After all the effort, the shuttle diplomacy, the scrambles for interviews, the maelstrom of thousands of people from nearly 200 countries jostling to be heard for a fortnight in Glasgow, what are we left with? Stronger words on a page? Yes. A commitment to a faster pace of negotiations? Yes. Delivery of promised aid for the poorest nations? Er, no. And a steep fall in carbon emissions as required by the science? Right, we’ll get back to you about that. So a mixed bag. One conference was never going to be revolutionary. And the outcome isn’t remotely dramatic enough. But did it send a signal about a sense of direction? Yes.
