"Potholer54" is a (former?) science writer and has done a real good job in fact checking a lot of the nonsense that makes the rounds on the internet.

I am only interested in the science and the facts, and that means checking original documents, e-mails, reports and statements to see if they match the claims. In this video I show which claims stack up and which have been fabricated. Sources were too long to fit into the video description, so I've pinned them in the comments section. DONATIONS: If you'd like to support this channel, please don't send money to me. My videos are free and my channel isn't monetized, so if you'd like to donate and encourage me to spend the time and effort it takes to check all this information, please send money to a charity I endorse, listed in the video description. Thanks. The charity I strongly endorse is called Health in Harmony. It funds a hospital in Borneo that provides affordable health care to villages on the edge of a national park in return for a pledge not to cut down trees. The pledges are monitored, and the result has been a dramatic decrease in deforestation rates and an increase in the health of the local population. Thanks to your generous contributions, the founders are spreading the idea to other countries, like Madagascar. See https://psmag.com/social-justice/save-the-trees-well-save-your-life-46121 for an explanation of their work. You can make a donation by bank transfer here… https://healthinharmony.org/donate/
