Stephen Hahn, the commissioner of the Food and Drug Administration, warned on NBC's "Meet the Press" Sunday that antibody tests for the coronavirus that haven't undergone the FDA's scientific review "may not be as accurate as we'd like them to be."

Why it matters: Developing the antibody tests, which are used to determine whether a person previously had the coronavirus and is therefore immune, will be crucial to understanding the scale of the outbreak. Some U.S. officials consider the development of an effective test to be a key step in being able to reopen the economy.

  • So far, the FDA has authorized only one antibody test under an "Emergency Use Authorization."

What they're saying: "We know that no test is 100% perfect," Hahn said. "But what we don't want are widely inaccurate tests because as I said before, that's going to be much worse having wildly inaccurate tests than having no tests."

Why the pandemic's carbon cuts still won't head off a climate emergency

Global carbon emissions from energy, which are the lion's share, will never fully come back from pre-pandemic levels — recovering from a pandemic-fueled decline but sinking again around 2027 with renewable energy on the rise — according to a BloombergNEF analysis.

But, but, but: It still won't prevent the planet from cooking, as the firm still sees enough emissions to lead to over 3.3°C of warming above preindustrial levels by century's end.
