While Reconfigurable Intelligent Surfaces (RISs) offer significant wireless communication benefits, this webinar explores their potential downsides. Improper control can lead to accidental harm, such as interfering with adjacent bands, or malicious hijacking, degrading performance. We will discuss the practical implications of these issues.

Speaker: Emil Björnson (KTH Royal Institute of Technology, Sweden). Moderators: Ian F. Akyildiz (Editor-in-Chief, ITU Journal on Future and Evolving Technologies); Alessia Magliarditi (ITU Journal and ITU-T Academia Coordinator, International Telecommunication Union).

This webinar is organized by the ITU Journal on Future and Evolving Technologies (ITU J-FET), a free international journal covering all communications and networking. ITU J-FET welcomes unpublished research and discusses future topics. Find more on the webinar series and Calls for Papers here.

Green colonialism impacts the Indigenous Sámi of northern Europe, with large-scale renewable energy and conservation projects built on ancestral lands without full consent. Wind farms, “green” mineral mining, and hydroelectric dams disrupt traditional livelihoods like reindeer herding. Framed as sustainable, these projects often dispossess Sámi, marginalizing their knowledge, rights, and self-determination for climate action. This issue was investigated by Tristen Taylor, Ingrid Gercama, and Nathalie Bertrams in “Green Colonialism: How New Mines in Sweden Threaten the Sámi.”

Dr. Christine Wörlen, former head of the German Renewable Energy Agency and an independent international consultant, delivered a public talk. Sponsored by the Climate Action Network of Canada, the discussion explored how Nova Scotia can learn from Germany's experience. The central question was: Can the province develop jobs through an eco-economy that grows with the renewable energy revolution?

Pioneers John Elkington, Bjorn Stigson, Doug Miller, and David Suzuki fear climate change issues may worsen before improving. They believe unity and meaningful progress will only occur when daily life disruptions force a realization of the connection between actions and consequences.

This perspective is from one of twenty Ray Anderson Memorial Interviews. These interviews are part of The Regeneration Project, a collaborative initiative by Sustainability and GlobeScan.

Climate change pioneers John Elkington, Bjorn Stigson, Doug Miller, and David Suzuki anticipate worsening conditions before improvement. They fear significant progress remains elusive.

True unity on climate action, they suggest, will only emerge once daily life is disrupted, and individuals fully grasp the direct link between their actions and environmental consequences.

Many believe our current economic model is broken. Pioneers such as Maurice Strong,
