> The global aviation industry produces around 2% of all human-induced carbon dioxide (CO2) emissions. Aviation is responsible for 12% of CO2 emissions from all transports sources, compared to 74% from road transport. First result on Google...

Aviation has a relatively small global impact because almost nobody can afford to fly. For a typical person in a rich country, it is really easy to double your climate impact by taking a long distance flight per year, for example from Europe to SF.

Fuel price per mile is cheaper in economy than in a Prius. Most poor people don't drive the most efficient cars in market and surely do travel in cars much more than an exec.

The actual process already exists in electrofuels. [0] . If one has enough hear/electricity, they could generate fuel directly usable in existing jet engines with captured CO2, making overall process CO2-neutral [0] https://karmaimpact.com/jet-engine-makers-cast-an-eye-on-nuc...

That is an important step, but unfortunately emissions at cruise altitude have a much higher impact than the CO2 at ground level you produce your fuel from.

How much?

Are these tools really used by disease labs?

Yes. I run an infectious disease modeling lab - while I don't use these tools, I know people who do. In my lab, we use R, Numpy, SciPy, StochPy, etc. You could also just see about donating directly to a lab at a nearby university.

Scary username!

If the quarantine is indeed growing rapidly, that might suggest that Chinese officials are receiving updated information about the scope of the disease that prompts them to expand the quarantine. A growing quarantine seems to suggest they believe the disease is not yet contained.

if you have even a modicum of knowledge of china, you will understand why certain cities were shutdown. saturday is new year's day in china, and thus, thursday and friday are the two busiest travel days of the year. it's like thanksgiving and the related travel in the u.s. but on a whole other level. since wuhan, where the outbreak originated, has a population of around 10 million, the city and two surrounding cities…

Well jeez, excuse me for being wrong. Thank you for the correction.

I would not be surprised by that at all. Every Asia-focused analyst will tell you that the only aspect of China's state-reported numbers you can assume with a high degree of confidence is that they're heavily massaged for PR purposes.

Sometimes it's also possible to draw inferences by observing how the numbers were massaged. For example if you look at the red graph of confirmed cases at [1], there's a very noticeable jump from 1-17 to 1-18. Coincidentally, the third session of the 13th Hubei Provincial People's Congress concluded on January 17. [2] [1] https://3g.dxy.cn/newh5/view/pneumonia [2] http://en.hubei.gov.cn/news/newslist/202001/t20200119…

That jump was explained in details when it happened - test kits were made available shortly before that date. To be more specific, first batch of test kits were delivered to Wuhan on the 16th Jan [1].

Is it safe to assume that if people couldn't fly, they'd drive just as many miles instead? I don't think that's a safe assumption. I think people would visit family less often if it meant a 25 hour drive across the country. They'd probably not vacation on the other side of an ocean either.

What is the best case scenario on how to get this under control?

The best case is hat it doesn't get worse because vaccine production and other treatments scale/improve faster than the virus spreads. It's still hard to predict the pace of either.

We also don't really know what the current scenario is. How bad is it already?
