A new study reveals global forest cover is at least 9% higher than previously thought — that amounts to 467 million hectares of forest that haven't ever been reported before.

Why it matters: These forests contain some of the "most threatened, yet disregarded, ecosystems." Plus these forests act as sinks by storing carbon in plants, trees, and soil and keep it from circulating in the atmosphere. These additional hectares of forest are likely to change estimates of how much carbon can be held by Earth's vegetation, which is thought to have an upper limit, according to the IPCC.

Why we're just hearing this: Previous estimates of dryland forests have been disputed due to differences in satellite spatial resolution, mapping techniques, and the definition of forests themselves (for example, how much tree coverage constitutes a forest).

Methodology: The research team used satellite data from Google Earth to examine a sample pool of 213,795 0.5-hectare plots around the world at high-spatial and -time resolutions. The researchers used this sample pool of plots to estimate forest cover over the entire planet.

A grand jury has indicted Brett Hankison, one of the Louisville police officers who entered Breonna Taylor's home in March and shot her at least eight times, on three counts of wanton endangerment.

The state of play: None of the three officers involved in the botched drug raid will face charges related to the actual death of Taylor, such as homicide or manslaughter. Two officers were not charged at all.

FDA chief vows agency will not accept political pressure on coronavirus vaccine

Food and Drug Administration Commissioner Stephen Hahn promised that "science will guide our decision" for a coronavirus vaccine at a Senate hearing on Wednesday.

Why it matters: More Americans are expressing doubt about a first-generation vaccine, despite President Trump's efforts to push an unrealistic timeline that conflicts with medical experts in his administration.

CEO confidence rises for the first time in over 2 years

A closely-watched CEO economic confidence index rose for the first time after declining for nine straight quarters, according to a survey of 150 chief executives of the biggest U.S. companies by trade group Business Roundtable.

Why it matters: The index, which still remains at a decade low, reflects corporate America's expectations for sales, hiring and spending — which plummeted amid uncertainty when the pandemic hit.
