The podcast episodes discuss the potential use of marine viruses for carbon capture, as well as the broader context of carbon dioxide removal technologies as a strategy for achieving net-zero emissions and addressing the long-term effects of global warming.

The episodes highlight the need for unconventional climate interventions like CDR, despite the associated risks and governance challenges. They also touch on the IPCC's role in assessing the science and potential of these technologies.

The episodes provide insights into the current state of research and debate around the use of CDR, as well as the ethical and practical considerations involved.
