Occasionally, just occasionally, there are weeks full of silver linings. The one that saw Britain's first nationwide schools climate strikes was definitely one of them.
When Greta Thunberg began her lone climate protest outside the Swedish Parliament last August she was not to know that, within 6 months there would be 70,000 pupils a week, across 270 towns and cities worldwide, who would be joining her. Their message was simple: "Wake up! There's a climate emergency."
If you had followed the week's debates in Britain's Parliament you wouldn't have guessed.
