Harvard's Dan Schrag, Director of the Harvard University Center for the Environment and Member of President Obama's Advisory Council for Science and Technology, is the co-author of this major international report on the risks of climate change. 

The report presents a climate change risk assessment that aims to be holistic, and to be useful to anyone who is interested in understanding the overall scale of the problem. It considers:

  • What we are doing to the climate: the future trajectory of global greenhouse gas emissions;
  • How the climate may change, and what that could do to us – the ‘direct risks’ arising from the climate’s response to emissions;
  • What, in the context of a changing climate, we might do to each other – the ‘systemic risks’ arising from the interaction of climate change with systems of trade, governance and security;
  • How to value the risks; and
  • How to reduce the risks – the elements of a proportionate response.
