UN chief says heat is on and we must act now

In a message to the conference in Stockholm, secretary general of the UN Ban Ki-moon sent his best wishes and gratitude to the IPCC, and said the “world’s eyes” are on the city today.

“Since 1990 the IPCC has provided regular, unbiased assessment of the mounting impact of a warming planet.

“You are the world’s authorities on climate change, recognised with a Nobel Peace Prize,” he said, adding: “We need to build resilience and seize the opportunities of a low-carbon future.”
