The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious….

The World is full of wonders, but they become more Wonderful, not less Wonderful when Science looks at them..

How could I look my grandchildren in the eye and say I knew what was happening to the world and did nothing..

I'm no longer sceptical. I no longer have any doubt at all. I think climate change is the major challenge facing the world..
