What can I contribute?

It seems to me that there is a big battle on ‘global warming’ and a lot of energy and time can go into commenting and explaining. I am not best placed to do that, but I should put my money where my mouth is. There is no argument for me on this issue for a long time yet I have not done as much as I could personally. How can I expect people who are sceptical or little informed to make changes? I intend to research insulation and heating solutions for my own house and invest in those solutions that I can cope with. I hope to help by example. The investigations and any implementation details and problems will appear on pages here over the next year. First I am looking into solid-wall insulation and loft insulation.
