MADRID (AP) - The Spanish government has offered assistance to Swedish climate activist Greta Thunberg to facilitate her participation in the UN Climate Change Conference in Madrid in December.

"Dear Greta, it would be great to have you here in Madrid," said Acting Environment Minister Teresa Ribera on Twitter. "We would love to help you cross the Atlantic," she added in the tweet on Friday evening, praising Thunberg's commitment to the climate. Madrid is ready to get in touch with the 16-year-old. As the travel help might look like, Ribera did not say.

After the surprising rejection of Chile, the Spanish capital has stepped in as host of the UN Climate Change Conference. The top meeting will take place from 2 to 13 December.

Thunberg has announced that she wants to be there despite the change of location. However, she must now find a way to cross the Atlantic, wrote the founder of the climate movement Fridays for Future on Twitter. "It turns out that I traveled halfway around the world, in the wrong direction," she wrote from the USA. If someone could help find a means of transport, she was grateful.

Thunberg was on a sailing ship across the Atlantic, because she did not want to fly as a sign of more climate protection. She spoke to the United Nations in New York, but the planned climate change conference in Santiago de Chile was one of the reasons for the arduous journey. After Chile had canceled this because of the violent social protests in the country, Spain jumped in. At the UN climate summit, states are negotiating the implementation of the Paris Climate Agreement. Its aim is to limit the earth heating to below two degrees.
