Clouds now contain microscopic pieces of plastic that in turn are causing “plastic rainfall”, according to a new study.

Scientists fear that these particles of less than 5mm - known as microplastics - could be contaminating “nearly everything we eat and drink”.

I believe that this claim is true. The earliest source that I could find was from National Geographic in April 2019. There are numerous other sources, including CNN, Science Direct, Nature Journal, and Wired. Between the consistency of the narratives in these articles, the reputability of the various magazines, and the multi-year chronology of the narrative, this claim appears to be true, and well documented. The Independent is a legitimate magazine, and has a reputation as a fairly credible source. Furthermore, the author, Vishwam Sankaran, has a profile on Linked In that legitimizes their identity as a journalist. Sankaran has more than 500 connections, and a fully documented history of their professional experience as a science journalist. The topic does seem to be well documented prior to this article, but this article focuses on a more recent study which was also documented by the media company Al Jazeera. The only quote that seems questionable is the scientists’ paraphrased belief that they are the first to discover airborne microplastics in the clouds, as the topic appears to have been covered years prior. The writing of the article itself also evokes credibility, as it is not noticeably opinionated, rather documenting the scientific discovery.

This claim is true and has been researched by many environmentalists. The so-called "plastic rain" is a huge concern for our health and the health of all organisms. These microplastics reside in "the free troposphere" and are major pollutants (Sexton). I think it is interesting how this issue may be ignored because these plastics are not seen unless under a microscope in a lab. Therefore people are less likely to remember how concerning it is.

great job for using a lot of reliable sources! I liked how you looked into the author and their LinkedIn as well for credibility. As for questioning the paraphrased opinion, it's good you pointed that out.

This claim and evidence are true and have been tested by many across the globe, one being an example from scientists in eastern China, testing the cloud formation affected by micro-plastics in the air on Mount Tai. They found evidence of fragments where there shouldn't be in the clouds and airflow versus by the land and sea. The details describe in-depth what microplastics are doing to an aspect of our environment and how it could potentially snowball into a much bigger threat. https://www.acs.org/pressroom/presspacs/2023/november/microplastics-found-in-clouds-could-affect-the-weather.html

I liked the way you approached this claim; the information is clear and concise, and you went to extra lengths to fact-check this claim and did a lot of work going "upstream"  to find the LinkedIn of the journalist to legitimize their claims about microplastics in rainfall.

The assertion stands true, and its validity is supported by The Independent, a generally reliable source. Corroborating this information, other reputable news outlets such as Science Daily, Fox, and The Times of India have echoed similar claims, indicating a consensus in reporting. In my quest for further verification, I delved into the origins of The Independent's report and traced it back to a study conducted by scientists at Waseda University in Japan. Professor Hiroshi Okochi and his team at Waseda University were investigating the circulation of airborne microplastics (AMPs) in the biosphere and their adverse impacts on human health and the climate. The study, available on Waseda University's website and published in scientific journals, reveals that microplastics, originating in oceans and entering the atmosphere, may have become integral to clouds, leading to potential contamination of the food and water we consume through 'plastic rainfall.' Cloud water samples collected from Mount Fuji and Mount Oyama confirmed the presence of microplastics, affirming the veracity of the claim that microplastics are indeed found in clouds and rain.

This claim is unfortunately true. According to the Guardian clouds and rain are reported to have microplastics, and evidence of microplastics even extends to blood, soil, and air. Clouds are formed when water condenses and if water contains microplastic so do clouds and rain. Clouds are also accumulating this plastic by trash islands in the ocean.

A quick search shows multiple reputable publications reporting on the study. According to a study done by the American Chemical Society (ACS), in November 2023, Yan Wang and his research team collected 28 samples of liquid from clouds atop Mount Thai in Eastern China. Their findings revealed that low-altitude and denser clouds contain greater amounts of microplastics. Despite the discovery being in China, further research indicates that there are different types of microplastics. Primary microplastics are intentionally manufactured to be small (used for commercial purposes such as cosmetics), while secondary microplastics result from the breakdown of larger plastic items (National Geographic Society). These tiny particles can be carried by the wind and potentially end up in various environments, including clouds, oceans, snow, and rain— even in America. (ACS, "How is it raining plastic?").

https://www.waternewseurope.com/american-survey-reveals-microplastics-in-rainwater-threaten-the-environment/

In this article written in 2019 and posted on National Geographic, it talks about how scientists verified the fact that we had microplastics in our rain water. It writes, “Scientists recorded a daily rate of 365 microplastic particles per square meter falling from the sky in the Pyrenees Mountains in southern France.” The fact is that the micro plastics found were too small for the human eye to see because they were 25 microns and the smallest a human eye has been able to see is 40 microns. So we are not witnessing it but studies have proven to show the microplastics within our air and rain. Another article more recently written in 2023 it talks of a study that during a geological survey in Colorado more than 90% of samples within rain droplets were found to contain microplastics. Nano plastics have proven to adhere themselves to rain forming clouds an is the main source of the rising concern of our potentially “polluted” rain water

This claim is unfortunately true. Microplastics which have been known to be in our environment, specifically aquatic have made their way into other biological/ecological cycles. Multiple other sources cover this, I am not sure why the Independent was the first to be on the case and provide accurate research and information, but CNN and Yale University seem to agree and conform to this truth.

https://www.cnn.com/2019/08/14/health/plastic-rain-colorado-trnd/index.html

https://e360.yale.edu/features/plastic-waste-atmosphere-climate-weather

Both of these sources provide legitimate statistics and offer further explanations as to how this may affect our lifestyles and public health.

This claim, from what I have researched seems to be true. According to the World Economic Forum, a study done by a Utah State University scientist collecting rain water, resulted in 98% of the samples containing micro plastics, which they determined were carried in the air. Further, this claim can be confirmed by CNN Health, in which an article states that scientists at the US Department of the Interior and US Geological Survey, found micro plastics in the rain water using a binocular microscope. There are multiple studies that have been done that claim to have found micro plastics in cloud water, from polymer to rubber, and so on. Below are some links to articles regarding three studies completed on this subject:

While unfortunate, this claim is indeed true. The source you provided, The Independent, is a pretty reliable source of news. To add to this claim there are multiple other outlets saying the same or very similar things. The earliest of these claims that I found comes from Science.org in June 2020. Another more recent article cites a study from Wasdea University, and a USA Today article sites yet another study from scientists in China. That particular study appeared in the Journal Environmental Science & Technology Letters, a publication of the American Chemical Society. The Science.org article says; "no place is safe from plastic pollution. Brahney et al. show that even the most isolated areas in the United States—national parks and national wilderness areas—accumulate microplastic particles after they are transported there by wind and rain."

I believe this claim to be true. The original source by The Independent is a reliable source. On top of reading this article I found a separate article by AsianScientist. Within this article it references the specific study that noted the microplastics within the water and gets into the specifics of the study as well. The study was conducted by researchers at a university in Tokyo and took place at the summit of Mount Oyama in Japan and Mount Fuji. The study and article are both reliable sources. The details and such provided are true. This article and the proof of study then helps the article from the Independent as well.

This claim is true. From my initial research, I looked at the main article tagged in the initial claim and saw that the study's co-author was a scientist named Hiroshi Okochi. I looked up this scientist and found a second article written by Phys.org and published an article that was written by Waseda University which from the previous article I learned was the university where the study was conducted. I then took a quote from that article and found the Waseada University LinkedIn page where they had posted their initial article and findings from the research. This article confirmed the findings that Microplastics tend to be found in precipitation and clouds.

I think that you hav e a very good fact check, the information is very helpful in making a decision about the claim. I think that in the future it is better to include your sources for better credibility.

Yes, this statement is true in fact over 90% of what we eat and drink have some micro plastics in it. Scientists in Japan confirmed 24/28 water samples found particles as well. They even found particles at the top of Mount Tai. Sources such as the Independent and the Guardian both known to be reliable confirmed this information. When scrolling for more information I came across the ACS or American Chemical Society and they said that most of the micro plastics that are ending up in cloud formations come from " highly populated inland areas". This will continue to have a big effect on climate change with this occurring in different areas not just Japan.
