Contrails are a problem for aviation -- but there could be an easy solution

Many of these studies are complete garbage, as John Ioannidis has demonstrated. I would bet that this study is one of those.

Back in the 70s scientists believed that increased CO2 emissions were going to result in Global Cooling due to solar radiation being reflected back out to space. Now it's the opposite.

Do a Google search for 70s global cooling and see what was being said back then.

Remember, the latest Ice Age ended around 16,000 years ago and the earth has been warming (by the sun) since. https://www.scientificamerican.com/article/what-thawed-the-last-ice-age/

Humans need to look at the earth in terms of Geologic time, not human time. "Geological time is on a different scale from human time. The earth is estimated to be 4.6 billion years old and life is thought to have become dominant on Earth 542 million years ago. The first humans existed around 2 million years ago. This is only a short period of time." https://www.internetgeography.net/topics/geological-time-is-on-a-different-time-from-human-time/

When I saw this is from CNN, I knew it was more Biden/Obama leftist Liberal propaganda

So we need to fly all over the world promoting Contrails as bad!

So let’s reroute the flight and burn more fuel, why don’t we have the passengers pedal the airplane through the sky

The sky is falling... the sky is falling! As usual cnn is on top of protecting us humans from ourselves, to sell more ad space.

It's bad if planes do it but good if environmentalists do it. Startup, Make Sunsets, is releasing particles into the stratosphere (23,000 to 66,000 feet depending on the latitude). Some are concerned.

"Some researchers who have long studied the technology are deeply troubled that the company, Make Sunsets, appears to have moved forward with launches from a site in Mexico without any public engagement or scientific scrutiny. It’s already attempting to sell “cooling credits” for future balloon flights that could carry larger payloads."

No they are not, Contrails are dihydrogen monoxide more commonly know as water, CNN is saying here, that water is bad for the environment. Absolute Trash.
