Given the weather in the US in the last week or so, I though I would re-watch The Day After Tomorrow. Where do I begin?
The idea that there could be radical and very quick climate change is interesting. I don't think anyone would expect anything so fast for any reason (a few weeks going from now to ice age) but you almost give them licence to do that for the purpose of making a film. An ice age that creeps up on you over 50 years is boring as a story line.
But then you get the real killer - the breaking the laws of physics in a film set our universe. You simply cannot make air, as a gas, cold enough to instantly freeze you. It simple does not have the mass and density to do it. Yes, it is dangerous, but nothing like what is depicted - showing effects similar to liquid nitrogen which is massively more dense than air. On top of which, in the eye of the storm, there is not the wind chill effect to take that heat away from you, it is still air. The eye of the storm would have felt a darn sight warmer.
But looking deeper, the whole story line seems to have a political theme to promote the global warming agenda. The moral of the story is that we did this to ourselves with carbon emissions. Yet the very start of the story is based on a climate model of the last ice age starting 10,000 years ago. Now that was not caused by us pumping crap in to the atmosphere. So the whole story line is inconsistent at best.
Anyway, apart from all that, it is entertaining - as a basic quest and survival story line for a father getting to his son through impossible odds to keep a promise to rescue him
But it does make me wonder if I should post more on my views on climate change. I have to say that I find myself in a very odd position. Normally, in any argument that pits intuition against science, I have to take the science viewpoint. It is so easy for us to feel and guess differently to reality (and perceptions of risk is one of the areas we are so provably wrong so much of the time).
But I find I am siding with the skeptics a bit because science is being so mixed with politics.
But then, I think, take a step back and look at this. Lets assume for a second that the climatologists and scientists and politicians we hear about are 100% correct, that (a) we caused all this and that (b) we can fix it, at great cost to industry and economies. We'll get the Earth back as it was. Yay!
So we live on a planet that has major climatic swings as a matter of course. Humanity has lived through ice ages as well as tropical climates that leave us with fossils of sea creatures half way up mountains. The world has, and will change massively.
If we have made some small dent in that, good or bad, I am impressed. Basically, whatever we have done, or if the climatologists are right, what we may undo, will be a drop in the ocean in terms of what will happen in thousands of years, if not hundreds.
So we cannot actually change anything apart from the timing. Maybe we put off global warming a bit with all this work, yay! Maybe we bring the next ice age closer because of this work. Either way a generation of humans, at some point in the future, will face a massive upheaval of a society wrecking scale.
Why does it matter exactly which generation faces that?
If we did not spend all this effort on avoiding global warming, we would be better off. We could, perhaps, spend some effort on how we would handle climate change when it does happen.
At the end of the day we are not saving the planet here, it will be fine, we are trying to make life easier for a generation of people that may be our children or their children or their children. It is understandable, but we are missing the point! What we are doing is creating a legacy of annoying rules and regulations to combat climate change for us and our children and their children. It will impact generation after generation, creating hassle and cost, and then the climate change happens anyway, eventually.
