I am a climate and weather scientist, currently working as “Head of science” in the Technical Support Unit (TSU) of the Intergovernmental Panel on Climate Change (IPCC) Working Group 1. The IPCC is the leading international body for the assessment of climate change. It was established by the United Nations in 1988 to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socio-economic impacts. Previously, I worked as “Climate science expert” at the African Climate Policy Centre (ACPC) of the United Nations Economic Commission for Africa (ECA) – in charge of provision of climate information, its translation and packaging and dissemination across Africa to support decision making across key development sectors (energy, infrastructures, water, food security agriculture) in the framework of the ClimDev-Africa programme.
