The spiritual grandchild of the Rio Earth Summit agreement of 23 years ago, the universal climate agreement (UCA), is the world's best chance to limit global temperature increase to two degrees Celsius. The universal hope is that it will be adopted at the global climate change summit in Paris, France, in December 2015. The UCA is important because it will record different countries’ commitments to reduce their carbon dioxide emissions, and, this time around, developing countries, too, will make commitments to reduce their emissions—and they are looking for how to fund the actions they will need to take.
How much money is needed by developing countries? Estimates are around US$ 450 billion per year from 2020 on: US$ 350 billion for reduced emissions and US$ 100 billion for adapting to the impacts of climate change. Some of this money will be provided by countries themselves. But to reach their emission reduction targets, a significant fraction will also need to come from developed countries in the form of official climate finance (OCF). These numbers may sound overwhelming, but context is paramount—they should be compared to net inflows of debt and equity into developing countries, which are estimated to be above US$ 1.2 trillion per year.

Although water is an essential input for agriculture and industrial production, it is also scarce in many regions. When it crosses international borders via shared rivers, lakes and aquifers, it can become a source of conflict and contention. Yet while water can be a source of instability, especially in the face of climate change, it can also be a source or catalyst for cooperation and even peace.
The Gulf Cooperation Council’s grid operator is studying the feasibility of a cable to Ethiopia, which would run through currently war-torn Yemen.
Small Island States will be facing dramatically higher adaptation costs to build resilience against the kind of impacts the IPCC projects in its most recent Special Report. Thoriq Imbrahim, former Environment and Energy Minister of the Maldives, urges the international community to attend to the political demands of countries particularly exposed to the impacts of climate change and also confront loss and damage with renewed urgency.
