American economist Jeffrey Sachs is calling for a global government as the only way to tackle the climate crisis.

He argues that since the atmosphere doesn’t recognize borders, carbon emissions anywhere fuel a global climate emergency.

Sachs insists that no single nation can solve this challenge alone—only a united global authority can.

He clarifies he’s not a globalist in general—only when it comes to confronting climate change.
