A new peer-reviewed paper cuts against the grain by concluding that the most effective carbon tax structure should start high and decline over time.

Why it matters: It breaks with carbon tax bills floating around Congress and other proposals that begin modestly and then escalate.

What they found: The paper in the Proceedings of the National Academy of Sciences journal offers several reasons for flipping the script.

  • Uncertainty around just how bad damage from climate change could be makes strong near-term steps vital.
  • The high costs of delaying action.
  • Falling costs of cutting emissions over time as technology improves.

The big picture: The paper's modeling suggests an optimal price would begin at well over $100-per-ton (or even much higher), rise for a few years, and then fall.

"[P]roperly taking climate uncertainty into account leads to the conclusion that we need to take stronger action today to give us breathing room in the event that the planet turns out to be more fragile than current models predict."
— Kent Daniel, lead author and professor at Columbia Business School, per statement

Where it stands: It's very different than what's out there now.

  • The nonprofit Climate Leadership Council, which includes Big Oil backers, is circulating a plan that starts at $40-per-ton of CO2 and rises annually.
  • A Columbia University energy think tank has a helpful tally of Capitol Hill plans that all start with far lower CO2 prices than the PNAS paper suggests.

But, but, but: "Treat carbon in the atmosphere like an asset (with negative payoffs) and apply Financial Economics 101, and its price appears to jump by quite a bit over typically modeled prices," PNAS co-author Gernot Wagner tells me.

In cyber espionage, U.S. is both hunted and hunter

American outrage over foreign cyber espionage, like Russia's SolarWinds hack, obscures the uncomfortable reality that the U.S. secretly does just the same thing to other countries.

Why it matters: Secrecy is often necessary in cyber spying to protect sources and methods, preserve strategic edges that may stem from purloined information, and prevent diplomatic incidents.

The Biden White House is deploying top officials to get a wide ideological spectrum of lawmakers, governors and mayors on board with the president’s $1.9 trillion COVID relief proposal, according to people familiar with the matter.

Why it matters: The broad, choreographed effort shows just how crucially Biden views the stimulus to the nation's recovery and his own political success.

Scoop: Sudan wants to seal Israel normalization deal at White House

Three months after Sudan agreed to normalize relations with Israel, it still hasn't signed an agreement to formally do so. Israeli officials tell me one reason has now emerged: Sudan wants to sign the deal at the White House.

Driving the news: Israel sent Sudan a draft agreement for establishing diplomatic relations several weeks ago, but the Sudanese didn’t reply, the officials say. On Tuesday, Israeli Minister of Intelligence Eli Cohen raised that issue in Khartoum during the first-ever visit of an Israeli minister to Sudan.
