Climate crisis can't be hijacked by global competitions: Justin Vaisse

The war in Ukraine has so fundamentally redirected the course of world affairs that UN Secretary-General António Guterres says little else can be resolved globally before the fighting stops.

That doesn’t stop self-described “eternal optimist” Justin Vaisse from giving it his best shot. The historian took on a mandate from French President Emmanuel Macron in 2017 to organize the Paris Peace Forum, a venue to mend the strained and broken aspects of the multilateral system.


GZERO’s Tony Maciulis caught up with him on the sidelines of the UN General Assembly, where they discussed his plans for the upcoming forum in November, plus his views on Ukraine and bridging ties with the Global South.

Can we use AI to secure the world's digital future?

How do we ensure AI is safe, available to everyone, and enhancing productivity? It’s a big topic at this year’s UN General Assembly. That’s why GZERO’s Global Stage livestream brought together leading experts at the heart of the action for “Live from the United Nations: Securing our Digital Future,” an event produced in partnership between the Complex Risk Analytics Fund, or CRAF’d, and GZERO Media’s Global Stage series, sponsored by Microsoft.

How can artificial intelligence improve everyday life for citizens? Speaking at the United Nations, Parvathaneni Harish highlighted India’s approach to digital public infrastructure. “Today in India, the cost of access to internet is the lowest in the world… and data usage per capita is one of the highest,” he said.

Preparing the workforce for AI

How will artificial intelligence reshape the global workforce, and who will be ready for it? Speaking at the United Nations, Doreen Bogdan-Martin said the rapid growth of AI will transform jobs worldwide, making large-scale workforce training essential. “We’ve seen estimates that 170 million new jobs will be created; maybe 90 million jobs will be lost,” she said. “So how do we ensure that we’re prepared?”

Expanding AI access worldwide

Could AI deepen global inequality or help close the gap? Lisa Monaco, President of Global Affairs, Microsoft, says it all comes down to trust. She argues that “people won’t use technology that they don’t trust,” especially as geopolitical tensions raise concerns about the reliability and resilience of digital infrastructure.

How can we fix the AI divide?

AI is moving fast, but not everyone is moving with it. Inside the UN, global leaders debate how to close the widening AI divide.
Artificial intelligence isn’t just about innovation. It’s about access, infrastructure, and whether the benefits of a transformative technology will be shared or concentrated.
