"Well done sustain' for keeping up the 'air' pressure, for 50 issues, without getting tyred (sic). Of course there's only one issue really: humankind's deadly addiction to fossil. We squandered much of the time resource we had 10 years' ago, doubting, denying, dithering, debating.

" But that era has died. Now we are bravely facing our lethal addiction... staring it in the eye... The next 10 years will see unimaginably rapid and radical progress on carbon reduction. The big changes that are necessary, desirable and inevitable will simply happen... fast! Much more rapidly than we dared hope. And many will profit from doing the right thing. Burning fossil and creating carbon dioxide is at last recognised as crime against the children. Wherever it occurs, including our own backyard, we can eliminate it, like it were asbestos.

What an exciting 20-year period to be alive. Here's to the next 10, because that's exactly how long we've got: to all quit smoking fossil entirely! Not game over: this is GAME ON!"
