Looking to be inspired to take action on climate change? Watch these four powerful climate change speeches, and get ready to change the world.

Climate change is the most pressing concern facing us and our planet. As such, we need powerful action, and fast, from both global leaders and global corporations, right down to individuals.

I’ve got over 70 climate change and sustainability quotes to motivate people and inspire climate action. But if it is more than quotes you need then watch these four impassioned climate change speeches. These speeches are particularly good if you are looking for even more inspiration to inspire others to take climate action.

Greta Thunberg’s Climate Change Speech at the 2019 UN Climate Action Summit

In September 2019 climate activist Greta Thunberg addressed the U.N.’s Climate Action Summit in New York City with this inspiring climate change speech:

Transcript

Here’s the full transcript of Greta Thunberg’s climate change speech. It begins with Greta’s response to a question about the message she has for world leaders.

My message is that we’ll be watching you.

This is all wrong. I shouldn’t be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you!

You have stolen my dreams and my childhood with your empty words. And yet I’m one of the lucky ones. People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic growth. How dare you!

For more than 30 years, the science has been crystal clear. How dare you continue to look away and come here saying that you’re doing enough when the politics and solutions needed are still nowhere in sight.

You say you hear us and that you understand the urgency. But no matter how sad and angry I am, I do not want to believe that. Because if you really understood the situation and still kept on failing to act, then you would be evil. And that I refuse to believe.

The popular idea of cutting our emissions in half in 10 years only gives us a 50% chance of staying below 1.5°C, and the risk of setting off irreversible chain reactions beyond human control.

Fifty per cent may be acceptable to you. But those numbers do not include tipping points, most feedback loops, additional warming hidden by toxic air pollution or the aspects of equity and climate justice. They also rely on my generation sucking hundreds of billions of tons of your CO₂ out of the air with technologies that barely exist.

So a 50% risk is simply not acceptable to us — we who have to live with the consequences.

To have a 67% chance of staying below a 1.5°C global temperature rise – the best odds given by the Intergovernmental Panel on Climate Change – the world had 420 gigatons of CO₂ left to emit back on January 1st, 2018. Today that figure is already down to less than 350 gigatons.

How dare you pretend that this can be solved with just ‘business as usual’ and some technical solutions? With today’s emissions levels, that remaining CO₂ budget will be entirely gone within less than 8 and a half years.

There will not be any solutions or plans presented in line with these figures here today, because these numbers are too uncomfortable. And you are still not mature enough to tell it like it is.

You are failing us. But the young people are starting to understand your betrayal. The eyes of all future generations are upon you. And if you choose to fail us, I say: We will never forgive you.

We will not let you get away with this. Right here, right now is where we draw the line. The world is waking up. And change is coming, whether you like it or not.

Thank you.

Leonardo DiCaprio’s Climate Change Speech at the 2014 UN Climate Summit

Leonardo DiCaprio gave an impassioned climate change speech at the 2014 UN Climate Summit. Watch it now:

Transcript

Here’s a transcript of Leonardo DiCaprio’s climate change speech in case you’re looking to quote any part of it.

Thank you, Mr Secretary General, your excellencies, ladies and gentleman, and distinguished guests. I’m honoured to be here today, I stand before you not as an expert but as a concerned citizen. One of the 400,000 people who marched in the streets of New York on Sunday, and the billions of others around the world who want to solve our climate crisis.

As an actor, I pretend for a living. I play fictitious characters often solving fictitious problems.

I believe humankind has looked at climate change in that same way. As if it were fiction, happening to someone else’s planet, as if pretending that climate change wasn’t real would somehow make it go away.

But I think we know better than that. Every week, we’re seeing new and undeniable climate events, evidence that accelerated climate change is here now. We know that droughts are intensifying.  Our oceans are warming and acidifying, with methane plumes rising up from beneath the ocean floor. We are seeing extreme weather events, increased temperatures, and the West Antarctic and Greenland ice sheets melting at unprecedented rates, decades ahead of scientific projections.

None of this is rhetoric, and none of it is hysteria. It is fact. The scientific community knows it. Industry and governments know it. Even the United States military knows it. The chief of the US Navy’s Pacific Command, Admiral Samuel Locklear, recently said that climate change is our single greatest security threat.

My friends, this body – perhaps more than any other gathering in human history – now faces that difficult task. You can make history or be vilified by it.

To be clear, this is not about just telling people to change their light bulbs or to buy a hybrid car. This disaster has grown BEYOND the choices that individuals make. This is now about our industries, and governments around the world taking decisive, large-scale action.

I am not a scientist, but I don’t need to be. Because the world’s scientific community has spoken, and they have given us our prognosis. If we do not act together, we will surely perish.

Now is our moment for action.

We need to put a price tag on carbon emissions and eliminate government subsidies for coal, gas, and oil companies. We need to end the free ride that industrial polluters have been given in the name of a free-market economy. They don’t deserve our tax dollars, they deserve our scrutiny. For the economy itself will die if our ecosystems collapse.

The good news is that renewable energy is not only achievable but good economic policy. New research shows that by 2050 clean, renewable energy could supply 100% of the world’s energy needs using existing technologies, and it would create millions of jobs.

This is not a partisan debate; it is a human one. Clean air and water, and a livable climate are inalienable human rights. And solving this crisis is not a question of politics. It is our moral obligation – if, admittedly, a daunting one.

We only get one planet. Humankind must become accountable on a massive scale for the wanton destruction of our collective home. Protecting our future on this planet depends on the conscious evolution of our species.

This is the most urgent of times, and the most urgent of messages.

Honoured delegates, leaders of the world, I pretend for a living. But you do not. The people made their voices heard on Sunday around the world and the momentum will not stop. And now it’s YOUR turn, the time to answer the greatest challenge of our existence on this planet is now.

I beg you to face it with courage. And honesty. Thank you.

Yeb Sano’s Climate Change Speech at the United Nations Climate Summit in Warsaw

The Philippines’ lead negotiator Yeb Sano addressed the opening session of the UN climate summit in Warsaw in November 2013. In this emotional and powerful climate change speech he called for urgent action to prevent a repeat of the devastating storm that hit parts of the Philippines:

Transcript of Yeb’s Climate Change Speech

Here’s a transcript of Yeb’s climate change speech:

Mr President, I have the honour to speak on behalf of the resilient people of the Republic of the Philippines.

At the onset, allow me to fully associate my delegation with the statement made by the distinguished Ambassador of the Republic of Fiji, on behalf of G77 and China as well as the statement made by Nicaragua on behalf of the Like-Minded Developing Countries.

First and foremost, the people of the Philippines, and our delegation here for the United Nations Climate Change Convention’s 19^th Conference of the Parties here in Warsaw, from the bottom of our hearts, thank you for your expression of sympathy to my country in the face of this national difficulty.

In the midst of this tragedy, the delegation of the Philippines is comforted by the warm hospitality of Poland, with your people offering us warm smiles everywhere we go. Hotel staff and people on the streets, volunteers and personnel within the National Stadium have warmly offered us kind words of sympathy. So, thank you Poland.

The arrangements you have made for this COP is also most excellent and we highly appreciate the tremendous effort you have put into the preparations for this important gathering.

We also thank all of you, friends and colleagues in this hall and from all corners of the world as you stand beside us in this difficult time.

I thank all countries and governments who have extended your solidarity and for offering assistance to the Philippines.

I thank the youth present here and the billions of young people around the world who stand steadfastly behind my delegation and who are watching us shape their future.

I thank civil society, both who are working on the ground as we race against time in the hardest-hit areas, and those who are here in Warsaw prodding us to have a sense of urgency and ambition.

We are deeply moved by this manifestation of human solidarity. This outpouring of support proves to us that as a human race, we can unite; that as a species, we care.

It was barely 11 months ago in Doha when my delegation appealed to the world… to open our eyes to the stark reality that we face… as then we confronted a catastrophic storm that resulted in the costliest disaster in Philippine history.

Less than a year hence, we cannot imagine that a disaster much bigger would come. With an apparent cruel twist of fate, my country is being tested by this hellstorm called Super Typhoon Haiyan, which has been described by experts as the strongest typhoon that has ever made landfall in the course of recorded human history.

It was so strong that if there was a Category 6, it would have fallen squarely in that box. Up to this hour, we remain uncertain as to the full extent of the devastation, as information trickles in an agonisingly slow manner because electricity lines and communication lines have been cut off and may take a while before these are restored.

The initial assessment shows that Haiyan left a wake of massive devastation that is unprecedented, unthinkable, and horrific, affecting 2/3 of the Philippines, with about half a million people now rendered homeless, and with scenes reminiscent of the aftermath of a tsunami, with a vast wasteland of mud and debris and dead bodies.

According to satellite estimates, the US National Oceanic and Atmospheric Administration also estimated that Haiyan achieved a minimum pressure between around 860 mbar (hPa; 25.34 inHg) and the Joint Typhoon Warning Center estimated Haiyan to have attained one-minute sustained winds of 315 km/h (195 mph) and gusts up to 378 km/h (235 mph) making it the strongest typhoon in modern recorded history.

Despite the massive efforts that my country had exerted in preparing for the onslaught of this monster of a storm, it was just a force too powerful, and even as a nation familiar with storms, Super Typhoon Haiyan was nothing we have ever experienced before, or perhaps nothing that any country has every experienced before.

The picture in the aftermath is ever so slowly coming into clearer focus. The devastation is colossal. And as if this is not enough, another storm is brewing again in the warm waters of the western Pacific. I shudder at the thought of another typhoon hitting the same places where people have not yet even managed to begin standing up.

To anyone who continues to deny the reality that is climate change, I dare you to get off your ivory tower and away from the comfort of your armchair.

I dare you to go to the islands of the Pacific, the islands of the Caribbean and the islands of the Indian Ocean and see the impacts of rising sea levels; to the mountainous regions of the Himalayas and the Andes to see communities confronting glacial floods, to the Arctic where communities grapple with the fast dwindling polar ice caps, to the large deltas of the Mekong, the Ganges, the Amazon, and the Nile where lives and livelihoods are drowned, to the hills of Central America that confront similar monstrous hurricanes, to the vast savannahs of Africa where climate change has likewise become a matter of life and death as food and water becomes scarce.

Not to forget the massive hurricanes in the Gulf of Mexico and the eastern seaboard of North America. And if that is not enough, you may want to pay a visit to the Philippines right now.

The science has given us a picture that has become much more in focus. The IPCC report on climate change and extreme events underscored the risks associated with changes in the patterns as well as the frequency of extreme weather events.

Science tells us that simply, climate change will mean more intense tropical storms. As the Earth warms up, that would include the oceans. The energy that is stored in the waters off the Philippines will increase the intensity of typhoons and the trend we now see is that more destructive storms will be the new norm.

This will have profound implications on many of our communities, especially who struggle against the twin challenges of the development crisis and the climate change crisis. Typhoons such as Yolanda (Haiyan) and its impacts represent a sobering reminder to the international community that we cannot afford to procrastinate on climate action. Warsaw must deliver on enhancing ambition and should muster the political will to address climate change.

In Doha, we asked, “If not us then who? If not now, then when? If not here, then where?” (borrowed from Philippine student leader Ditto Sarmiento during Martial Law). It may have fell on deaf ears. But here in Warsaw, we may very well ask these same forthright questions. “If not us, then who? If not now, then when? If not here in Warsaw, where?”

What my country is going through as a result of this extreme climate event is madness. The climate crisis is madness.

We can stop this madness. Right here in Warsaw.

It is the 19^th COP, but we might as well stop counting because my country refuses to accept that a COP30 or a COP40 will be needed to solve climate change.

And because it seems that despite the significant gains we have had since the UNFCCC was born, 20 years hence we continue to fail in fulfilling the ultimate objective of the Convention. 

Now, we find ourselves in a situation where we have to ask ourselves – can we ever attain the objective set out in Article 2 – which is to prevent dangerous anthropogenic interference with the climate system? By failing to meet the objective of the Convention, we may have ratified the doom of vulnerable countries.

And if we have failed to meet the objective of the Convention, we have to confront the issue of loss and damage.

Loss and damage from climate change is a reality today across the world. Developed country emissions reduction targets are dangerously low and must be raised immediately. But even if they were in line with the demand of reducing 40-50% below 1990 levels, we would still have locked-in climate change and would still need to address the issue of loss and damage.

We find ourselves at a critical juncture and the situation is such that even the most ambitious emissions reductions by developed countries, who should have been taking the lead in combatting climate change in the past two decades, will not be enough to avert the crisis.

It is now too late, too late to talk about the world being able to rely on Annex I countries to solve the climate crisis. We have entered a new era that demands global solidarity in order to fight climate change and ensure that the pursuit of sustainable human development remains at the fore of the global community’s efforts. This is why means of implementation for developing countries is ever more crucial.

It was the Secretary-general of the UN Conference on Environment and Development, Earth Summit, Rio de Janeiro, 1992, Maurice Strong who said that “History reminds us that what is not possible today, may be inevitable tomorrow.”

We cannot sit and stay helpless staring at this international climate stalemate. It is now time to take action. We need an emergency climate pathway.

I speak for my delegation. But more than that, I speak for the countless people who will no longer be able to speak for themselves after perishing from the storm. I also speak for those who have been orphaned by this tragedy. I also speak for the people now racing against time to save survivors and alleviate the suffering of the people affected by the disaster.

We can take drastic action now to ensure that we prevent a future where super typhoons are a way of life. Because we refuse, as a nation, to accept a future where super typhoons like Haiyan become a fact of life. We refuse to accept that running away from storms, evacuating our families, suffering the devastation and misery, having to count our dead, become a way of life. We simply refuse to.

We must stop calling events like these as natural disasters. It is not natural when people continue to struggle to eradicate poverty and pursue development and get battered by the onslaught of a monster storm now considered as the strongest storm ever to hit land. It is not natural when science already tells us that global warming will induce more intense storms. It is not natural when the human species has already profoundly changed the climate.

Disasters are never natural. They are the intersection of factors other than physical. They are the accumulation of the constant breach of economic, social, and environmental thresholds.

Most of the time disasters are a result of inequity and the poorest people of the world are at greatest risk because of their vulnerability and decades of maldevelopment, which I must assert is connected to the kind of pursuit of economic growth that dominates the world. The same kind of pursuit of so-called economic growth and unsustainable consumption that has altered the climate system.

Now, if you will allow me, to speak on a more personal note.

Super Typhoon Haiyan made landfall in my family’s hometown and the devastation is staggering. I struggle to find words even for the images that we see from the news coverage. I struggle to find words to describe how I feel about the losses and damages we have suffered from this cataclysm.

Up to this hour, I agonize while waiting for word as to the fate of my very own relatives. What gives me renewed strength and great relief was when my brother succeeded in communicating with us that he has survived the onslaught. In the last two days, he has been gathering bodies of the dead with his own two hands. He is hungry and weary as food supplies find it difficult to arrive in the hardest-hit areas.

We call on this COP to pursue work until the most meaningful outcome is in sight. Until concrete pledges have been made to ensure mobilisation of resources for the Green Climate Fund. Until the promise of the establishment of a loss and damage mechanism has been fulfilled. Until there is assurance on finance for adaptation. Until concrete pathways for reaching the committed 100 billion dollars have been made. Until we see real ambition on stabilizing greenhouse gas concentrations. We must put the money where our mouths are.

This process under the UNFCCC has been called many names. It has been called a farce. It has been called an annual carbon-intensive gathering of useless frequent flyers. It has been called many names. But it has also been called “The Project To Save The Planet”. It has been called “Saving Tomorrow Today”. We can fix this. We can stop this madness. Right now. Right here, in the middle of this football field.

I call on you to lead us. And let Poland be forever known as the place we truly cared to stop this madness. Can humanity rise to the occasion? I still believe we can.

Greta Thunberg’s Speech at Houses of Parliament

Finally, in April 2019, Greta spoke at the Houses of Parliament in the UK. Here she gave this powerful climate change speech to the UK’s political leaders:

Transcript of Greta’s Climate Change Speech

Here is the full transcript of Greta’s climate change speech:

My name is Greta Thunberg. I am 16 years old. I come from Sweden. And I speak on behalf of future generations.

I know many of you don’t want to listen to us – you say we are just children. But we’re only repeating the message of the united climate science.

Many of you appear concerned that we are wasting valuable lesson time, but I assure you we will go back to school the moment you start listening to science and give us a future. Is that really too much to ask?

In the year 2030, I will be 26 years old. My little sister Beata will be 23. Just like many of your own children or grandchildren. That is a great age, we have been told. When you have all of your life ahead of you. But I am not so sure it will be that great for us.

I was fortunate to be born in a time and place where everyone told us to dream big. I could become whatever I wanted to. I could live wherever I wanted to. People like me had everything we needed and more. Things our grandparents could not even dream of. We had everything we could ever wish for and yet now we may have nothing.

Now we probably don’t even have a future anymore.

Because that future was sold so that a small number of people could make unimaginable amounts of money. It was stolen from us every time you said that the sky was the limit and that you only live once.

You lied to us. You gave us false hope. You told us that the future was something to look forward to. And the saddest thing is that most children are not even aware of the fate that awaits us. We will not understand it until it’s too late. And yet we are the lucky ones. Those who will be affected the hardest are already suffering the consequences. But their voices are not heard.

Is my microphone on? Can you hear me?

Around the year 2030, 10 years 252 days and 10 hours away from now, we will be in a position where we set off an irreversible chain reaction beyond human control, that will most likely lead to the end of our civilisation as we know it. That is unless, in that time, permanent and unprecedented changes in all aspects of society have taken place, including a reduction of CO₂ emissions by at least 50%.

And please note that these calculations are depending on inventions that have not yet been invented at scale, inventions that are supposed to clear the atmosphere of astronomical amounts of carbon dioxide.

Furthermore, these calculations do not include unforeseen tipping points and feedback loops like the extremely powerful methane gas escaping from rapidly thawing arctic permafrost.

Nor do these scientific calculations include already locked-in warming hidden by toxic air pollution. Nor the aspect of equity – or climate justice – clearly stated throughout the Paris Agreement, which is absolutely necessary to make it work on a global scale.

We must also bear in mind that these are just calculations. Estimations. That means that these “points of no return” may occur a bit sooner or later than 2030. No one can know for sure. We can, however, be certain that they will occur approximately in these timeframes because these calculations are not opinions or wild guesses.

These projections are backed up by scientific facts, concluded by all nations through the IPCC. Nearly every single major national scientific body around the world unreservedly supports the work and findings of the IPCC.

Did you hear what I just said? Is my English OK? Is the microphone on? Because I’m beginning to wonder.

During the last six months, I have travelled around Europe for hundreds of hours in trains, electric cars, and buses, repeating these life-changing words over and over again. But no one seems to be talking about it, and nothing has changed. In fact, the emissions are still rising.

When I have been travelling around to speak in different countries, I am always offered help to write about the specific climate policies in specific countries. But that is not really necessary. Because the basic problem is the same everywhere. And the basic problem is that basically nothing is being done to halt – or even slow – climate and ecological breakdown, despite all the beautiful words and promises.

The UK is, however, very special. Not only for its mind-blowing historical carbon debt but also for its current, very creative, carbon accounting.

Since 1990 the UK has achieved a 37% reduction of its territorial CO₂ emissions, according to the Global Carbon Project. And that does sound very impressive. But these numbers do not include emissions from aviation, shipping, and those associated with imports and exports. If these numbers are included the reduction is around 10% since 1990 – or an average of 0.4% a year, according to Tyndall Manchester.

And the main reason for this reduction is not a consequence of climate policies, but rather a 2001 EU directive on air quality that essentially forced the UK to close down its very old and extremely dirty coal power plants and replace them with less dirty gas power stations. And switching from one disastrous energy source to a slightly less disastrous one will of course result in a lowering of emissions.

But perhaps the most dangerous misconception about the climate crisis is that we have to “lower” our emissions. Because that is far from enough.

Our emissions have to stop if we are to stay below 1.5-2°C of warming. The “lowering of emissions” is of course necessary but it is only the beginning of a fast process that must lead to a stop within a couple of decades or less. And by “stop” I mean net-zero – and then quickly on to negative figures. That rules out most of today’s politics.

The fact that we are speaking of “lowering” instead of “stopping” emissions is perhaps the greatest force behind the continuing business as usual. The UK’s active current support of new exploitation of fossil fuels – for example, the UK shale gas fracking industry, the expansion of its North Sea oil and gas fields, the expansion of airports as well as the planning permission for a brand new coal mine – is beyond absurd.

This ongoing irresponsible behaviour will no doubt be remembered in history as one of the greatest failures of humankind.

People always tell me and the other millions of school strikers that we should be proud of ourselves for what we have accomplished. But the only thing that we need to look at is the emission curve. And I’m sorry, but it’s still rising. That curve is the only thing we should look at.

Every time we make a decision we should ask ourselves; how will this decision affect that curve? We should no longer measure our wealth and success in the graph that shows economic growth, but in the curve that shows the emissions of greenhouse gases. We should no longer only ask: “Have we got enough money to go through with this?” but also: “Have we got enough of the carbon budget to spare to go through with this?” That should and must become the centre of our new currency.

Many people say that we don’t have any solutions to the climate crisis. And they are right. Because how could we? How do you “solve” the greatest crisis that humanity has ever faced? How do you “solve” a war? How do you “solve” going to the moon for the first time? How do you “solve” inventing new inventions?

The climate crisis is both the easiest and the hardest issue we have ever faced. The easiest because we know what we must do. We must stop the emissions of greenhouse gases. The hardest because our current economics are still totally dependent on burning fossil fuels, and thereby destroying ecosystems in order to create everlasting economic growth.

“So, exactly how do we solve that?” you ask us – the schoolchildren striking for the climate.

And we say: “No one knows for sure. But we have to stop burning fossil fuels and restore nature and many other things that we may not have quite figured out yet.”

Then you say: “That’s not an answer!”

So we say: “We have to start treating the crisis like a crisis – and act even if we don’t have all the solutions.”

“That’s still not an answer,” you say.

Then we start talking about circular economy and rewilding nature and the need for a just transition. Then you don’t understand what we are talking about.

We say that all those solutions needed are not known to anyone and therefore we must unite behind the science and find them together along the way. But you do not listen to that. Because those answers are for solving a crisis that most of you don’t even fully understand. Or don’t want to understand.

You don’t listen to the science because you are only interested in solutions that will enable you to carry on like before. Like now. And those answers don’t exist anymore. Because you did not act in time.

Avoiding climate breakdown will require cathedral thinking. We must lay the foundation while we may not know exactly how to build the ceiling.

Sometimes we just simply have to find a way. The moment we decide to fulfil something, we can do anything. And I’m sure that the moment we start behaving as if we were in an emergency, we can avoid climate and ecological catastrophe. Humans are very adaptable: we can still fix this. But the opportunity to do so will not last for long. We must start today. We have no more excuses.

We children are not sacrificing our education and our childhood for you to tell us what you consider is politically possible in the society that you have created. We have not taken to the streets for you to take selfies with us, and tell us that you really admire what we do.

We children are doing this to wake the adults up. We children are doing this for you to put your differences aside and start acting as you would in a crisis. We children are doing this because we want our hopes and dreams back.

I hope my microphone was on. I hope you could all hear me.
