Climate change: local efforts won't be enough to undo Trump's inaction, study says

Onus still falls on national governments to cut emissions to stave off worst impacts of climate change, Yale researchers say

Individual cities, regions and businesses across the globe are banding together determinedly to confront climate change - but their emissions reductions are relatively small and don't fully compensate for a recalcitrant US under the Trump administration, a new study has found.

A cavalcade of city mayors, regional government representatives and business executives from around the world will convene in San Francisco next month for a major summit touting the role of action beyond national governments to stave off the worst impacts of climate change.
