The Tephra Bag Citizen Science Experiment: Can use of volcanic ash help to reduce the amount of CO2 in the air?
Tephra is a volcanic ash that has the potential to capture CO2 from the atmosphere in a process called chemical weathering.
This experiment aims to investigate whether tephra could be a potential geological-based solution for climate change by reducing the amount of carbon in the atmosphere.
Working with 5th and 6th class schools across the country we investigatied tephra as a soil amendment. By working with schoolchildren and teachers we explored perceptions of climate change and attitudes towards geoengineering solutions for climate change mitigation.
