Guardian readers share their stories on the success of dowsing

Re your article “Water firms admit they still use ‘medieval’ dowsing rods” (22 November): in the 1950s, our family lived on a farm in an isolated part of northern Somerset. The farmer submitted an application for planning permission to build two new houses in a field, including details of water supply and drainage (there were no mains services at all). He had already walked over the field with his L-shaped birch twig, and we watched as the point of the L creaked downwards in his hands as he walked over a spot he had marked on the ground. A man from the water board arrived and looked at the site with geological maps. After half an hour he said “it’s anyone’s guess”, went back to his van and brought back his own birch twig. When he walked across the mark, the point of the L creaked upwards in his hands. He said that was the right place to dig a well, which the farmer and my father dug, and it never dried up.

I believe that when dowsers were tested many years ago, they were taken to a field under which was an underground reservoir. None of them located water. The farmer in Somerset told us that his own technique of dowsing only locates running water, so the reservoir would not have been indicated by this method.

EU votes to reauthorise the pesticide, ending a bitterly fought battle that saw 1.3 million people sign a petition calling for a ban

Glyphosate, the key ingredient in the world’s bestselling weedkiller, has won a new five-year lease in Europe, closing the most bitterly fought pesticide relicensing battle of recent times.

The herbicide’s license had been due to run out in less than three weeks, raising the prospect of Monsanto’s Roundup disappearing from store shelves and, potentially, a farmers’ revolt.

The United States Global Change Research Program report paints a bleak picture of the consequences of climate denial

The United States Global Change Research Program recently released a report on the science of climate change and its causes. The report is available for anyone to read; it was prepared by top scientists, and it gives an overview of the most up to date science.

If you want to understand climate change and a single document that summarizes what we know, this is your chance. This report is complete, readily understandable, and accessible. It discusses what we know, how we know it, how confident we are, and how likely certain events are to happen if we continue on our business-as-usual path.
