Rock Solid: A scientific review of geological disposal of radioactive waste

En-ligne

By Know Nuclear Waste


The 2025 update of Rock Solid examines the current state of scientific evidence regarding the geological disposal of spent nuclear fuel and other high-level and long-lived radioactive wastes in a deep geological repository (DGR) around 500m underground. Analysis of the existing scientific evidence shows there are many difficulties with the claim that there is a consensus in favour of deep geological disposal. Presentation followed by conversation with author Dr. Helen Wallace.

NOTE THAT THIS SESSION BEGINS AT 12 NOON EASTERN (other sessions begin at 7 pm EST) due to author's location in the United Kingdom.

2026 is bringing a new wave of compliance expectations — and nonprofits are under the microscope. Employment laws are evolving, and one oversight in your policies, contracts, or disciplinary practices could expose your organization to fines, legal claims, or reputational damage.

The Plastics Lifecycle: Implications for climate change

En-ligne

By Collaborative for Heath Environment

Plastics are often treated as a waste problem, but they are fundamentally a health and climate problem. Derived from fossil fuels, plastics contribute to greenhouse gas emissions at every stage of their lifecycle, from extraction and production to use, disposal, and degradation.

The Arctic is uniquely positioned as both a source of petrochemical extraction and an atmospheric sink where plastics and microplastics accumulate, carried by global air and ocean currents. These impacts threaten fragile ecosystems, food systems, and the health of Indigenous and Arctic communities.

This CHE Alaska webinar will explore the deep interconnections between plastics, health, and climate change, with a specific focus on the Arctic. Dr. Leonardo Transande and Rosemary Ahtuangaruak will examine the full lifecycle of plastics, the role of fossil fuel expansion in plastic production, and why the Arctic is on the frontlines of this crisis, incorporating a Just Transition perspective, focusing on what it will take to move away from plastic dependence while protecting workers, communities, and Indigenous rights, and building healthier, more sustainable systems for the future.
