Six Months After the Heat Spiked, Caribbean Corals Are Still Reeling – Hakai Magazine
For many Caribbean corals, last year’s heat proved too much to bear. The more time corals spend in hot water, the more likely they are to bleach, turning white as they expel the single-celled algae that live within their tissues. Without these symbiotic algae—and the energy they provide through photosynthesis—bleached corals starve. Survival becomes a struggle, and what had been a healthy thicket of colorful coral can turn into a tangle of skeletons…
Extreme Summer Heat Threatens Coral Replanting Effort – Scientific American

Coral bleaching is now so extreme, scientists had to expand their scale for it – the Washington Post
For more than a decade, marine experts have relied on an alert scale from the National Oceanic and Atmospheric Administration to signal how much stress ocean heat is putting on corals and what risk there is for bleaching. The highest on the two-level system, Bleaching Alert Level 2, has for years represented coral catastrophe. That has sufficed — until last summer…

How much carbon can oysters store? Scientists are trying to find out – Grist
Scientists all along the Atlantic and Gulf coasts are trying to bring oyster populations back, and not just because they’re a popular food. Oysters are also important for healthy coastal ecosystems.

The World Is Running Out of Male Sea Turtles – Science Alert
Green sea turtles are already an endangered species, mainly due to humans hunting them, harvesting their eggs, degrading their habitats, or entangling them in garbage of some kind. But they also face another, more insidious threat from people: the loss of male hatchlings from the species…that this is partly caused by rising temperatures due to climate change – but a new study has now unveiled another human-caused problem driving this trend. Certain pollutants may promote feminization in sea turtles, explains lead author Arthur Barraza, a toxicologist with the Australian Rivers Institute at Griffith University…
