I suggest that one of the two headings mentioned above should be added to the list of "Topics". There must be a great many users of this website that would like definitive answers to their questions regarding "Global Warming" and not answers from govt. depts. who seem intent on creating a climate of guilt and blame in order to further there own ends.
goodness knows why you think the government is pushing its own agenda over global warming: it's a complicated and expensive business and the government would very much prefer that it wasn't happening. Their vested interest would be in the non-existence of global warming. So why do you think you'd get more definitive answers from anonymous ABers (who might well work for car companies or airlines) than from the government?
