"How dare you!" are the poignant words of pioneering climate change activist, Greta Thunberg, who addressed world leaders at the U.N. Climate Summit on Monday. Her powerful, stinging speech brought home the reality of the sheer ignorance of our world leaders when it comes to climate change, and their inability to do anything about it, or even see it as an issue in the first place.

However as is often the case with the Internet, things move quickly. And no longer are the eyes of the world on the UN speech, but they are on this.

A seemingly innocent photo of Greta went viral recently after trolls began slamming her for reportedly using single use plastics. To make matters worse, the same photo was then doctored and edited to show Greta eating in front of hungry looking children.

And thousands of people believed the image was legitimate... Including some big names in politics. Oh dear.

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 labelled "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...

Yesterday, 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 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."

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 has gone viral online.

When faced with one of the world's most powerful leaders, Thunberg remains fearless, and her death stare has become a somewhat 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.

Greta's speech wasn't the only thing to go viral this week.

A photo of the sixteen-year-old sat on the train was posted to Twitter by @pocket_rocket96.

This picture wasn't just any old picture though...

It showed Thunberg surrounded by lots of food and packaging while she eats.

Now, this may look like the ideal picture to shout "hypocrite!" at...

And that's exactly what this user did. She captioned the post: "Oh she looks so frightened about the immediate climate catastrophe. As she sits there on a train, surrounded by plastic containers and processed foods. A picture paints a thousand words. This tells you she knows nothing about what she speaks of."

But she made a very rookie mistake...

What @pocket_rocket96 failed to realize is that she wasn't enlightening anyone, just spreading false information. I mean, anyone can post on Twitter, even the misinformed.

Here's why she should have done the research.

Do you really think Greta Thunberg wouldn't practice what she preaches? And secondly, do you think someone who is close with her would post a potentially incriminating photograph of her? Some of these people really aren't the smartest tools in the box, are they?

Here are some facts for you:

Thankfully, @georgiaanais_ is here to set the haters straight.

She then continues...

I don't understand why some of you need reminding about this? I'm genuinely alarmed and disgusted at some "adults" in the world. I have to use that term very loosely because they're filled with habits that even children have grown out of.

Exhibit A: we have Andy over here.

Andy also forgot to do his research, a common feature among haters, so he posted this comment: "You can tell all that from one picture?" Oh Andy, you absolute idiot.

Thankfully, Georgia was back to enlighten him...

And it didn't stop there.

Someone else decided to hop in and set Andy and the rest of the haters straight.

So everything on the table in the photo is made from recyclable packaging? Wow. Gee. Who would have thought?! Finally, a leader that practices what she preaches.

However, things went from bad to worse.

As if being slandered by trolls for her apparent "use of plastics" wasn't bad enough, other trolls went to the extreme of doctoring the image of her on a train.

The "fake" photo caused outrage.

The edited photo showed Greta eating her lunch as several starving children looked inwards at the food. Although the image is quite clearly not authentic, many were convinced by the photo - including some high profile celebrities.

The President of Brazil's son shared the image.

One man who fell for the image was none other than the President of Brazil's son, Eduardo Bolsonaro. Bolsonaro, son of the controversial president, Jay Bolsonaro, shared the image with the caption: "'You stole my childhood' said the girl financed by George Soros' Open Society."

Eduardo also suggested that she receives funding from billionaires.

The post included an article that Eduardo shared which suggested that Thunberg receives funding from Hungarian-American billionaire, George Soros. However numerous reports state that there is no evidence at all to prove that Thunberg receives funding from Soros' foundation. In a position of power, sharing evidently fake information like this about "a CHILD" is unbelievably dangerous.

The president's son has now been accused of irresponsible fake news.

And it isn't only me who believes posts such as these to be despicable. Brazilian Senator, Eliziane Gama, slammed the post as a "great irresponsibility." She added: "Fake news today is an evil which must be combated in every democratic society in the world. It's something that we do not accept, and it is accepted even less when it is done by a public representative. Even less when it is a public representative who is being proposed to work in one of the most important embassies in the world. "It's irresponsibility, in my understanding, without precedent. It's lamentable, and I think the deputy needs to retract it, make an apology to the 16-year-old and to both the Brazilian and international society." I second that... but Bolsonaro doesn't seem to care.
