I’ve resisted the temptation to blog about Global Warming / Climate Change to date…
This is mostly because I try not to write about subjects in which I am wholly ignorant or unqualified to pass comment. I’ll start by saying I’m not a scientist (despite holding a BSc and being a hobby astronomer).
I’ve not got much to add to the debate, because I’m not a member of the IPCC an Oil Company or similar. I’m haven’t seen the data, and the likelihood is that I wouldn’t understand it. I don’t know enough about the properties of Carbon Dioxide, Methane and other green-house gases, nor do I understand the effects of the sun, moon, oceans, upper atmosphere or any of the other things that may or may not be influencing our climate.
I will make the following observations.
1. The debate seems often to be categorised into those who believe in man made global warming and those who don’t. This strikes me as very unscientific. You shouldn’t need to ‘believe’ in this sort of thing. Belief requires faith, and faith requires an unsupported leap of logic. Fine for religion, not for policy setting and remediative action. If you ‘believe’ in something here, I question your rationale.
2. Politicians are involved. Well, they’re involved in everything of course. Politicians exist to curry favour, make short term policy decisions and get re-elected. Nothing else matters to them. GW/CC is merely a tool to be used to further their aims from their perspective. Whether it be traffic congestion legislation, building regs or import and export tariffs. GW/CC is subject to massive manipulation for ulterior motives.
3. Lies, damn lies and statistics. Enough said.
4. Scientists need money. Scientists are no more independant than anyone else. You need money to live. Research requires money. Money comes from grants. Grants are awards by people or organisations with a vested interest. The right finding will get you another grant. This is not the fault of the scientists. This is life.
5. Computer models are used to predict dire consequences. I’m a computer expert. These models are utterly falicious. Even the best are simplistic, vague approximations of reality, which do not reflect reality in the slightest. The only way for a computer model to be taken seriously is for it to be benchmarked, by which I mean that it needs to accurately predict the future over a long period of time. Start a model now and lets see how ‘on the ball’ it is by 2019. If it’s accurate I’ll eat my hat. Has any model achieved anything like this to date. No. Don’t believe a computer model.
6. We do not know enough about what is going on. We don’t even know what 85% of the universe is made of (dark matter and dark energy are pretty much the same as ‘here be dragons’ on the edge of medieval maps). We live in orbit around a massive nuclear fusion bomb, drenched in radiation, affected by gravity with an ecosystem orders of magnitude more complex than we can comprehend. Our ignorance is staggering. Let’s not flatter ourselves that we can make policy decisions based on ‘fact’.
However.
And this is a big ‘however’.
We are wasting the Earth’s resources at a frightening rate, we are overpopulating the planet, we are chucking all sorts of pollutants into the atmosphere. Oil, gas and coal are a finite resource. We should act as long term custodians of this planet. We should clean up our act regard of whether GW/CC exists or not, or is caused by us or not. We’ve got one planet, and no access to any others.
Reduce, re-use, recycle. It’s a good idea anyway!
