Large-scale carbon sequestration is a significant challenge, especially when considering competition for land and resources among different techniques. In this article we report the findings of Buss et al. concerning the synergistic interactions between techniques and soil processes and how they can enhance carbon sequestration potential. The study aims to identify limitations, assess interactions, and define strategies for integrating these methods into agro-ecosystems for large-scale carbon sequestration.
For over a billion years, rock weathering has played a central role in regulating Earth's climate. So what’s behind the rock-climate connection? It turns out...
In a time of increasing uncertainty about the future, unprecedented fossil fuel consumption, and the frustrating stagnation of deployable green energies, it might seem difficult to imagine a positive future. But those at the Carbon Drawdown Initiative are self-proclaimed “optimists” who see the present period as an opportunity to learn as much as we can and stock our green arsenals for when the time comes that our society is ready for collective change. The Carbon Drawdown Initiative focuses on supporting research, negative emission technology, and public/political ...

According to the Intergovernmental Panel on Climate Change (IPCC), without significant cuts in greenhouse gas emissions, the global temperature will increase by 3 to 4 degrees Celsius by the year 2100. This could have catastrophic consequences for human society. We are already living with the effects of the 1.1-degree increase that has occurred since the ...
Carbon dioxide (CO2) is one of the three main greenhouse gasses causing climate change, which is projected to increase global temperature by 5.7° F by the year 2100. This may not seem like a large change, but the Natural Resources Defense Council warns that it can lead to serious consequences for the planet and humanity, including more severe weather, higher sea levels, crop loss, and more. As a planet, we need to prevent this.
According to Professor Jason Smerdon of Columbia Climate School, the soil and oceans naturally remove CO2 from the air, making them ...

Nickel contamination impacts our crops
By the year 2050, we need to grow 56% more food to feed the projected global population while simultaneously preserving our forests instead of turning them into fields for agriculture. The World Resources Institute has identified five solutions to this problem, one of which is to increase the production capabilities of our existing farmland (Ranganathan et al. 2018). This could be difficult due to nickel, which causes problems in soils ...
Remineralizing the planet increases soils’ ability to produce flora capable of absorbing and storing atmospheric carbon dioxide, thus combating global climate change without resorting to the elimination of hydrocarbons from the energy mix — that is a central theme from David Munson’s Get Real: A Positive Solution to Climate Change.
In his new book, this entrepreneur and inventor also calls for more biochar production and implementation of holistic and regenerative agricultural practices en masse, along with somewhat unorthodox methods for spreading ...

Remineralization proponents really should publish their own research for peer review, moving away from reliance on academic validation to convince policymakers and the public, says Rock Dust Local founder Tom Vanacore.

Agriculture puts a high demand on soil nutrients, with subsequent soil depletion driving the fertilizer industry. Fortunately, silicate rock powder provides a sustainable macronutrient and micronutrient replacement, as explained in a recent literature review by Philipp Swoboda, Thomas F. Döring and Martin Hamer (Swoboda et al. 2022).

For example, silicate rock powders contain most of the nutrients — potassium specifically — that plants require (Deer et al. 2013). This is particularly important in tropical climates due to high depletion of ...
Glacial deposit in Greenland
The EU is the world’s leading exporter of agri-food, supplying 20% of world food and drink (Matthews, 2021; EEA, 2020). In 2020, more than 40% of Europe’s acreage was used for agriculture. 61% of this agricultural area was operated by high to medium intensity farms in terms of fertilizer and pesticide cost. The considerable growth in crop and livestock has caused environmental impacts that call for sustainable solutions.
There are several initiatives currently focused on sustainable agricultural ...
