Mixed forest regeneration optimises carbon sequestration

,
An American study quantifies the efficiency of different forest regeneration methods. By applying the most cost-effective system for each location, around 10 billion tonnes more CO2 can be sequestered at the same cost
The rate of permafrost erosion could even triple by the end of the century, thus impacting the climate. Photo: Brandt Meixell, USGS CC0 1.0 Universal CC0 1.0 DeedBrandt Meixell, USGS CC0 1.0 Universal CC0 1.0 Deed

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
Due to their carbon sequestration potential, forests are an essential resource in climate change mitigation. Photo: USDA Nicholas A Toneli Creative Commons; Attribution 2.0 Generic (CC BY 2.0)USDA Nicholas A Toneli Creative Commons; Attribution 2.0 Generic (CC BY 2.0)

Forests still offset half of global fossil emissions

,
The world's forests, an American study notes, absorb between 3.5 and 4 billion tonnes of carbon each year. Equivalent to "nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019."

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"
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 thawing awakens microbes that process organic matter, producing greenhouse gas emissions. Photo: NPS Climate Change Response PUBLIC DOMAIN MARK 1.0 UNIVERSAL PDM 1.0 DeedNPS Climate Change Response PUBLIC DOMAIN MARK 1.0 UNIVERSAL PDM 1.0 Deed

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 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
The researchers' hope is that by predicting drought in advance, farmers and ranchers can better plan for water management. Photo: jackoscage CC BY 2.0 DEED Attribution 2.0 Genericjackoscage CC BY 2.0 DEED Attribution 2.0 Generic

NASA follows the light and anticipates flash droughts

,
Space Agency researchers have found a correlation between flash drought and the intensity of induced fluorescence. A phenomenon related to photosynthesis and observable from space
