U.S. envoy says climate summit can yield 'enormous progress'

U.S. climate envoy John Kerry said Saturday he thinks 'enormous progress' can be made at upcoming UN climate talks in Scotland but more governments must come up with concrete commitments in the next 30 days.

Kerry attended a preparatory meeting in Milan where delegates from around the world sought to identify where progress can be made before the UN Climate Change Conference of the Parties starts in Glasgow on Oct. 31.

The 12-day summit aims to secure more ambitious commitments to limit global warming to well below 2 degrees Celsius with a goal of keeping it to 1.5 degrees Celsius compared to pre-industrial levels.

The event also is focused on mobilizing financing and protecting vulnerable communities and natural habitats.

"The bottom line is, folks, as we stand here today, we believe we can make enormous progress in Glasgow, moving rapidly towards the new goals that the science is telling us we must achieve," Kerry said.
