The world’s governments agreed on Saturday to modest steps to combat climate change and to give more money to poor countries, but they put off until next year tough decisions on cutting greenhouse gas emissions.

The deal includes a Green Climate Fund that would give $100 billion a year in aid to poor nations by 2020, measures to protect tropical forests and ways to share clean energy technologies.

Ending a marathon session of talks in the Mexican beach resort of Cancun, almost 200 countries also set a target of limiting a rise in average world temperatures to below 2 degrees Celsius (3.6 F) over pre-industrial times.
