At Wednesday night's climate change town hall, top Democratic presidential candidates will be challenged to lay out a climate strategy that is both effective and politically viable.

The big picture: Despite efforts by state governments and the private sector, the U.S. has a long way to go to formulate a coherent and globally credible climate strategy. A dedicated town hall offers Democratic primary voters a chance to scrutinize proposals like the sweeping Green New Deal and it reflects their growing sense of urgency around climate change.

What to watch: In the world of climate policy, there are technically credible plans that lack meaningful political support and bold political calls to action that neglect business, market and technical concerns. Candidates hoping to bridge that divide must attend to several overarching issues:

  • Reconciling climate action with populism and nationalism. Australia, Brazil and Canada have seen voters repudiate climate-centric strategies, and the question of “who pays” for climate action has sparked protests like France's “gilets jaunes” movement. Even in “deep blue” Washington state, a carbon tax ballot initiative was defeated in 2016 and again in 2018.
  • Wrestling with the future of oil and gas. Substitutes for petroleum fuel are still not at scale, particularly for trucking, shipping, rail and aviation. Two key questions, especially for voters in battleground states like Colorado and Pennsylvania, will be the speed of the transition candidates envision and how they see U.S. oil and gas exports fitting into it, if at all.
  • Weighing the role of carbon taxes. Debate has swirled around the right tax rates to decrease demand and whether to offset such taxes with consumer rebates or reductions in other types of taxes.

The bottom line: The town hall provides an initial opportunity for Democrats to convince voters that climate deserves to be more than what Trump calls a “niche” issue, but there is a long campaign ahead and no shortage of competing issues.

Joe Biden expanded his energy and climate plans Tuesday with a call for spending $2 trillion over four years on climate-friendly infrastructure — a proposal the campaign is casting as part of a wider economic recovery package.

Why it matters: The plan, which is the focus of a speech Biden will deliver this afternoon, represents a long-anticipated plan to move his climate platform further left and make it more expansive.

4 former CDC heads say Trump's undermining of agency puts lives at risk

Four former directors of the Centers for Disease Control and Prevention blasted the Trump administration's "repeated efforts to subvert" agency guidelines related to reopening schools, accusing the White House in a scathing Washington Post op-ed of undermining science with "partisan potshots."

Why it matters: Former directors Tom Frieden, Jeffrey Koplan and David Satcher and acting head Richard Besser served in parts of the Obama, Bush and Clinton administrations. They said they "cannot recall over our collective tenure a single time when political pressure led to a change in the interpretation of scientific evidence."

Chinese students at U.S. colleges face deep uncertainty

A new visa guideline issued last week would strip international students in the U.S. of their student visa if their college classes are online-only amid the pandemic.

Why it matters: More than 360,000 Chinese students are enrolled at U.S. colleges. Many of them could be forced to return to China if the rule change is implemented.
