The annual massive coral spawning of Australia's Great Barrier Reef is underway.

Why it matters: Scientists are concerned that recent severe bleaching at the world’s largest coral reef may limit the size of the phenomenon, the Australian Broadcasting Corporation reports. The health status of the World Heritage-listed ecosystem has worsened from "significant concern" to "critical" for the first time, a new report finds.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.
  • Climate change at the reef is driving ocean warming, acidification and extreme weather, contributing to "dramatic coral decline, and as a result decreasing populations of marine species," notes the report, published by UNESCO advisory body the International Union for Conservation of Nature Wednesday.
  • Professor Terry Hughes, who co-authored a study released in October finding the reef has lost over half of its coral populations in the past three decades because of ocean warming, told the Australian ABC: "Dead corals don't breed."

What to watch: James Cook University researcher Katie Chartrand told the news outlet that she and colleagues have been conducting "large-scale larval seeding using these inflatable nursery systems" and will check on their progress in January.

  • "In favour of corals this year is the La Niña event," she said. "So there is a strong chance that they're going to get a reprieve from [bleaching]."

Over 60,000 koalas killed or harmed by Australia's "black summer" fires

Australia's "'black summer" bushfires killed, wounded or displaced 143 million mammals — including over 61,000 koalas, per a report published Monday

Why it matters: Koalas in New South Wales and Queensland were in "rapid decline" before last summer's fires ravaged the states, per a statement from Dermot O'Gorman, CEO of WWF-Australia, which commissioned the research. It's "a deeply disturbing number for a species already in trouble," he added.

Arizona governor sues Biden administration over COVID funds tied to mandates

Arizona Gov. Doug Ducey (R) filed a lawsuit Friday against the Biden administration for ordering the state to stop allocating federal COVID relief funds to schools that don't comply with public health recommendations such as masking, the Arizona Republic reports.

Why it matters: The Treasury Department said last week that the state would have to pay back the money if Ducey does not redesignate the $173 million programs to ensure they don't "undermine efforts to stop the spread of COVID-19."
