Two architects of the Paris Climate Agreement present a pair of possible scenarios for the global climate in 2050 — one in which we've met the carbon reduction targets laid out in the agreement, and one in which we've failed.

Why it matters: The authors argue that we have a decade left to pick which path the planet will take: catastrophe or hope.

Former United Nations Framework Convention on Climate Change head Christiana Figueres and climate diplomat Tom Rivett-Carnac were instrumental in guiding the Paris Agreement, which committed countries to reducing carbon emissions sufficiently to keeping global temperature rise below at least 2° C by 2100.

  • In their new book The Future We Choose: Surviving the Climate Crisis, the pair sketch out what the climate could look like by mid-century, depending on whether we meet the Paris goals.
  • If we succeed, they foresee a world where forests cover half the land surface, air pollution has disappeared and fossil fuels have been eliminated.
  • If we fail, warming will be on a pace for a 3°C increase by 2050, the air will become unbreathable and the very future of human civilization will be in doubt.

What they're saying: "If we continue where we are now, we are going to be irreparably going down a course of constant destruction," Figueres told the Guardian.

  • Altering that path will require sharp technological and political change, especially in the U.S. The choices made in 2020 will help decide the climate in 2050.

Democratic and Republican lawmakers along with other leading figures paid tribute to Supreme Court Justice Ruth Bader Ginsburg, who died on Friday night at age 87.

What they're saying: “Our Nation has lost a jurist of historic stature," Chief Justice John Roberts said. "We at the Supreme Court have lost a cherished colleague. Today we mourn, but with confidence that future generations will remember Ruth Bader Ginsburg as we knew her — a tireless and resolute champion of justice.”

Justice Ruth Bader Ginsburg has died of metastatic pancreatic cancer at age 87, the Supreme Court announced Friday evening.

Why it matters: Ginsburg had suffered from serious health issues over the past few years. Her death sets up a fight over filling a Supreme Court seat with less than 50 days until the election.

NYT: White House drug price negotiations broke down over $100 "Trump Cards"

Negotiations on a deal between the White House and pharmaceutical industry to lower drug prices broke down last month after Mark Meadows, the president's chief of staff, insisted that drugmakers pay for $100 cash cards to be mailed to seniors before the election, according to the New York Times.

Why it matters: Some of the drug companies feared that in agreeing to the prescription cards — reportedly dubbed "Trump Cards" by some in the pharmaceutical industry — they would boost Trump's political standing weeks ahead of Election Day with voters over 65, a group that is crucial to the president's reelection bid, per the Times.
