In 2019, Greta Thunberg's environmental work inspired a move of the Doomsday Clock. Now, it's made another frightening motion.

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

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

Her work has been highly influential.

Including a movement of the Doomsday Clock.

The teen sat outside the Swedish parliament 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 two years 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, droughts, 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, 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.

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.

It's been a busy couple of years for the teen.

She even received one extremely dubious honor ...

We're talking about the Doomsday Clock.

Set up in 1947, it was designed to track our inevitable move towards the end of the world. Cheery stuff.

But thanks to Thunberg's work, the Bulletin of the Atomic Scientists met up to decide where exactly we stood in 2019.

For 3 out of the past 4 years, the group has made the decision to move the hands closer to midnight.

And last year was no exception.

Because we were moved to just one hundred seconds away from midnight.

And the reason? Greta Thunberg.

"As far as the Bulletin and the Doomsday Clock are concerned, the world has entered into the realm of the two-minute warning, a period when danger is high and the margin for error low. The moment demands attention and new, creative responses."

"If decision-makers continue to fail to act—pretending that being inside two minutes is no more urgent than the preceding period—citizens around the world should rightfully echo the words of climate activist Greta Thunberg and ask: 'How dare you?'"

So certainly proof of Thunberg's impact. But probably not one she's particularly happy with.

And this year, the Bulletin of the Atomic Scientists met up again.

They actually met up via Zoom to discuss the fate of the Doomsday Clock.

And their decision?

To keep the clock at 100 seconds from the end.

"Coronavirus has revealed our vulnerabilities in ways that none have before, not even pandemic influenza and the anthrax attacks of 2001."

"The pandemic serves as a historic wake-up call, a vivid illustration that national governments and international organizations are unprepared to manage complex and dangerous challenges, like those of nuclear weapons and climate change."
