Conspiracy Theorists Rejoice! Globalists Aim to Eliminate #Contrails During UN Summit
European #climate advocacy group Transport & Environment found that 80 percent of contrail warming is generated by only three percent of flights. The flight rerouting to eliminate that same amount of warming would burn five percent more fuel. The extra fuel might not sound worth it, but reduced contrail warming is 40 times more impactful than the extra #CO2 #emissions.

Apparently these were Eurofighter Typhoons flying overhead just now and not the Isle of Wight launching ICBMs against the upstart northerners over Portsdown Hill as I'd guessed.

I Why yes. I did ask about chemtrails at Senate question period on Wednesday. (Not that I think this puts this absurd conspiracy theory to bed once and for all. But I was happy to do my bit.) https://youtu.be/kG4ahSI4Sao?si=cgxPOEN4-4ymXfz4 #SenateofCanada #Canada #Alberta #ableg #abpoli #chemtrails #contrails #notarealthing #NORAD #UCP

Anyone as a kid ever watch with bated breath as two airplanes with contrails seemed to intersect each other? When the light hits it just right it can be the most fascinating thing in the world. This is one of the few times I caught it on camera: "Crossing in the Sky".

"Aeroplanes that fly at higher altitudes can create longer-lasting vapour trails that are likely to cause more global warming. Since #PrivateJets and modern fuel-efficient jets fly higher than other passenger jets, these aircraft may be causing even more warming than previously thought.

As much as half of the warming effect of #aviation is estimated to be due to #contrails, rather than the carbon dioxide emissions."

"Modern aircraft that fly at above 38,000 feet (about 12km), such as the Airbus A350 and Boeing 787 Airliners, create more #contrails than older passenger-carrying commercial aircraft."

One of a series of photos taken rapidly yesterday morning, when I spotted this airliner on a path which would meant it would get close to the moon, or at least from my viewpoint.

One of the longest #contrails I've ever seen (July 8, 2024)! #contrail #contrailspotting

The United States Air Force Memorial in Arlington, Virginia. Police eventually showed up to make sure I wasn't surveilling the Pentagon. #MemorialDay #AirForce #Arlington #contrails #military #fog

Nothing too remarkable about tonight’s #sunset. I just happen to like the three parallel #contrails. We live under two orthogonal #airways here, one running north-south and the other east-west. The latter is usually busier as it includes transatlantic air traffic.
