A community for discussing events around the World

Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

‘Plastic air pollution’: Microplastics in clouds could be exacerbating climate change, study says (www.euronews.com)

The presence of tiny plastics in clouds risks the contamination of ‘everything we eat and drink’, researchers say.

Microplastics have been discovered in clouds, where scientists say they could be contributing to climate change.

Researchers found several types of polymers and rubber in the water in cloud water surrounding Mount Fuji, Japan’s biggest mountain, and Mount Ōyama.

Their study, published in the journal Environmental Chemical Letters, joins a growing body of evidence showing that plastic pollution has infiltrated most ecosystems on Earth.

Fragments of plastic smaller than 5mm (around the size of a sesame seed) have been found in the furthest reaches of the planet and most intimate parts of the human body, including the blood, lungs, and placentas of pregnant women.

"To the best of our knowledge, this study is the first to detect airborne microplastics in cloud water in both the free troposphere and atmospheric boundary layer,” the scientists wrote.

The original post is discussing cloud formation not aerosol concentrations. Clouds can reflect solar energy away from us, but they can also maintain higher temperatures by acting like a blanket. Also, precipitation patterns will change even more rapidly and unpredictably. Again, we need more research on this specific phenomenon. Because it might become problematic.

As is the link I posted, aerosols are the same thing, a suspension of particles

Recent studies reveal that tiny pieces of plastic are constantly lofted into the atmosphere. These particles can travel thousands of miles and affect the formation of clouds, which means they have the potential to impact temperature, rainfall, and even climate change.

Clouds form when water or ice condenses on “seeds” in the air: usually tiny particles of dust, salt, sand, soot, or other material thrown up by burning fossil fuels, forest fires, cooking, or volcanoes. There are plenty of these fine particles, or aerosols, in the skies — a lot more since the Industrial Revolution — and they affect everything from the quality of the air we breath, to the color of sunsets, to the number and type of clouds in our skies.

You originally asked how cloud formation changes the climate and now you're answering your own question?

Whether it heats or cools the earth, it is still changing the climate. Either direction is a dangerous change that can rapidly deteriorate our already precarious situation in regards to climate change.

I don't understand what you're saying by posting these links?

I'm just doing further reading, and finding that it's such a tiny proportion of aerosols that it's likely to have minimal effect.

I like to understand the facts before claiming it's good, bad or neither
