WHEN I first starting writing about climate change, Ann Winterton was MP. I got back the denial response (climate change isn’t happening), then the response that if climate change is happening then it isn’t manmade.

This misses the point; if there is a problem then the critical question is NOT who caused the problem, but who can solve the problem or, putting it more personally, what should I do?

The Danish theologian, Soren Kierkegaard, said that most of the world’s problems could be solved with three minutes thought; this is certainly true of climate change.

Broadly we know what we have to do. We have to eat less red meat, use less energy, insulate our homes, develop new green technologies, use cars less, walk and cycle more.

All that is needed is the will to do it.

After saying that most of the world’s problems could be solved with three minutes thought, Kierkegaard added, ‘but three minutes is a long time and thought is tiresome’.

Are we willing to change our diets and change our habits, or will we continue as we are and change our common home for the worse?
