"Shade" is a new documentary film by Shepard Ambellas & Jason Bermas, the descript for which reads: http://shadethemotionpicture.com/ The film has yet to be released, and yet there's enough in the trailer to know that the "chemtrails and geoengineering" segments contain a fair bit of bunk. (Chemtrails segments starts at 1:42) For a more general debunking of chemtrails see ContrailScience.com, but here I'll specifically address the points mentioned in the trailer. Michael J. Murphy: "We now have an issue called Global Dimming" No, we don't. We actually have Global Brightening. The global dimming claims were based on sunlight studies that ended in the 1980s, and the dimming they recorded was due to particulate pollution. Since the introduction of clean air legislation in Western countries this pollution has been greatly reduced, and we now have MORE sunlight reaching the ground in North America than we did 20 years ago. See a full discussion of this here: https://www.metabunk.org/threads/gl...idence-for-geoengineering-or-chemtrails.2182/ With an overview of the academic literature confirming this here: http://journals.ametsoc.org/doi/pdf/10.1175/BAMS-D-11-00074.1 Rosalind Peterson: "This lack of vitamin-D from this man-made cloud cover and these reflective particles, leads to human health problems which are already being identified in the United States. This is false because: As noted above, there has been no such reduction in sunlight, in fact it has increased. The amount of sunlight needed to make vitamin D is tiny, around ten minutes. Vitamin D deficiency is caused by people not going outside, not by low sun levels (which vary vastly by location and time of year) Al DiCicco: "It was very high barium, 190. DiCicco is talking about a blood test for barium. The normal levels of barium in blood are from zero to 400. So 190 is perfectly normal. See the references linked from: https://www.metabunk.org/threads/high-barium-levels-in-blood-mohave-az.128/ Anthony Gucciardi: "Barium is actually the most important as it goes in an not only causes heart disease, which is the number one killer of humans across the board, but it actually disables the immune system function. So does sugar. It's all about the dose. The facts are: Barium is a naturally occurring substance found in small quantities in soil, food, water, and blood. Unusual levels of Barium have not been measured. Al DiCicco: "The reporting limit is 11" The "Reporting Limit" is the reliable limit of detection. If it's below 11 then they can't measure it accurately. On that same sheet that Al is reading from it describes the normal range as being 0 to 489, with 95% of people in the range 1.8 to 165. See: https://www.metabunk.org/threads/the-claims-of-michael-j-murphy-a-factual-examination.172/#post-784 It is unfortunate that many of these claims were debunked over two years ago, and are still being recycled. One would hope this does not reflect the quality fact checking behind the rest of the film.
