Researchers in Japan have confirmed that microplastics are present in clouds, where they are likely affecting the climate in ways that are not yet fully understood.
In a study published in the journal Environmental Chemistry Letters, Japanese scientists climbed Mount Fuji and Mount Oyama in order to collect water from the mists that shroud the peaks, then applied advanced imaging techniques to the samples to determine their physical and chemical properties.

The team identified nine different types of polymers and one type of rubber in the airborne microplastics, which ranged in size from 7.1 to 94.6 micrometres.
Each litre (0.26 gallon) of cloud water tested contained between 6.7 to 13.9 pieces of the plastics.
“If the issue of ‘plastic air pollution’ is not addressed proactively, climate change and ecological risks may become a reality, causing irreversible and serious environmental damage in the future,” lead author of the research, Hiroshi Okochi of Waseda University, warned in a statement on Wednesday.
When microplastics reach the upper atmosphere and are exposed to ultraviolet radiation from sunlight, they degrade, contributing to greenhouse gasses, Okochi said.
Microplastics – which are defined as plastic particles under 5 millimetres that come from industrial effluent, textiles, synthetic car tires, personal care products and other sources – have already been discovered inside fish, peppering Arctic sea ice, and in the snows on the Pyrenees mountains between France and Spain.
However, the mechanisms of their transport to such varied locations had remained unclear, with research on airborne microplastic transport in particular being limited.
“To the best of our knowledge, this is the first report on airborne microplastics in cloud water,” the authors wrote in their paper.
Waseda University said in a statement on Wednesday that research shows that “microplastics are ingested or inhaled by humans and animals alike and have been detected in multiple organs such as lung, heart, blood, placenta, and faeces”.
“Ten million tons of these plastic bits end up in the ocean, released with the ocean spray, and find their way into the atmosphere. This implies that microplastics may have become an essential component of clouds, contaminating nearly everything we eat and drink via ‘plastic rainfall’”, the university said in announcing the new research findings.
Emerging evidence has linked microplastics to a range of effects on heart and lung health, as well as cancers, in addition to widespread environmental harm.

I heavily emphasize with this, but I must reject it and call it out as the nihilism it is.
Humans have lived in harmony with nature before, we can do so again. We can do it better than before too.
Capitalism is the disease, the primacy of the individual over the collective whole is the plague. If we were unified and dedicated to the collective good we would act differently and achieve different results.
Today, in this context, a single person can achieve great wealth and comfort by fucking the environment, robbing workers, and giving exactly zero shits about externalities that aren’t legislated.
That is the a key component of the locust like behavior those with power engage in.
Just because the present is a fuck, does not mean humanity as a whole is a fuck.
Thank you for coming to my rant.
Capitalism didn’t magically pop into existence from a vacuum, humans created it. You can’t blame the symptom for the disease. Capitalism sucks because humans suck.
I agree that humanity created capitalism and that its nature is a result of the worse impulses of humanity. That does not mean humanity is defined by it. We can be better. As a species we can improve and become better over time. We are a work in progress.
Sadly, we are at a point in time where the worst of us have the power. The mechanisms that determine who has power serve immoral ends. A more democratic society is possible. A truly equal society is possible. People are good for the most part, a societal structure that encourages that aspect of ourselves would elevate us as a whole.
Humans can suck, but we don’t have to.

Although there’s a more positive argument not that people are dumb, but the world is hard. This Freakonomics Podcast episode made me more positive in my interaction with people because most people are just trying to make it through this shitty world and made me more emphatetic to other people.
When did the worst of us not have all the power? Or is this a hopeful hypothetical for the future?
Hope is awful, lowering your expectations of humanity will be a lot less painful for you in the long run.
There have been experiments in a better tomorrow. Cuba, despite the difficulties caused by regressive forces, being a shining example. Their democratic process allows the neighborhood level of social organization to steer the course of the national discussion. It builds upon the core of humanity, our relations to those we live with. I won’t the deny the difficulties caused by the economic siege, but the model itself is rich with potential.
We can better.
Better be quick then. Global fresh water reserves will be 40% over capacity by 2030, and 90% of global top soil and arable land is at risk of depletion by 2050. And that’s not to mention climate collapse and the imminent Blue Ocean Event in the next few years.
Oh, you’re coming from the “it’s too late” perspective. I agree, we are doomed. I still believe it didn’t have to be this way. We have the potential, no matter if it’s realized or not, to be better. We are in for a rough time no matter what at this point.
That turns it into an over-generalization. Not every human wants capitalism, and it’s no more a permanent part of human identity than feudalism was. You’re judging a whole species by the latest 1% of the time they’ve existed, in an inherently unstable social order.
That’s the opposite of what I said, but I can see how it could be read that way.
Humans are inherently shit and any system we create to govern ourselves will devolve into corruption, bigotry and greed, if it doesn’t already start that way.
That was my understanding of your point as well. What about the system we had for 99% of human history? You seem to be drawing this conclusion from “recent” history.
I think you meant “empathize” rather than “emphasize”.
Also - the core problem here is human greed. It’s another example of Tragedy of the commons.
Sorry to squash your optimism but people really are the problem.
Thanks for the correction, and people are malleable. It’s fixable, but yes greed is the issue.
Sadsack nhilists are a plague.
