As his first book, New York Magazine national correspondent Gabriel Debenedetti is writing a book for Henry Holt & Co. on the "long, winding arc of the close, complex relationship between Joe Biden and Barack Obama."

What they're saying: I'm told that the book, which doesn't have a publication date, "will take a long view of the unprecedented relationship between the two presidents, looking at how the true, intricate stories of their intertwined careers — from the Senate to the White House, to the Trump era and back — goes far deeper than the popular bromance narrative."

Gabe tells me: "I've been covering Joe Biden, Barack Obama, and the Democrats for years, and the two presidents' thoroughly consequential relationship has always fascinated me — but never more than it did in the final weeks of the general election, and now during the transition."

Japan on Thursday said it will seek to cut greenhouse gas emissions by 46% below 2013 levels by 2030, per the AP and other outlets.

Why it matters: The country is the world's fifth-largest largest carbon dioxide emitter and a major consumer of coal, oil and natural gas.

The global race to regulate AI

Regulators in Europe and Washington are racing to figure out how to govern business' use of artificial intelligence while companies push to deploy the technology.

Driving the news: On Wednesday, the EU revealed a detailed proposal on how AI should be regulated, banning some uses outright and defining which uses of AI are deemed "high-risk."

The Biden administration is moving to address global warming by setting a new, economy-wide greenhouse gas emissions reduction target of 50% to 52% below 2005 levels by 2030.

Why it matters: The new, non-binding target is about twice as ambitious as the previous U.S. target of a 26% to 28% cut by 2025, which was set during the Obama administration. White House officials described the goal as ambitious but achievable during a call with reporters Tuesday night.
