The movement is just one of dozens that will happen around the world, inspired by Swedish teenager Greta Thunberg, who has been holding weekly protests in front of Sweden's parliament since August 2018. The then-15-year-old skipped school for three weeks and sat outside the country's Parliament building with a sign demanding radical action from government on climate change.
"Politicians have known the truth about climate change, and they've willingly handed over our future to profiteers whose search for quick cash threatens our very existence". Protests were underway or planned in cities in more than 100 countries, including Hong Kong; New Delhi; Wellington, New Zealand; and Oulu, Finland.

Over the past half year, Thunberg has been taking world leaders to task over climate inaction with blunt, fiery speeches.
Kalmus said that he is starting to see a difference in how climate change is being discussed more seriously in the media and by politicians and that these kids can be part of the dialogue and the solution as well.
Tomorrow, however, Greta and her fellow environmentalists are gearing up for their largest worldwide protest yet, with thousands of schoolchildren attending protests in 105 different countries - and counting.
A website used to coordinate the rallies listed events in over 2,000 cities.
"We don't have the time to wait, that's not a luxury that we have anymore", says 17-year-old Katie Hutten.
For her, the takeaway isn't the fact that children are protesting, but why young people have taken to the streets: "They talk about our age, our looks and so on".

"We are the professionals and we're saying the young generation is right", said Volker Quaschning, a professor of engineering at Berlin's University of Applied Sciences.
Yesterday, students from six other schools gathered at Newpark Comprehensive School in Dublin to plan for tomorrow's Dublin protest.

The world is now 1ºC warmer than preindustrial levels.
The planet is now on track to heat up by double that figure. This would give less-advanced nations a bit more time to wean themselves off fossil fuels while still meeting the Paris goal globally.
German Chancellor Angela Merkel and French President Emmanuel Macron have publicly welcomed the student protests, even as their policies have been criticized as too limited by environmental activists.
There are marches scheduled at 1,769 sites in 112 countries. The margin of error was about 3 percentage points.
Greta Thunberg, in August a year ago, became the face of a "school strike" outside the Swedish parliament building.
"Tomorrow we schoolstrike for our future", she added in another post. "So, alright, how can we solve it?' They tend to pivot quickly to discuss solutions".
"But if we don't strike and demand that our leaders take action, we're not going to have a habitable planet to live on in the future".More news: Royal household split - Prince Harry and Meghan go it alone
