Former US President Barack Obama has said “most countries have failed” to live up to promises made in the Paris climate agreement.
Obama said the world needs to step up its emission-cutting pledges and work together to limit global temperature rises.
“We have not done nearly enough to address this crisis,” he said.
“We are going to have to do more and whether that happens or not to a large degree is going to depend on you.”
The former president noted that some measures of the agreement have been successful, but the world is nowhere near where it needed to be.
He acknowledged that China and Russia have shown a “dangerous lack of urgency” on climate commitments.
“Most countries have failed to be as ambitious as they need to be.”
