@Sandra I mostly agree. But by what mechanism will you build the political power necessary to end capitalism, and take other drastic action to save civilization & the biosphere?
You seem to argue a narrow focus is necessary, only fix GHG emissions. But CFCs only affected fridges/AC, Y2K only computers (before everything was computers).
Successfully addressing the climate crisis requires changing almost everything about our culture. A broad coalition is required to mobilize all of society.
