5th Brazilian Congress of Remineralizers Conference

Event: V Congresso Brasileiro de Rochagem Date: July 8 – 11, 2025 Location: Piracicaba, Brazil Host organization: Luiz de Queiroz College of Agriculture, University of Sao Paulo Seminar description: After 15 years of the realization of the 1st Brazilian Congress of Remineralizers, the theme of remineralization gained prominence in Brazil and in the world. Soil remineralizers (REM), are derived from silicate rocks and when properly used, improve soil conditions since they behave as multifunctional inputs (nutrient source, acid neutralization, colloid neoformation). The regulation of this input (Law 12,890 of 2013 and Normative ...

OpenAir CDR Webinar Series explores the science, strategies, and policies of carbon dioxide removal

Event: Carbon Dioxide Removal Webinar Series Date: Webinars in this series will run monthly through March of 2025. Stay tuned for more details on the last two webinars. Location: Remote Host organization: OpenAir Carbon Dioxide Removal Seminar description: As the world navigates the necessary transition away from polluting fuels toward clean energy, most climate scientists acknowledge that we must also remove climate pollution that has already been dumped into the atmosphere. The call for Carbon Dioxide Removal (CDR) grows stronger as new analyses find that the global community is not on track to meet the Paris Agreement targets for ...

Free Online Seminar Series: Enhanced Rock Weathering in agriculture as a natural climate solution

Event: Enhanced Rock Weathering in agriculture as a natural climate solution Date: Weekly on Mondays from 12-1 pm ET from January 27th to April 14th, 2024 Location: Remote Host organization: Yale University Seminar description: Enhanced rock weathering is a process where finely ground silicate and carbonate rocks are spread on agricultural soils. The breakdown of these rocks removes carbon from the air and stores it in soils and soil water, while providing a variety of other crop and soil benefits. While this carbon dioxide removal practice has gained a lot of interest from researchers, industry, and government agencies, the science is ...

Biogeochemical Potential of India to Feed the Nation and Stabilize Climate

Event name: Hybrid Monthly Scientific Meeting of Geological Society of IndiaDate: Wednesday, June 12, 2024Venue: The Office of the Geological Society of India, Bengaluru Watch a recording of the presentation here. Description This meeting featured the presentation "Biogeochemical Potential of India to Feed the Nation and Stabilize Climate" by Dr. Ishfaq Ahmad Mir, Senior Geologist, Geological Survey of India, Bengaluru.

Answering the IPCC Call to Demonstrate Rock Dust’s Potential for Climate Stabilization

The IPCC 2022 report on the impacts of global warming warns that climate hazards will increase dramatically if global temperatures continue rising and exceed 1.5 degrees C above pre-industrial levels.

How to Lock Carbon in the Soil Permanently

Prof. Wolfram Buss of Australian National University 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 define strategies for integrating these methods into agro-ecosystems for large-scale carbon sequestration. Human-induced climate change is already causing severe effects on the environment, ...

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...

Call for Enhanced Weathering Projects for Google’s 2023 Carbon Removal Research Awards

Deadline for applications is April 28, 2023. Apply through their website. Diagram of the enhanced weathering process. In 2020, Google announced its goal to achieve net zero emissions by 2030. Google plans to achieve this target through reducing direct and indirect emissions (scope 1, 2, and 3) by 50% and investing in carbon removal technologies to offset any remaining emissions. As a way to propel technology-based carbon removal solutions forward and meet their own sustainability goals, Google has announced it is accepting proposals for its 2023 Google Carbon Removal Research Awards. Recognizing the need for further research into carbon ...

New UC Davis Center Paves the Way for Rock Dust Research

If the world were to judge soil remineralization based on what could happen, rock dust amendments might already be standard procedure for the world’s farmers. The potential to use rock dust as a carbon storage tactic for climate change mitigation is well known in the scientific community, in addition to its ability to improve agricultural yields and soil health. Benefits like these are enough to make any policymaker or farmer at least consider the use of soil amendment programs, but expectations alone are not adequate to persuade any party to go “all in.” Stakeholders include farmers, ranchers, politicians, business owners, and everyday ...

Barbuda Limestone Soil Crop Growth Stimulated by Montserrat Volcanic Ash

Fig. 1 Principal John Mussington surveying the plants. The plot receiving the volcanic ash on the left, and the control plot on the right. Introduction Soil fertility depends on the geological history of the minerals in it, climate, and their management. Oceanic islands are either limestone or volcanic, the only exception being the high granite islands in the Seychelles, an ancient small continental fragment. Most limestone islands, including all atolls, are low and flat and are much drier than the high wet volcanic islands. Volcanic islands are much more fertile, because they are wetter, and because basalt contains an ideal mixture of the nutrient ...
