I think it's pretty unlikely that your quick googling arrived at an angle that scientists haven't considered, to put it a bit bluntly.
There was merit in my original question … which was made long before any "googling" was undertaken … if you bother to read the last 10-15 posts of this thread you'll see that quite clearly I was asking a question.

At least I was contributing positively to this discourse. Whereas you, quite frankly, are just bringing people down. Surely someone as intelligent as you obviously are has something better to do.

What happens in the earths core is somewhat of a "black box" issue. We now some, but we are currently not able to link it with any of the normal renewal processes like Poisson that is used today because we do not have enough data/parameters. The rate of the magnetic reversal is statistically random, unless you operate with a "short" timewindow, and since it is random the rate that it changes is also different each time. Predicting these reversals or building accurate models is difficult beacuse we lack data (black box). The same as predicting earthquakes. We can detect some patterns, but we can not predict far into the future with any accuracy.
Cheers, great reply TY! ;)

Eh? What are you on about? I never said there wasn't any merit to your question, which is why I wasn't replying to your original question. I was just pointing out that there is no reason at all to suspect that the magnetic reversal isn't being taken into account by climate scientists. You're being awfully defensive.

:lol::lol: That's precisely what you did … you even chose to directly bait me with a phrase I used in my own post "to put it bluntly".

If you wanted to answer my original question then: "No" would have been one way to go! Perhaps even adding a reason why might have been nice or even polite. But to ridicule me for asking the question in the first place defeats the whole object of the thread and is quite frankly rude and pathetic … to put it bluntly :D

Thanks for the insight. Sounds an awful lot like chaotic dynamics except we don't know the complete dynamical equations to make a guess? Is that the case or have I misunderstood?

Sweeping generalisation there don't you think.
I am part of the 'older generation' as you put it and while non know when we are going to die, I am still passionate about the future of our planet.
Don't forget lots of older people have grand children to consider.

I am convinced that the human race has enough ingenuity to be able to contain the worst effects of global warming but someone needs to take the lead.

I have written to the CEO of a number of leading UK companies asking them to consider spending 50% of their advertising budgets on either acquiring large parts of rainforests to prevent deforestation or buying cheap land and planting new forests covering thousands of hectares.

This is a relatively cheap and zero risk start and those companies will get massive benefits from doing this.

We simply cannot all sit looking at each other and do nothing.
The higher technology things like CCS can then mature into viable methods.
I think it's a fair generalization considering the number of older people in countries such as america who vote for right wing parties that deny the existance of climate change.

The saintly Obama, beloved by plebs and bankers alike!
He's basically just a likeable version of Hilary Clinton and I say this as one of the biggest Obama fanboys out there who only got interested in american politics due to his 2008 campaign.

Why renewables can’t save the planet

Will people please understand. Our planet will be perfectly fine without the human race trashing it and behaving like we own it.
It is the human race and all life on our planet that need saving.

Without humans the planet will soon recover and another species will come to dominate.

I am impressed. Thank you for that.
You shouldn't be. Here's a place to do the calculation. It also does other things, e.g. flights.

EDIT: It's in the same ballpark as a two and a half hour flight, for comparison.
EDIT 2: Two hours and 15 minutes actually.

Much appreciated and thank you for your time. Makes you think about these things when we have this level of information.
Now. If he had walked the 944 miles I would definitely been impressed.

No worries, I think a lot about stuff like this anyway. To be honest I've considered not flying anymore unless my work demands it off me due to it being a good way of emitting a whole lot of CO2 in a short amount of time. It's proving to be difficult planning vacations with my girlfriend.

If he had walked it we wouldn't have heard about any of it, not yet anyway. It's still an impressive walk though. :)

Sanctity, like a cat, abhors filth.
I would walk 944 miles, and I would walk 944 miles more, just to be the man that walked 1888 miles...

For the betterment of the environment for all of our grandkids.

But also I can imagine after walking 1888 miles I may well fall down at your door. Assuming, of course, that your door was where my long walk reached its conclusion.

We have done a similar thing. Me and my wife really enjoy going on cruise holidays. However, it is very obvious how much pollution and CO2 these ships produce. In particular when they are in port all the electricity is generated from dirty diesel engines as we have stopped going.
I often feel like we are missing out on such fantastic holidays though.

It is the basis conundrum. We don't go but the ships are still sailing. In fact every year there are more and more of them to keep pace with demand.

That's the thing. Why would you limit your own experiences when everyone else don't care? People have to do it to an extend that sees fewer ships and planes take off.
I guess that sort of "boycott" has to start somewhere though.

Why renewables can’t save the planet

he raises some interesting points but it all seems pretty biased to me

no mention of how renewables are quickly becoming more and more efficient

and downplays the negatives of nuclear

There's a lot of disingenuous nonsense in there.

The UK government love nuclear power, and yet high-profile projects keep failing unless they get ridiculously high guaranteed prices. We also still don't have an agreed location for the geological storage facility that is needed for nuclear waste.

He also doesn't seem to understand that Uranium comes from mines, which are actually quite big and have their own environmental impacts, and is not an unlimited resource. I

He states that nuclear is difficult to vary to account for the changing output of renewables, but doesn't say what his solution for varying demand is (France deal with this by giving people dirt cheap electricity off-peak to try and even things out, and also by being interconnected to the rest of Europe). The intermittency of wind and solar can be managed by better energy storage - a technology area that's improving rapidly.

And Germany moved away from Nuclear toward Coal because they over-reacted to Fukushima, not to provide capacity for renewables.

Anyway, an energy mix is important, wind/solar/nuclear/hydro can all contribute. We need to mitigate the downsides of all of them. Putting all our hope on one technology (lol, fusion) is stupid.

If something is in a Ted X talk, I pretty much assume it's at the very least wildly misleading, and quite possibly completely wrong.

Why are all these far right Brexit twats ganging up on that climate change girl? Am I missing something here? What's the connection apart from the lack of any critical thinking and willingness to accept scientific evidence?

He's just a cnut. Probably woke up and asked himself 'whats the cuntiest thing i can do today'. Wishing death on a 15 year old just fit the cnuty bill. Aaron Banks isn't really a true believer with brexit anyway, he's in it to make money off the shitstorm that follows.

Because she is better at dividing us than uniting us?

I don't know, it's more of a theory but here goes: At first, Greta really hit home. Everybody's eyes were on her, ready and willing to listen. A child goes on school strike, unites us.

Then it changed, she didn't go back to school. She blamed, her views intolerant and then became a leftist figure publishing books and blaming prior generations.

Maybe people's views best change by pulling them in the right direction, not pushing them. Greta's angry "HOW DARE YOU!?" speech at the UN doesn't unite, it's a rather massive push.
