A new field study led by University of Illinois researcher Ilsa Kantola demonstrates how we can use rock dust weathering to greatly enhance carbon dioxide removal from the atmosphere. The study was carried out

How to Lock Carbon in the Soil Permanently

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.[4] 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

A Breakthrough in Verifying Carbon Dioxide Removal by Rock Dust Weathering

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 that the chemical breakdown of rocks naturally removes carbon dioxide (CO2) from the atmosphere by converting it into carbonate molecules.

Carbon Drawdown Initiative Advocates New Recipe for ERW Research

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

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

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,

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

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
