"Let's stop emissions" is simple but also absolutely impossible CO₂ emissions are byproducts of billions of people using reliable and cheap energy for heat, cold, food, electricity – all the things that make the world a better place

Nordhaus shows that a moderate, increasing, globally coordinated carbon tax can reduce temperatures – optimally by 0.6°C in 2100 down to 3.5°C Policy costs of $20 trillion will still be outweighed by lower climate costs https://doi.org/10.1257/pol.20170046 …

But remember, this is already incredibly challenging (it requires *all* nations to tax all carbon, all at the same pace across the century If not, the policy costs will escalate, making climate policy less effective and possibly net damaging

And Thunberg's solution to "just say no" is not only naive and impossible. Trying to attain it, will incur tens or even hundreds of trillions of dollars of net costs. World Economic Forum is committed to improving the state of the world – and this ain't it

Look up the definition of naive....she is 16. Her solution my be be impossible but it’s not intolerable which 3.5 degrees is.

Dear Natasha, I'm sure we agree one can't just say something is intolerable and wish it away Either you live with 3.5°C Or you have stronger, costlier climate policies and less climate damages Nordhaus' analysis shows that Δpolicy costs outweigh Δavoided climate costs

I couldn't agree more. Are you not arguing we should just ignore climate change? I had the impression that was your argument for some reason. If not, my mistake.
