denialist
I love that word.
I didn't know that about the PP. The issue is that the People's party is undermined by Liberals. Take for instance the case of Barroso, when he joined the portuguese liberal party (PSD) it belong to the European Liberal group; somewhere during the turning of the century they simply left and joined the conservatives, in so doing gaining practical grip on the Parliament.
And before you know it, a man that started his carer in the Communist Workers party is head of the Commission backed by Conservative Europe :-)
The debate on Anthropogenic Global Warming shouldn't be a plitical option, like every scientific issue. Vencit omnia veritas.
