Warren's campaign says one of her existing policy proposals would create pressure on major oil-and-gas companies to splinter.

The intrigue: They pointed to her legislation that would require detailed disclosures from publicly traded companies about climate change.

  • Under her bill, filings with securities regulators would describe risks to the company from policies that would force steep emissions cuts consistent with holding global temperature rise to 1.5°C.

Why it matters: The campaign argues that this would lead to so-called stranded oil and natural gas reserves that would create big financial liabilities for energy companies.

Yes, but: The idea of stranded assets is controversial and beyond the scope of this blurb. And achieving emissions cuts consistent with 1.5°C is looking quite unlikely.

  • But those huge caveats aside, the campaign argues that this risk would push companies to break apart.

What they're saying: "If oil companies are required to disclose this information to investors, there will be enormous investor pressure on these companies to break up so that the non-fossil fuel parts of these companies would not be taken down by likely losses in the fossil fuel parts," Warren's campaign said.

The state of play: Warren touched on this goal in passing during Tuesday's Democratic debate when she was asked about her goal of breaking up tech giants.

  • "We need to enforce our antitrust laws, break up these giant companies that are dominating, Big Tech, Big Pharma, Big Oil, all of them," said Warren.

The bottom line: Warren is now the co-frontrunner with Joe Biden. It's another sign of the aggressive posture Warren has staked out.

Pfizer coronavirus vaccine safe, effective in children, company says

Pfizer and BioNTech's coronavirus vaccine is safe and effective in children ages 5 to 11, albeit at a lower dose than adults receive, the companies said in a press release announcing results from a pediatric trial.

Why it matters: The trial results are a much-needed source of hope for families with elementary school-aged children, who currently aren't eligible for a vaccine.

The pandemic made our workweeks longer

The average American's workweek has gotten 10% longer during the pandemic, according to a new Microsoft study published in Nature Human Behaviour.

Why it matters: These longer hours are a key part of the pandemic-induced crisis of burnout at U.S. firms — and workers are quitting in droves.

Airbnb CEO Brian Chesky to herald "travel revolution"

Airbnb CEO Brian Chesky will argue this week that the world is undergoing a "travel revolution," in which some parts of the industry stay shrunk but the sector ultimately comes back "bigger than ever."

Why it matters: Chesky, who faced the abyss when the world shut down last year, foresees a significant shift in how people move around, with more intentional gatherings of family, friends and colleagues — even if routine business travel is never what it once was.
