Greta Thunberg Hitches A Ride With Aussie Family To COP25 Summit

When Greta Thunberg needed help getting to Madrid, this Aussie sailing vlogging duo was ready to let her hitch a ride.

The teen climate activist will soon share a ride across the Atlantic on board the couple's yacht to attend a UN climate conference later this month.

Thunberg, 16, found herself stranded in the US when the COP25 Summit was relocated from Santiago, Chile, to the Spanish city.

She put a call out on social media for some help.

"It turns out I've travelled half around the world, the wrong way," Thunberg tweeted on November 1.

"Now I need to find a way to cross the Atlantic in November ... if anyone could help me find transport, I would be so grateful."

Four days later,  Australian Riley Whitelum replied on Twitter with an offer of help.

"Greta it's Riley here from Sailing La Vagabonde. If you get in contact with me I'm sure we could organise something," he wrote.

Thunberg chooses not to fly due to the carbon emissions caused by planes.

In August, she travelled from the coast of England to New York on a zero-emissions racing yacht to attend the UN Action on Climate Change Summit. Since then, she has travelled through the US by boat, train and electric car.

Enter 'La Vagabonde'.

On Tuesday night, Thunberg said she had been offered a ride from Virginia on board the 48-foot sailing catamaran with Whitelum and his partner Elayna Carasau along with professional yachtswoman Nikki Henderson.

"So happy to say that I'll hopefully make it to COP25 in Madrid," Thunberg wrote on social media.

"We sail for Europe tomorrow morning!"

Whitelum and Carausu have been sailing around the world on board 'La Vagabonde' since 2014. The couple, who have a son, are documenting their journey on YouTube and post a new video each week.

"We’ve suffered terrifying storms, pirate scares, financial breakdowns, equipment failures, water shortages, and other interesting mishaps but we wouldn’t trade living on the sea and going where the wind takes us for anything," their website reads.

Their YouTube page has about 1.17 million subscribers.

Now, they have an even more public adventure on their hands.

"Guess what. We're about to sail Greta Thunberg across the Atlantic," Carausu wrote on Instagram.

Since starting their sailing journey five years ago, the Aussie couple has travelled over 90,000 nautical miles.

For this adventure, they'll be joined by Nikki Henderson, who last year became the youngest skipper to lead a team in the Clipper Round The World Yacht Race at the age of 25.

"Wish us windy and positive vibes and fingers crossed we make it in time to deliver Greta Thunberg safely to COP25," Henderson wrote on Instagram.

The COP25 Summit will take place in Madrid from December 2 - 13.
