To one side I heard braying and I looked – two young men, City types in pinstripe suits were ridiculing my tatty cut-off jeans. “Oh well, at least they’re communicating” I thought, so grinning like a Cheshire Cat I wandered over to talk with them. “This is all bollocks” said the first. I listened respectfully and then asked them what climate facts they knew. They went on about all the investments they were pouring into electric cars. I told them it wasn’t enough, quoted the IPCC’s requirements to them, that emissions must halve in the next ten years. “Not going to happen” said one of them.
