Biography

I am a reader in integrated assessment of climate change at the Tyndall Centre.  My research focuses on the production of policy relevant science related to climate change and sustainability.   A particular focus has been the quantification of the climate change impacts that can be avoided by timely mitigation.  I lead the team that has developed the Community Integrated Assessment System, CIAS, which links together models of the climate system, climate change impacts and the global economy across a range of institutions.  

I am a coordinating lead author of the 5th (2014) assessment of the Intergovernmental Panel on Climate Change, and was lead author of the 4th assessment which was awarded the Nobel Peace prize on 2007.    

My academic background and training is in physics and the natural sciences at Cambridge University.  After completion of my PhD (1989) I pursued my interest in atmospheric sciences and rapidly became involved in policy relevant research, a purpose to which I remain committed today.  Through this commitment I have assisted in national, European and international policy development relating to combating stratospheric ozone depletion, acid deposition, eutrophication, and climate change.

I led the Tyndall Centre’s contribution to HM Treasury’s Stern Review, and continue to lead its contribution to AVOIDing dangerous climate change project for the Dept. of Energy and Climate Change. This has delivered key policy relevant science that informed the UK negotiating position within the UN Framework Convention on Climate Change.

 My former work at the NOAA Environmental Research Laboratories provided evidence on the environmental acceptability of CFC substitutes, leading to inclusion of fluorocarbons in the Kyoto Protocol, winning the NOAA Aeronomy Laboratories Outstanding Scientific Paper Award.  At Imperial College, my integrated modelling work was used in the development of international UN ECE protocols and to underpin the UK’s participation within these.
