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

(CNN) — On a clear day, with the right weather conditions, a portion of the sky busy with commercial flights can become riddled with contrails, the wispy ice clouds that form as jet aircraft fly by. They might look innocuous, but they're not -- contrails are surprisingly bad for the environment. A study that looked at aviation's contribution to climate change between 2000 and 2018 concluded that contrails create 57% of the sector's warming impact, significantly more than the CO2… ( More...

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.

Water vapor accounts for about 60% of the Earth’s greenhouse warming effect

If contrails caused anything at all it would be additional cooling due to blocking sunlight from heating the surface but it is so negligible as to be beyond worry. As far as preventing heat from leaving the surface, that would simply make up for minutely blocking sunlight and therefore preserving the balance of nature. Of course, chicken littles need something to be terrified of so here we are.

So if we get rid of all the water, we will save the world! There are problems that just can't be solved and this is one of them! Every group comes up with something that is doom and gloom and is going to kill the world.. Some years back is was Cows Farting... If we get rid of everything thing kills us, what will be be dying of... They get rid coal because it pollutes, so they bring out Solar Farms (That are Hazmat and cannot be recycled), we are going to be saved by Wind Power (Whose blades cannot be recycle and fill up our land fields and they are killing birds and the ones off coast are now killing whales). I know I am being sarcastic... But somethings are just to stupid not to have fun with...

It's not like you have any integrity. Your entire posting career is devoted to propaganda.

May as well call them Chem trails, lol. Sorry, couldn't help myself.

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."

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

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.

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."
