Swedish teen climate activist touring Dakotas reservations A 16-year-old climate activist who garnered international attention when she scolded world leaders at the United Nations is visiting American Indian reservations in the Dakotas to talk about oil pipelines

PINE RIDGE, S.D. -- A 16-year-old climate activist who garnered international attention when she scolded world leaders at the United Nations is visiting American Indian reservations in the Dakotas to talk about oil pipelines.

Greta Thunberg appeared Sunday in a youth panel discussion on the Pine Ridge Reservation in South Dakota. A similar event is planned Tuesday morning on the North Dakota side of the Standing Rock Reservation.

The Lakota People's Law Project says Thunberg is concerned about the proposed path of the Keystone XL pipeline through South Dakota, as well as plans to double oil flowing through the Dakota Access pipeline in North Dakota.

Thunberg traveled to the United States in August on a sailboat to promote her climate change campaign.
