Dedicated to the balanced discussion of global warming
Here is an excellent interview with famed scientist James Lovelock. Dr. Lovelock is best known for formulating the controversial Gaia hypothesis in the 1970s, which states that organisms interact with and regulate Earth’s surface and atmosphere. Later this year he will travel to space as Richard Branson’s guest aboard Virgin Galactic’s SpaceShipTwo.
If you read this site often, you know that I really don’t like carbon trading. I don’t think it will help solve any problems and it is only a way to tax people and push industries into doom. Dr. Lovelock appears to agree with me and he is a fairly strong supporter of the theory that global warming is man made.
Also in this interview, Dr. Lovelock discusses his favorite approach to reducing the overall carbon footprint. This approach of burying charcoal is not very popular and there are some other environmental concerns in the production of charcoal.

Your work on atmospheric chlorofluorocarbons led eventually to a global CFC ban that saved us from ozone-layer depletion. Do we have time to do a similar thing with carbon emissions to save ourselves from climate change?
Not a hope in hell. Most of the “green” stuff is verging on a gigantic scam. Carbon trading, with its huge government subsidies, is just what finance and industry wanted. It’s not going to do a damn thing about climate change, but it’ll make a lot of money for a lot of people and postpone the moment of reckoning. I am not against renewable energy, but to spoil all the decent countryside in the UK with wind farms is driving me mad. It’s absolutely unnecessary, and it takes 2500 square kilometres to produce a gigawatt – that’s an awful lot of countryside.
What about work to sequester carbon dioxide?
That is a waste of time. It’s a crazy idea – and dangerous. It would take so long and use so much energy that it will not be done.
So are we doomed?
There is one way we could save ourselves and that is through the massive burial of charcoal. It would mean farmers turning all their agricultural waste – which contains carbon that the plants have spent the summer sequestering – into non-biodegradable charcoal, and burying it in the soil. Then you can start shifting really hefty quantities of carbon out of the system and pull the CO2 down quite fast.
Would it make enough of a difference?
Yes. The biosphere pumps out 550 gigatonnes of carbon yearly; we put in only 30 gigatonnes. Ninety-nine per cent of the carbon that is fixed by plants is released back into the atmosphere within a year or so by consumers like bacteria, nematodes and worms. What we can do is cheat those consumers by getting farmers to burn their crop waste at very low oxygen levels to turn it into charcoal, which the farmer then ploughs into the field. A little CO2 is released but the bulk of it gets converted to carbon. You get a few per cent of biofuel as a by-product of the combustion process, which the farmer can sell. This scheme would need no subsidy: the farmer would make a profit. This is the one thing we can do that will make a difference, but I bet they won’t do it.
Do you think we will survive?
I’m an optimistic pessimist. I think it’s wrong to assume we’ll survive 2 °C of warming: there are already too many people on Earth. At 4 °C we could not survive with even one-tenth of our current population. The reason is we would not find enough food, unless we synthesised it. Because of this, the cull during this century is going to be huge, up to 90 per cent. The number of people remaining at the end of the century will probably be a billion or less. It has happened before: between the ice ages there were bottlenecks when there were only 2000 people left. It’s happening again.
I don’t think humans react fast enough or are clever enough to handle what’s coming up. Kyoto was 11 years ago. Virtually nothing’s been done except endless talk and meetings.
