The end of the world as we know it

[Poopadoop]

How do you think this will happen? I've ranked the three most likely (in my mind) scenarios.

1. Nuclear winter due to either an accident or some loony Dr. Evil type getting hold of nukes.

2. Planet goes on crazy exponentially growing feedforward heating loop due to global warming. Ice caps melt, every city on a coastline becomes another Atlantis.

3. Nature (asteroid, volcano, etc.).

[wufwugy]

1. Nature (asteroid, EMP). >>>>>>>>>>>>>>>>>>>

2. Everything else is minuscule in comparison. Nuclear winter is >0, but I think that has been avoided and will continue to be avoided. The global warming thing doesn't appear to stack up. It's the slowest of slow moving disasters (if it's a disaster in the first place) and probably the worst of it would result in all major coastlines using similar protections as the Netherlands does. I'd probably put biological warfare above nuclear, and probably technological (like Von Neumann bots) above nuclear as well. Granted, I don't think there is risk of runaway technological destruction like people like Musk are obsessed with.

[wufwugy]

I suspect that Earth will be habitable for biological organisms up until the sun expansion in 4B years or whenever.

I'm talking about humans, not some shit that lives in boiling sulphur water. Do you think we will still be here 4B years from now?

[OngBonga]

I'm talking about humans, not some shit that lives in boiling sulphur water. Do you think we will still be here 4B years from now?

No we won't be "here" in 4B years.

We'll be somewhere else, unless we've wiped ourselves out.

I'd say we've got 2B years to colonise another planet, which leaves a couple billion years for panic.

[wufwugy]

I'm talking about humans, not some shit that lives in boiling sulphur water. Do you think we will still be here 4B years from now?

That was just a side add-on.

[OngBonga]

This is a bit harsh on organisms so fucking hardy. Show some respect.

"Some awesome motherfucker that lives in boiling sulphur water."

[JKDS]

Super Virus/bacteria/etc, then Nuclear Winter.

While Global Warming is real and its consequences will be insane, I dont see us dying from it.

[Poopadoop]

Ya global warming could be survivable. I was just thinking of one that accelerates too quickly for us to deal with it. Though ya, probably unlikely now i think about it.

I think superbug is unlikely too though. There have been superbugs before and life went on.

[OngBonga]

I think superbug is unlikely too though. There have been superbugs before and life went on.

When we talk about the "end of the world as we know it", bugs definitely have the potential. The Great Plague would have been an EOWAWKI scenario, it radically changed the world. EOWAWKI doesn't mean end of human survival, it just means radical change in population and living conditions.

[Poopadoop]

Was the Great Plague EOWAWKI? I'm not saying it didn't shake things up but civilization didn't go back to the Stone Age or anything.

[OngBonga]

Was the Great Plague EOWAWKI? I'm not saying it didn't shake things up but civilization didn't go back to the Stone Age or anything.

Well it certainly radically changed the way people lived. Of course, we eventually emerged stronger as a species, but yeah I'd say the plague falls into the category of EOWAWKI... in fact I'd probably say it's a decent threshhold for what defines EOW... anything less significant is not probably not worth discussing in this context.

[a500lbgorilla]

Was the Great Plague EOWAWKI? I'm not saying it didn't shake things up but civilization didn't go back to the Stone Age or anything.

I think the world population went from 450 mil to 375 mil.

Something nasty that could break through our considerable defenses would definitely shake the world.

[a500lbgorilla]

Well, global warming will probably be very destabalizing for a lot of people. Not me though, I'm headed north into all that fertile Canadian post-artic land.

My money is on some natural disaster like an asteroid or volcano or Black Plague round 2.

[OngBonga]

Global warming is bollocks, jfc. They've been on about it for well over a decade now, our summers are still shit, and Pacific nations haven't been reclaimed by the ocean yet.

I'd say it'll be one of the following...

1. Economic collapse leading to WWIII... possibly nuclear, but even without nukes, the economic consequences of a war between USA & Europe vs Russia & China would be terrible for all parties.

2. Volcanic winter - Yellowstone Park being the prime candidate, but there's Katla in Iceland too which has huge potential, not to mention the chain of volcanoes around Indonesia.

3. Disease

4. Extraterrestial event - massive meteor. Most ET events would be devastating for the impact area only, it would take a monster like the one that supposedly wiped out the dinosaurs to fuck the world up.

[wufwugy]

1. Economic collapse leading to WWIII... possibly nuclear, but even without nukes, the economic consequences of a war between USA & Europe vs Russia & China would be terrible for all parties.

This may change to my #1, but in a different way. I think it will have more to do with rot of human institutions. The source of the rot is probably twofold: (1) people living sheltered lives and having no sense of the ways of the world. An example of this sort of thing can be seen in how many westerners embrace the proliferation of a movement whose goal is to subjugate, murder, and enslave those very westerners (Islamism). (2) The organizing principle behind Islamism and the state. They're both totalitarian and both have a featured history of near total eradication of culture and freedom.

I think there is a remarkably high chance that we're on a mostly unavoidable path of Equilibrium (the movie) level totalitarianism.

1. Not true. Westerners don't exactly 'embrace' Islam. Nor is the goal of any mainstream form of Islam to 'subjugate, murder, and enslave' anyone.

You could argue 2) is true in the sense of countries like present-day Iran and Saudi Arabia. But neither of these countries has shown any interest in exporting their own brand of theocracy.

Also a distinction should be made between fucked up governments and the religion they've hijacked to provide themselves with legitimacy. Historically, Islam has been a much more tolerant religion than Christianity, and much less inclined to subjugation. Two examples are the Arab conquest of Persia and the Ottoman conquests of N. Africa, the Mid East, and the Balkans. In both cases the conquered peoples were allowed to keep their religion, culture and language.

Western education has let us down.

It is verified that Islam has encroached and eradicated. It has been steady and effective. A less proximate cause for why Islam does this is because it is the way of Muhammad. Muhammad abrogated every other element of Islam, and he spread his message as a warlord. "Moderate Islam" is half in this world and half out of it. It is still mostly sharia, but with some small not-fully-Muhammad elements. Note that the Islamic reformation is ISIS. Even the tiny degree of secularization to some small areas of Islam across the globe is apostasy to the way of Muhammad. As all religious reformations do, they go back to the scriptures. ISIS is scriptural Islam.

Islam was created with the purpose of destroying Christianity and western culture. Perhaps a good way of going over the head of the propaganda education we've all received is to look at how and why Islam spread and what has become of those regions. It successfully destroyed the origin regions of Christianity (and western values) and turned them into >98% Islam. ISIS is trying to follow Muhammad by turning them into 100% sharia instead. Everywhere that Islam goes, it becomes wholly Islam.

There's much more but I'll stop here.

[Poopadoop]

Muhammad abrogated every other element of Islam, and he spread his message as a warlord.

The historical arguments go both ways. There's plenty of examples of Christianity being spread by force.

"Moderate Islam" is half in this world and half out of it. It is still mostly sharia, but with some small not-fully-Muhammad elements. Note that the Islamic reformation is ISIS. Even the tiny degree of secularization to some small areas of Islam across the globe is apostasy to the way of Muhammad. As all religious reformations do, they go back to the scriptures. ISIS is scriptural Islam.

I'll try to pick out the more coherent bits here and reply to them.

First, ISIS is radical, fundamental Islam. It is not mainstream but outside of that. Whatever you've been told or heard Donald Trump say is the propaganda. A lot of the people living as muslims in ISIS controlled territory fucking hate it and don't want anything to do with it. A parallel can be drawn with Iran. 90% of the people living there don't support the government and would prefer democracy. They ignore dress codes in private. They buy alcohol on the black market and drink it in their homes. They had public demonstrations over the election and the army opened fire. It's a fucked up place. ISIS is another case where a group of assholes have co-opted a religion for their own fucked up purposes of seizing power.

Islam was created with the purpose of destroying Christianity and western culture.

I'm not a theologian but I'd be surprised if that was it's purpose any more than Protestantism was created to destroy Catholocism, rather than as a reaction to dissatisfaction with mainstream religion and an alternative way of worshipping the same God.

Perhaps a good way of going over the head of the propaganda education we've all received...

You're implying that people with tolerant attitudes to religion have been unduly influenced by their education. I would argue you've been unduly influenced by xenophobic, intolerant individuals.

... is to look at how and why Islam spread and what has become of those regions. It successfully destroyed the origin regions of Christianity (and western values) and turned them into >98% Islam. ISIS is trying to follow Muhammad by turning them into 100% sharia instead. Everywhere that Islam goes, it becomes wholly Islam.

Events in the middle east >1000 years ago were pretty minor compared to how Christianity has been spread historically. I've also quoted more recent examples that directly contradict your last statement.

I'm not defending Islam, I think all religion is fucked. But I think your kind of thinking is dangerous because it promotes the sort of mentality that will lead to a modern day crusade.

It's very hard to believe that a media run by rich people are pushing an agenda that makes people want to implement policies which lose them money. You'd think the millions they spend trying to squash things like that would be somewhat at odds.

Well let's assume just for one minute that is is all bollocks. I wouldn't assume that their lies are losing them money, I would assume the opposite. I'm not going to pretend how the complexities of that works, but I'm gonna suggest that maybe it's for the greater benefit of big business due to excessive regulations killing the smaller competition. Fuck knows. But if they're lying about it, then they're not losing money, they're making it.

[OngBonga]

Because rilla needs it cleared up...

The difference between climate change denial and creationism is that one is based on paranoia (whether justified or not, that's the debate), while the other is based on religious delusion (ie there is no debate).

You're kind of missing the point of what science is. You don't assume what you were taught was right. You only have to look at the history of science to see that schools of thought are constantly questioned and changed when errors are found.

Also who is running all of this? Setting up a process of lies that no one can possibly see through what would have to be at least a century ago for what benefit exactly?

[OngBonga]

You're kind of missing the point of what science is.

Not at all. How can anyone put to test climate change in the form of experiment? Isn't that what sceince is? Theories holding up to experiment? That isn't what's going on here, thus, climate change is pseudoscience.

Fine, well for me climate change is on a par with religion. Those who buy it will defend its validity as though it is fact, when actually it is not fact.

Basically, people think it's fact because lots of scientists all nod their heads and say "yeah". That isn't what makes something a scientific fact. Theory holding up to experiment, that's what makes things fact.

At least recognise that there is a distinction.

Yep 100%.

In fact the increase in the number of ghosts from the increased number of deaths probably creates a chilling effect that would cancel any so called warming out.

[Poopadoop]

It kind of goes back to our previous discussion about nutrition. You can't do the experiment that proves conclusively that eating a healthy diet is good for you. So nutrition is a pseudoscience and you can just eat ice cream all day every day and you'll be fine.

Similarly, you can't do the experiment that proves global warming. But the indirect evidence is pretty damn suggestive imo. If you know that certain gases trap heat and you also know that those gases are being concentrated in the Earth's atmosphere, there's good reason to think that we're going to experience global warming.

[OngBonga]

What makes climate change different from ghosts? Lots of people think ghosts are real. Science can't prove they are not.

Neither can science prove they exist. Does that mean they don't? Fuck knows, but until it can be proven one way or the other, it's not real science. Even if every single scientist in the world said they believed in ghosts, without proof, it's not real science.

Climate change is no different, except more people believe in it.

We know that over the last 110 years, the sea level was rising. (That's as far back as the data goes)

We know that over the last 20 years, the sea level rose twice as fast. (Using, among other things, satellites).

We know this is caused by melting ice, decreased snowfall, and the thermal expansion of the water.

And we know all of that is caused by the increasing temperature of the planet. As earth gets hotter, the ocean gets hotter. (Interestingly enough, if we had no oceans we would experience a much wider range of temperatures. This is because water is hard to heat up in comparison to most other things.)

No reputable scientist disagrees. But, like with all things, you can bullshit any topic and get a following. Why might this occur with global warming? Because the solution involves cutting our heat emissions. That's expensive.

[OngBonga]

Here's a fact... when ice that is floating in water melts, the water level does not rise. Ice is less dense than water... which is of course why it floats. If you put ice into water, the level rises as a result of the ice displacing an amount of water equal to its mass. As the ice melts, it loses mass, and thus displaces less water. The resulting drop in water level balances out the gain in water level from the melted ice.

Melting sea ice would not raise sea levels. It can't, not unless the ice is not completely submerged. Thus, if ice is responsible for rising sea levels, it's meltwater from land, not sea. That would manifest itself in heavier river discharge from cold areas, which would be evident in the form of villages and towns on rivers downstream from meltwater regions becoming inundated, especially during spring.

Another factor that is overlooked... higher temperature means greater evaporation, both due to increased energy, and lower relative humidity. I would expect this to counter thermal expansion. Furthermore, water only starts to expand above 4 degrees, which means water that is cooler (ie, most of the water in the oceans) would actually contract as it warms, until it reached 4 degrees, at which point expansion begins.

It's all bollocks and you people just lap it up.

[Poopadoop]

Lol ong.

So those melting glaciers and polar ice caps aren't really melting?

It's not the water at the bottom of the oceans that's warming though is it? It's the surface water, and most of that is already > 4 degrees.

For sea ice, I assume you mean icebergs. I mean glaciers, which are not just floating icecubes. So yes, when glacier ice melts, it adds water to the ocean.

Fresh Water's density is greatest at 4 Celsius. Oceans are salt water. Salt water has different properties than fresh water.

[OngBonga]

This is a good point. But... when the numbers are adjusted, it could support my position further, rather than hurt it. I can't be bothered to research this right now, I might do tomorrow if mojo hasn't chimed in.

[OngBonga]

I've just torn to shreds the concept of thermal expansion of the oceans and all you have is lol?

[Poopadoop]

I've just torn to shreds the concept of thermal expansion of the oceans and all you have is lol?

It's lol because the evidence says the oceans are rising, it's measurable and indisputable, and your answer is 'no they aren't' and you add some arguments for why 2+2!=4.

[OngBonga]

It's lol because the evidence says the oceans are rising, it's measurable and indisputable, and your answer is 'no they aren't' and you add some arguments for why 2+2!=4.

How is it indisputable? Have you made these measurements yourself? Show me the indisputable proof.

They bounce a signal from a satellite, look it up.

[OngBonga]

They bounce a signal from a satellite, look it up.

"They"

Yeah, indisputable.

It's back to that issue of trust. Who are they? And how are they comparing such measurements with sea levels from a century ago?

[OngBonga]

It's not the water at the bottom of the oceans that's warming though is it? It's the surface water, and most of that is already > 4 degrees.

So we're talking about the thermal expansion of a very small percentage of the water in the oceans then? And we're saying that's responsible for sea level rise of measurable amounts?

And it doesn't matter if you're only heating the surface. That heating will, over time, work its way down. That's the nature of heat... it moves from a warm place to a cold place. If we're taking thermal expansion seriously, well it would be expected to initially expand the sea, and then cause them to shrink as the heat takes hold at lower depths. How long has this been going on? A century they say? yeah, by now the deep oceans will be warming up, if indeed the surface has been doing so for a century.

Yeah it's all bollocks.

So those melting glaciers and polar ice caps aren't really melting?

Which ones? There's definitely a lot of ice melting here in the northern hemisphere. More than average? That's the question. As far as I can tell from a quick google search, the Arctic melt this year is not breaking records.

[Poopadoop]

So we're talking about the thermal expansion of a very small percentage of the water in the oceans then? And we're saying that's responsible for sea level rise of measurable amounts? .

I don't know the ins and outs of how it works, but if the oceans are rising I assume it cause ice somewhere on land is melting and/or the water is getting warmer.

Again, don't know exactly. But if the surface heats up by 2 degrees and the really cold water is hundreds of metres down then I suspect it would take a long long time for that heat to work it's way down there. Heat's natural inclination is to rise, not sink.

You're mistaken here. I'll let mojo confirm it for you, but hot air only "rises" because warm air is less dense than cool air. Heat doesn't have a tendancy to rise, it has a tendancy to flow from a warmer place to a cooler place. Hot air has a tendacy to rise, this is not the heat that is causing this motion. It's increased average molecular velocity causing an "expansion" of gas, and therefore a decrease in density. Hot air basically floats on cold air.

[Poopadoop]

Hot water also floats on cold water. So I'm not mistaken. I do think most heat transfer in liquids comes through convection, not direct contact. Will need MMM to confirm though.

Anyways it's irrelevant if the fact is that the sea levels have risen arguing for why they can't have risen seems pointless.

[OngBonga]

Hot water also floats on cold water.

Yes it does, for the same reason. Warm water is less dense. Just because it's floating, does not means it's not losing heat to cooler water below. If warm water is in contact with cooler water, heat is flowing from the warm water to cooler water, guaranteed.

[OngBonga]

Anyways it's irrelevant if the fact is that the sea levels have risen....

But the evidence for this is flimsy. Prove me wrong.

You haven't tried to prove anything, you've engaged in discussion. I'm not proving anything, I'm making claims without backing any of them up, other than to say "mojo will clear it up", which in the case of heat transfer, he will.

I could prove it to you with links, just like you could prove to me that sea levels are rising, or at least attempt to prove it to me, by showing me the indisputable proof. But your proof is basically what you're being told by whatever media you're using to study this issue. You clearly have more faith than me.

But your proof is basically what you're being told by whatever media you're using to study this issue. You clearly have more faith than me.

Clearly. But if your starting point is to believe the opposite of what scientists agree on then I think I will end up being right more often than you.

I'm open to all possibilities and it's possible everything i've heard is wrong. But I can't really be bothered to spend time becoming expert in global warming, looking up papers and reading the fine print, then citing them to people i know on the internet who demand proof, and building a case like it's my life on the line. That's what I meant.
