Sir - Michael Tyce (Letters, November 30) has developed a cynical and extraordinarily myopic view of people who are concerned about climate change and its impacts.

If he had a child who was 'likely' or 'very likely' to be affected by a fatal disease, he would wish to investigate every possible way of removing that threat. If he found that his waste was likely to cause fatal illnesses to his neighbours, I hope that even he would not await the definitive proof that his lifestyle was damaging others. Similarly, given what we are told by climate change scientists, we don't have to await certainty. Most of us can see the evidence of melting ice caps, repeated temperature records and the damage caused by cyclones in countries such as Bangladesh to convince us of the need for action.

It may be difficult to imagine removing nuclear power from the desired portfolio of energy solutions, but it's hardly surprising that many still find this a solution too far. Despite the protestations of the French, it is hard to see burying nuclear waste as a sustainable practice when it will remain radioactive for thousands of years. Perhaps more obvious these days are the concerns about encouraging the proliferation of a deeply dangerous technology: after all if nuclear is good enough for us, it should be acceptable for other states too.

Tyce's belief that those concerned by the environment somehow enjoy the pain of having to do without the benefits of technology we have all enjoyed over the last century is risible. Perhaps he should get out more and meet the growing number (including adherents of all political parties) who think that a concern for our environment is simply a concern for what sort of world we leave our children.
