In-depth Notes on Climate Change and Carbon Dioxide Removal Lecture by Dr. Kate Irvin

  • Introduction and Context

    • Acknowledgment of the unceded territories of the Mi'kmaq and Wolastoa peoples and the contributions of African Nova Scotian communities.
    • Introduction of Dr. Kate Irvin, an expert in climate change and mitigation with over 20 years of experience.
    • Dr. Irvin's driving question: Why aren't we acting on climate change given decades of research and knowledge?

  • Overview of the Presentation

    • Title of the talk: "Exploring hope and ethics in climate policy: The case of carbon dioxide removal in uncertain times".
    • Dr. Irvin discusses climate change mitigation and the necessity of addressing this issue.
    • Importance of recognizing the context of carbon dioxide removal (CDR) in discussions about climate change.

  • Current State of Climate Change

    • Record levels of carbon dioxide emissions reached in 2024: 41.6 billion tons.
    • Historical context: Carbon emissions have been increasing since the industrial revolution.
    • Significant events in climate policy:
    • 1987: Brundtland Commission report introduces sustainable development.
    • 1992: UN Conference on Environment and Development, leading to various treaties.
    • 1997: Kyoto Protocol established targets for emissions reductions.
    • 2015: Paris Agreement with targets to keep temperature increases well below 2°C, ideally at 1.5°C.

  • Overshoot and Climate Considerations

    • Definition of overshoot: The likelihood of surpassing temperature goals set by international agreements.
    • Importance of carbon budgeting: Understanding historical carbon emissions and their impacts on future limits.
    • Current estimates suggest we could surpass the 1.5°C target within five years if current emission levels persist.

  • Impacts of Climate Change

    • Recent climate events (e.g., wildfires in NS, flooding in Nigeria) increasing in frequency and severity due to climate change.
    • Disproportionate effects of climate change on communities least responsible for emissions.
    • Ethical implications in climate discussions and policies.

  • Uncertainty in Climate Actions

    • Challenges and uncertainties surrounding climate predictions and the impacts of policy decisions.
    • Eco-anxiety among youth regarding the climate crisis and its future implications.

  • Teaching and Hope in Climate Change

    • Importance of discussing both the challenges and potential solutions in an educational context.
    • The goal is to equip students with the tools to engage critically and effectively with climate issues.
    • Hope is framed not as an outcome but as a process of deep understanding and critical engagement.

  • Introduction to Carbon Dioxide Removal (CDR)

    • Definition: Human activities that capture CO2 from the atmosphere and store it in various reservoirs.
    • CDR as a necessary complement to immediate emissions reductions.
    • Current CDR methods:
    • Nature-based approaches (e.g., reforestation) and more technological methods (e.g., direct air capture).

  • Challenges and Controversies Surrounding CDR

    • Debate on whether CDR may lead to complacency regarding emissions reductions.
    • Need for policy frameworks to ensure CDR is pursued ethically and effectively without mitigating deterrence.
    • Economic implications: High costs associated with CDR technologies and the need for robust financing approaches.

  • Conclusion and Future Considerations

    • Importance of engaging in meaningful discussions and findings within local and global contexts.
    • Encouragement to view CDR as a potential path for responsible action while advocating for urgent emissions reductions.
    • Urgency in finding pathways towards effective climate action that balances technological solutions with ethical considerations and community involvement.
