Climate strikes continue online: 'We want to keep the momentum going'

Activists hold mass video calls and share hashtags, and three-day livestream planned for Earth Day

The large crowds and brightly coloured placards of the school climate strikes became some of the defining images of 2019.

"There would be lots of chanting and the energy was always amazing," says Dominique Palmer, a 20-year-old climate activist from London who has been involved with the strikes for more than a year. "Being there with everyone in that moment is truly an electrifying feeling. It's very different now."
