Former celebrity Charlotte Church took a break from “lowering and deferring” her tax today to sing a song titled “Requiem for Arctic Ice” in front of Shell’s London offices. She was taking part in a Greenpeace-organised musical protest against Shell’s Arctic drilling operations. It seems she was quite choked up after watching some ice melt:

“I can’t see how anyone could see footage of the Arctic melting and not feel moved. It’s terrifying to think of what we’re doing to this planet. This song just felt so appropriate to why I came here today. I wanted to capture the sorrow and regret that feels tied up with the melting ice, and the bitter irony of Arctic oil drilling.“

Taken aback by the power and sincerity of @charlottechurch's performance. Truly sensational. @GreenpeaceUK pic.twitter.com/s1Sqq9gKHu

Arctic sea ice increased by around a third last year…
