16-year-old Swedish climate activist Greta Thunberg will visit Standing Rock Reservation and the Pine Ridge Reservation in North Dakota and South Dakota this week, the Sioux Falls Argus Leader reports.

Why it matters: Thunberg, who gave a scathing speech attacking world leaders for their inaction in the face of climate change at the United Nation's 2019 General Assembly, will be participating on panels about the environmental effects of 2 proposed oil pipelines that ignited protests in 2016 and 2017.

Details: Thunberg will participate on a panel on Sunday about the Keystone XL pipeline at the Red Cloud Indian School Field House on the Pine Ridge Reservation in South Dakota.

  • On Tuesday, she'll participate in a forum on the Dakota Access Pipeline at the Standing Rock High School in Fort Yates, North Dakota.

Context: TC Energy's (formerly TransCanada) Keystone XL pipeline is a proposed addition to the Keystone Pipeline System. The Keystone XL would carry oil from Canada across Montana and South Dakota to Steele City, Nebraska. In South Dakota, the XL would run near the Pine Ridge and Rosebud reservations.

  • TC Energy on Oct. 4 informed a federal court that it would begin preparing for the XL's construction in South Dakota and Montana, according to the Rapid City Journal.
  • The Keystone Pipeline System, which runs through eastern North Dakota, South Dakota and Nebraska, leaked 210,000 gallons of oil in eastern South Dakota on Nov. 17, 2017.

The Dakota Access Pipeline starts in North Dakota and runs for 1,172 miles through South Dakota and Iowa to oil terminals in Illinois.

  • In North Dakota, it runs near the Standing Rock Reservation and under Lake Oahe, the reservation's main source of water.
  • Lake Oahe's river crossing was the center of protests over potential water contamination and damage to sacred tribal sites in 2016 and 2017.

Of note: Thunberg will join fellow youth climate activist and indigenous rights advocate Tokata Iron Eyes on both panels.

John Roberts' long game

Supreme Court Chief Justice John Roberts is not the revolutionary that conservative activists want him to be.

He moves slower than they want, sides with liberals more than they want, and trims his sails in ways they find maddening. But he is still deeply and unmistakably conservative, pulling the law to the right — at his own pace and in his own image.

The U.S.' new default coronavirus strategy: herd immunity

By letting the coronavirus surge through the population with only minimal social distancing measures in place, the U.S. has accidentally become the world’s largest experiment in herd immunity.

Why it matters: Letting the virus spread while minimizing human loss is doable, in theory. But it requires very strict protections for vulnerable people, almost none of which the U.S. has established.

Airline recovery falters before it even gets off the ground

Any hope for a rebound in air travel this year has vanished, with coronavirus cases surging in much of the U.S. and some states imposing quarantines to keep visitors away.

Why it matters: The airline industry is already suffering the worst crisis in its history. The soaring infection rates mean planes will be grounded even longer, putting tens of thousands of people out of work in the coming months.
