Currently, pelagic Sargassum seaweed blooms represent a near-global ecological disaster. The purpose of the present study is to point to evidence that aerosolized coal fly ash is the “smoking gun”, a major, if not the major, causal-factor underlying the Global Sargassum Crisis. At least as far back as the 1990s, concerned citizens had started to notice white trails, often called “chemtrails” that stretched across the sky ultimately becoming a white haze. As time passed these became more frequent and were observed over wider geographic regions. Published elemental data of pelagic Sargassum samples, as ratios relative to barium, are largely consistent with the range of corresponding element ratios from European and American coal fly ash samples, providing evidence of Sargassum incorporation of matter from aerosolized coal fly ash. We obtained a proxy for the unavailable relative annual amount of geoengineering aerosolized coal fly ash by using the annual occurrence of the word “chemtrail” in Google Books. The striking increase in that proxy for relative annual change in chemtrail activity parallels the formation of the Great Atlantic Sargassum Belt beginning circa 2011. Moreover, cited experimental data provide direct evidence that coal fly ash acts as a nutrient and fertilizer for bacteria and cyanobacteria. Both symbiotic heterotrophic, diazotrophic (nitrogen-fixing) cyanobacteria and bacteria located within Sargassum biofilm require ample iron because the nitrogenase enzyme complex requires large amounts of this element to fix nitrogen. The solution for halting, or at least profoundly reducing, the current Global Sargassum Crisis is simple: End atmospheric contamination by aerosolized coal fly ash. Cease coal fly ash use for geoengineering, and sequester all coal fly ash from smokestack exhaust. Were this to be done, not only would the Global Sargassum Crisis subside, but global warming would subside and stratospheric ozone depletion would subside. Moreover, human and environmental health would markedly improve.
