Understanding that we face a planetary emergency can help countries and citizens around the world overcome our many interlocking crises, says Sandrine Dixson-Declève, co-president of the Club of Rome during a "C2GTalk" interview. Bringing international, national and local leaders into inclusive, people-focused governance processes can help our emergence into a new type of civilization.

One of the fastest growing—and underreported—subjects in international relations is the rise of private armies. Dr. Sean McFate, Atlantic Council senior fellow and former private military contractor, joins "Doorstep" co-hosts Nick Gvosdev and Tatiana Serafin to discuss his book "The New Rules of War" and how our current paradigm of warfare is obsolete. How can America rethink the trillions of dollars spent on defense? Is the risk of inaction creating a new "Middle Ages"?

It is important to reflect internationally on climate-altering approaches such as Solar Radiation Modification, in case the world is not capable of meeting the mitigation challenge, says Marc Vanheukelen the European External Action Service’s ambassador at large for climate diplomacy during a "C2GTalk" interview. But these approaches should not become an “alibi for inaction.

Context matters and without clarity on the impacts that climate-altering approaches will have from different perspectives, it will be difficult to deal with the ethical and governance dimensions, said Youba Sokona during a "C2GTalk" interview. He highlights the need for research that not only considers the global level, but seeks to understand the national and local levels where people’s lives are impacted.

Waste, from food to plastics, not only affects climate change but also affects people's lives in ways that we don't always consider. Saumya Roy brings these issues to life in her book "Castaway Mountain," which chronicles a community living in Mumbai's vast Deonar garbage mountain. In this podcast, Roy and Carnegie Council Senior Fellows Tatiana Serafin and Nikolas Gvosdev discuss how Mumbai's forgotten community reflects the massive problem of waste around the world.

Will AI systems transform the future battlefield so dramatically that it will render existing paradigms and doctrines obsolete, feeding new intense security dilemmas? In this "Artificial Intelligence & Equality" podcast, Senior Fellow Anja Kaspersen is joined by Kenneth Payne, the author of "I, Warbot: The Dawn of Artificially Intelligent Conflict," to discuss the impact of AI systems on military affairs, the nature and character of war and warfare, strategic culture, and geopolitical affairs.

Finding harmony between man and nature is essential as we tackle the climate crisis, said Professor Pan Jiahua in an interview with "C2GTalk." In this episode, he explores the concept of ecological civilization, and how carbon dioxide removal and solar radiation modification approaches aimed at altering the climate might be considered in this framework.

By 2030, Africa is projected to be home to 60 percent of the world's working-age population. Columbia Journalism School's Professor Howard W. French, author of the recently published "Born in Blackness," joins "Doorstep" co-hosts Nick Gvosdev and Tatiana Serafin to explain how this will impact global economies, climate change politics, and U.S.-China relations. French also calls for a reckoning with history that recognizes the importance of Africa in the global conversation.

Many countries in the ECE region are embracing carbon neutrality recognized as the first milestone towards sustainable energy, with leaders like Canada, Denmark, France, and the United Kingdom, says Olga Algayerova during a "C2GTalk" interview. She calls for countries to recommit to the future: "We are really running out of time and urgent action is needed."

In this episode of the "Artificial Intelligence & Equality Initiative" podcast, Senior Fellow Anja Kaspersen sits down with Gary Marcus, a cognitive scientist, author, and entrepreneur, to discuss the need for an open and healthy scientific discourse on AI. What we can learn from particle physics and CERN to create an international AI mission to make sure this technology becomes a responsible and ethical public good?
