Watch: youth activists stage global climate strike in Berlin

Youth activists staged a coordinated "global climate strike" on Friday to highlight their fears about the effects of global warming and demand more aid for poor countries hit by wild weather.

Protesters took to the streets in Berlin carrying banners and posters with slogans such as "Our future hangs by a thread" and "It's not too late."

The demonstrations were organized worldwide by the Fridays for Future youth movement that took its cue from activist Greta Thunberg, who began protesting alone outside the Swedish parliament in 2018.

Thousands of people attended the rally in Berlin, which featured calls for the German government to establish a 100-billion-euro fund for tackling climate change.

"We're striking all over the world because the governments in charge are still doing too little for climate justice," said Darya Sotoodeh, a spokesperson for the group's chapter in Germany.

"People all over the world are suffering from this crisis and it's going to get worse if we don't act on time," she said.

The protests are taking place against the backdrop of warnings from scientists that countries aren't doing enough to meet the 2015 Paris climate accord's top-line target of limiting global warming to 1.5 degrees Celsius (2.7 Fahrenheit) this century compared to preindustrial times.
