It is a great honour and pleasure for me to speak a few words at this historic occasion of launching the synthesis report of the Fifth Assessment of the IPCC [Intergovernmental Panel on Climate Change].
We are doing this at a very historic and crucially important timing for humanity.
Sound science must be at the core of our efforts to meet the challenge of climate change.
For more than a quarter century, the IPCC has been at the forefront of increasing understanding about this issue, climate change.
