Coral adaptation to ocean warming and marine heatwaves will likely be overwhelmed without rapid reductions of global greenhouse gas emissions, according to an international team of scientists.

A new 3D design for electrodes enables the Battolyser™, a battery and electrolyser in one, to store twice the amount of electricity it could previously hold and do so four times faster. Researchers from Delft University of Technology have detailed their findings in the scientific journal Cell Reports Physical Science. The Battolyser now charges and produces hydrogen at a rate comparable to current electrolysers, all without relying on scarce precious metals. This increased capacity saves both space and costs.A new 3D design for electrodes enables the Battolyser™, a battery and electrolyser in one, to store twice the amount of electricity it could previously hold and do so four times faster.

Researchers have quantified for the first time the global emissions of a sulfur gas produced by marine life, revealing it cools the climate more than previously thought, especially over the Southern Ocean.

The study, published in the journal Science Advances, shows that the oceans not only capture and redistribute the sun's heat, but produce gases that make particles with immediate climatic effects, for example through the brightening of clouds that reflect this heat.

A recent study in Nature Communications used data from the NASA and USGS Landsat 8 satellite to identify a major gap in global resilience to climate change: cities in the Global South have far less green space — and therefore less cooling capacity — than cities in the Global North.
