Permafrost erosion reduces carbon sequestration in the oceans

,
A German study shows how permafrost erosion on the coast of the Arctic Ocean leads to an almost 15 per cent decrease in the seawater's ability to store CO2
In some Asian countries, the frequency of flash drought events has increased from 20% to 80%.

Flash drought is becoming increasingly frequent in Asia

,
In some Asian countries, says research, the frequency of sudden drought events has increased from 20 to 80 per cent in just two decades. But the phenomenon is now global

Mixed forests are more prone to carbon sequestration

,
A Chinese study found that mixed forests are able to store a higher amount of carbon due to the greater accumulation of wood debris
Soil respiration, both autotrophic and heterotrophic, is a crucial component of the carbon cycle.

How global warming affects soil respiration

,
A Chinese study makes a new contribution to the issue of soil respiration in the climate change context. Emissions are higher in deciduous forests where the heterotrophic respiration is less prevalent
Support for biochar is part of the Danish government's plan to mitigate CO2 emissions in the agricultural sector between now and 2030. Photo: Lars Plougmann ATTRIBUTION-SHAREALIKE 2.0 GENERIC CC BY-SA 2.0 DeedPhoto: Lars Plougmann ATTRIBUTION-SHAREALIKE 2.0 GENERIC CC BY-SA 2.0 Deed

Denmark bets on biochar for sustainable agriculture

, ,
Biochar in the spotlight: the Danish plan to cut agricultural emissions includes a huge EUR 1.35 billion investment. Chiaramonti (PoliTo): "This solution embraces economic competitiveness and will guarantee multiple benefits"

Marine bacteria may serve as a natural soil fertiliser

,
A Japanese study tested the effectiveness of purple non-sulphur bacteria in providing nutrients to plants. Thanks to their enzymes, these microorganisms take nitrogen from the atmosphere and then incorporate it into proteins
Found in the foams of many products, PFAS are persistent substances in the soil and hard to eliminate.

Australian researchers tested a new method for PFAS decontamination

,
Researchers at the University of New South Wales in Sydney have developed an effective technique to break down the strong carbon-fluorine bonds that make PFAS hard to break do

Permafrost microbes may further accelerate climate change

,
Permafrost microorganisms, explains a study by Colorado State University, are also able to break down polyphenols. A finding that could force an upward correction of CO2 emission previous estimates

In the USA, a predictive model shortens soil test timing

,
Researchers at the University of Arkansas have developed a predictive model of soil structure and organic matter content that halves the overall testing time
In China, the addition of biochar to agricultural soils has generally increased the organic carbon content of soil aggregates.

Here is how biochar promotes the sequestration of organic carbon

,
Biochar promotes the formation of soil aggregates and, with them, carbon sequestration, a research explains. In some Chinese farmland, the presence of the substance has increased by 60 per cent
