She's the voice of a global movement who mobilised millions of young people to demand action against climate change. Yet Greta Thunberg's message to the US Congress - a hotbed of climate scepticism - was:
“I don’t want you to listen to me. I want you to listen to the scientists."
Have you read?
Little more than a year ago, we hadn't heard of Thunberg. That changed after August 2018 when she held her first skolstrejk för klimatet, a 'school strike for climate', ducking out of class to protest outside Sweden's parliament.
Before long others joined her school strikes and, within a matter of months, a global movement was born. By March 2019, more than 2 million students across 135 countries were holding school strike demonstrations.
Thunberg has come a long way in a year, both literally and figuratively. In October she was awarded the 2019 Nordic Council Environment Prize, but turned it down because "the climate movement does not need any more awards," she said on Instagram.
She went on to say there is "no lack of bragging" about the Nordic countries' green credentials, but that "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."
Just weeks after her 16th birthday she attended the World Economic Forum’s Annual Meeting in Davos, where she famously urged world leaders to “panic” at the seriousness of the situation.
“I don’t want your hope,” she told the audience. “I want you to panic. I want you to feel the fear I do. Every day. And want you to act. I want you to behave like our house is on fire. Because it is.”
In March Thunberg was nominated for a Nobel Peace Prize. Time magazine named her one of the world's most influential people ans put her on its cover. She has addressed the European Parliament, the French National Assembly, the UK's House of Commons, and met with Pope Francis.
Now she is addressing the United Nations Climate Summit, a meeting she travelled to by carbon-neutral yacht.
“It is insane that a 16-year-old would have to cross the Atlantic to take a stand," she told reporters on arrival at the harbour. "The climate and ecological crisis is the biggest humanity has ever faced.”
And on the eve of the UN summit, she spearheaded an unprecedented global demonstration calling for action on climate change.
Sukhman Dhami, 41, who joined the New York leg of the protest, told Reuters: “Scientists establish the facts, but it’s up to communities and people to demand everyone act on this.
“Greta Thunberg has inspired millions of Gretas - young and old.”
What’s the World Economic Forum doing about climate change?
Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum's Global Risks Report continues to rank these environmental threats at the top of the list.
To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.
The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.
This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.
