Harvard University on Chemtrails aka Solar Radiation Management (Published Study- Harvard)

Sharing is Caring!

Public Understanding of Solar Radiation Management



We report the results of the first large-scale international survey of public perception of geoengineering and solar radiation management (SRM). Our sample of 3105 individuals in the United States, Canada and the United Kingdom was recruited by survey firms that administer internet surveys to nationally representative population samples. Measured familiarity was higher than expected, with 8% and 45% of the population correctly defining the terms geoengineering and climate engineering respectively. There was strong support for allowing the study of SRM. Support decreased and uncertainty rose as subjects were asked about their support for using SRM immediately, or to stop a climate emergency. Support for SRM is associated with optimism about scientific research, a valuing of SRM’s benefits and a stronger belief that SRM is natural, while opposition is associated with an attitude that nature should not be manipulated in this way. The potential risks of SRM are important drivers of public perception with the most salient being damage to the ozone layer and unknown risks. SRM is a new technology and public opinions are just forming; thus all reported results are sensitive to changes in framing, future information on risks and benefits, and changes to context.

Keywords: geoengineering, solar radiation management, climate change, public opinion, public awareness

3.4. Conspiracy theories
One of the voices emerging in the SRM debate is that of ‘chemtrails’ believers. This small group believes that organizations, such as governments, are already distributing chemicals in the atmosphere for a variety of purposes, ranging from culling the population to mind control. We found that 2.6% of the subjects believe that it is completely true that the government has a secret program that uses airplanes to put harmful chemicals into the air, and 14% of the sample believes that this is partly true. Distributions across the three countries do not vary substantially.

No mention of any further investigation into this aspect of the admitted SRM and GEOENGINEERING. So basically, the text admits to SRM & geoengineering, AND CHEMTRAILS. It only SPECIFICALLY addresses ‘culling the population to mind control’ in a manner that suggests those two to be ‘fringe’ opinions of ‘conspiracy theorists’… So what of OTHER applications, content mixtures, purposes? No mention…

Nanotech? SmartDust? Bio/pharma?
