Welcome to the York Skeptics homepage. We are a group dedicated to the promotion of science, rationalism and critical thinking in North Yorkshire. Every month we meet up for a friendly discussion and a talk from a speaker about a subject relating to science and critical thinking. Meetings take place every fourth Monday of the month at 7:30pm in The Phoenix Inn.

We now have a blog, which you can find at yorkskeptics.blogspot.co.uk.

What's the talk about?

Our July talk will be given by one of our own. Regular attendee John Cossham.

John has been studying all things green and sustainable for 30 years and has an Environmental Health degree, although he works as a juggler and balloon modeller. He has been a Green Party candidate in local elections and has a history of volunteering, including Frack Free York, York Rotters, Alternatives to Violence Project and many more. He has a special interest in atmospheric chemistry and anthropogenic climate change. He won the Oxfam Carbon Footprint competition in 2008 with the lowest in the UK.

John's talk on methane covers its biological and geological origins, and helps explain John's opposition to fracking. Methane is a powerful greenhouse gas, but short-lived, and these topics and their implications are explored in some detail. Finally, a newly identified environmental threat, methane clathrate, is exposed as having a possible role in our extinction, which could be sooner than expected.
