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.

At the conclusion of the 50th Pacific Islands Forum, Pacific leaders issued a Forum Communiqué and the ‘Kainaki II Declaration for Urgent Climate Change Action Now’ – the strongest collective statement the Forum has issued on climate change. Pacific leaders highlight the UN Secretary-General’s Climate Action Summit, the SAMOA Pathway Review, and 25th session of the Conference of the Parties (COP 25) to the UNFCCC as “global turning points to ensure meaningful, measurable and effective climate change action”.

If ratified, the Mercosur-EU trade deal may reinforce the parties’ commitment to climate action. Yet, its potential relevance is weakened by a language that often stops short of concrete commitments, as well as political resistance.

Iraq is on the verge of an environmental breakdown, and climate change is not helping. The country's fragile environment and the increasing scarcity of natural resources — particularly water — are a result of poor environmental management, as well as several political and historical factors. However, as climate change impacts add to the existing pressures, the environmental collapse turns into a security issue.
