AirMiners Panel Engages the Challenge of Verifying Carbon Removal for Enhanced Weathering
Across a landscape, weathering rates can vary widely due to differences in soil. These include properties such as moisture content, soil pH, temperature, soil mineralogy, and vegetative cover. (Credit: John Spencer)
Mary Yap, founder and CEO of Lithos Carbon
In November 2022, a panel of four AirMiners (those working to ‘mine’ atmospheric carbon and stabilize it in the ground) met to discuss the potential of Enhanced Rock Weathering (ERW) and associated challenges for establishing credibility and trust. In short, we need a way to prove that greenhouse gasses ...
The Science of Rock Dust and Carbon Removal with Enhanced Weathering
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 ...
Teaching Bold New Methods: Arina Duvenhage and the Garden of Eden Garden School
Mineral malnutrition is a serious global issue affecting hundreds of millions of people. It is estimated that worldwide, 60% of people are deficient in iron, 30% are deficient in zinc, and approximately 15% are deficient in selenium. Calcium, magnesium, and copper deficiencies are also common in both developed and developing nations. These nutritional deficits result in widespread healthcare problems and diminish the quality of life and community resilience.

OpenAir CDR on Enhanced Rock Weathering: Scaling up climate solutions globally
Dirk Praessler, CEO of Carbon Drawdown Initiative
One of the biggest challenges we face today is climate change. Scientists have long-since warned of the inevitable effects of a warming planet, yet despite this urgency, today’s economy continues to run primarily on fossil fuels.
Decarbonization – the active capture and storage of CO2 from the atmosphere – is one possible solution. However, as Dirk Paessler, founder and CEO of Carbon Drawdown Initiative explained in a recent “Open Air This is CDR” episode, Decarbonization is “pointless without 90% ...
Rockmin Composts Provides Local Solutions to the Global Soil Crisis
According to the Food and Agriculture Organization of the United Nations:
Soils are fundamental to life on Earth but human pressures on soil resources are reaching critical limits. Careful soil management is one essential element of sustainable agriculture and also provides a valuable lever for climate regulation and a pathway for safeguarding ecosystem services and biodiversity
Chris Cameron and his daughter Catriona Dale
In other words, soil degradation is one of humanity's greatest threats. Fortunately, there are experts like the father-daughter team ...
Rock dust can remediate harmful nickel contamination
Researcher from EMBRAPA in Brazil checking on plots testing effects of nickel in soils.
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 ...
Remineralization for a Healthy Planet: RTE’s new white paper
RTE’s latest white paper highlights up-to-date scientific information on remineralization and enhanced rock weathering. Here’s what you can learn.
Researchers, farmers, and climate activists around the world have long-since known about the benefits of soil remineralization and enhanced rock weathering. The results are in and the science is clear: Remineralization techniques can restore, enhance, and maintain soil fertility while capturing carbon dioxide (CO2) from the atmosphere.
Remineralize the Earth (RTE) has recently published a ...
Getting Real: Munson’s New Book Calls For A ‘Positive Solution To Climate Change’
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.
