Children may have skipped school to campaign on climate change - but taught a lesson or two on how to write a protest banner

Schools climate strike: the best protest banners and posters

Some were witty, some were rude and some – for older people at least – were incomprehensible.

The thousands of children who left class on Friday to protest against inaction on climate change brought with them a dazzling array of protest banners and posters.

Here are some of the best – from the streets and from social media.
