🌿 Seagrass meadows are vital carbon sinks. But what happens to stored #bluecarbon when seagrass meadows decline? Examining #seagrassmeadows on the coast of Southern China, this new paper delves into the relationship between seagrass decline and #carbonstorage stability, looking at the complex dynamics of sediment organic carbon (SOC). 📉 Observing several species, it was found that declining shoot density, biomass, and coverage was associated with reduced #carbonsequestration stability.  🌍 In light of accelerating seagrass decline worldwide, this research highlights the need for management and protection strategies. By prioritizing the #preservation and #restoration of seagrass meadows, we can enhance their capacity to store carbon and mitigate climate change.

🌍 Crushed Rocks: A Natural Climate Solution? 🌱 A recent study (https://lnkd.in/g_yAuJxV) suggests that spreading crushed basalt on farmland could significantly reduce atmospheric CO2 while improving soil health and increasing crop yields. The research showed that fields treated with basalt captured 10 more metric tons of CO2 per hectare and produced 12–16% higher yields than untreated plots. Other trials worldwide have shown similar benefits. This process, known as Enhanced Rock Weathering (ERW), speeds up the natural breakdown of rocks, pulling CO2 from the air and storing it in ocean water or soil minerals. While ERW requires large-scale mining and transportation, studies suggest it could remove up to 2 billion metric tons of CO2 per year—a major step in combating climate change. With the potential to enhance food security, reduce fertilizer use, and generate carbon credits, ERW is gaining attention as a practical, nature-based solution. Could this be a key piece of our climate strategy? #ClimateAction #CarbonSequestration #SustainableAgriculture #EnhancedWeathering #NatureBasedSolutions

The first high resolution, spatially explicit carbon map of one of the biggest carbon storehouse in North America - the Pacific Coastal Rainforest - is about to be published. Congrats to Trevor A Carter, PhD student w/ me, for doing this amazing and long work. These forests hold 3x the global average (on average), with hotspots going much much higher - despite accounting for 0.3% of global forest area, this forest stores between 0.63% - 1.07% of global aboveground forest carbon as aboveground live tree biomass. A true global treasure. It's a huge area - several Florida's, depending on how you count the complicated ocean-island-fjord mosaic. What this map allows us to do is to estimate the effect of different policies and prioritizations on carbon stocks with unprecedented spatial resolution. In other words, if there's a national policy saying we want to preserve X amount of land, well - now you can pick based not just on streams, or land designation, but also carbon stocks (above and belowground combo coming soon, thanks to soil maps produced by my former postdoc, the illustrious Gavin McNicol who is now at the University of Illinois). Soon to be published in CJFR.

Understanding how forests change is an essential part of determining the amount of carbon that can be stored and sequestered by forests. Different components of forest growth such as mortality and ingrowth need to be quantified to calculate accurate rates of carbon sequestration and net flux. This new post presents a primer on calculating forest growth, from a #ForestCarbon perspective: https://lnkd.in/ehiGSNVs

This shouldn't come as a surprise to anyone working in the (ground-)water sector, but according to researchers from the Max Planck Institute for Biogeochemistry and the Friedrich Schiller University Jena, extreme climate events (heavy rainfall, droughts) disrupt the soil's natural purification capacity and threaten groundwater quality. Intense rainfall can result in rapid infiltration of rainwater into deeper soils, skipping purification processes and transporting pollutants into groundwater. The study found a clear link between groundwater pollution and extreme weather events.

🎓 A new study published in Nature Climate Change last month has improved our understanding of the role of tropical regions in the global carbon balance. 🔥BeZero’s Dr Dave van Wees co-authored this novel research, providing data and expertise on fire emissions to better quantify carbon dynamics in tropical biomass. 🌳 Tropical terrestrial ecosystems contain over half the world’s aboveground live biomass carbon. This study quantifies that between 2010 and 2020, the tropics acted as a net sink, drawing down 0.21 petagram carbon (Pg C) per year. This overall sink function is the result of a gross loss of -1.79 Pg C per year being offset by a gross gain of 2.01 Pg C per year. 🔄 Fire and soil moisture-related factors were identified as main drivers in determining temporal and spatial variability in carbon dynamics. These factors are susceptible to the effects of ongoing climate change, and human influences on fire regimes and vegetation succession, emphasising the need for effective policies and practices in land management. 🔠 Carbon ratings play a critical role in helping funnel finance towards the protection and restoration of tropical ecosystems, supporting their function as a net carbon sink. Our scientific research is advancing global understanding of carbon dynamics, and supports our project-level assessments of carbon accounting and non-permanence risk.

https://lnkd.in/ezE9u7CR Temperatures are rising globally, droughts are increasing and different species of biodiversity are under increasing amount of stress...Why? Because certain gases are getting into the atmosphere in concentrations that disrupt the natural cooling system of the earth...Why? Because these gases acts as "blankets" that keep heat from escaping to outer space... really? Yes: and these are called green house gases. There are many of them but there are 3 mighty ones ...we call them " the big three" Namely: Carbon dioxide, Methane and Nitrous oxide. The most potent (but least noisy) of these fiery gases is Nitrous oxide. 74% of Nitrous oxide emissions come from Agriculture. Yeah...just a prelude to what you'll learn from this article 

#ProtectSoil More than five times the carbon found in all of the world's vegetation combined is stored in soil inorganic carbon (SIC). Solid SIC, which often calcium carbonate has been identified in such large quantities for the first time in a new study. https://lnkd.in/euT64mex

Simultaneous effects of an increasing number of global change stressors on soil C storage and persistence across ecosystems https://lnkd.in/eQXnf893

"The common field crop systems evaluated in this study were sources, not sinks, of atmospheric CO2. Common SOC accounting methods (space-for-time, depth-based, and shallow sampling) obscured the magnitude of SOC losses in these soils, and in the case of space-for-time, suggested SOC gains in rotationally-grazed pastures where more comprehensive methods showed none. While C sequestration in productive, agricultural soils may not be possible, our work aligns with others suggesting that permanently restored and well-managed perennial grasslands are the best options to mitigate agricultural soils’ CO2 emissions." https://lnkd.in/dPe5Y-cp
