Dr Lennart Bach is an ARC Future Fellow for Climate intervention at the Institute for Marine and Antarctic Studies, at the University of Tasmania. As a Marine Biogeochemist, Lennart has a special interest in marine plankton communities, the carbon cycle, and ocean-based solutions for the climate crisis.

Here Lennart provides a nuanced overview of the ocean-based climate intervention strategies currently being considered.

In this episode we discuss:
• Lennart’s background and his work as a biogeochemist
• Carbon basics in the context of climate change
• The marine carbon cycle, ocean acidification, calcification and what this all means for ocean life
• The complexity of the ocean’s food web and climate change impacts
• The current state of carbon sequestration science
• Climate change and ocean-based solution for removing CO2 – the pros and cons of various strategies
• Opportunity for Tasmanians to become citizen scientists to get involved in Lennart’s research on ocean alkalinity - Citizen Science Project
• The importance of bringing about systemic change to address the climate emergency
