I think the government has realised that the notion of 'climate change' is a nonsense, and spending money on it is a vote-loser, so it has quietly scaled back its payments to the looney-tunes schemes involved.
Mr Gore firmly believes in climate change with the same sort of swivel-eyed zeal that people believe in flying saucers, so naturally he is annoyed at the government's reduction of its spending on this fantasy.
But Mr Gore doesn't have to face election here - the Tory government does.
Pragmatism is a cornerstone of politics.
