"Cost in terms of lifestyle" compared to what?
there're studies (e.g. this report from citybank[0]) that shows that inaction is actually more expensive, taking into account the cost of the climate change disasters...
Seems to me that people believe that doing nothing we will keep living in the same way. Sorry to have to wake you up. Doing nothing will screw up the planet and your (and mine) "lifestyle".
The article referenced in this discussion[1] have other nice data/information about this topic.
I have kids and this is not the future I want for them.
