Having been in the renewables business longer than nearly everyone, we know a bit about the climate-change issue. I am not strongly on either side of the argument, which most people interpret as meaning that I am strongly sceptic, and that interpretation is entirely wrong. I have spent most of my life and risked most of my family wealth in developing systems to replace the use of fossil fuels with renewable natural resources. Very few other people have gone that far, and virtually none has made a successful business out of it.
What I say is that when you see the effects of quite a small volcano on the environment and on business, you have to wonder whether the emissions from Man's rapid use of fossil fuels and of Calcium Carbonate, have anything like as much effect on us as the activity of the sun (whose reduction contributed to this cold winter in Europe and Eastern USA), or eruptions from volcanoes and other irresistible natural occurrences.
