How ironic as Xi Jinping and 159 world leaders debate climate change in Paris: Beijing is having its worse day of pollution. The pollution readings have been off the scales as thick, heavy, putrid smelling smog descended on the city. Talking is good but it doesn’t seem to be making much difference in China. As here we need real and immediate action to solve the problem and stop it getting even worse. I just wish the conference had of been held in Beijing. Then everyone would know just how serious the problem is and see first hand what it does to the environment and city life.
