> This is the same as my committing to start my diet, by giving up one specific thing, but not for a decade, after my doctor told me I gave 6m to lose weight or die. And to celebrate I'll eat two pizzas and 4 litres of soda, for breakfast.

Great analogy. But to be honest politicians don't make drastic changes as they fear they will loose the next election.

But I do believe they under estimate people's interest in dealing with climate change.

Then again Brexit happened and people vote for Boris and Trump so what do I really know what the electorate wants.
