Climate change is the defining issue of our times. It is also an enormous economic opportunity.

UN Secretary General Ban Ki-Moon stepped up pressure on the richest nations and investors to detail how they will meet a pledge to provide developing nations $100 billion a year for climate-related programs by 2020.

The United Nations will convene a meeting on the issue in New York next month and wants clear commitments on support for the least-developed countries and islands most at risk of being swamped by rising sea levels, Ban said on Wednesday.
