Independent, 20 January 2016:
Richard Mountford keeps proposing geo-engineering as a solution to climate change, but conspicuously fails to identify any technology that might actually work (Letters Jan 14) Carbon negative technologies offer a much greater prospect of success.
For example it is perfectly feasible to grow sea-weed in prodigious quantities which would fix atmospheric CO2. This could be harvested and turned into biogas. If this was burnt in combination with carbon capture, then you would have an energy source that removes carbon from the atmosphere.
Obviously a large investment is required to turn such “third-way” technologies into reality. It is Britain’s tragedy that our scientifically illiterate Cabinet, in thrall to the fossil fuel industry, appears totally blind to the possibilities.
