I have been looking through "There is no Planet B" to try to find Mike Berners-Lee's take on fossil fuels in particular. He is adamant that fossil fuels must be left in the ground, though he does not clarify how this will be done, apart from by "an enforceable global deal".

Virtue signalling - is it not about stating a position, but doing nothing, or the minimum, in that direction? Damian is doing more than many, if not more than most.

I do "enjoy" your thoughts Mossdog. Keep them coming.
