WHILE many readers may not approve of the recent direct action of climate change protestors, the motivation for their challenge is sincere.

Schoolchildren’s protests across the globe are prompted by the same hard evidence. Unless we substantially reduce our reliance on fossil fuels, our climate is doomed to irreversible change within our children’s lifetimes.

From the election leaflets that have recently been dropping through our letterboxes we should make a clear choice: between those candidates who are concerned by climate issues such as fracking, and those who would prefer us to remain docile and in the dark.
