Video from earlier today: Russia's deadly wildfires, the smog-filled cities and poor harvest, are being seen by some environmentalists as signs of man-made climate change. But Piers Corbyn of the Weather Action Foundation says the heatwave is only down to climate cycles.

Piers Corbyn: "No, the only connection is that man is here the same time as the sun and the moon....climate change scientists are on the gravy train."
