Is anyone else wondering if the shutdown for COVID-19 will have a significant impact on carbon emissions? If it does, then it could actually save far more lives than it takes.

Also traffic fatalities.

However with everyone stuck at home all day long there is an increase in domestic accidents and unfortunately also an increase in domestic violence.

> democratic values devils advocate, but if it ends up that democratic states don't handle the response as well as authoritarian ones out of differing views of individual rights, this isn't necessarily a 'win' for the democratic side of the fence

You'd also have to acknowledge that the (Chinese) authoritarian response is what allowed the outbreak to get this bad in the first place. In the United States the Federal response has looked much more like the authoritarian response — no action for regular people, misdirection, profiteering, and grabbing for more power. Compared to the responses we saw under more democratic government against Zika, Ebola, Avian Flu,…

If improper response allows the outbreak to get bad then why are CA, WA, NY having bad outbreaks? Could it be that negative feelings about Trump do not protect from coronavirus?

Centrally generated nuclear power with batteries at the point of use is the safest and cleanest tech that we have. The state of biofuel today leaves a lot to be desired as far as the ability to scale without causing other environmental disasters, and many of them aren't even carbon neutral. As for nuclear cargo ships -- I'd love to see them, but the liability and political hurdles are insane. You'd probably need a re…

Aircraft are only 2% of global CO2 emissions. Generating enough biofuel for just them should be within the realm of possibility. Even without nuclear, container ships don't have major weight restrictions (they already weigh a hundred thousand tons), so you can fuel them with anything that will catch on fire. Make carbon expensive and they'll just buy whatever is the next cheapest -- sawmill residue, seaweed, whatever…

For that matter, all transportation combined is only 24% of greenhouse gas emissions. Tackling utility energy would be a much larger target, and easier to do. Nuclear power works.

Although, burning biomass in ocean-going vessels is not necessarily a net positive. If, for example, they start burning sawmill scraps which were previously being pressed into Ikea furniture, you're just replacing one carbon emission with another. Biofuels are complicated; you have to be careful not to offset sequestration, as well as being cognizant to other emissions generated both in the process of generation and in burning them. Because of the tangential effects, some biofuels emit more carbon than oil!

Why don't you just walk around instead of all that driving?

Around Christmas in Michigan, the temperature hovers around 0C. The person you're replying to is describing about 30 miles of travel, at a rough estimate. So, there's your answer.

I meant walking to some nearby places instead of driving to far-away ones.
