Greta, don’t sink the green message

Sweden’s teenage climate change campaigner, Greta Thunberg, is now well on her way to New York, aboard the carbon-neutral racing yacht generously provided by a member of Monaco’s royal family.

She’ll be speaking at a United Nations climate conference where, doubtless, politicians — few, if any of whom, will have travelled there on a latrine-free vessel — will be lining up to be photographed with her.
