Maybe convincing people to cut their energy consumption in half isn't in the cards. At the same time, maybe that is what is needed. The universe doesn't have to cooperate to give us pragmatic solutions.
If the "impossible" solution is required, and the "pragmatic" solution isn't sufficient... why should climate scientists advocate for the latter over the former?
I believe we need to proactively remove atmospheric CO2. Retool our economy and industrial might for that job.
To do that, we need a strong economy.
I'm not saying more, cheaper fossil fuels is a good thing. I just think we should play the cards we're dealt (to ourselves).
But to effectively retool our economy requires a non-CO2 source of abundant power. I am not sure that nuclear as we know it now would fit the bill, because of the various construction and infrastructure costs. Using less is probably more practical then re-inventing nuclear power (iteratively improving nuclear power would still have value).
- with solar capacity doubling every 30 months (1), once our electricity needs are met, we use excess capacity to produce hydrogen.
- we displace most fossil fuel with a combination of biodiesel (algae), cellulosic ethanol, and hydrogen.
- we clean up all our radioactive waste stockpiles, and generate electricity, with traveling wave reactors.
