'No sea sickness so far': Greta Thunberg update on Atlantic crossing

Climate activist is four days into a two-week journey on solar-powered yacht

Four days into its two-week Atlantic crossing, the solar-powered yacht carrying climate activist Greta Thunberg is becalmed in the ocean after a choppy start to the trip, still 2,500 nautical miles from New York.

In an update posted to Twitter around midday on Saturday, the 16-year-old said she was eating and sleeping well and had no sea sickness so far.
