Coal's in the news a bit recently. The G20 protests, some of which were about the lack of action to combat climate change, and the disgusting response from some of the police has put images of last year's Kingsnorth policing back on our screens. And then there is the pre-emptive policing of a proposed protest on Ratcliffe on Soar power station... another coal-burning electricity generator.
But this blog isn't about policing, however interesting that is. It's about Coal. Coal is fossilised plant remains from millions of years ago, and as such, is carbon which was sucked out of the atmosphere by those plants. When we mine coal, and burn it, that carbon is released right back into today's atmosphere. Whilst coal is underground, it is in an oxygen-free environment. When we dig it up, the methane (natural gas or 'firedamp') which is in the coal also gets into our atmosphere, and this gas is even more powerful than carbon dioxide for the global greenhouse. When the coal comes in contact with the air, reactions take place on the surfaces oxidising the carbon, so releasing carbon dioxide even before the coal is burnt, which of course releases ALL of the carbon it contains.
Supporters of he coal industry talk about 'carbon capture and storage', an experimental technology in it's early infancy. The theory might look good... take the carbon dioxide out of the gas leaving the chimney, pressurise it into liquid and pump this into empty gas fields, oil wells and aquifers... But large scale CCS is years if not decades away, and we really don't have that kind of time scale to continue trashing this planet. We have existing technology which would stem our carbon haemorrhage... insulation, switching things off, A-rated appliances, renewable generation... and I believe that some of the investment in CCS could (should) be spent on these proven technologies. I think that CCS does have it's part to play in a sustainable future, but I despair about disinvestment in renewables (for instance, what happened to Pelamis).
So, I want to invite you to participate in the Coal Caravan, a cycle trip from Nottingham to Blyth, starting on 24th April and finishing on 5th May, and taking in some of the biggest of the UK's coal mining communities. There's cycling during the day, and nature walks, visits to open cast coal mines, and then meetings with discussion or film showings in the evening. I hope to join them as they pass near to York, just for part of the day, to support the riders.
If some of you think that I'm being alarmist about climate change, then read what experts say in this website, 100 months. Some of the so-called' tipping points' seem to have already started... for instance there are disturbing reports of permafrost melting and raised methane levels in the arctic.... So, time is short. What are YOU doing to be a responsible ancestor?
