A major global study using teabags as a measuring device shows warming temperatures may reduce the amount of carbon stored in wetlands.

The international team of scientists buried 19,000 bags of green tea and rooibos in 180 wetlands across 28 countries to measure the ability for wetlands to hold carbon in their soil, known as wetland carbon sequestration.

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.

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.

An Osaka Metropolitan University research team has found a way to make more efficient the desorption of water-adsorption polymers used in atmospheric water harvesting and desiccant air conditioning.
