Apr 1, 2024 · Abstract. Substantial quantities of fine-grained basaltic dust have fallen on South Iceland soils over at least the past 3300 years, making this region an ideal natural analogue to define the long-term consequences of current Enhanced Rock Weathering efforts.
Enhanced Rock Weathering - MIT Climate Portal
Nov 9, 2023 · Enhanced rock weathering is a strategy to help address climate change by taking carbon out of the air and storing it in rocks. It is one of several “carbon removal” techniques that target carbon dioxide (CO 2), the most important climate-warming greenhouse gas humans have been adding to the atmosphere.
Frontiers | Enhanced Weathering Using Basalt Rock Powder: …
This technique aims to accelerate natural weathering, a process that has been responsible for stabilizing climate over geological timescales, which naturally captures 1.1 Gt of CO 2 per year (or ca. 3% of current global CO 2 -emissions; Strefler et al., 2018; Roser and Ritchie, 2020).
Potential CO2 removal from enhanced weathering by ecosystem …
Jul 26, 2021 · Achieving sufficiently high net CO2 removal will require upscaling of basalt mining, deploying systems in remote areas with a low carbon footprint and using energy from low-carbon sources.
