#2I had no idea contrails actually caused that much warming, compared to the exhaust.

#3How much will it cost in fuel (additional miles) and time (flyers’ lives) to reroute?

#4"Why aren’t we doing more to eliminate contrails?"
I'm just having a hard time groking that contrails are really that impacting. TFA just quotes a bunch of numbers, but does not actually discuss how the numbers were derived. Maybe I've just been around too many people into Chemtrails, but this just reads to me as an offshoot of that type of thinking.

> The proposed detours typically result in a 1% shift (and again, this is only for a small percentage of flights). That means increasing fuel use and flight time by around 1%. So if your flight is three hours long, it’s only adding an extra two minutes. For a 10-hour flight, six minutes. This seems socially acceptable to me; most people would barely notice.

It’s funny to me that those people are all essentially a pessimistic flavor of homeopath (in the small quantities can have an effect sense).

#9Very briefly mentioned in the article, but Google worked on this years earlier: https://sites.research.google/gr/contrails/

Likewise. In fact, I was under the opposite impression because of the benefit that sulfur enriched shipping exhaust had for our climate [0]. It looks like these clouds are thinner and don't have the same impact as that, though. While I felt that the featured article linked to their favorite site aggressively (four links to contrails.org), it looks like the google site is legitimate [1]. I couldn't find a recent [2] paper on NoAA about contrails, but presumably others have studied it.
