Well, he did ask

Colin wondered (by text message).

My response to his wondering is as follows :

There are a number of things one could do to impact on the concentration of CO2 in the atmosphere.

One is to couple carbon capture and storage (CCS) technology with biomass. This enables you to remove CO2 from the air (using a plant) and capture CO2 (by burning the plant in a CCS ... er ... plant). This has been discussed. It requires you to be able to produce, in a sustainable manner, a lot of biomass.

Cquestrate have a rather novel method, which doesn't act on the atmosphere directly, but rather on the ocean. You can contribute to the development of this idea, since it is open source.

Cquestrate and AFS both require one to be able to generate a very large amount of energy in a way that does not emit large amounts of CO2.

What makes a man?

I am a rational being. I have 9 GCSEs, 3 A Levels (4 if you count 'General Studies'), 2 degrees and a wealth of experience, both theoretical and practical. I can tile a roof, cut a slate, align a laser, help to draft vague, non-committal statements on climate change[1], and patronise policy officials who don't understand the difference between kiloWatts and kiloWatt Hours.

So why, when I extract my headphones from my pocket, pannier or rucksack, and they are all twisted up, do I randomly pull, jerk and twist the cables, desperately trying to free the trapped ends? I noticed that, after about 2 minutes of doing this, if I patiently sat down and examined the problem at hand, it was trivial to calmly track the knot back to its source and undo it. A pigeon could have done it in 30 seconds.

Why am I irrational? Is everyone irrational?

[1] I didn't write para 23, but it's exactly the sort of thing I spent 2 years doing, and I doubtless commented on it at some point - and yes, it's meaningless

Some more photos of Fergus are available. He's the smallest one.
