UCL Environment Institute How can we deal with uncertain climate change? Twin Approaches What ever we do now, there will still be climate change So we need to 1. Mitigate (reduce our carbon foot-print) 2. Adapt (protect our people)

UCL Environment Institute Example of Gabon Customers obtain: Certainty of carbon stock and carbon stock changes, which are: 1. Assessed and monitored against international standards and procedures, providing – 2. Confidence in the accuracy of the data obtained, underpinned by – 3. Highly reputable expertise from the CAL team based at UCL Gabon Annual Carbon Flux UN REDD+ we need to make a tree worth more standing up and being cut down
UCL Environment Institute Adaptation – aim for 2˚C but plan for 4˚C Adaptation essential to protect the people Science can give broad picture of what the future may hold to design policy
UCL Environment Institute Some thoughts 1.Policy makers need to understand uncertainties in the science so they can make informed decisions 2. Climate change is just one of many problems that must be tackled, but it can make other problems worse 3. Alternative Energy.. essential as development needs power and we must alleviate global poverty 4. Natural resources such as forest need to commodified to finance development 5. Global deal must include Developing countries – can not fail again like Copenhagen
UCL Environment Institute “The poorest and those who have contributed least to climate change will be first affected” Ethics and morals “The carbon footprint of the poorest 1 billion people is around 3% of the world’s total footprint……loss of life will be 500 times greater in Africa”
