As Editor of OneWorld Guides, I'm always coming across uncomfortable predictions about the impact of climate change. Here are just 5 to be thinking about.

1. it will be impossible to grow coffee beans in Uganda if the temperature rises 2 degrees (UNEP)

2. 60% of the Amazon rainforest could become a dry savannah if temperatures continue to rise (WWF)

3. freshwater availability in India will reduce by 30% by 2050 due to retreat of Himalayan glaciers (IPCC)

4. Zambia is heading for a serious food security problem (IUCN) - Zambia contributes 0.006% of global CO2 emissions

5. carbon emissions from deforestation between now and the expiry of the Kyoto Protocol (2012) will exceed emissions related to the entire history of aviation up to the year 2025 (Stern)
