Teen climate activist Greta Thunberg has announced she will sail across the Atlantic ocean with a pair of Australian YouTubers, using their high-tech catamaran on the voyage from the United States to Spain.

Taking to Twitter, the immensely influential 16-year-old said she has teamed up with Riley Whitelum and Elayna Carausu for the journey to Madrid’s COP25 conference.

If Thunberg sailing across the Atlantic sounds familiar to you, that’s because it is. In August, Thunberg stowed herself aboard the solar-powered Maliza II racing yacht on its journey from the UK to New York City, where she delivered her famous speech at the United Nations Climate Action Summit.

She was meant to follow that date by visiting the COP25 in Santiago, Chile, but civil unrest in the South American nation forced the event’s relocation to Spain – which is, quite annoyingly, back on the other side of the Atlantic.

Thunberg, naturally averse to carbon emissions caused by passenger jet travel, sought another carbon-light ride across the waves.

Enter Whitelum and Carausu, whose YouTube channel, Sailing La Vagabonde, showcases their adventures aboard a you-beaut catamaran. Their channel has amassed a cool 1.17 million subscribers, and you can expect that number to climb thanks to their new VIP passenger.

PEDESTRIAN.TV has reached out to the couple for comment. Given the fact they leave bloody tomorrow, it seems unlikely they’ll have time to respond, but watch this space.
