
8:05
The domestic CO2 output of rich countries is falling without a major recession.
8:10
Since the year 2000, the EU as a whole shows a 21% decrease,
8:14
Italy 28%, the UK 35%, Denmark 43%.
8:20
But the best news may be
8:21
that emissions are no longer necessarily coupled with economic growth.
8:25
In the past this was an inconvenient truth – to get richer,
8:29
you had to emit more.
8:30
Which led to fierce arguments between developing
8:32
and developed countries about the fairness of reducing emissions
8:36
while their populations were still poor.
8:38
But in the last decade we have seen
8:39
that it IS possible to increase prosperity without increasing emissions.
8:43
Emissions in the Czech Republic dropped 13% while their GDP grew by 27%!
8:49
France reduced their CO2 emissions by 14% while increasing GDP by 15%!
8:56
Romania saw an 8% decrease and 35% growth!
9:01
And even the largest economy on earth - the USA - decreased emissions by
9:05
4% while growing their GDP by 26%!
9:09
Some of you may call this a numbers trick.
9:12
That rich countries are just exporting emissions to poorer nations by moving the dirty
9:16
parts of their economies like manufacturing.
9:18
But even when we account for all of our imported goods,
9:21
the numbers still look positive!
9:23
It’s no longer a matter of having to choose between prosperity
9:27
and the climate as it seemed to be a decade ago.
9:30
Developing countries will profit from
9:31
that because as rich countries pay for the expensive development of green technologies,
9:36
they can adopt them more cheaply.
9:38
They can skip most of the high emission phase
9:40
that today's rich countries went through.
9:43
We are at the point where not decarbonizing is a bad business decision.
9:48
And we haven’t even really talked about solutions like carbon capture.
9:52
In 2000 it didn't really exist.
9:55
In 2022 that technology does exist
9:57
and costs around $600 to remove one ton of CO2 from the atmosphere.
10:02
As investment pours in and the technology matures and begins to scale,
10:06
it is likely that these costs will plummet over the next few decades.
10:10
So everything's fine then?
10:13
Well let us not get carried away here - all of these processes are
10:15
great but not nearly fast enough.
10:18
We are still doing way too little and technology will not magically solve everything.
10:22
We need to use fewer resources and use them longer,
10:25
design consumer goods that are repairable and durable and decrease our energy requirements.
10:31
We need much better infrastructure, agriculture and cities.
10:35
It will still be hard work,
10:36
especially to get the right policies passed and enacted.
10:40
But for the first time ever,
10:41
there are a few trendlines pointing solidly in the right direction.
10:46
And now imagine –
10:47
If all of this was achieved without proper financial
10:49
and political support and despite fossil fuel lobbying – just think what humanity can
10:55
do when climate change finally gets the political attention
10:58
and funding it needs.
10:59
So is it ok to feel hopeful again?
11:02
The situation is still dire and serious,
11:04
so what is the point of focusing on this side of the story?
11:09
The Trap of Hopelessness Climate change can feel overwhelming
11:14
and make your future seem bleak.
11:16
The sadness and hopelessness
11:18
that many people feel is real
11:20
and very destructive because it causes apathy.
11:23
Apathy that is only serving the fossil fuel industry
11:26
that is still delaying change however it can.
11:29
In a sense they have weaponized hopelessness.
11:33
We are now in phase 4 in the public debate about rapid climate change
11:36
action:
11:37
Phase 1 was: Climate Change is not real.
11:41
Phase 2 was: Climate Change is real but not caused by humans.
11:45
Phase 3 was: Climate Change may be caused by humans
11:49
but it’s not that bad.
11:50
Phase 4 is: Climate Change is no longer avoidable.
11:54
We are doomed and it doesn’t matter what we do.
11:57
If we want the world to change,
11:59
we first need to believe that change is possible.
12:02
And we have an abundance of evidence that it is.
12:05
Changes to our industrial system are gaining momentum, technology gets better and cheaper,
12:10
climate change has become a key issue in most free elections.
12:13
As more and more younger people move into influential positions,
12:16
they prioritize climate change and work on new solutions.
12:20
In 2022 most governments not only acknowledge it
12:23
but set their own net zero goals – in democratic
12:27
and autocratic countries.
12:29
The results of years of fighting a steep uphill battle are now clearly visible.
12:34
The pressure needs to keep increasing,
12:36
to make sure that the promises made today are actually kept!
12:41
Climate doomerism is the equivalent of giving up even
12:44
though you can still prevent not just the worst case
12:46
but also mitigate most of the bad things,
12:49
make changes in time to adapt better and prevent the poorest from suffering.
12:53
That is why hopelessness and apathy are so dangerous.
12:58
If the last, in many ways wasted decade, has shown anything,
13:02
then it’s that progress is being made
13:04
and that dire scenarios are just predictions – not our sealed fate.
13:09
As of 2022, based on current global policies,
13:12
we will end up in a 3 degrees world.
13:16
Now it is our job to yet again prove the predictions wrong – despite
13:19
how serious and urgent things are.
13:21
To turn that 3 degrees into a 2 degrees
13:24
and then see where we can go from there.
13:26
For that we need hope.
13:29
And we hope we gave you that today, at least a little.
13:33
That you feel that things are serious but also that you have a future.
13:37
That you can have kids without dooming them or the world.
13:40
That taking action today is worth it.
13:43
And that despite powerful industries doing everything to delay it, society is changing.
13:49
If you need a more concrete roadmap of what you can do personally –
13:52
we are working on a follow up video to talk about
13:54
that in greater detail.
13:59
Doomerism, inactivity and weaponized hopelessness are the only trump cards left for the powers
14:03
that don’t want change.
14:05
Don’t let them win.
