Sen. Amy Klobuchar (D-Minn.) jumped into the White House race yesterday, and her speech's climate lines are worth breaking down:

"The people are on our side when it comes to climate change. Why? Because like you and I, they believe in science. That's why in the first 100 days of my administration, I will reinstate the clean power rules and the gas mileage standards and put forth sweeping legislation to invest in green jobs and infrastructure. And on day one, we will rejoin the international climate agreement."

Quick take: Maybe I'm reading too much into it, but it can be viewed as a mix of ambition and an implicit nod to the daunting legislative hurdles in front of moving a big bill.

  • Reinstating former President Obama's Clean Power Plan is hardly the most ambitious goal in the world — that rule would have largely provided a regulatory backstop for trends already apparent in the power sector.
  • Reinstating the auto mileage rules would be a return to what was already on the books before Trump-era rollbacks began. Ditto for recommitting to the Paris agreement, which President Trump plans to abandon.

But, but, but: Klobuchar is among the Senate sponsors of the Green New Deal resolution, so there's one template for the "sweeping legislation" she mentions.

  • But it's extraordinarily unlikely that Democrats will have a filibuster-proof majority in the Senate even if they retake the chamber in 2020, so big legislation is a long shot.

The big picture: Climate change is playing an improbably large role in the early 2020 jockeying. The latest example came yesterday evening, when Trump inaccurately suggested (again) that cold weather somehow disproves climate change.

  • Trump mocked Klobuchar on Twitter for "talking proudly of fighting global warming while standing in a virtual blizzard of snow, ice and freezing temperatures."
  • "Science is on my side, @realDonaldTrump. Looking forward to debating you about climate change (and many other issues)," Klobuchar responded, also on Twitter.

Czech police on Saturday connected two Russian men suspected of carrying out a poisoning attack in Salisbury, England, with a deadly ammunition depot explosion southeast of the capital, Prague, per Reuters.

Driving the news: Czech officials announced Saturday they're expelling 18 Russian diplomats they accuse of being involved in the blast in Vrbětice, AP notes. Czech police said later they're searching for two men carrying several passports — including two with the names Alexander Petrov and Ruslan Boshirov.

Indianapolis mass shooting suspect legally bought 2 guns, police say

The suspected gunman in this week's mass shooting at a FedEx facility in Indianapolis legally purchased two "assault rifles" believed to have been used in the attack, police said late Saturday.

Of note: The Indianapolis Metropolitan Police Department's statement that Brandon Scott Hole, 19, bought the rifles last July and September comes a day after the FBI told news outlets that a "shotgun was seized" from the suspect in March 2020 after his mother raised concerns about his mental health.

U.S. and China agree to take joint climate action

Despite an increasingly tense relationship, the U.S. and China agreed Saturday to work together to tackle global climate change, including by "raising ambition" for emissions cuts during the 2020s — a key goal of the Biden administration.

Why it matters: The joint communique released Saturday evening commits the world's two largest emitters of greenhouse gases to work together to keep the most ambitious temperature target contained in the Paris Climate Agreement viable by potentially taking additional emissions cuts prior to 2030.
