Re: Sunspot Minimum or "Is the sun going to sleep?"
 

When I was 6 years old my father took me to Fels Planetarium in the Franklin Institute and I watched a film about the sun. I remember hearing how the sun was going to burn out in 6 billion years and I spent the rest of the day in abject horror.

Sort of unrelated, but I wanted to share.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

There was a Science channel special on some abstracticians who were postulating how advanced intelligent lifeforms might survive in space once all of the stars burned out in billions of years. It was a very dismal existence indeed. They didn't even think about the lack of light that would be like driving down a dark road with no headlights on as the civilisations traveled from place to place. ::shudder::

I think we're on a role with Energy Conservation in general, and it'd be a shame if everything got cooler for a couple of decades. If you combine some NASA photos with findings (such as evidence that ice used to be at the top of a 1000-ft plateau in Madagascar) that support the 'Snowball Earth' theory, it seems logical that climate change is happening and that it can have huge ramifications. Yet I fear the uneducated masses will use a colder year that results from a docile sunspot maximum season as evidence that climate change is a myth.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Jesse,
We just don' have enough data yet. The Maunder Minimum, the longest period of no sunspot activity also coincided with the cold spell that gave Valley Forge such significance as well as all those winter scenes from northern Europe.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

It may be (who knows) that the sunspots, huge volcanic eruptions, etc. that produce extra-cold winters and summers are acting as counters to global warming, giving the earth a chance to recover.

It also gives those who are so inclined a chance to poke fun at certain politicians/scientists. After a May blizzard a couple years ago in SD canceled classes (seen on a white board in the student lounge): "What happened to the global warming?" or something to that effect, along with this response: "It's now called global climate change."

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

All I know is that High-Frequency (1.6-30 MHz) radio propagation is not all that good, and I'm anxious for more sunspots so I can "work the world on a Watt" again. This time on PSK31, I suppose.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I know this might be a tad off topic, but as some comments have been made in reference to global warming I have a quick question: why are people so convinced that human activity is dominant cause of global warming. I'm not saying it isn't (I'm hardly anything remotely resembling an expert on the area), but warming and cooling far beyond what we are experiencing has happened in the past (way before humans industrialized). Take the end of the ice age, when the glaciers covering a massive portion of the northern hemisphere receded. There were no people spreading greenhouse gases at that point, so it's not as if natural warming has never occurred. I don't doubt that human activity plays a role in global warming (or cooling), but I think people might be a little quick to exaggerate it.
Just my $0.02

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I just so happen to be one of those that likes a good jab at the folks that say global warming is happening. (And the best way to cool the earth? Have said folks be quiet and stop talking, because talking produces hot air!)

And I seem to recall that certain animals produce lots of greenhouse gasses (whatever those are:rolleyes:). As in, close to as much as humans do. (And there are some other things, but that would start getting way way way off-topic, so I'll leave it at that.)

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Multiple peer reviewed scientific studies support the hypothesis that humans are accelerating global warming. The consensus in the scientific community is that humans accelerate global warming. I could link to all of the papers if you feel like analyzing them (as you shouldn't just take people's word on anything in science), but I'm sleepy right now.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I'm not convinced that we're the dominant cause of global warming or climate change overall. I do believe that the profound impact we have on the environment creates a domino effect with sometimes unimaginable consequences. What we do cause, almost incontrovertibly I postulate, is rapid acceleration and amplification of localized events that slowly accelerate global change over what it would have been had we not made our impacts in the way we did. I believe it's been happening for centuries, yet it was nearly undetectable in the 1800's due to lack of global communications and the non-linear development characteristic of anything the human species does.

As an example, I'm pretty sure the French didn't analyze environmental impact in Haiti when they cut down 95% of the forests for, essentially, cash crops a long long time ago. Now, not only is the Haitian soil not quite suitable for food crops it also creates a localized effect of erosion and dust bowls. While seemingly minute, those logically contribute to the region's weather patterns (localized heating, high winds) which also effect the Gulf of Mexico.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I just read the same stuff as everybody else.

Warming is predominantly caused by water vapor, not SUV's and backyard BBQ's. The planet has this irritating habit of warming and cooling over time, for reasons mostly unknown. You may have heard of the ice age, it's real and thank the lucky stars we aren't in one now. We are just about on schedule to begin the next ice age. Just imagine, the NHL will expand like crazy. CO2 levels track the warming some time later, and are not the cause, at least, that's the historical record and it might not be true today. Impossible to know. All of the proposed remedies to global warming will have almost no affect on the average temperature, fractions of a degree over many decades at best. Some are using scare tactics to extract money out of your wallet, but that applies across a range of topics (warming, health care, banks, mortgages, car companies, education, terrorism, ...) and isn't new. Fusion power, if ever practical, will solve a lot of problems and ensure a bright future. As long as we get there before all the oil runs out in a few thousand years, we're good.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I know I didn't start a good precedent with this, but if we're going to argue about global warming and claim facts such as "what causes it", can we do our best to link to preferably peer reviewed s ientic journal articles on the subjects? Otherwise the debate will just turn into "I think this!" "No, but it's actually this!" "You're wrong! I know this for sure!"

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Peer-reviewed scientific studies are done by people. Also note the law of spontaneous generation.

(If you don't know what that law is, it was debunked by Pasteur a couple hundred years ago or so.)

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I'm not a climate scientist. I haven't spent a lifetime drilling ice cores out of Antarctica, monitoring thousands of weather stations, designing complex mathematical climate forecasting algorithms, mapping the hole in the Ozone layer, recording the cyclical ocean temperatures of El Niño, measuring the accelerated extent of the shrinking glaciers and rising sea water, or any other of the highly specialized tasks that these scientists do every day.

As such, what qualifies me as being more competent than they are at drawing conclusions from their climate data? Subjective arguments and logical fallacies? I'm not a climate scientist, or even a meteorologist. But they are. And the vast majority of them (including the IPCC) all agree that global warming is not only real and observable, but that activity from humans has been primarily responsible for this current rapid upswing. (Note they are not stating that humans are solely responsible, since climate shifts obviously occurred in the four billion years prior to humanity.)

If Global Warming, which is the currently held scientific theory among the majority of scientists worldwide, works well enough for those which devote their entire lives to studying the climate, then it's good enough for me. Letting politics or personal ideas get in the way of science is like when Indiana tried to pass a law rounding pi to 3.2 to allow one to "square a circle", even though it had already been proven impossible with primitive actions.

But at the same time, if enough scientists find sufficient telling evidence to refute or alter the currently held theory of global warming (which at the current time is pretty unlikely, but not impossible), and if the majority of scientists worldwide support these changes, then I'll support those alterations.

Now as for the sunspots, there have been long lulls before, and subjectively they seem to line up with generic climate trends. But the only way to be sure is with data, numbers, with which we can run statistical analysis with decimal-point precision on it, and with a certain degree of confidence, make conclusions mathematically about whether sunspots have anything to do with our climate, or if it's just another textbook case of "correlation does not imply causation".

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

That's funny.
I think your estimates of the amount of hydrocarbons on the planet is off by an order of magnitude.

Oil will never run out, but it will eventually become too expensive to use it as we do today. I expect that to happen in your lifetime.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Three points:

1.) I don't understand what is wrong with drawing your own conclusions from the data. The scientists studying global warming don't know everything about it (or why would they still need to be researching it) so what makes you so sure that your conclusions would be incorrect?

2.) Just because their is a consensus among the scientific community doesn't necessarily mean that that consensus is correct. Bear in mind that it was once generally accepted that the world was flat and orbited by the sun.

3.) I would love to read some papers on climate change. If anyone would be willing to post some links it would be much appreciated.

2 more cents from me.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Or, as I pointed out earlier, spontaneous generation, once accepted as pretty much law and now you can hardly find a supporter. http://en.wikipedia.org/wiki/Spontaneous_generation

To put it bluntly: Scientific knowledge can be wrong, even when the majority of scientists accept the same thing.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Insufficient data. I could put my opinion in a million ways, but that pretty well sums it up.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

When I was your age all the "experts" said we were in a period of global cooling and were also predicting that we were heading into the next ice age.

My biggest question is why don't the global warming experts allow scientist with opposing viewpoints make presentations at the global warming conferences, what are they afraid of?

Global warming, or now what they call climate change because the earth has stopped warming in the 21st century, has become too much of a religion and not a science. Until experts like the Prince of Wails stops predicting that the earth will be ruined in ten years or the Chief High Priests of the Church like Al Gore stop calling non-believers Nazis I won't take them seriously.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Because you're not a scientist and thus aren't qualified to interpret the data? Well, a climatologist. If you are, sorry for stepping on your toes though. (Yes, it's happened ._.)

Were these people scientists using the Scientific Method to verify their ideas?

I'll grab some tonight.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Let's take this argument for one second, and keep applying it recursively throughout history. If every generation used this argument to call into question modern advances in science because the previous generation held a different scientific conclusion, we'd still thinking the Earth was the center of the Universe, there were only five chemical elements, and if you throw lead in a pot and chant loud enough, it'll turn into gold.

This same argument, applied to a criminal investigation might look like this: There was a murder in Someville, and the murderer is still at large. In the years following the crime, there is little compelling evidence and they meet many dead ends. The case is officially declared cold. Thirty years later, DNA testing becomes widespread, and the case is reopened. Also, a witness to the crime comes forward no longer fearing retribution from a now aged murderer. The existing evidence is tested for DNA, and a match is found for a known criminal that matches testimony from the witness. Is it perfect evidence? No. But is it better than what they had thirty years ago? Yes. Will it be enough to go beyond reasonable doubt? That's for the jury to decide. But using your argument, this would say "Bah humbug about DNA evidence pointing to John Doe as primary suspect. The 'expert' investigators in my day said this case would never be solved!"

The only way this argument would hold merit is if technology did not advance. If the technology available now was identical to that 30 years ago, then it would be hard to draw new conclusions from data, and anything new could more easily be construed as running on nothing but hot air. But because technology advances, especially in the computing department, we can now process data trillions of times faster than 30 years ago. The enormous amount of computer data processing alone can analyze data much more thoroughly than can be done by hand, and ascertain subtle causation and correlation patterns in existing data. This data can then be used to create more accurate simulations which better reflect reality.

Engineering is a prime example of this. 100 years ago they had no such thing as CAD, computer simulations, or even a sort of mechanical calculators. Back then math was done by hand, and if they wanted a really precise answer, then that took loads of math. The more accurate they wanted, the more math. So they approximated a lot more back then. The Brooklyn Bridge was over-engineered by many orders of magnitude because the designers of the late 1800s did not possess a means of efficiently processing the vast amounts of equations necessary to build it just right. So they wasted a lot of money in extra materials as they erred on the safe side. Nowadays we have the computing power to do full bridge simulations on a computer, and engineers use that data to design a bridge that meets the safety requirements without being over-engineered. This saves time, money, and resources.

Unless opposing viewpoints have opposing evidence and facts to back them up, they are rightfully being kept out of science conferences. If opposing viewpoints have compelling evidence, then most scientists - as highly rational people - will accept this new held evidence into the mainstream. Over the last few centuries of modern science, there have been many "Earth-shattering" revelations in science (such as black holes, DNA, and optical Doppler Effect to name a few) that were ridiculed at first, but with enough evidence and repeatable results, gained their rightful place.

There have also been just as many scientists ridiculed and kept out of science conferences for perfectly legitimate reasons. The number of people who've claimed to invent "huge breakthroughs" and create "infinite free energy" aren't being kept quiet because of a huge conspiracy. They're being kept quiet because there is no data to support them, and therefore no scientific merit for their ideas.

Actually, even though most current scientists stand behind global warming, the Earth will actually be quite fine regardless of Global Warming. The Earth has survived over four billion years already, surviving everything nature has thrown at it, and is on track to survive at least another five billion years.

The problem with global warming is not the Earth, but life. And not just human life, but everything down the food chain from us. We need food to live, and we don't have the technology to feed the entire planet from food grown in petri dishes.

Now there are smug people on the left fringe who think by driving a Prius they are saving the world and anyone who isn't doing as they are is as you phrased it, "a Nazi". But the keyword there is fringe. The majority of civilized people won't call those which don't agree with them Nazi. For as many people as there are on the fringe giving a bad rep to a political idea (on either the left or the right), there are most likely 10 or more normal, reasonable people who agree with the idea, but won't give it a bad rep by acting like the fringe.

And besides, science in its true form cannot be a religion. Science doesn't ask you to believe anything blindly, purely out of faith. Science provides you with a determinate way to gather data, run experiments, and draw conclusions. And unless something has the data to back it up, it cannot be a part of mainstream science. While scientists 'believe' things, they mostly believe in the fact that their conclusions are the best possible result at the given time from the available data.

If I'm sick and go to the doctor, and they tell me I have XYZ illness, I don't look at them and tell them I think they're wrong because I read on the Internet that coughing and nausea are symptoms of ABC illness, not XYZ illness.

If I sign a contract with someone and they breach it, and I want a lawsuit to get what I'm legally entitled to, I don't tell the lawyer they are doing their job wrong because Judge Judy does it a different way.

Yes, there is nothing wrong with people drawing their opinions from data. But there is a serious problem with spreading a belief that your amateur "conclusion" has as much weight as the conclusions of those which devote their lifetimes to it. No, you can have an opinion, but unless you actually go to graduate school, or law school, or med school and leave with a diploma, you are not qualified to form an equal conclusion to what they are.

If this was the case, why even bother going to college to become an engineer if Joe Sixpack can form a conclusion equal to a senior engineer on critical details of a nuclear reactor? Or why go to med school if Jane Doe is just as qualified to treat medical conditions as a practicing doctor because she reads WedMD? Or why go to grad school for meteorology if John Smith can form a conclusion equal to a scientist based solely upon reading Drudge Report?

We have institutions of higher learning for a reason! Like it or not, people with genuine diplomas (honorary ones don't count!) from these colleges and universities are more qualified than Joe Sixpack in their specific field. Period.

Actually, most ancient cultures with any kind of advanced learning independently discovered the world was round. The Egyptians, Romans, etc all hypothesized that the Earth was round, because of several pieces of evidence, such as how ships would disappear over the horizon, or that at noon on a particular day in Egypt the sun would hit the bottom of one well but only get halfway down in another well 80 miles away. Actually, because of the latter, the Egyptians were actually able to calculate the diameter of the Earth to a startlingly accurate number thousands of years ago based solely upon these observed phenomenon.

By the time Christopher Columbus wanted to sail to India in 1490s, the educated people didn't honestly think he would sail off the edge. They knew the world was round, but rather their sticking point was that they believed Columbus was seriously underestimating the length of the journey east to India, hence their reluctance to fund him. When he returned home and claimed to have reached India but only traveled half the expected distance, they called shenanigans, and postulated that he hadn't reached India but rather found an entirely new continent - the Americas.

Now your part about the sun orbiting the earth was widely held belief for quite a long time. Copernicus and Galileo were not only ridiculed, but literally put on house arrest by the Church at the time they released their findings supporting heliocentricism because they contradicted with the then currently held geocentric ideas of the Catholic Church. (This was despite the fact that Galileo was a devout Catholic, and has actually been very good friends with the then Pope before he was the Pope, and they both had agreed that science and religion were not clashing but working together to solve different facets of the same problem. I guess a lot changes when you're in power.)

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Here is a little helpful hint for anyone who engages in a debate. Make sure that you don't just recall something you have read but that you know for a fact. I know what animals you are referring to. They are cows and they don't exist in the wild. Humanity is still responsible. Little jab meet right cross.
Again???? Your citing the Prince of Wales. The Prince of Wales is a moron. He thinks that a homeopathy is a good ideas. It defies the laws of physics.
Actually didn't that also have to do with the variability of manufacturing processes? It also interestingly enough was a good move by the bridge makers as they did discover that some of the steel was bad.
Then it wouldn't be science. Scientists at one point knew there was a problem with Newton's laws of gravity and Maxwell's equations. They didn't just think that there was a problem with those laws they knew there was a problem. They both worked and neither law could be fudged to solve the problem until Einstein.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I don't think I will convince anyone of anything, but I want to point out a few things.

One, in both politics and science, follow the money. In politics, there are people to gain by trying to get the public to agree about global warming, on both sides, but much more so on the "there is global warming side" at the moment. Recent examples of politics being played here and here.

In science, it is similar. Just remember, if human caused global warming were to be proven false, lots of scientists lose their funding and their credibility. That is also true about many governmental organizations, like the IPPC.
Are there people (yes, even scientists in the field) who disagree with global warming being human caused? Yes, for instance see here (letter) and here (signatures).


Have you heard about the object that recently hit Jupiter? Guess who discovered it? An amateur.

Take for example the main reason we post on this site, robotics. I know people who are not trained in any engineering who can design some extremely impressive robots.

I have worked with technicians who understand what is going on in a process much better than an engineer does.

In a company I worked for, after getting a bachelors and going into a research position for five years you were better off than the person who went to get their PhD in those five years. 1) You had experience the company valued. 2) Your five years were on-the-job like training. 3) You netted a whole lot more money than the student did.

How about Henry Ford? What education did he have?

Do you know why an "amateur" can sometimes be better than a "professional"? Because <i>if </i> they have worked with it, studied it, and come to an understanding of it from their own experiences outside of school, they can do just as well as others.

What is that to say? There are definitely some "amateurs" out there who have opinions that should be valued. In addition, if you are reading about a subject over a period of time, you can rightfully draw conclusions when considering the debate. Are you going to be able to write a paper on it in a published journal, unlikely, though there are exceptions, particularly if there is a great insight or discovery.

Just remember, "garbage in, garbage out." If I do not give all the data or I give a wrong set of equations or I don't give the right units, I can get something that looks great on paper, but will fail miserably. In the case of human caused global warming, I think an emphasis has been put on the last 25 years, particularly to the public. As IndySam noted, in the 60s and 70s, it was global cooling that was the "problem."

One thing that frustrates me is that sometimes the evidence is not brought to the table when it doesn't fit with a "scientific theory." For instance, how widely reported is it that since 2001, the average global temperature has remained steady, not an exponential growth.

Is the earth gradually warming? Yes, but it has for the last 150-200 years since the Little Ice Age. Yes, 200 years at the rate of about a degree F every century. The real question is: is it human caused? If it is, then all of the equations to predict global warming by IPPC are off since none of their predictions line up with reality (oh, you didn't know that? :rolleyes:). This is one of the things that bothers me when science, money, and politics collide (and not just in regards to global warming, but other issues as well that are not on topic). The scientific method goes out the window. One piece of evidence should be enough to cause a significant reworking of the theory at the least, but when money and politics is involved, it becomes more of a tangled web.

See here, here, and here (two pdfs links are linked from first link) for evidence.

Let's see, current "proven" reserves of crude oil are around 50 years worth. That doesn't include shale oil (estimated 2x proven reserves), oil that is not economically/technically feasible at the moment, and crude oil that is unproven. Suffice to say, I think we have enough for a while. Your statement about it becoming too expensive might be true, but I think that will be more because a cheaper (that oil today even) technology comes along.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Be very careful here Art. There are many people who devote their lifetime to a specific narrow-minded piece of work who then fail to see the larger picture. In pop-culture they usually become stuck in the 'doomsday sayer' group and simply wait out the rest of their lifetimes to say 'I told you so'.

You don't need a degree to be able to analyze data. If I were to judge it, I'd say that most people who can finish a Sudoku puzzle have enough logic and reasoning to analyze this data. Combine that with the plethora of news, evidence, and life experiences that sway the argument either way and even Joe Sixpack can make a logical, valid argument from his perspective.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Those are all exceptions, not the rule.

There will always a few exceptional amateurs that are competent enough in professional fields to do acceptable (or even amazing work, like Dean Kamen or your example of Henry Ford), but the vast majority of amateur people wouldn't even pass basic proficiency standards in specialized professional fields. That's why the average annual incomes of people with Bachelor degrees is higher than those without, and those with Master degrees is higher yet, with PhDs topping the charts. There will always be outliers, but this in general is the rule.

But in the 50s - 70s, the data at the time was showing that the Earth's temperature had stabilized. The decision at the time made sense that the Earth may have been entering a cooling phase. But since the late 1800s however, the temperature has generally "skyrocketed" in terms of the rate of the temperature increase in reference to the nominal fluctuations during the past two thousand years. 84% of scientists [source] agree with the findings that this recent upsurge since the "Little Ice Age" has been propelled to increase faster and to higher levels because of human activity than it would have otherwise occurred naturally.







If there was ever an educational course that singlehandedly changed my life, I would give the honors to statistics. Without statistics, localized variations like that might look like a trend. But sometimes we get "weird" results that point more to the randomness of noise in data than actual trends. An example of this can be said about rolling a pair of dice three times and getting doubles each time (sending you directly to Jail without passing Go in Monopoly!). The odds of this happening are small (1/216), but does it mean the dice are loaded or inaccurate? No, it just means your sample size is too small to be conclusive.

Localized trends (over a few years) can be affected by a number of localized environmental factors. Some factors we know about - such as the case of the Mount Tambora volcano eruption in 1815 causing the Year Without a Summer in 1816 - but others we don't. In general, predicting short term weather and climate variations is much harder than predicting long term ones since more variables come into play in the short term. In the long term, the short term variations are smoothed out (very similar to the Law of Large Numbers), making longer term predictions a lot easier.

As you pointed out, there is a lot of oil left. But we use petroleum for more than just making our cars go and supplying power plants. Fertilizer, plastics, lubricants, and many more various hydrocarbon-based products all depend on various byproducts of the oil distillation process. When the price of oil goes up, all those prices go up as well, resulting in very volatile pricing. And real economic growth does not like volatile pricing - that's why you see so many companies with price guarantees to sell anything for their competitors price if it's cheaper. This isn't to save you money, it's because stable pricing leads to higher profit margins for them.

Switching from oil to more stable sources of sustainable or renewable energy (non-corn* ethanol, biodiesel, nuclear, wind, solar, hydro, geothermal, etc) results in steadier prices (e.g. wind is always free!), which results in more stable economic growth and higher profit margins for industry. Thus, weening ourselves off oil is a smart and sensible long-term goal both economically and environmentally. The problem is the short term - volatile pricing can lead to massive short term profits for shareholders and executives then lead to a period of minimal profits at best or massive red ink at worst, as the financial industry is in now. These people are more interested in sticking around for five years, getting rich, and leaving the company rather than sitting in for 20, 30, even 40 years at the company and guiding it down the path of long term, stable, moderately-high profits.

* Corn is actually a pretty poor source of ethanol. Plants like plain prairie grass yield much higher returns, while not driving up the food and livestock feed prices for everyone else.

I'm not disagreeing with you. There are a lot of people who become close-minded to the big picture, both people with and without college educations. I've seen college professors with PhDs try to read deeper into things which don't really exist. Sometimes a joke or saying is just a joke or a saying. Others fall victim to confirmation bias after becoming attached to something, and fail to have the ability to see why or how an opposing group holds their particular point-of-view.

In general, pretty much everyone in society as you pointed out in a great example who can solve a Sudoku puzzle, can form qualified opinions about data, so long as they keep an open mind. Most of these decisions though, focus on a small perspective. What's directly good for them, their family, their community, their church, their friends, etc. There is nothing wrong with this, and most people live happy, satisfied lives.

But sometimes their decisions have implications that don't directly affect them - such as throwing garbage into a local stream - but may have larger negative externalities on society. The water carries it away, and unless they have a personal connection to something downstream, it doesn't affect them anymore. Or what about someone who eats a lot of junk food and doesn't exercise? They seem to be happy, even though being obese leads to greater health problems, which causes health care costs across the board to increase due to more people having health problems. Do either of these make this person bad? No. In their point of view, their decisions are perfectly rational. But sometimes it's things like this where scientists, or their doctors respectively, need to give them a helping hand towards better decisions.

We're all human, we all make mistakes, and we all need someone there to remind us when we begin making bad decisions. And as long as we all remember to keep an open-mind that we may be unintentionally making bad decisions, and actually change on recommendations from their doctors or other experts, we're all fine.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Adam, your right cross missed ENTIRELY. You haven't heard of:
--bison
--buffalo
--water buffalo
or have you? Those are relatives of cows, are they not? That is, they are bovines. A cow is simply a domesticated bovine, is it not? Right cross meet roundhouse kick. Make sure you know the facts too.



You know, I do think all this is moot. There won't be any flooding that wipes out the entire world's population. However, Global Warming will occur in a BIG way (i.e. the entire world on fire) at some point in the future. I don't know when, I just know that it will.

How do I know this?

Genesis 9:11: "I establish my covenant with you: Never again will all life be cut off by the waters of a flood; never again will there be a flood to destroy the earth."

2 Peter 3:10b: "The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything in it will be laid bare."

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Can we keep the religious texts out of this? It can only lead this debate down hill.

I'm not saying having religious views are bad or that they can't be scientific, all I'm saying is this is probably not the best forum for such a thing.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

This is true. However, there are certain scientific views that are treated as religion. I do not name them, because you can easily guess what I'm referring to.

There are three things that are a bad thing to discuss around here: Religion, Politics, and any Science that is treated like either of the first two. Anybody who wants to talk about those would be best advised to use PMs.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I think we agree here. I was just making the point that "There are definitely some "amateurs" out there who have opinions that should be valued."


Here is the thing, I can produce graphs that show a much different picture (than the graphs that I removed so as not to increase the length, see your post if others are interested). I won't but they are in some of the previous links. The reason they are different is because we really do not have accurate measurements as we look back in time. For instance, there is evidence of warm times in northern Europe at multiple times (Viking settlements in Greenland that are only now being revealed, vineyards in England) in the past. Does this disprove any of the graphs? Nope, but it is worth pausing and considering.

You are correct that using only seven years back by itself would not be enough to throw out an idea for global warming. I was more stating it because it is something not reported.

The way I see it, the temperature since the late 1800's (and early 1800's) has been increasing at a rate of about 1 degree F per century. This is curious that it has been increasing for about 200 years, before the significant increase in carbon dioxide levels (which is only gone up significantly over about the last 50 years), don't you think?

In addition, the way the globe was expected to warm is simply not the case if it was caused by carbon dioxide. Is that conclusive to throw out all man made global warming theories? No, but it should cause a pause to think (and actually report this - that was one of the links, the missing hotspot). (Money, politics, science?)

Yep, you are correct, we use oil for LOTS of things. You probably can't go five minutes in a normal day without touching something that started as oil. To be blunt about volatility, prices are also volatile to some extent. In your list of energy, ethanol and biodiesel are dependent on the amount of crop. Wind depends on if there is wind and can never be a primary source of energy. In addition, the infrastructure cost is rather high. Same goes for solar, though putting it in the right spots general can result in a fair amount of consistency. That said, it is rather expensive to build and maintain. Hydro is great, but it comes with its own downsides for wildlife. I personally think we should transition to nuclear, but there are all kinds of political issues. I don't know enough about geothermal.

Regarding corn, it is another money and politics issue. Corn is about as bad as it gets for ethanol production, but the government won't inhibits/prohibits the use of sugar cane for instance. However, green algae blows everything else out of the water by orders of magnitude in oil/acre yields. In addition, it can be used in places not suitable for any crops. The technology is getting close as well.

I won't get into much on the economy other than to say, in my opinion, it was preventable if the government had done its job in the last twenty years and that the worst is still ahead of us.

I was waiting for someone to mention algae. I will say, this seems the most appealing plan yet.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I prefer the approach that if Global Warming was to arrive in a form similar to the Biblical Abocalypse, there's little we could do to stop it anyway so we don't have to consider that possibility

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

It doesn't take a rocket scientist to know that the cow population has solely increased because of man.
I have mentioned this before in completely unrelated conversations but in a lot of cases you would not see professional engineers doing what the same thing that the high school students.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

This phrase humored me. First, a rocket scientist is no more better at analyzing cow population then average joe. Secondly, the word "solely" seems to be a big over statement. We can't know all the reasons for something, thus you can't put full blame on us. Thirdly, you seem oddly focused on cows. There are other animals in the world. Some of which could be contributing to global warming.

I suggest you re-read Eric's previous post and take a step back on how you are posting here. You could use some work on your tone if you intend to be taken seriously.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Nope. I win. Stupid act on my part. I have no idea why I missed the EPA's website the first time. In fact if I actually interpret the EPA's data correctly (A BIG IF ON MY PART) it isn't even the biggest source of green house gasses.

Eric brought them up. I know better than that.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Not to mention dying organisms. CO2 is released as the bodies of organisms decompose. If you factor in all the leaves, grass, and other plant-life that decays come winter then you have a lot of CO2. Maybe not a climate change contributor, but something to keep in mind.

Something to consider: If evidence was brought forward that totally disproved human triggered global warming what would happen?

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Now that this thread is no longer even remotely about sunspots, let me plug an interesting documentary on this topic called "Crude : The Incredible Journey of Oil".

On the one hand, it is like the jr high science films that follow a single carbon atom around for millions of years showing the different things it does over time. This is interesting as it demonstrates some of the cycles in play.

Another interesting facet of the film is that it interviews many petroleum experts such as the man who made the initial discovery of the oil fields in Saudi Arabia. Many of the interviews discuss the projections for global oil production made by Hubbert in the 50's. It has a bias of course, but just hearing the luminaries in the field voice their opinion was cool.

It has a good summary of why the big oil fields are found where they are. The frequent algae blooms enhanced by runoff and into relatively stagnant gulfs acts as a recapture mechanism to deposit CO2 from the atmosphere and bury it over time in places such as the gulf of Mexico, the Arabian gulf, etc. The longer lived the sea, the more oil that will have collected over the millions of years.

Another element in the film is the explanation of what happens as CO2 levels increase, how the cycle eventually runs its course and eventually restarts. It describes how this has happened at other times in history, with volcanos responsible for much of the CO2 release, and it does discuss how the increased release of CO2 from industrialization indicates that we are moving ourselves along faster in this cycle.

Not being an expert in the field, I have no way of knowing its accuracy on every point, much less my accuracy in trying to summarize it. I thought it was good information accessible to reasonably educated viewers, and it covered lots of interrelated topics. It provided interesting topics for my father-in-law, a geologist and petroleum industry veteran, and myself to discuss.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

So why aren't we actually focusing on the bigger sources instead of putting fees on ranchers/dairy farmers for their critters' emissions by the head (or tail) to the point that they can't make a living? (Yes, that was talked about, as recently as this spring. I'm not sure of the current status of this.)

Oh, wait--landfills are necessary because we can't come up with better ways to dispose of trash that won't be complained about. And who is dumb enough to reduce the amount of oil and natural gas we use, because then commuting gets a LOT harder (unless we go back to the horse-and-buggy days). So we have to go after the cows, who can't help it, if we want to reduce methane emissions. And yet methane is only one greenhouse gas--and relatively short-lived.

Why not just harness the energy in methane by collecting, storing, and burning it? Reduces methane emissions, allows a slowdown in petroleum/natural gas consumption, and maybe even allows time for the atmospheric methane to dissipate a bit.

Now, as to whether humans are responsible for the increase of the cow population: Remember, bison are also bovines, presumably with the same problem--and yet, man is responsible for driving them almost to extinction. Think about it.

As for Mr. Pockets' question, I can tell you: whoever brought it up would be ridiculed and the evidence would be hidden away so that nobody would believe it. See Copernicus and Galileo with the heliocentric theory vs the Roman Catholic Church with the geocentric theory. Also note that at some point, the evidence would come out and people would accept it, and then the people who now say that it is caused by humans would be remembered as opposing scientific progress.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Yeah...it's sort of creepy to imagine what would happen if all of the scientists who currently form the "consensus" regarding global warming were remembered as "opposing scientific progress". Talk about promoting public confidence in the scientific community. :rolleyes:

Well if we're heading in that direction, the largest contributor to the greenhouse effect is water vapor, as it is the most plentiful greenhouse gas in the atmosphere...

I figure that I should insert a little disclaimer: I'm not at all opposed to the idea of reducing pollution, increasing energy efficiency, or developing alternative fuel sources. All of those are excellent uses of time and energy. I'm just not convinced that global warming is man-driven.

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

I'm not sure if I'm going to be able to find it anymore, but Arthur St. Antoine in Car & Driver magazine had a very good, well-thought, and well-written opinion regarding what was then known as global warming a couple years ago. If someone finds it before I do, can you post a link?

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Like the EPA...

Before you get all huffy about that comment, they're the ones who wanted to put the tax on cattle for their emissions, IIRC.

I knew the stuff existed, or had at least been talked about, somewhere in some dark corner of my memory that I don't go to very often. If that can be tapped economically, then all I can say is, nothing like a little recycling...

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Actually, before the turn of the 20th century, there were some pretty dire predictions about the consequences of horsepower (in the literal sense of the word). While your automobile produces a good deal of CO2, you never see it it just floats away. A horse, on the other hand, produces about 22 pounds of manure, per day, that gets left on the street. It doesn't mention how many horses there were, but authorities had to pull 15,000 dead horses from the streets every year (and by law you were supposed to remove it yourself, so there were definitely more of them). They figured unless something drastic happened, New York would be rendered unlivable by 1950. Luckily for them, a German fellow by the name of Dr. Otto was busy inventing the 4 stroke engine...

Re: Sunspot Minimum or "Is the sun going to sleep?"
 

Boy! I never thought this thread would get so far off course.
just to be a candle of hope in the darkness, when I was in China last year, I visited a rural community. The people there were proud of the fact that they were using methane from their farm animals to cook and heat. It removed them from the dependence on charcoal for cooking (and the pollution).
