Friends of Science (FoS) is a non-profit advocacy organization based in Calgary, Alberta, Canada. The organization rejects the established scientific conclusion that humans are largely responsible for the currently observed global warming. Rather, they propose that "the Sun is the main direct and indirect driver of climate change," not human activity. They argued against the Kyoto Protocol. The society was founded in 2002 and launched its website in October of that year. They are largely funded by the fossil fuel industry.
