You who fly from conference to conference, have two homes, one near the water, consume consume consume, and make your money from growth. You are going to tweet about global warming?

Worth reminding that individual virtue will make little dent in environmental pressures. Every litre of oil you don’t use, makes oil ever so slightly cheaper, so that someone else will buy it. The main effect of, say, deciding to take bloody inconvenient trains instead of flying, isn’t from the effect on emissions — the plane will fly without you, the effect is marginal — but signalling to others that you care and that it matters.

Signalling is an ugly word these days, but I guess it can be worthwhile. As long as we’re clear that individual virtue won’t cut it, and the focus is firmly on legislation, changing economic incentives, making polluters pay etc.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
