There is still hope to save irreplaceable coral ecosystems, but time is running out. Baby corals can ride ocean currents for hundreds of miles, but they can’t outrun climate change. And humans have a limited capacity to make new reefs in cooler waters. buff.ly/nY4jJs0 #WorldOceanDay
Coral reefs face an uncertain recovery from the 4th global mass bleaching event – can climate refuges help?
As baby corals float in the currents, they can expand their species’ range. But can they get to climate refuges fast enough to survive? A new study has good news and bad.

The 2-year ranching rest period after #wildfires on federal land can devastate rural ranching communities. An environmental studies professor says a one-size-fits-all approach may not be needed, as fire impacts vary widely: https://buff.ly/49Hhp9a (Jared L. Talley @boisestate.bsky.social) 🌎
After wildfires, ranchers face 2-year delay to graze cattle on federal land – is it doing more harm than good?
That delay can tip ranchers’ finances into the red. While the land needs time to recover, studies raise questions about whether two years is really necessary.

Wildland firefighters face up to $20,000 pay cut if Congress doesn’t act − that’s taking a toll on a workforce already under stress
Firefighters work long hours to protect communities, often in dangerous conditions and for low starting pay. Surveys show the impact that can have on their physical and mental health.

Since 1970, 63 North Atlantic tropical cyclones (TCs) formed in June for an average of about 1.2 per year. Seventeen years produced 0 TCs in June, and the most was 4 in 2021.
19 of these June TCs remained tropical depressions, and only 7 eventually achieved hurricane status.

The Atlantic hurricane season typically begins June 1 since that's when we start to see sea surface temperatures above 26C (79F), the threshold required for hurricanes to form.
This year, as of May 29, nearly the entire hurricane formation area is already above the threshold (yellow-orange areas).

Given the warmth of recent months, and the current El Niño, 2023 is now virtually certain (>99% likelihood) to become the warmest year ever directly measured.
In addition, 2023 is now very likely (90% chance) to finish at least 1.5 °C (2.7 °F) above our 1850-1900 baseline.
