@urlyman in mitigation I did spend my last 6 years (2009-15) working at DECC trying to improve the UK's response to climate change: I was modelling the UK's energy and emissions and how these could be reduced by policy. Needless to say soon after I retired and with the 2015 Tory election victory the department was abolished and a lot of the good policies initiatives (home insulation, Zero carbon new homes) were then also minimised or postponed.
