Important ocean currents that redistribute heat, cold and precipitation between the tropics and the far north Atlantic region will close by 2060 if current greenhouse gas emissions continue. That’s the conclusion based on new calculations from the University of Copenhagen that contradict the latest report from the Intergovernmental Panel on Climate Change. Contrary to what … Read more

Many countries are considering or have already planned to convert lowland agricultural lands into wetlands and thus save carbon dioxide2 emissions. The idea is that oxygen-depleted soils in wetlands emit fewer greenhouse gases than anoxic soils, benefiting the climate. But such transfers can come with a surprisingly high price for the climate, warn biologists from … Read more

From frequent harmful algal blooms – including brown tides – to catastrophic losses of seagrass, fish mortality and extraordinary marine mammal mortality – including the threatened Florida manatee – the Indian River Lagoon suffers from ecological distress. For decades, water managers, policymakers, and environmental activists have considered fertilizer use the major contributing source responsible for … Read more

If, as the saying goes, “nothing in life is free,” corals may pay a price for being so adaptable to climate change. In fact, it was widely believed among scientists that corals should suffer reduced growth or other trade-offs when they partner with symbiotic algae that help them tolerate warmer waters. However, new research led … Read more

Finding clean, sustainable fuels is critical in today’s global energy and climate crisis. Hydrogen is a promising candidate that is becoming increasingly important. However, today’s industrial hydrogen production still contains a significant amount of carbon dioxide2 footprint, especially considering processes such as steam reforming or unsustainable electrolysis. A team led by Professor Dominique Eder of … Read more

Humanity has a long record of making big changes with little thought. From fossil fuels to artificial intelligence, plastics to pesticides, we love inventing our own problems out of the box, only to find that we’ve created different ones. So it can be refreshing to hear about cases where we’ve taken a step back to … Read more

Can surfactants increase the microbiological degradation of oils in North Sea waters? An international research team from the universities of Stuttgart and Tübingen, together with China West Normal University and the University of Georgia, have explored this question and the results reveal the potential for a more efficient and environmentally friendly response to the oil … Read more

Rice University engineers can convert sunlight into hydrogen with record efficiency thanks to a device that combines next-generation halide perovskite semiconductors and electrocatalysts into a single rugged, cost-effective and scalable device. The new technology is an important step forward for clean energy and can serve as a platform for a wide range of chemical reactions … Read more

Roughly 99.9% of fish and shark species are “cold-blooded,” meaning their body tissues generally match the temperature of the water in which they swim—but researchers have just discovered that the great basking shark is one exception in a thousand. Instead, these sharks keep the core regions of their bodies warmer than the water like the … Read more
