Frontrunner Joe Biden and Sen. Elizabeth Warren's respective plans to combat climate change, which were unveiled Tuesday, both call for creating new federal agencies.

Why it matters: The plans signal acknowledgment that the federal government's existing structures are imperfectly aligned to spur deep emissions cuts.

Where it stands: Warren's $2 trillion "green manufacturing" plan would form a National Institutes of Clean Energy. Biden wants to create a cross-agency Advanced Research Projects Agency for climate (ARPA-C).

There are other examples. Washington Gov. Jay Inslee's platform, for instance, revives the idea of creating a federal Clean Energy Deployment Authority (or "green bank").

But, but, but: There are tradeoffs. Standing up new bureaucracies takes time and often congressional authorization.

  • There's also some controversy attached to Biden's plan, after his campaign "amended his climate policy plan hours after it was released Tuesday because a handful of passages did not credit some of the sources in the proposal," AP reports.

Go deeper: NYT's Brad Plumer tweeted helpful comparisons of the price tag of candidates' climate plans.

Biden confronts mounting humanitarian crisis at the border

Just over a month into his presidency, President Biden is staring down a mounting crisis at the border that could be just as bad as the ones faced by Barack Obama and Donald Trump, if not worse.

  • Why it matters: Immigration is an issue that can consume a presidency. It's intensely and poisonously partisan. It's complicated. And the lives and welfare of vulnerable children hang in the balance.

The backstory: Biden came into office sounding a warmer, more welcoming policy that would treat migrants humanely. Desperate people have taken notice.

  • And Biden reversed Trump’s COVID-era policy of turning away unaccompanied children — the very group that is now surging and being held for days in border stations unfit for children.

What's happening: Shelters are overflowing. Border crossings are rising. Border Patrol facilities are overwhelmed. And the new administration is taking fire from both the left and right as it grapples with the issue's harsh realities.

The rise of vaccine passports

Vaccine passports were touted early in the pandemic as an important piece of the plan to get people back to normal life. Now they’re becoming a reality.

Driving the news: CLEAR, the secure digital identity app that you see in airports around the world, and CommonPass, a health app that lets users securely access vaccination records and COVID test results, have joined forces.

"Vaccine tourism" stretches states' supplies

Americans who are highly motivated to get vaccinated are traveling across state lines after hearing about larger vaccine supplies or loopholes in sign-up systems.

Why it matters: "Vaccine tourism" raises ethical and legal questions, and could worsen the racial socioeconomic and racial inequalities of the pandemic.
