The arrogant, ignorant and utterly terrifying letter from UKIP's Richard Delingpole (Letters, 8.4.'15) is sufficient reason in itself for voters to give UKIP a very wide berth.

He clearly has no understanding of statistics or meteorology. At least his party's leader, Nigel Farage, is honest enough to confess that he "knows nothing" about climate change.

However, there is an overwhelming body of evidence and scientific opinion which demonstrates that man-made climate change is fact and is happening, and that this process's "tipping-point" at which, no matter what we do, our planet will, unstoppably, be on a trajectory to catastrophe, is very close indeed; probably not in the lifetimes of Mr. Delingpole or me, but certainly within a small few hundred years.

We are, in the overall cosmic scheme of things, microscopic beings existing on a tiny rock.

It is inconceivable that the stuff which we have been pumping into our thin atmosphere during the past 250 years since the Industrial Revolution cannot have had an effect.

Mr. Delingpole is, obviously, willing to put at risk the very existence of near-future generations, but I have faith and trust that the majority of people will take a different position: we simply have to.
