Should we be worried about their effects on our health? What Are Chemtrails? Is Astrology Real? I had my hair tested," she says. And I live very healthily. Russ claims he found six times the safe levels of aluminium in his rainwater, and both say the tests are solid proof of atmospheric spraying.

It's not known what's behind those test results - and they couldn't be independently verified. Scientists, of course, disagree that there is any large-scale plot by governments to spread chemicals around the globe. A study by the Carnegie Institute for Science and the University of California Irvine surveyed 77 leading atmospheric scientists and geochemists.

All but one, The one scientist who dissented recorded unusually high levels of atmospheric barium in a remote area with low levels of barium in the soil. But to get from that one result to the idea that we're being secretly sprayed with chemicals requires a monumental leap of faith. But as for me - this is happening. Blog by Chris Bell.

Her beliefs don't exactly come from nowhere. Suzanne Maher says her group has bought more than 20 billboards across North America. The conspiracy theorists won't be swayed. We work on theoretical proposals for combating global warming called solar geoengineering or albedo modification. These are technologies that might enable people to add materials to the Earth's atmosphere to reflect a bit more sunlight back to space, partially masking or reducing the climate change due to accumulated greenhouse gases.

Study of solar geoengineering is in the very early stages and the topic is rightly a very controversial area of climate policy because if it ever were tested at large scales or implemented it could involve physical risks and would raise a range of serious socio-political and ethical issues.

However, there is nothing secret about the study of albedo modification, with hundreds of publications about the topic in academic journals and hundreds of articles in mainstream media. You can find some of our work here. We are confident that there is no currently active program to actually test or implement albedo modification outdoors.

We are not now involved in outdoor experimentation, though we are indeed actively developing proposals for field experiments. This experiment will proceed only if it is conducted in a fully transparent and public manner, and only if it passes a comprehensive independent safety review.

The experimental plans, operations and results will be publicly available and freely usable no patenting. Because of the apparent similarities between the proposed implementation methods for albedo modification such as injecting reflective particles into the stratosphere , and the alleged methods for producing chemtrails, some people have linked the notion of chemtrails to the study of albedo modification. Extraordinary claims require extraordinary proof. The claim that there is a large-scale secret program to spray materials from aircraft is extraordinary.

Yet all the evidence we have seen to date has been very weak. This as convincing as saying that alien beings walk among in disguise as people because some people act very strangely.
