Environment: burning wood in power stations doesn’t help the climate
The living, not our forebears, have put most of the CO2 into the atmosphere. Substituting wood for coal in power stations doesn’t reduce CO2 emissions. A little warmth helps bell frogs fight chytrid fungus. Continue reading »

The gas industry has power and freedom to wreck the world
By now many citizens of our planet recognise that the destructiveness of climate change is moving faster than they imagined, leaving our defences at serious risk and even the money men are concerned about the burgeoning costs and possible economic collapse. Continue reading »
