I am avoiding having any views on fracking as it raised a few controversies here last time it was discussed. It seems rather drastic to me, but I believe that similar techniques have been used for some time.
It was a very interesting tour, also very tiring as there are four floors to the building and long corridors.Two hours walking about, plus a longish walk from the bus and a walk between buses too, as I missed the direct one I meant to catch. Luckily we stopped for a cup of tea and a biscuit at halftime.
The BGS are the largest section of the Natural Environment Research Council and they have a finger in everything - UK geology, carbon capture, climate change, earthquakes, energy, groundwater, landslides, mineralsUK, shale gas, technologies.
Their news and events page has a list of what is on (not just in Edinburgh) including a Family Fun Day at Keyworth. Sounds a good outing for an even slightly scientific grandchild.
