It's been a pretty busy year for climate change activist, Greta Thunberg.

The teen bagged the 2019 Right Livelihood Award, which is widely known as the "Alternative Nobel Prize," for her pioneering work in the youth climate change movement, scooping up a pretty impressive cash prize and just this week, TIME Magazine honored Thunberg with their most prestigious title.

Now Thunberg has pledged that 2020 must be a year of action, and that she will put 'world leaders against the wall' if they do not tackle climate change.

Keep scrolling to find out exactly what she said...

Greta Thunberg has become the face of the youth climate change movement.

The Swedish sixteen-year-old has been responsible for the global school strike movement, which began with weekly Friday school strikes to protest for climate change action.

Just a year ago, she was relatively unknown.

Greta would regularly sit on her own outside Swedish parliament, first staging a "School Strike for Climate" in August last year. In the weeks leading up to the country’s general election, Thunberg sat on the steps outside of the parliament building in Stockholm, holding up the now-iconic sign that read “Skolstrejk För Klimatet" — translating to “school strike for climate."

The teen sat outside the building during school hours for 3 weeks.

Her demands were that the Swedish government reduce carbon emissions in accordance with the Paris Agreement. By sacrificing her education to protest for action, the teen began to conjure up attention and gain traction online.

Her unwavering commitment to the environment has woken the rest of the world.

While a little over a year ago, the name "Greta Thunberg" was relatively unknown, now, her's is the first name that springs to mind when you think of the climate change movement.

Thunberg is known for delivering blistering, matter-of-fact speeches about the urgency of what she calls the "climate crisis."

If we fast-forward to now, Thunberg continues to hold governments accountable during her powerful talks, which have seen her nominated for a Nobel Peace Prize and placed in TIME's top one-hundred influential people in the world list.

Her message is clear: we need to act now.

Having whipped up a gigantic global youth movement, climate change is finally getting the attention it deserves, but Thunberg still believes that governments are the ones who still aren't listening. According to the United Nations, humanity has under twelve years to prevent a climate change crisis. A report released by the Intergovernmental Panel on Climate Change (IPCC) at the end of 2018 called for immediate “unprecedented changes" to all aspects of society.

If we do not act, the future, if there is one at all, will be very bleak.

Rising global temperatures pose a high risk of social and environmental disasters, including floods, drought, wildfires, and food shortages for millions of people across our planet.

Thunberg has gone to great lengths to fight her cause.

In July, the teen ditched environmentally damaging air travel and sailed across the Atlantic to attend the U.N. climate summits in the U.S. and Chile.

Little by little, her trailblazing activism seems to be sinking in.

According to Live Kindly, earlier this year, Mohammed Barkindo — the secretary-general of OPEC (the Organization of the Petroleum Exporting Countries) — acknowledged public opinion surrounding the climate crisis as a threat to the oil industry.

And her youth school strike movement is growing on a mass scale.

On September 20, millions around the world, from London to New York, Sydney to Colombia, ditched the classroom to peacefully protest for climate action in what Thunberg dubs "Fridays for Future."

But, Thunberg's movement has been met with waves of criticism.

Her activism has seen her labeled "melodramatic" amongst other things, as well as others saying that she is being used as a political shield.

But her critics don't phase her...

Thunberg addressed world leaders at the U.N. Climate Summit and delivered a blistering, anger-tinged speech demanding climate action.

The event is dedicated to world leaders sharing climate solutions and new pledges for climate action.

During her powerful speech, Thunberg highlighted how the science behind climate change has been "crystal clear" for over 3 decades. "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!" she said. "You have stolen my dreams and my childhood with your empty words."

As she spoke, the teen got visibly emotional.

"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!" She continued: "How dare you continue to look away and come here saying that you are 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 don’t want to believe that. Because if you fully understood the situation and still kept on failing to act, then you would be evil. And I refuse to believe that."

She concluded with a poignant message: change is coming, whether you like it or not.

"You are failing us. But 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."

After her speech, the teen activist happened to cross paths with Donald Trump in the lobby.

Safe to say, she understandably isn't his biggest fan and shot him the most intense death stare we've ever seen.

The video went viral online.

When faced with one of the world's most powerful leaders, Thunberg remained fearless, and her death stare has become something of an internet sensation.

As you'd expect, Donald Trump had something to say about the whole thing.

In usual Trump-style, he took to Twitter to seemingly mock the teen, writing, "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!" above a video of her speech.

His swipe radiated sarcasm.

And of course, people slammed the president for attacking the young activist.

It's been a busy year for the teen.

Thunberg was even listed as 1 of 4 winners of the 2019 Right Livelihood Award, which is widely known as the "Alternative Nobel Prize."

Thunberg was honored with the prize for her "inspiring" work.

According to a statement from the Right Livelihood Foundation, "Thunberg is the powerful voice of a young generation that will have to bear the consequences of today's political failure to stop climate change."
"Her resolve to not put up with the looming climate disaster has inspired millions of peers to also raise their voices and demand immediate climate action."

Thunberg joined 3 other winners who bagged the award too.

Brazilian indigenous leader, Davi Kopenawa of the Yanomami people, Chinese women’s rights lawyer, Guo Jianmei, and Western Sahara human rights defender, Aminatou Haidar also share the award with the teen.

Thunberg, along with the other winners, scooped up a pretty impressive cash prize.

According to Reuters, the 4 winners will each receive a cash award of one million Swedish krona ($103,000).

Here's how Thunberg reacted to her win...

The climate change activist said she "shared the award with the many people and adults who have joined her in her environmental crusade." "I'm deeply grateful for being one of the recipients of this great honor."

Although she was quick to say that she isn't the sole winner.

"But of course, whenever I receive an award, it is not me who is the winner. I am part of a global movement of school children, youth and adults of all ages who have decided to act in defense of our living planet. I share this award with them," she added." "The Right Livelihood Award is a huge recognition for Fridays For Future and the climate strike movement. Thank you so very much!" It was an impressive win.

Soon after, it was announced Thunberg's award season wasn't over.

She was awarded a coveted Environmental Prize from the Nordic Council, which comes with a whopping $400,o00 cash prize.

But Thunberg had a rather unexpected reaction.

While expressing gratitude for being chosen, she's also decided to turn down the award - and she took to social media to explain why.

Thunberg declined the award in a lengthy Instagram post.

"I have received the Nordic Council’s environmental award 2019. I have decided to decline this prize."

"Here’s why."

"The climate movement does not need any more awards. What we need is for our politicians and the people in power start to listen to the current, best available science."

"The Nordic countries have a great reputation around the world when it comes to climate and environmental issues."

"There is no lack of bragging about this. There is no lack of beautiful words. But when it comes to our actual emissions and our ecological footprints per capita - if we include our consumption, our imports as well as aviation and shipping - then it’s a whole other story."

"In Sweden, we live as if we had about 4 planets according to WWF and Global Footprint Network."

"And roughly the same goes for the entire Nordic region. In Norway for instance, the government recently gave a record number of permits to look for new oil and gas. The newly opened oil and natural gas-field, "Johan Sverdrup" is expected to produce oil and natural gas for 50 years; oil and gas that would generate global CO2 emissions of 1,3 tonnes."

"The gap between what the science says is needed to limit the increase of global temperature rise to below 1,5 or even 2 degrees - and politics that run the Nordic countries is gigantic."

"And there are still no signs whatsoever of the changes required."

"The Paris Agreement, which all of the Nordic countries have signed, is based on the aspect of equity, which means that richer countries must lead the way."

"We belong to the countries that have the possibility to do the most. And yet our countries still basically do nothing. So until you start to act in accordance with what the science says is needed to limit the global temperature rise below 1.5 degrees or even 2 degrees celsius, I - and Fridays For Future in Sweden - choose not to accept the Nordic Councils environmental award nor the prize money of 500, 000 Swedish krona."

"Best wishes, Greta Thunberg."

It's a bold move - but she has declined with grace. She wrote, "I want to thank the Nordic Council for this award. It is a huge honor."

Here's the full post.

And then Thunberg became the recipient of another prestigious title.

Because Thunberg has been awarded the title of TIME's Person of the Year.

Impressive in itself - but Thunberg also marks the youngest person ever to receive this title.

She beat out some fierce competition.

Thunberg was honored over other nominees including Speaker of the House Nancy Pelosi, the CIA whistleblower who triggered Trump's impeachment proceedings, and Hong Kong's pro-democracy protesters.

"She became the biggest voice on the biggest issue facing the planet this year, coming from essentially nowhere to lead a worldwide movement."

"She embodies youth activism. Her rise in influence has been really extraordinary. She was a solo protester with a hand-painted sign 14 months ago. She's now led millions of people around the world, 150 countries, to act on behalf of the planet, and she's really been a key driver this year taking this issue from backstage to center," said TIME's Editor-in-Chief Edward Felsenthal.

Thunberg wasn't the only one honored.

Alongside Person of the Year, TIME launched four new categories to celebrate other important figures from 2019, including the US women's soccer team and Lizzo.

"[Thunberg] also represents a broader generational shift in the culture that we're seeing from the campuses of Hong Kong to the protests in Chile to Parkland, Florida, where the students marched against gun violence, where young people are demanding change urgently."

A stellar end to a stellar year for the inspirational teen.

Now she has vowed to take things further.

Attending a rally in Turin, Italy, the 16-year-old activist vowed that 2020 had to be a year of action for climate change activism. Greta had previously been in Madrid at the UN Climate Summit, however speaking afterwards she claimed she was worried the event would lead to no real change.

She said she will put leaders against the wall.

Speaking about her disappointment with many world leaders, Greta claimed she would put many world leaders up against the wall next year, according to the Daily Mail. More specifically she said:
Unfortunately, we probably already know the outcome. World leaders are still trying to run away from their responsibilities but we have to make sure they cannot do that. We will make sure that we put them against the wall and they will have to do their job to protect our futures.

The crowd went wild.

The massive crowd in Italy went crazy for the Swedish activist, taking on board everything she said. She also spoke about her disappointment in the older generations for doing so little about the climate. She said:
It is not fair that the older generation are handing over the responsibility to solve this crisis to us young people who have not started this crisis. It's not fair that we have to do all this.

She also explained:

The adults are behaving as if there is no tomorrow but there is a tomorrow, it is the tomorrow where our young people will live and we have to fight for that tomorrow. We can no longer take that tomorrow for granted. What we decide to do or not to do in this decade we will have to live with for the rest of our lives.

'The next decade will define our future'.

Greta concluded that 'the next decade will define our future', adding that our children and grandchildren are the ones that will have to deal with it. Good luck Greta. It certainly sounds like 2020 is going to be an interesting year for the rebellion revolution.
