No amount of evidence will dissuade a die-hard conspiracy theorist, because any evidence to the contrary is inevitably dismissed as part of a massive cover up. Hey, maybe my dad is part of it as well. While the EPA report concludes, 'contrails pose no direct threat to public health,' it does add: 'Contrail cloudiness might contribute to climate change. Climate change may impact on public health and environmental protection.
What you've seen is an image of a plane filled with water tanks. These flight test ballast barrels are there to simulate passenger weight, and are interconnected so the water can be pumped to different parts of the cabin allowing engineers to assess the planes' performance under a variety of load conditions and different centres of gravity. Twitter Facebook Instagram. National Geographic National Geographic. Is there a worldwide government conspiracy to poison us all by spraying chemicals out of the 15, aircraft crisscrossing the globe at any given moment?
No, almost certainly not. Photograph by Getty Images. Aircraft emissions do, in fact, pose an environmental risk: they contribute significantly to global warming. When I ask Lisa how concern about geoengineering affects her emotionally, she tears up. Nor has it ever been crazy to suggest that politicians and corporations can lie.
Working on the farm, I started to see white hazy streaks in the sky as allegorical shorthand for a host of 21st-century anxieties — about corruption, illness, and looming climate catastrophe and environmental toxins. At Lincoln Hills, that may be the case. Tammi has legitimate reason to fear her crops are exposed to harmful chemicals. I never saw clouds like that as a kid.
The news Tammi has read since January has left her disillusioned. When asked for evidence supporting their convictions, chemtrails believers kept returning to what they themselves had seen. Primary experiences, they suggest, are a more trustworthy gauge of truth than scientific consensus or the mainstream news.
Instead of the news, Rob says he gets his information from friends he respects. Maybe this seemed all in good fun back when conspiracy theories appeared to hold no sway in national politics.
When I explain the focus of this article to Tammi, she expects condescension. Of course, condescension from mainstream institutions only strengthens the impulse to find a sense of power in theories that reject mainstream thinking. While driving me to a scenic overlook where she photographed the sky every few days for a year, Lisa plays a folk song she wrote about geoengineering.
At the overlook, mist hangs in the Ponderosa pines. Across the valley is the faint ridge of the Sutter Buttes. It strikes me that our relationship to facts has become so tenuous that we can literally no longer agree on whether the sky is blue.
Watch your back. I tell her I will be careful, then drive south, not a plane or a cloud in sight. But with a recent study, researchers from the Carnegie Institution for Science hope to put these rumors to rest. The researchers provided the available chemtrail evidence to 77 atmospheric scientists and geochemists for evaluation.
In the study, published in the journal Environmental Research Letters, the scientists were asked if they had ever uncovered possible evidence of a government chemtrail program in their research. Of the 77 scientists, 76 said no. They were also shown photos supposedly containing chemtrails, writes Sara Emerson at Motherboard.
Upon inspection, none of the researchers saw any evidence that the contrails in the photos were any different than normal contrails.
