Climate change progress up in air
Like so many of its predecessors, the Durban conference on climate change ended with observers wondering what if anything had been achieved, and a sharp difference between the optimists and the pessimists.
The South African chairwoman, Maite Nkoama-Mashabame, led the optimists. "We have made history," she declared. "We have agreed a plan to save the planet for our children and grandchildren."
Everybody would like to think that Durban has placed the planet on the road to salvation, but in the real world of rising seas and freakish weather the evidence was thin enough.
