Here's an introduction to the members of the House of Commons Science and Technology Select Committee, gleaned from Wiki pages, TheyWorkForYou and so on. For each member, I've given details of constituency, party, educational/professional background and details of their voting records on climate change issues.
The good news is that there are a reasonable number of people there with genuine scientific backgrounds, including a few PhDs and one full professor. In terms of credentials I think this is probably a reasonable group of people to assess the questions that have been asked.
Overall they seem to be much more sceptical of global warming than one might have expected. Intriguingly the distribution of sceptics over the different parties is almost the opposite of what might have been expected, with the Conservatives all appearing to be vigorously green, while their Labour counterparts appear to be the ones who vote against climate change legislation. This could be a case of the Tories trying to establish their environmental credentials as mandated by their party leader, David Cameron.
Here's the list.
Ian Stewart Eccles (Lab). Chemical plant operator. Has voted moderately against laws to stop climate change.
