Though I've posted on this subject before, I thought that this report prepared by the UK House of Lords Economic Affairs Select Committee is really worth looking at:
http://www.publications.parliament.uk/pa/ld200506/ldselect/ldeconaf/12/12i.pdf
It drew on evidence provided by a large number of experts, along with academic/research institutions and businesses:
Professor Dennis Anderson (Imperial College, London), Dr Terry Barker (Cambridge University), Mr Christopher Beauman, (former adviser, Cabinet Office), BP, Dr Leonard Brookes (Fellow of the Energy Institute), Sir Ian Byatt, Dr Ian Castles (Australian National University, Canberra), CSERGE (the Centre for Social and Economic Research on the Global Environment), Department for Environment, Food and Rural Affairs (Defra), Professor Paul Ekins (Policy Studies Institute), George C Marshall Institute (Washington DC), Dr Indur M Goklany, Professor Michael Grubb (Imperial College, London), Dr Dieter Helm (New College, Oxford), Dr Cameron Hepburn (St High’s College, University of Oxford), Professor David Henderson (Westminster Business School), Mr David Holland, MIEE, Dr Chris Hope (University of Cambridge), Sir John Houghton, International Council for Capital Formation (ICCF), International Policy Network, Sir David King (Chief Scientific Adviser to the UK Government), Professor Richard Lindzen (Massachusetts Institute of Technology), Professor Bjorn Lomborg (University of Aarhus), Professor Angus Maddison, Dr David Maddison (University College London), Professor Ross McKitrick (University of Guelph, Canada), Professor Robert Mendelsohn (Yale University), Professor Nils-Axel Morner (Stockholm University), Professor Julian Morris (University of Buckingham), Professor Nebojsa Nakicenovic (IIASA and Vienna University), Dr R Pachauri (Chairman, IPCC), Dr Peter Read, Professor Paul Reiter (Institut Pasteur, Paris), Research Councils UK, Professor Colin Robinson (University of Surrey), Ms Rosemary Righter (The Times newspaper), The Royal Society, Professor S Fred Singer (University of Virginia), Professor Richard Tol (University of Hamburg), Mr Paul Johnson (HM Treasury), Mr Adair Turner (Tyndall Centre for Climate Change Research).
All of their written and oral evidence (including the questions posed by the committee) is available here:

I found this a good resource because, with regards to the climate change debate, the witnesses effectively cover the full scientific and economic spectrum.
The 'hockey-stick' temperature study - talked about in this report - has recently been scrutinised by the US House of Representatives Committee on Energy and Commerce:
