Heat-tolerant corals may help some reefs persist, but most still erode A recent report on global tipping points warned that coral reefs face widespread dieback and have reached a point from which they cannot recover.

Beyond bleaching: collapse of net coral reef carbonate budgets in the Tropical Eastern Pacific after the fourth global coral bleaching event Abstract. The increasing frequency and severity of marine heatwaves are driving unprecedented ecological changes in coral reefs. Although mass coral bleach

But not all reefs responded the same!!

One reef (Jicaral), maintained coral cover and a positive carbonate budget despite the 2023 heatwave.

Understanding why some reefs show unexpected resilience may help guide strategies to protect coral reefs in a warming ocean.

Mauritius Restores Reefs with Heat-Resistant Coral and Sees 98% Survival Rates While neighboring wild reefs experienced bleaching rates as high as 80%, Dr. Nazurally's reefs experienced just as much in survival rates

Researchers in Mauritius are naturally selecting for and breeding heat resistant corals, which showed 88-98% survival rates after a recent heat wave and bleaching event. #goodnews #coralbleaching

Why corals bleach – Investigation using neutrons from the FRM II Researchers at FRM II have used neutrons to investigate the biological processes behind dangerous coral bleaching in living corals.

Scientists at the Research #NeutronSource Heinz Maier-Leibnitz (FRM II) investigated, for the first time, #coralbleaching processes directly in living corals. 🪸Using #neutrons, they visualized structural changes during bleaching: go.tum.de/326347

Shipping regulations to reduce pollution may have exacerbated Great Barrier Reef bleaching Rising ocean temperatures have been implicated in mass coral bleaching events affecting the Great Barrier Reef (GBR). These events have been increasingly frequent, with major events occurring in 2016, 2017, 2020, 2022, 2024, and 2025. Now, in an unexpected turn of events, it appears that regulations introduced in 2020 to reduce ship fuel pollution may have actually increased the solar radiation that leads to increased coral bleaching, according to a study published in Nature Communications Earth & Environment.

A yellow cylindrical oceanographic instrument suspended by a cable, being retrieved from the sea at sunset. The device is a profiling float, also known as a CTD sensor, used to measure conductivity, temperature, and depth in oceanographic research.

The ocean is a carbon sink, absorbing 90% of the excess heat released from greenhouse gas emissions, leading to cascading effects: marine heatwaves, ocean acidification, ice melting, sea-level rise, habitat loss, and biodiversity decline. #WetTribe #TidetotheOcean #CoralBleaching #OceanAcidification

The Earth Is Nearing an Environmental Tipping Point Today’s global coral bleaching events are the worst kind of climate warning.

This is far more important than Venezuela or the anniversary of the Jan 6th insurrection riot, but they are deeply connected, yet this won’t get the attention it deserves.
