Q: The government needs to address the cause instead of trying to look at consequential damage and ways to minimise it.

A:At this stage in the proceedings we do most definitely have to look at both causes and effects.

Even if we were to be able to magically stop all GHG emissions tomorrow, we would still have to address the changes that we have brought about by 200 years of fossil fuel use. In fact, it is utterly unrealistic to suppose that we can stop all emissions tomorrow. There is going to be a protracted run-down period when oil gas and coal will continue to be burnt. Of ourse we wish to see this happen asap, but even so, there will be effects, which we are already seeing in places like Tuvalu, where the effects of sea level rise are already apparent.

Gaia is a system, with many complex and interreacting causes and effects taking place. Accordingly, our response needs to be holistic, addressing causes and effects at the same time.

As well as GHG reductions, we need to look at carbon sinks, primarily forest replanting, but also research into ocean fertilisation, which needs to be accurately places, so that the blooms are taken under by existent (but already weakening) downward currents.

If we avoid big sea level rises by these means, so much the better, and the Barrage will continue to generate energy (it will stop generating when it changes into a sea dyke). If we do not, the Barrage will be of immense benefit in preventing flooding. Remember that inundation will cause the inhabitants of five towns and many settlements to become environmental refugees, building new (shanty?) towns in Gloucester and Somerset. We will also lose much fertile land at a time when we will have difficulty feeding the population to our island since we are well past the carrying capacity.

Yes, it is a tough decision, but we live in extreme times.
