Millions of people demonstrated across the world yesterday demanding urgent action to tackle global heating, as they united across timezones and cultures to take part in the biggest climate protest in history.

In an explosion of the youth movement started by the Swedish school striker Greta Thunberg just over 12 months ago, people protested from the Pacific islands, through Australia, across-south east Asia and Africa into Europe and onwards to the Americas . . .

 . . . Trade unions representing hundreds of millions of people around the world mobilised in support, employees left their workplaces, doctors and nurses marched and workers at firms like Amazon, Google and Facebook walked out to join the climate strikes . . .
