I've just "launched" (i.e. hastily hammered together and shoved online) a new blog, focusing more on my professional work. That'll be the place for info about my carbon footprinting, schools workshops, and climate change speaker stuff. I won't post on it very often - it's more of an info hub for plugging the various bits of paid work I do in order to pay the bills - but if anything interesting happens over there, I'll let you know. In the meantime, you can expect the sporadic, eccentric updates on this blog that you've grown to know and vaguely register.
The reason for setting up my pro blog now is that there's an exciting project I've been working on for a while that's about to go live...watch this space.
