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
Globally, scientists explained, wetlands are rich in biodiversity and provide various services including water supply for agricultural use and carbon storage.

Here is how the climate will affect the wetlands in North America

,
Wetlands, a study from the US explains, will experience substantial drying during the summer. Impacting habitat and biodiversity from Florida to Mississippi to southeastern Canada
Answers to questions about past and future erosion could be found in the fossil sediments of the Pyrenees. Photo: NASA public domainPhoto: NASA public domain

Answers to questions on climate and erosion are 56 million years old

,
A study by the University of Geneva revealed how erosion in the Pyrenees increased 4-fold during the global warming experienced between the end of the Palaeocene and the beginning of the Eocene. A scenario that could now be repeated

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"
Driven by climate and agricultural activities, the greatest soil loss in the United States has occurred mainly in the Central Great Plains, on slopes and in cultivated soils.

How climate and human activities have eroded the US soil

,
Climate and land-use change have promoted erosion in the United States over the past 70 years. The Central Great Plains has experienced the most significant loss
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

Mixed forests are less vulnerable to soil acidification

,
The Chinese study: in larch and broad-leaf forests, nitrogen deposition has no significant impact on soil chemistry. Therefore, in the fight against acidification, the creation of mixed forests could be effective
