London "Climate" Protests

Serious question for those who contend that human activity is leading to a catastrophic shift in the Earths climate.

If mankind had not spewed x billion tonnes of CO2 into the air, what would the climate be doing now?

Life needs Carbon .. in fact it needs a lot of Carbon.

I always wonder why these Environmental fanatics are not putting their energies into growing more forests .. or regreening deserts .. everyone would benefit.

Of course Planckton & seaweed would also benefit life.

But instead we get taxes .. given to the rich .. to create energy sources they own and charge the poor the most money .. whilst getting tax relief ! You cannot make this stuff up.

So why do they make such a big thing about it? I know there's a lot held in the tundra that they worry about being released.

I guess because its an excuse to say the word 'fart' on the telly. Anyway here's what Wikipedia has to say about -

Methane has a large effect but for a relatively brief period, having an estimated lifetime of 9.1 years in the atmosphere,[15] whereas carbon dioxide has a small effect for a long period, having an estimated lifetime of over 100 years.

TBH I find the Wikipedia entries on global warming just a little bit fishy. Methane, we know, will break down but no idea of the fate of CO2 is given although it is quoted as lasting over 100 years. It then talks of the reaction in the stratosphere while the pie chart shows that the vast majority of reactions occur lower down. Another page I found was basically sneering at scientists who disagreed with the great climate change theory.

Why? People spout out comments about population control, but have several kids themselves, fly across the world to have protests on climate change, its all meaningless hypocrisy
Do you mean why did I say it was insensitive and nasty?
Because what you wrote has got nothing to do with what I wrote
Your reference to Swiss clinics demonstrates a total lack of human sensitivity. If you don’t see that, then pity your family (not friends, I can’t imagine you have any.)

Whether you believe in man made climate change or not, the debate is helping drive the shift to sustainable energy production, and that has to be a good thing. I’m not sure people appreciate just how reliant we are on fossil fuels; not just as a cheap energy source, but also as a source of industrial chemicals that touch every aspect of modern life. The question that worries me more than anything, is can we wean our selves off oil and gas before their depletion leads to the collapse of civilisation. I do have faith in human ingenuity, and necessity is the mother of all invention, but if we are to artificially manufacture the chemicals we need, to replace what we currently just pump out of the ground in the form of crude oil, we will require massive amounts of energy.

Indeed, the waste of a natural resource by simply burning it cannot continue, however, simply running blindly down a cul de sac marked 'Batteries' without a glance to the left nor right is a most idiotic response and driven more by commercial interests than logical thinking.

NO! You are once more reverting to the stupidity of stating something then refusing point blank to back it up. As I said before, put up or shut up, or get yourself an education rather than parroting the idiocies of the EV industry.

Why should I have to point out the obvious. Just do your own research on the worlds largest battery. Just to give you a clue its not the one done by Tesla in Australia in fact it is 5 times larger than that and guess what its not a Lithium battery.

Personally, I remain sceptical about the practicality of batteries powering mainstream transport, but technology is advancing at a fair pace, so who knows. I don’t think we’re in a position to dismiss any particular technology at present.

Ive always been keen on hydrogen myself. I know it has its issues, but the chemistry of its combustion is so appealing.

Sigh... And that will fit under your bonnet will it? The whole point about sodium batteries is that the bigger they are the better, they also run at temperatures of 270C for maximum effect. As I have asked already, where are the smaller sodium batteries that are suitable for vehicles?

BTW, are there two of you behind this Renewablejohn name? You seem very forgetful of what you have posted and your train of thought quite disjointed, smacks of the left hand not knowing what the right is doing TBH.

The problem with going beyond the power density of what is available now is one of safety. It was some top physicist in the Canadian nuclear industry who pointed out that there may actually be a physical limit to how many loose electrons you can pack into a box without it blowing up.

Yes, I can well imagine the potential dangers given the propensity of automobiles to collide with one another. Mind you, petrol all over the road isn’t exactly a great scenario either.

Petrol is fairly easy to extinguish and cars are built with the tanks tucked well into a safety frame so the risk is minimised. A battery fire is a different proposition altogether as all you can do is try and cool them down while they react away, and they do get very hot indeed. Also worth noting that diesel is safer than either, but diesel is terrible terrible stuff nowdays, apparently.

And with the right tank design, I would think that gas fuel could be safer than anything, in a crash scenario.

Regarding diesel; I always wonder if environmentalists take into account the potential longevity of diesel powered vehicles, when they’re weighing up their environmental impact.

Yeah and ditch the mot, I like it!

Why keep on asking your quite capable of finding out for yourself. To give you a clue there working with Jaguar Land Rover . but there not the only ones just a British company at the cutting edge of battery development.

Who/whatever you are, it must be said, you are a complete ignoramus. You stated that sodium batteries are/will be suitable for EV's so therefore the onus is on you to prove it, that is the principle behind all debate from academia to the courts.

By playing these rather unoriginal mind games of yours, turning the principle on its head in pathetic bid to belittle your opponent, you are simply reinforcing the view that you are here to push some form of commercial agenda, may I ask whether you are being paid to do so?
