The Green Party's Caroline Lucas says today's protest shows that young people "simply won't wait any longer" for world leaders to take action over the climate crisis.
The MP, who attended the demonstration in London today, said: "It feels like there is a real uprising. It feels like there is a real sense from young people in particular that they simply won't wait any longer.
"It is their future that is at stake and our generation, my generation, is responsible for not having done nearly enough to address that.
"They have enormous moral authority when they tell us that."
Lambeth Bridge has reopened after protesters blocked the road as part of the global climate strike.

Greta Thunberg has said the huge numbers of people who are out demonstrating today is a "victory".
The 16-year-old activist, who was instrumental in sparking the global movement, watched news of climate strikes in Australia and the Pacific before going to bed in New York last night.

It is now up to world leaders to act, the teenager said, adding they should "feel ashamed" if they don't.
Eight people have been arrested at the climate protest in London today, the Metropolitan Police has said.
Seven of those were for breaching conditions the force placed on the demonstrations. The Met had issued a section 14 order which restricted protesters to an area in Westminster and required the action to conclude by 3.30pm.
The arrests come after a small group of protesters attempted to block Lambeth Bridge. One man was also detained on suspicion of discharging a flare in a public place.
