We have had “nuclear peace” since 1945, following the bombing of Hiroshima and Nagasaki. At a time when arms control agreements are quickly unraveling, how to reinforce the guardrails that will deliver a world free of the scourge of nuclear weapons?

A conversation held in Madrid at the Instituto de Empresa—one of Spain's leading universities—focused on some of our most critical global catastrophic risks.

Johns Hopkins University Professor Daniel Deudney compellingly argues that our current nuclear weapons stalemate is neither viable nor stable, putting at great risk our one and only home: spaceship Earth. Why is nuclear arms control and disarmament our only way out?

Climate change will interact in toxic ways with food security and precipitate more frequent episodes of civil unrest and political instability. How can we strengthen the resilience of our food systems to an acceleration of climate change?

There is an urgent need to think imaginatively about changing incentives and channeling financial resources to fund the transition to a renewable energy economy. We are falling short although we have the instruments to do it. Much is at stake if we fail.

We need to evolve from our long tradition of sovereign tribes focused on our narrow interests to the stage when our first loyalty will be to the common global good and to the building of supporting institutions to make this possible.

The European Union is the most important experiment in international economic and political integration. Its experiences highlight key lessons for the rest of the world, at a time of increasing factionalism and multiple threats to democracy.

Russia’s war on Ukraine has intensified the debate about the future of warfare in an age of rapid technological change. Our guest argues that we need to rethink the concept of national security away from unduly militaristic and outdated conceptions.

Our guest argues that there is more at stake in the war than Ukraine's future as an independent nation. The entire architecture of our rules-based global order is in danger of collapse.

Today we face an extremely complex geopolitical environment: to the perils of climate change we must add the global ramifications of the war in Ukraine, rising tensions between the superpowers and the unraveling of our nuclear order.

Powerful insights on why we need to reinforce the crumbling foundations of our global order.

Climate change is the most important and sizable shock to the earth and its ecosystems. Our guest argues that scientists, policymakers and the business community must work together to translate biosphere boundaries into operational targets that create guardrails for the future evolution of the global economy.

Drawing on a lifetime of experience advising governments on tackling corruption our guest addresses some of the critical questions of development, from poverty, education and opportunity to the question of life’s purpose and the development of human potential.

Our response to the challenges of climate change needs a significant boost; we need to do more and move more rapidly if we are to forestall its calamitous consequences. Stockholm+50 later this year will provide a unique opportunity to do so.

The world faces multiple crises. Climate change and the associated temperature rise will interact in noxious ways with biodiversity, pollution, and the global economy. This is no time for incremental change; indifference is not an option.
