There is no way to "fight global warming in economically efficient ways".
It probably took 3 to 10+ years for the earth to collect the energy humans burn in a single day by tapping into ancient reserves.
If you want to end global warming, it will likely require an end to the industrial economy & modern civilization (which a large amount of the world's citizens are just fighting now to obtain).
There is not enough energy to continue to create more energy, maintain our infrastructure, manage existing energy debt, invest in new forms of energy (that will not pay off for decades) and grow the economy.
Simply not going to happen. So any side trying to politicize this issue is merely practicing rhetoric.
