Global warming speech for students: the climate change epic battle

Every epic story comes from a common point: an imbalance. That’s the first lesson we all need to learn about global warming.

When we look on the internet, we see people saying that the Earth has always had cycles of rising temperatures, followed by phases of cooling. They will say that this whole process is normal, even though we have the highest average temperature in the last 12,000 years. We are unbalanced.

Our lifestyle is all based on greenhouse gases. The burning of fossil fuels brings the fuel for our cars, the electricity for our smartphones, the lights in our homes and our medical devices. Our whole life revolves around this imbalance.

Meanwhile, arctic ice melts, sea levels rise, species become extinct and extreme events begin to appear with frequency: fires, hurricanes, tsunamis and droughts.

In every epic story there is a master to guide the way, bring ideas and restore balance. Our teachers are the scientists. They’ve already warned us: there are some scenarios in our future — and some of them are catastrophic.

The mission is simple, but not easy: to zero our carbon emissions. That means changing the way we do everything. In the last 200 years we’ve thrown more carbon into the atmosphere and destroyed forests, nature’s super power to recover.

Every epic story has a hero and a villain. Our destiny is not defined yet. It takes little time to have hope. Today, we are the villains of the story, but we can roll the dice one more time and turn the tide.

For this, each family, each nation, each company, each religion needs to be united for this cause. We have little time to find green alternatives and apply them on a global scale, but together we are faster, smarter and stronger.

Barack Obama global warming speech

If you prefer to read it instead, you can access Obama’s speech transciption below:

On Christmas Eve, 1968, the astronauts of Apollo 8 did a live broadcast from lunar orbit. So Frank Borman, Jim Lovell, William Anders — the first humans to orbit the moon -– described what they saw, and they read Scripture from the Book of Genesis to the rest of us back here. And later that night, they took a photo that would change the way we see and think about our world.

It was an image of Earth -– beautiful; breathtaking; a glowing marble of blue oceans, and green forests, and brown mountains brushed with white clouds, rising over the surface of the moon.

And while the sight of our planet from space might seem routine today, imagine what it looked like to those of us seeing our home, our planet, for the first time. Imagine what it looked like to children like me. Even the astronauts were amazed. “It makes you realize,” Lovell would say, “just what you have back there on Earth.”

And around the same time we began exploring space, scientists were studying changes taking place in the Earth’s atmosphere. Now, scientists had known since the 1800s that greenhouse gases like carbon dioxide trap heat, and that burning fossil fuels release those gases into the air. That wasn’t news. But in the late 1950s, the National Weather Service began measuring the levels of carbon dioxide in our atmosphere, with the worry that rising levels might someday disrupt the fragile balance that makes our planet so hospitable. And what they’ve found, year after year, is that the levels of carbon pollution in our atmosphere have increased dramatically.

That science, accumulated and reviewed over decades, tells us that our planet is changing in ways that will have profound impacts on all of humankind.

The 12 warmest years in recorded history have all come in the last 15 years. Last year, temperatures in some areas of the ocean reached record highs, and ice in the Arctic shrank to its smallest size on record — faster than most models had predicted it would. These are facts.

Now, we know that no single weather event is caused solely by climate change. Droughts and fires and floods, they go back to ancient times. But we also know that in a world that’s warmer than it used to be, all weather events are affected by a warming planet. The fact that sea level in New York, in New York Harbor, are now a foot higher than a century ago — that didn’t cause Hurricane Sandy, but it certainly contributed to the destruction that left large parts of our mightiest city dark and underwater.

The potential impacts go beyond rising sea levels. Here at home, 2012 was the warmest year in our history. Midwest farms were parched by the worst drought since the Dust Bowl, and then drenched by the wettest spring on record. Western wildfires scorched an area larger than the state of Maryland. Just last week, a heat wave in Alaska shot temperatures into the 90s.

And we know that the costs of these events can be measured in lost lives and lost livelihoods, lost homes, lost businesses, hundreds of billions of dollars in emergency services and disaster relief. In fact, those who are already feeling the effects of climate change don’t have time to deny it — they’re busy dealing with it. Firefighters are braving longer wildfire seasons, and states and federal governments have to figure out how to budget for that. I had to sit on a meeting with the Department of Interior and Agriculture and some of the rest of my team just to figure out how we’re going to pay for more and more expensive fire seasons.

Farmers see crops wilted one year, washed away the next; and the higher food prices get passed on to you, the American consumer. Mountain communities worry about what smaller snowpacks will mean for tourism — and then, families at the bottom of the mountains wonder what it will mean for their drinking water. Americans across the country are already paying the price of inaction in insurance premiums, state and local taxes, and the costs of rebuilding and disaster relief.

So the question is not whether we need to act. The overwhelming judgment of science — of chemistry and physics and millions of measurements — has put all that to rest. Ninety-seven percent of scientists, including, by the way, some who originally disputed the data, have now put that to rest. They’ve acknowledged the planet is warming and human activity is contributing to it.

So the question now is whether we will have the courage to act before it’s too late. And how we answer will have a profound impact on the world that we leave behind not just to you, but to your children and to your grandchildren.

As a President, as a father, and as an American, I’m here to say we need to act. 

I refuse to condemn your generation and future generations to a planet that’s beyond fixing. And that’s why, today, I’m announcing a new national climate action plan, and I’m here to enlist your generation’s help in keeping the United States of America a leader — a global leader — in the fight against climate change.

This plan builds on progress that we’ve already made. Last year, I took office — the year that I took office, my administration pledged to reduce America’s greenhouse gas emissions by about 17 percent from their 2005 levels by the end of this decade. And we rolled up our sleeves and we got to work. We doubled the electricity we generated from wind and the sun. We doubled the mileage our cars will get on a gallon of gas by the middle of the next decade.

Greta Thunberg’s speech on climate change

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 degrees, and the risk of setting off irreversible chain reactions beyond human control.

Fifty percent 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 degrees global temperature rise the world had 420 gigatons of CO2 left to emit back on Jan. 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 1/2 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.

Global warming: what the hell is happening to our planet?

Leonardo DiCaprio’s speech on global warming

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 that mankind has looked at climate change in that same way, as if it were fiction, as if pretending the climate change wasn’t real would somehow make it go away.
But I think we all know better than that now.

Every week we’re seeing new and undeniable climate events, evidence that accelerated climate change is here right now. Droughts are intensifying. Our oceans are acidifying with methane plumes rising up from the ocean floor.

We are seeing extreme weather events 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 knows it. 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 this difficult but achievable task. You can make history or you will 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 our governments around the world taking decisive large-scale action.

Now must be our moment for action.

We need to put a price tag on carbon emissions and eliminate government subsidies for all oil coal and gas companies. We need to end the free ride that industrial polluters have been given in the name of a free market economy. They do not 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.
This is not a partisan debate. It is a human one. Clean air and a livable climate are inalienable human rights. And solving this crisis is not a question of politics. It is a question of our own survival.

This is the most urgent of times and the most urgent of messages. Honored 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. But now it is your turn. The time to answer humankind’s greatest challenge is now.

We beg of you to face it with courage and honesty.

Thank you.

Arnold Schwarzenegger global warming speech

I have come to feel great affection for the peoples of the world because they’ve always been so welcoming to me — if it is as a bodybuilding champion, or as a movie star, private citizen, or as the governor of the great state of California.

And you, their delegates, have also made me feel very welcome here this morning. So I want to thank you for this great honor for having me here.

I also want to thank my wife and my partner and the First Lady of California, Maria Shriver, for being here today with me. Give her a big hand — right over there she is.

Now, I’ve been asked — I’ve been asked to talk to you today about what is happening in California. What are we doing about climate change? Well ladies and gentlemen, something remarkable is beginning to stir — something revolutionary, something historic and transformative. Let me give you some background.

California already leads the nation in information technology. We lead the nation in nanotechnology, in biotechnology, and in medical technology. We generate one of every four U.S. patents, and we attract almost half of all U.S. venture capital. And according to The Economist magazine, California is also home to three of the top six universities in the world. And in addition to all of this, California is the seventh largest economy in the world.
Now I do not mention these things to just simply boast or brag.

I’m mentioning it because California is a very powerful state, a very powerful place. And when do something, it has consequences. And here is what we are doing.

California is mobilizing — technologically, financially, and politically — to fight global climate change. Now we’re not doing this alone. While California is leading in the U.S., we are building on the work of the European countries who have led the way up until now and have done extraordinary work. England has already met its Kyoto goals. Germany has pioneered solar. The EU has led with its trading system. And the list goes on and on.

But California, because of its unique position, is on the cutting edge of what is to come. And what is coming will benefit the countries and peoples represented in this chamber. Last year in California, we enacted greenhouse gas emission standards that were beyond anyone else’s dreams. We enacted the world’s first low carbon fuel standards.

Now do I believe that California’s standards will solve global warming? Of course not. What we’re doing is is changing the dynamic, preparing the way and encouraging the future. The aerospace industry built the modern economy of Southern California. The computer industry and the internet built the economy of the Silicon Valley. And now green, clean technology — along with biotech — will take California to the next level.

Right now, in California, the brightest scientists from around the world and the smartest venture capitalists are racing to find new energy technologies and the solution to global warming. It is a race that is fueled by billions and billions of dollars. Last year alone, California received more than 1.1 billion dollars in clean tech investment.

And this amount is expected to grow by 20 to 30% annually for the next ten years. More venture capital is being invested in clean tech than in telecommunications. Now I have been to those labs and research parks. I have talked with the scientists and to the venture capitalists. I have seen their ambition. And let me tell you, I would not bet against it.

So what does all this mean for the nations in this chamber? Well the cell phone, which started as a tool for the rich, is now widespread in the developing world. The price has dropped dramatically, and therefore it can be afforded by almost everyone. And the same thing will happen with environmental technologies. And it is in the developed world’s best interests to help the poor nations finance these advancements.

Thank you very much. Thank you.
