I’m not aware of any existing technology capable that will mitigate the harm that the current trajectory of the climate disaster is projected to cause.
Hoping for new technology that can save us from the harm 30 year from now is naive. Thirty years ago we had quantum computers, microwaves, GMO, lithium-ion batteries, etc. VTVL rockets are a 25 year old technology already. Hoping for something that doesn’t exist already will save us is simply a disillusion.
In honesty “shutting down the economy” is still a better option then “business as usual”. Although, honestly, I thing there is a better option: Investing in green infrastructure, along with International agreements, and carbon taxes, which we could integrate into existing societal systems to at least slow down the harm until technology is available that can save us from this catastrophe.
Shutting down the economy is not better than business as usual. Business as usual is worse than cost-effective mitigations. Scientists estimate those could cost up to $1 trillion per year, worldwide, by 2030. That’s under 2% of GDP. Damage from climate change in an RCP 8.5 scenario will be many times that, 7-15% in the US by 2100. But it still won’t be nearly as bad as the COVID shutdowns, which wacked 30% off GDP while they were in effect.
> It's worth the U.S. spending hundreds of billions of dollars a year on climate-change mitigation. The EU is planning on spending 260 billion euro annually by 2030. That's roughly the scale of Biden's plan.
I’m not arguing against those investments. My point is that saying climate change will have “untold cost” suggests that massive economic shutdowns or “war time mobilization of the economy” will be worth it to avoid climate change. They won’t be. In particular, anything that jeopardizes economic growth through Green New Deal-style government takeover of vast sectors of the economy will cause more harm than it averts.

I can’t possibly see how reducing (in my opinion) stupid and corrupt business investments and increasing in sustainable infrastructure that will lower our carbon footprint can cause more harm then good. For me this fact is obvious. I think we there must be some fundamental difference between us for us to arrive at such different conclusions.
It advocates a “World War II” style mobilization, of the sort that existed back when the federal government took over almost half the entire economy.
I understand that’s not what you support, but people do support massive efforts like this to combat climate change. My point is simply that when you say climate change will have “untold cost” you make it impossible to understand why the programs you support might be worth it, while a World War II-style mobilization would do more harm than good.
