Species‐Specific Vulnerability of Northern Red Sea Mesophotic Corals to Accelerated Warming

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Mesophotic reefs are often considered climate refuges, yet experimental thermal‐stress reveals species‐dependent vulnerability. Skeletal optics, energy reserves, and light environment determine bleaching severity. A depth‐generalist coral resisted stress while the mesophotic specialist bleached severely.

Water Consumption in Hydrogen Production Through Electrolysis: Overview, State‐of‐the‐Art, and Future Trends

WIREs Energy and Environment, Volume 15, Issue 2, June 2026.
Commercial‐scale “green” hydrogen projects use renewable electricity to drive electrolysis—the process of splitting water into hydrogen and oxygen. Producing green hydrogen requires water not only for the electrolysis reaction but also for cooling the electrolyzers, which release waste heat.
