Debunking pseudoscience, myths, and spurious hogwash since 2010.
We are an evidence-based Reddit/Lemmy community dedicated to taking an objective look at questionable theories, dodgy news sources, bold-faced claims, and suspicious studies.
Posting
Title formatting on all posts should be "Debunk This: [main claim]"
Example: "Debunk This: Chemicals in the water are turning the frogs gay."
All posts must include at least one source and one to three specific claims to be debunked, so commenters know exactly what to investigate.
Example: "According to this YouTube video, dihydrogen monoxide turns amphibians homosexual. Is this true? Also, did Albert Einstein really claim this?"
NSFW/NSFL content is not allowed.
Commenting
Always try to back up your comments with linked sources. Just saying "this is untrue" isn't all that helpful without facts to support it.
Standard community rules apply regarding spam, self-promotion, personal attacks and hate speech, etc.

- offshore wind farms pose a severe threat to aquatic life
The issue is the "severe" portion. Running wind farms do cause noise, but it's 10 to 100 times less than from ships. So it's unlikely to be much of a change.
The construction (pile driving) is more problematic, but you can mitigate that with bubble walls. .
Good point, and thanks for the source!
NJ.com look into this (https://archive.is/3ysCV). For (1) 6 is not an unprecedented number of whale deaths as there have been a few whale deaths every year in that region for the last 20 years. NOAA is investing sudden increase in whale deaths since 2016, but states that "so far no humpback whale deaths have been attributed to offshore wind activities".
For (2), from my understanding building offshore wind farm causes some local disturbance to aquatic life due to the construction works. But it's fairly limited in time and space. Compared to for example ocean deoxygenation resulting from i.a. climate change, construction of offshore wind farms that try to help deal with climate change is a minor threat to aquatic life.
It is plausible. Some (possibly most) whales use sound (low quality sonar) to figure out where the shore is. Most food is within a few miles of shore (unless ocean currents push or heat the food at the bottom in a certain way in some oceans where there is tones of food in the ocean for miles.
Regarding this specific claim, if there were to be large masses that react to sonar (wind farms) that are in a grid, it could seem like a "shoreline" to a whale, and it could confuse the whale enough to beach while trying to find food, a mate, or a place in the ocean to rest and breathe. However, with the given information there is no conclusion other than "there might be a correlation" without more data.
In contrast, certain costal military bases have submarines that accelerate so fast that the propellers cause cavitation (sudden phase change of water from liquid to gas from low pressure). These submarine's cavitations & related cavitation collapses creates a kind of "turbulence" underwater but it sounds MUCH MUCH worse. Whales have been distressed in those areas for a while and after a generation or so, only the adolescents or "foreigner" whales get confused enough to beach anymore. Again, there is not enough information to have a conclusion other than "I think this is a correlation, we weren't tracking that before, but it seems to explain what we are observing".
