This comment on why the left has fallen head over heels in love with global warming ideology was left on the discussion board by Lord Donoughue. I thought it worth of promotion to a full post.
The issue of why the political left is overwhelmingly supportive of the climate change alarmist ideology/faith, and hence there are relatively few left wing sceptics, is quite complex and would take more space and time than I intend to impose on you here. But may I, as a lifelong Labour supporter, offer a couple of broad observations. They are by no means comprehensive and omit many nuances. But they are major general factors which I have observed in the party for 61 years, and in Parliament for almost 30 years.
