Re: Utter Tosh
I call "Utter Tosh" for a completely different reason: The dear Speaker is simply talking out of his arse.
Irrelevant of anyones' stance on the whole weary AGW discussion and related subjects, the whole thing has generated an immense amount of actual scientific research into how our atmosphere actually works, if only to dis/prove certain (pet) theories. Besides often sparking more Discussion, all this work has had a profound effect on the one practical discipline in this area: meteorology. The day-to-day weather prediction is the one thing that affects us most, and accurate mid- to long-term prediction of weather is a serious tool in managing a lot of economic activity and planning. Meteorology has grown from something of a Dark Art to a full science over the past couple of decades, and it has hugely benefited from all the data points and measurements that are being made about our planets' atmosphere. It also has the added bonus that between prediction and actual result even a half-trained amateur can check how well the predictions are. And no, not in the "it's not raining here, mate" sense, but it's really easy to check if the predicted progression/development of a weather front actually matches reality, and how far off that prediction is/was. Weather is strongly affected by Quantum, but if the atmospheric models are correct, things generally should end up where they're predicted.
And they don't. Short term ( up to three days) they're OK-ish, but mid-term ( about a week) the predictions are still ... prone to change..., and characteristic elements ( fronts, pressure centers, temperature boundaries,....) end up in significantly different places than predicted. Which means the models simply are not good enough... yet... Which can and does have some serious implications, as the failure to correctly predict the landing place of Sandy shows, for instance.
This all amounts to a number of very simple conclusions: Our atmosphere is significantly more complicated than previously thought. We do not know enough about quite a number of phenomena/cycles and their interaction to correctly model them. As a result of this, any result the models give is at best an educated guess.
Conversely, if someone boldly claims this One Simple Solution will Save the Planet, you can be pretty sure he's talking out of his arse, if not selling Snake Oil. If you're buying that kind of stuff, I have got this great! opportunity! to make $$$! in your spare! time!!! And that's cutting me'own throat, mister!
