Teenage climate activist Greta Thunberg gotten here in New york city City on Wednesday after sailing throughout the Atlantic Ocean to call attention to the need for fast action to conserve the world.

Thunberg, a 16- year-old from Sweden, embarked in the racing sailboat Malizia II from Plymouth in the United Kingdom two weeks earlier on the trip to the U.S. to attend the United Nations Environment Action Top, which is set up to take place in September at the U.N.’s head office in New york city.

After disembarking from the vessel at a Manhattan marina, Thunberg was greeted by a crowd of advocates, consisting of a group of fellow high school students bring homemade signs. The trainees broke into chants as the sailboat slowly pulled into the marina in Lower Manhattan, including “Sea levels are rising therefore are we!” and “There is no World B!”

Thunberg appeared a little tired from her journey, but spoke forcefully about environment change. While she does not expect everyone to cross the Atlantic Ocean in a boat like she did, she stated that she thinks it’s time for people to come together to combat environment modification.

” The environment and environmental crisis is a global crisis and the biggest crisis humanity has actually ever dealt with,” she said quickly after she stepped on coast. “And if we don’t manage to collaborate and to comply … then we will fail.”

Thunberg stated that while she’s wanting to get the word out about climate modification, someone isn’t the primary focus of her message—- President Donald Trump.

” My message for him is simply listen to the science, and he undoubtedly doesn’t do that. As I always state to this question, if nobody has been able to convince him about the environment crisis, the seriousness, why should I have the ability to do that?” Thunberg said.

Thunberg launched her project for action on environment modification simply last August, when she sat outside of the Swedish Parliament in Stockholm holding an indication engraved with the expression, “Skolstrejk för Klimatet” (School Strike for Environment). In the year because, she assisted to arrange a March 15 strike thought to have actually been signed up with by 1.6 million people in 133 nations; met world leaders, consisting of Pope Francis; and was nominated for the 2019 Nobel Peace Prize.

Thunberg has actually accentuated the greenhouse gas emissions triggered by air travel. In Sweden, she is credited for the spread of “flygskam”—- flight embarassment—- which reports say might have motivated some Swedes to avoid taking a trip by plane.

The Malizia II is a 60- foot vessel is designed to be emission-free, and is geared up with photovoltaic panels, hydro-generators and an onboard laboratory for determining CO2 levels and other information about the surface of the ocean.

The teen set sail two weeks ago with a little group, including her father, Svante Thunberg, and co-skippers Pierre Casiraghi—- grand son of Rainier III, Prince of Monaco and Grace Kelly—- and professional sailor Boris Herrmann, who has circumnavigated the world 3 times and made “numerous” journeys throughout the Atlantic, according to Herrmann’s website

As the vessel was created for racing, it was developed for speed—- but not comfort. Herrmann’s site acknowledges that the boat does not have lots of amenities, consisting of cooking centers, a toilet and a shower, although “comfy bed mattress” were added for Thunberg’s trip.

Several young individuals stated that they had actually first discovered Thunberg from YouTube, however had actually been inspired to act due to the fact that they’ve learned how environment change is impacting individuals worldwide.

Olivia Wohlgemuth, a 16- year-old trainee at LaGuardia High School, informs TIME that while she’s worried about the future, protesting to raise awareness gives her hope.

” I always feel so hopeful at protests. Climate change can be so bleak and action can be an antidote to that,” Wohlgemuth said.

Several teenagers, consisting of 15- year-old Dwight School student Alessandro Dal Bon, said that Thunberg had actually been the inspiration for them to get involved with climate advocacy.

” She’s not afraid of anybody. She’s not scared of the political leaders, she’s not scared of the business people. She simply wishes to get her message out there. And she wants to do anything for that. She’s prepared to cross the Atlantic Ocean for 15 days on a little boat to do that. That simply reveals you how determined she is,” Dal Bon states.

Thunberg thanked the sailboat’s group and stated that the journey had actually been “remarkably great,” keeping in mind that she hadn’t gotten seasick. She said that she would miss out on feeling “detached” from the world throughout the journey.

” To just sit, actually sit for hours, and simply gaze at the ocean refraining from doing anything. That was excellent. And I’m going to miss out on that a lot,” Thunberg said. “And of course, to be in this wilderness, the ocean, and to see the beauty of it. “
