Thursday's debate nicely encapsulated the way that climate change has become stitched into the fabric of wider Democratic policy and messaging on many topics.

The state of play: While a huge Green New Deal-style mobilization lacks legs in Congress, its all-encompassing conceptual framing — climate as inseparable from industrial policy, human rights and much more — is carrying the day.

The big picture: The segment on climate and other answers included the following comments — and this is not a comprehensive list:

  • Bernie Sanders, after the climate section was over, used a question about the lack of diversity on stage to revisit the topic. "People of color, in fact, are going to be the people suffering most if we do not deal with climate change," he said.
  • Elizabeth Warren used a question about climate change to quickly transition to her wider populist message, noting that "if we don't attack the corruption first, if we don't attack the corruption head-on, then we're not going to be able to make the changes we need" on climate and other topics.
    • She also said that while she's against building new nuclear plants, the need to stem carbon emissions means "we need to keep some of our nuclear in place."
  • Joe Biden was quick to play up job creation from building out climate-friendly infrastructure. I know, I know, green jobs messages are hardly new, but the economic frame around climate is in full flower this cycle.
    • He had a moment of candor when asked whether he'd sacrifice some U.S. oil-and-gas production growth even knowing it could displace workers in those sectors. "The answer is yes because the opportunity for those workers to transition to high-paying jobs...is real," he said, talking up jobs in low-carbon infrastructure.
  • Tom Steyer returned to climate when making the wider argument for treating China as a "frenemy," noting, "if we are going to treat climate as the threat that it is, we are going to have to partner with the Chinese." Whether that proves to be a political winner in a general election is TBD.

The Democratic fight to shape Biden's climate policy

Left-wing climate activists don't want Joe Biden getting advice from people with credentials they don't like — and they're increasingly going public with their campaign.

Why it matters: Nobody is confusing Biden with President Trump, and his climate platform goes much further than anything contemplated in the Obama years.

With college football on the brink, Monday saw an outpouring of support for playing a fall season from numerous parties, including President Trump, Ohio State coach Ryan Day and Michigan coach Jim Harbaugh.

Yes, but: Monday also saw the Mountain West Conference become the second FBS league to postpone fall sports, and the Big Ten and Pac-12 are expected to make the same decision as early as this morning.

Former President Obama and First Lady Michelle Obama will headline two nights of the Democratic National Convention, according to a full list of speakers released by the party on Tuesday.

Our thought bubble, via Axios' Margaret Talev: It signals how much the Democratic Party is still the party of Barack Obama — and how strongly Biden’s team feels the Obamas can validate his vice presidential choice and energize the party’s base.
