I think the confusion arises from the difference between the words "collectivist" and "collective". Collectivism is the name of a political philosophy closely related to socialism communism, and a term popular with libertarians. In this context, writing "collectivist attempt to fix it" reads like 1) a suggestion that the British Empire's actions were motivated by a collectivist government and 2) that you're trying to tie failure to tackle global warming into a larger libertarian worldview. I think it's a valid argument that collective action for long term gain against short-term self interest is very difficult to achieve.
