I was curious to discover what John Gummer had been doing since stepping down as a Conservative MP at the last general election to champion climate change. So I was only too happy to accept an invitation to hear him speak to Cambridge university students and city supporters last night, and join them afterwards for a fine fish supper at Loch Fynes.

Now Lord Deben, I found him a passionate, amusing and articulate speaker. He spoke about his work as president of GLOBE International – a global legislators organisation – and has more than a belly full of fire on this topic.  He was  more than ready to respond to sceptics, including Nigel Lawson:

“I have to say to the people who doubt this very simply that I know of no other occasion in human life in which I have to prove to you that it is unsafe, in every other circumstamnces you have to prove it is safe, and I think that it is pretty obvious that if you put a whole lot of alien gasses into the atmosphere it is likely to have some effect. We have an exact parallel because we did find that out with CFCS and the rest of them. What did we discover? We discovered that if you stopped using them, the hole in the  ozone layer became smaller. We used the science and we proved it.

“Isn’t it much more difficult to believe that it doesn’t have some effect? if you suddenly put – suddenly in terms of the history of the world – suddenly put huge quantities of gas into the atmosphere as you burn all over the world, would you not think that sensible people would say this might have an effect, and then you say to yourself there’s hardly an authentic climate scholar who would not say that the climate is changing and that human beings are responsible for it.

Nigel Lawson is wrong because even if he is right, we have to do it, but he is also wrong because it is illogical. It is illogical if a very large body of opinion suggests that this is a serious fact and we, because it is convenient for us, take the easy way out.  That’s always been wrong. In the end, say the sceptics were right, what harm has it done? We’ve created whole new industries, we have cleaned up our atmosphere, we have a healthier place to live and we have protected ourselves from over use of our resources. I don’t think there is an argument against it.”

He made it quite clear he was not ready to retire, he wasn’t interested in a laid back pipe and slippers lifestyle, and through GLOBAL, he has been assisting China to improve its environmental and climate change record so its people can see its blue sky once again.

“You are very lucky. I suppose if I am lucky I have got another 20 or 30 years, but many people here have got  another 70 years, but you have that in the most exciting moment that we have seen since Dante, and that must be worthwhile, and it should give us great confidence and great enthusiasm and a huge sense of responsibility.”

Lord Deben also talked about global population control re climate change (he does not believe it can be prescripted like China which he feels is disastrous as families are meant to have more than one child, and only children tend to be selfish), and that indigenous populations will be forced to flee into other regions if their homes are flooded in their search for a sustainable environment. He also talked about why Britian needs to be in the European Union to strengthen its future prosperity and trade agreements with other nations like India and America.

I really enjoyed listening to his passion on this topic, passions which I share. Aged 71 now, I am convinced Lord Deben will fight this corner to his last breath. Never mind Al Gore, if anyone needs convincing about climate change, then do not pass up an opportunity to listen to Lord Deben. He genuinely wants to leave the world a better place.
