Climate finance is a fast-growing envelope of international funding, set to reach US$100 billion a year by 2020, and an extra US$100 billion a year thereafter. Halting climate change will require large-scale investment in projects such as renewable energy and forests. The cost of adapting to climate change will also be huge: from coastal defence walls, to irrigation systems, to cyclone-proof housing, extreme and unpredictable weather patterns will require far-reaching changes to our physical environment.
Those billions of dollars that could save and improve lives. But they could also disappear through graft or negligence.
