One of the problems with discussing climate change is that a lot of people can't bear to hear the bad news. So unless you move in particularly enlightened circles, it's hard to raise the issue, let alone exchange ideas on how to tackle it. That is especially the case when environmental concern can be read, socially, as implicit criticism of anything from overseas holidays to the meat on the barbecue.
The good thing about a climate cafe is that it's a place to meet people who are also concerned, and who want to talk about what we can do - or not do - to help. So it might be an idea for Carbon Counts to set one up, say once a month, for whoever wants to drop by and see what ideas they can pick up. Those who want to keep on with the flights and barbecues presumably will stay away - at least until they personally face some major environmental event.
