The number of coronavirus diagnostic tests being completed every day has plateaued over the last week — at a number that falls far short of what experts say is needed.

Between the lines: Some states are testing more than others, but we’ve got a long way to go before we’re ready to safely resume normal life. Otherwise, the virus will easily be able to spread undetected.

  • Ashish Jha, director of the Harvard Global Health Institute, said he thinks we need to be doing 500,000 tests a day for the foreseeable future.

Nationwide testing capacity steadily increased for weeks, but has appeared to hit a wall around 145,000 tests a day. Several factors are holding it back:

  • Supply shortages for key test ingredients, swabs, test kits, and personal protective equipment.
  • Poor coordination: Some labs have excess testing capacity, but aren’t being sent samples from the providers collecting them.
  • Rules about who gets tested: Many states have limited testing to the sickest patients, and caseloads are dropping overall. But clinicians often have discretion as to who they test.

Variation among states isn’t only a result of demand. For example, Michigan is a hotspot for cases, but is near the bottom of the pack in testing.

  • States are competing for resources, and some have better existing infrastructure than others.
  • “Every state has come up with its own policy for testing, and most states are relying on a mix of different factors for how to do testing,” Jha said.

A big, UN-backed umbrella group of banks, asset managers, investors and insurers launched Wednesday to boost private clean tech finance and press polluting industries that use their services to cut emissions.

Why it matters: The Glasgow Financial Alliance for Net Zero (GFANZ) is the broadest financial industry effort yet on climate change.

Former New Jersey Gov. Chris Christie is seriously considering running for president in 2024, three people familiar with his thinking tell Axios.

Driving the news: While Christie isn't saying anything publicly about his thinking — besides telling radio host Hugh Hewitt he's not ruling it out — people close to him have an early sense of the rationale and outlines of a potential candidacy.

Chinese President Xi Jinping will attend President Biden's virtual climate summit this week, according to China's foreign ministry.

Why it matters: It'll mark the first time the two leaders have met face to face — albeit virtually — since Biden took office. China and the U.S. are the world's two largest carbon emitters.
