For the last two decades, climate talks, and their top-down multinational approaches, have largely failed to curb rising temperatures. Since then, a number of subnational actors (provinces, cities, businesses, and civil society organizations, among others) have sought to tackle climate change from the bottom up. For example, at a summit in New York last year, various subnational associations pledged to take action to reduce greenhouse gas emissions. Around 75 mayors from around the world, recognizing that cities account for some 70 percent of all greenhouse gas emissions, signed a Mayors Compact to accelerate ongoing efforts to shrink their carbon footprint. And major civil society organizations and businesses also signed various pledges on a range of initiatives, from expanding energy efficiency to halting deforestation.
These initiatives are promising, but they will not do enough. According to at least one study, the subnational initiatives agreed to at last year’s summit have the potential to reduce emissions by only a fifth of the required reduction needed to keep global warming under two degrees Celsius—a threshold that if exceeded, may trigger fiercer storms and increased droughts. Subnational progress is limited because ground-up climate diplomacy has largely operated on an independent track from international diplomacy. The risk with these parallel approaches is that ground-up goals will not be incorporated into top-down ones, which risks marginalizing their efficacy.
Unlocking the potential of subnational climate action will require integration of subnational and international initiatives. And the two entities that can bridge that gap are California and Germany—two of the world’s pioneers when it comes to climate policies.
As we step into 2020, time has come to implement the Paris Agreement and raise climate ambition, but the geopolitical tide seems to be against it. The best way forward at this crucial juncture might be to forge a ‘climate coalition of the willing’ – recognising and streamlining actions of all actors at all levels.
For the first time in the survey’s 10-year outlook, the top five global risks in terms of likelihood are all environmental. They are: extreme weather events, failure of climate change mitigation and adaptation, major natural disasters, major biodiversity loss and ecosystem collapse, and human-made environmental damage and disasters.
Millions of people across Sub-Saharan Africa could face grave hunger in the first half of 2020 because of armed conflict, political instability and climate change-linked disasters, a report says.
The report published by the UN World Food Programme (WFP) this month says that the countries affected will require life-saving food assistance and investment to prevent humanitarian catastrophes.
Australia is currently experiencing one of its worst bushfire seasons, with swathes of the southern and eastern coastal regions having been ablaze for weeks. As the fires have spread, there has been extensive media coverage both nationally and internationally documenting – and debating – their impacts. This Carbon Brief overview summarises how the fires – and the political response to them – have been covered by the media.
