The Atlantic has begun solving a big mystery in climate advocacy circles — how Jeff Bezos will spread around money from the $10 billion "Bezos Earth Fund" announced in February.

Why it matters: The fund's size makes it a huge presence in climate philanthropy. And, until now, the fund has been a mysterious presence, given the dearth of info and the broad scope of funding areas.

  • Bezos initially said the first grants would arrive in the summer, but that came and went.

Where it's going, per The Atlantic's reporting:

  • $100 million each to the Nature Conservancy, the Environmental Defense Fund, the Natural Resources Defense Council, the World Wildlife Fund and the World Resources Institute.
  • Grants of $10 million to $50 million for the Energy Foundation, the Union of Concerned Scientists, the ClimateWorks Foundation, and the Rocky Mountain Institute.

What we're watching: For the fund to roll out the grants, and more.

  • "This list does not reflect the complete range of organizations that the Earth Fund has been speaking with and that will be receiving grants from the fund in this initial round – stay tuned," a representative of the fund told the Atlantic (and Axios).

Exclusive: Slack goes solo for future-of-work VC fund

Slack is earmarking $50 million from its balance sheet to launch a new venture capital fund aimed at broadening Slack-backed investments beyond its own platform.

Why it matters: This is Slack's first solo turn at the VC game after a $25 million fund in collaboration with several of its own investors. With the pandemic confining many workers away from in-person interactions, countless companies are having to navigate a new way to operate—and new workplace apps are in the spotlight like never before.

Massachusetts Gov. Charlie Baker (R), a moderate who typically ranks as one of the nation's most popular governors, said Wednesday that he and Lt. Gov. Karyn Polito (R) will not seek third terms in 2022.

Why it matters: The decision leaves the gubernatorial race wide open and will likely affect multiple down-ballot races next year. Baker was expected to be the front-runner had he joined the race.

CDC prepares tougher testing rules for international travelers

The Centers for Disease Control and Prevention said Tuesday night that it is working to impose stricter testing requirements for international travelers due to the spread of the new Omicron variant.

The big picture: The new rules would require all international travelers, regardless of vaccination status, to show a negative test taken a day before their flight to the U.S. Currently, the CDC says fully vaccinated travelers are allowed to show a test taken no more than three days before their departure, AP reports.
