Roots and A.I. offer carbon storage solutions

,
According to Alliance of Bioversity International deeper roots boost carbon sequestration while artificial intelligence enables more accurate measurements of carbon storage
The reviewed projects affect 3.4 million hectares of land in the interior drylands of Queensland, New South Wales and Western Australia where forest cover has increased by just 0.8 percent.

Forest regeneration in Australia does not influence CO2 sequestration

,
A study shows that restoration projects implemented in Australia have had a negligible impact on tree cover. A finding that openly questions the effectiveness of the national carbon market

Microbes are a key resource for slowing desertification

,
Chinese investigation shows how microbes play a relevant role in countering desertification through their ability to manage essential soil nutrients
Cyanobacteria, or blue-green algae, have a high iron content and can be used to produce biological fertilizers. Photo: Josef Reischig CC BY-SA 3.0 DEED Attribution-ShareAlike 3.0 UnportedJosef Reischig CC BY-SA 3.0 DEED Attribution-ShareAlike 3.0 Unported

Cyanobacteria are amazing biofertilizers for soil

,
According to a U.S. study, cyanobacteria or "blue-green algae" can be used to produce a biofertilizer suitable for iron-poor soils, thus turning into a valuable natural resource for farmers

Drainage channels in peatlands produce significant emissions

In Southeast Asian peatlands, man-made channels to drain soil contribute to carbon leakage into the atmosphere, research says

In peatlands, climate change supports the degradation of organic carbon

,
An experiment shows that in peatlands all organic soil components decompose more rapidly when temperatures are higher
The effects of soil desiccation cracking promoted by drought are an example of the feedback loop between climate change and soil. Photo: Christopher Michel CC BY 2.0 DEED Attribution 2.0 GenericChristopher Michel CC BY 2.0 DEED Attribution 2.0 Generic

Soil releases more GHGs than expected as drought plays a crucial role

,
A U.S. study hypothesizes the existence of an "amplifying cycle" involving drought, soil desiccation and CO2 emissions. A mechanism that climate models do not seem to take into account
Per comprendere l’effetto del clima sui microbi i ricercatori hanno esaminato una prateria subartica in Islanda soggetta, da oltre mezzo secolo, al riscaldamento geotermico. Foto: Christina Kaiser Universität Wien Press ReleaseChristina Kaiser Universität Wien Press Release

Diversity of soil microbes increases with climate change

,
A study from the University of Vienna brings new insights into the microbiome-climate cycle in the soil. Higher temperatures activate dormant bacteria, scientists explain

Soil moisture rises despite climate change

,
Precipitation, not temperature, explains soil moisture trends, a Harvard University study has found. It is critical to improve forecasts of long-term changes in rainfall in response to climate change

Lack of data from Russia puts Arctic climate study at risk

,
After the invasion of Ukraine, communications between Arctic stations in Russia and those located in Western countries broke down. And not without consequences, says a Danish study
