As ocean temperatures rise, corals' ability to withstand and adapt to heat stress is critical for the future of coral reefs.
Coastal blue carbon ecosystems--mangroves, salt marshes, and seagrasses--store carbon and protect shorelines, but conservation often lags behind rapid coastal change. This study introduces a dual-constraint spatial planning framework that couples habitat suitability with land-sea anthropogenic pressures to identify where these ecosystems can persist, expand, or be restored. Applying it across China's 18,000-km coastline, researchers integrated 60 environmental variables and 13 pressure indicators to map potential suitable distribution areas and optimize protection priorities. The framework reveals a proactive blue carbon expansion capacity 7 to 24 times larger than current extents. It also shows that existing reserves cover only about 20% of high-priority zones, leaving most target areas dependent on active restoration.
Satellite L-band radiometry has transformed open-ocean salinity monitoring, but coastal retrieval remains difficult. Bright land signals leak into ocean measurements, while side lobes, imaging artifacts, radio frequency interference, and calibration errors distort brightness temperature near shore. Existing forward models also assume fully developed, wind-driven seas and often neglect fetch limits, wave age, shallow-water effects, and wave–current interactions.
Bushfire smoke is affecting Queensland urban air quality more often and more severely than previously understood, with new QUT-led research revealing bushfire-impacted hours have almost tripled in recent years, increasing health risks for communities.
In a new study published in Nature, Saint Louis University School of Medicine researchers reveal an entirely unexpected blueprint for how one of the oldest microbes on Earth processes nitrogen to create ammonia, the building block of fertilizer.
Seaweed aquaculture is a nature-based climate solution. Macroalgae contribute roughly 1.5 petagrams of carbon (PgC) to global annual net primary production, and farm sediments can bury about 1.87 ± 0.73 tons of carbon dioxide equivalent (CO2e) per hectare per year—about twice the rate of adjacent non-farmed areas.
Curtin University and Taronga Conservation Society Australia researchers have conducted the first hearing tests on Australian sea lions and long-nosed fur seals, revealing what sounds these marine mammals can hear and helping assess how human-made noise could affect them.
For decades, scientists have regarded phosphorus as the main nutrient limiting biological production in the Gulf of Bothnia. Now, a new study led by researchers at Umea University shows that a fundamental change is underway. The Bothnian Sea has shifted to nitrogen limitation, while the Bothnian Bay is rapidly moving in the same direction.
Researchers from the Faculty of Sport and Health Sciences at the University of Jyväskylä, Finland, found that biological ageing may accelerate already in early adulthood.
Aurelien Acquier, Professor at ESCP, and Jozef Cossey, Assistant Professor at ESCP, have unveiled the findings of a year-long study on corporate climate strategies: specifically, businesses' preparedness and resilience in a warming world.
