Theme 1 – Earth System Science Modelling

Our Theme 1 programme is being developed across the following three strategic areas to address high-level questions concerning the capacity of rock weathering driven by intensively managed crops to capture carbon and ultimately affect future CO2-climate trajectories, ocean-atmosphere chemistry and marine ecosystems.

Theme 2 – Fundamental Crop Weathering Science

Our Theme 2 programme is utilising world-class controlled environment facilities in Sheffield to elucidate mechanisms and genetic controls on weathering by major warm climate crops (maize and rice) to accelerate the development of new faster weathering varieties that maximise carbon capture and protection against pests and diseases, thus reducing pesticide usage and costs.

Theme 3 – Applied Weathering Science

Our Theme 3 programme is undertaking large-scale field trials to address questions concerning rates of rock weathering in agricultural soils under natural conditions and how feedbacks, e.g., via nutrient release and pH change, may increase food/bioenergy crop productivity and slow soil greenhouse gas emissions.

Theme 4 – Sustainability & Society

Our Theme 4 programme is addressing the real-world feasibility of enhanced weathering through integrated assessment modelling of its environmental and socio-economic impacts, assessment of a global sustainable supply chain capable of carbon capture and storage, and developing a responsible research and innovation framework.

Dr Emily Cox – Guest post: How public attitudes towards CO2 removal differ in the UK and US

Jul 7, 2020

With global greenhouse gas emissions still increasing – and Covid-19 lockdown restrictions merely causing a short-term dip – the challenge of holding global temperature rise to 1.5C above pre-industrial levels is looking ever more formidable.

Achieving this goal looks increasingly unlikely without taking previously emitted CO2 out of the atmosphere – using carbon dioxide removal (CDR) or “negative emissions” techniques.

Dr Maria Val Martin awarded prestigious UKRI Future Leadership Fellowship

Apr 23, 2020

LC3M Senior Scientist, Dr Maria Val Martin, is honoured to be one of four scientists at the University of Sheffield recognised for conducting outstanding research at the forefront of innovation in the UK and awarded a Future Leadership Fellowship by the funding body UK Research & Innovation (UKRI).

Future Leaders Fellowships are prestigious funding schemes that aim to develop a strong supply of talented individuals that are needed to boost research and innovation across the UK.

Maria will use the funding to launch the first UK integrated study into the environmental risks associated with large-scale deployment of land-based strategies to remove CO2 from the atmosphere.

PhD opportunity: ‘Can enhanced weathering provide an effective climate change mitigation strategy?’

Nov 25, 2019

Anthropogenic inputs of carbon dioxide (CO2) to the atmosphere are the primary cause of global warming. New techniques and technologies are urgently required to reduce atmospheric CO2 levels and achieve the Paris Agreement goal of limiting the post-industrialisation increase in global temperature to 1.5°C.

Enhanced Weathering (EW) is a geoengineering strategy proposed to help facilitate this by accelerating the rate of natural chemical rock weathering that regulates Earth’s atmospheric CO2 levels over long (million year) timescales. Although EW has been tested in laboratories and on small scales, its effectiveness at sequestering significant quantities of CO2 over human timescales has yet to be determined. This PhD project will provide important new constraints on the effectiveness of EW for mitigating climate change, through a series of field experiments in the USA and Malaysia.

For more details and how to apply go to: noc.ac.uk. Deadline for applications: 3rd January 2020. Funded by the NERC INSPIRE DTP programme and hosted by the National Oceanography Centre, Southampton, this project will run in conjunction with the Leverhulme Centre for Climate Change Mitigation (LC3M).
