As we leave the solar system radiation should decrease the further out we go.

Just no.

You are confusing Solar radiation with cosmic radiation... and they are largely very different things.

The "solar wind" is largely photons and other, relatively low-energy charged particles from the sun. (Note the word "relatively".) Which is GOOD for us here on Earth. Because cosmic radiation has a much larger component of HIGH energy particles. The solar wind interacts with Earth's magnetic fields in such a way as to shield it from the cosmic high-energy particles.

But it's the cosmic high-energy particles that penetrate far enough into the atmosphere to ionize particles of matter, which form nuclei around which clouds form. So... high sunspot activity generally means fewer clouds, which in turn means it gets hotter. When "solar storm" activity is low, more cosmic rays leak in, forming more clouds, cooling the weather.

Unfortunately, it is these high-energy particles which require the most shielding. And in general, cells are more prone to damage than radiation-hardened silicon chips.

Again total crock of shit. Australian Uranium export laws http://en.wikipedia.org/wiki/U.... Not only is mining totally and strictly regulated (no matter who the hell owns the mine, they can not even stick a shovel into the ground until approval is gained from local, state and federal government), it can only be sold to countries the Australian government has specific agreements with and is restricted to energy use only http://www.world-nuclear.org/i....

100% irrelevant to the topic I was discussing, which was ownership of U.S. uranium interests by Russia. Not only is Australia a completely different continent, its politics are also completely different. Similar in some ways, but definitely not the same.

It is the US government that is seeking to directly control the mining and export of 'AUSTRALIAN' Uranium because 31% of worlds resource and Australia already exports Uranium to China and the US. There are a whole bunch of Uranium resources yet to be touched.

Again, completely irrelevant to the topic under discussion. If I lived in Australia, I'd object to sales to China OR the U.S.... but especially China.

Nuclear is not the only solution, nor is it particularly attractive when solar can achieve the same goals, without the side effects.

How do you claim absence of side effects?

Solar farms are already observed to fry birds and blind pilots. Not to mention the huge amount of landscape they consume. And in high latitudes, not only to they take up even more (and more ecologically sensitive) area, they aren't even usable a good part of the year. In my area, they don't even come close to competing with other sources for cost.

This has been studied and the result was that there is a localized heating effect in a small area immediately downwind of the wind turbine which is rapidly lost in the noise of the already-chaotic system in precisely the same way that the butterfly effect is bullshit â" if an entertaining thought exercise.

This causes me to think you haven't understood what the Butterfly Effect actually is. It says that slight differences in the initial conditions of some nonlinear systems can have a profound effect on later outcome. It doesn't apply to all chaotic systems by any means, nor does it necessarily mean a persistent change... just a big one. Nor, just off-hand, would it seem to apply to your windmill example at all.

You might be interested to know that the Butterfly Effect has made a profound contribution to weather and climate modeling. Without it, we would not know even the relatively small amount that we do know.

The name "Butterfly Effect" was intended as an analogy to how it works... it isn't to be taken literally. But it does work, and is observed in the real world. If you doubt that, I strongly suggest you avoid flying in a modern jet.

If they don't know what they are doing, then why are they the leaders?

I disagree with others here. If they say they don't know if their organization has the talent to succeed, then indeed they don't know what they're doing.

Especially those who think their IT dept. is incompetent. What that means is (A) they are wrong, or (B) they are right... which in turn says they made bad hiring decisions and should clean house.

While this mostly seems like incoherent ranting -- pardon me if I am mistaken -- I was making a very simple point:

Let's say you, Sam, own a large farm. And somewhere on that farm, coincidentally, is a large deposit of naturally-occurring "Roundup". As long as it stays where it is, everything is fine. But if it got into your fields, your crops would mostly die.

You have several neighbors, many of whom are basically friendly to you. You also have one neighbor who also has fields, who directly competes with you. His name is Russel.

You and Russel both know that using Roundup on each other could kill each other's crops. So you have a mutual agreement to never use Roundup... but just in case the other guy does, you build up a pretty big reserve to use in retaliation. Just in case.

That pretty much describes the "cold war". And it wasn't irrational. It was stressful but it did work.

Now along comes some insane manager of your farm, who decides Russel isn't so bad after all. You, the owner (The People) know better, but that's the line your "manager" (President) is selling you.

Question: even though you are not actively in conflict, do you sell shares in your Roundup mine to Russel? Especially when you know he will in turn sell it to other neighbors who are even less friendly?

It would be IRRATIONAL to do so. It would be BETRAYING your farm and your family.

But that's just exactly what the Clinton Foundation helped do.

It's not fucking rocket science. Nor is it paranoia.

You're right, it was 24 years ago. I guess my mistake reflects just how much trouble I go to, to pay attention to your lengthy rantings.

they predicted that Antarctic sea ice would increase in a warming world

But they DIDN'T predict growing sea ice in a world that is NOT warming, did they? (I did read the paper, by the way.)

The models havenâ(TM)t predicted one thing, in 30+ years. ... You donâ(TM)t really need to know anything about the science except that IT HASNâ(TM)T PREDICTED ANYTHING. That makes it bad theory. ... CO2 warming theory has predicted NOTHING."

Since these conditions are not the conditions presumed in the model, in fact they have not predicted anything. You are just a master at inappropriately shifting contexts, as I have pointed out many time. You don't get to say that they predicted a result given THESE conditions, then say the same result under OTHER conditions constitutes a "prediction". Especially given the uncertainties involved. That's bullshit.

Good grief, Jane. Once again, I'd rather use all the available data

You aren't using "all the available data". Once again, you are using the data that is convenient to you. I will ask you again: would the slope be the same if you chose 2000 for a starting point, or 1850?

No, it would not. I made a simple comment based on a simple fact: 1981 was at or near a local maximum, and using it for a starting point of your "average" is questionable at best. That is an accurate statement. If you chose 1930 instead, as another local maximum you would again have to justify that as a starting point. You don't get to weasel out of that.

In a broader context, a single dataset is just part of the picture.

Yes, indeed. If you should ever start actually using "all the available data", and were honest with yourself, I think you might start softening your tone.

Manabe was 14 years ago. Conditions have changed rather significantly in that time, as has our understanding of the geology.

It may be that Manabe is still correct. On the other hand, it may not.

I've told Jane and economart that Fig. 2(a) from Polyak et al. 2010 shows that the reconstructed Arctic sea ice extent in the 1930s was comparable to that in 1979, and the modern decline is quite clear.

You seem to feel that what "you told people" is necessarily truth. That's an interesting point of view.

I've also repeatedly explained that Jane's accusations of deliberately misleading cherry-picking are completely backwards. As usual.

You are implying that my statement that 1981 was near a temporal local maximum is incorrect?

You would rather use 1930 as your starting point? As opposed to, say, 2000 or 1850?

Ultimately, the liberal philosophy is that society can and should take care of everyone. The libertarian philosophy is that everyone should only be required to take care of themselves. From an antagonist perspective, liberals have their heads in the clouds, and libertarians have never heard of the tragedy of the commons.

No, like so many others you mischaracterize what Libertarians are all about.

Regardless, the Tragedy of the Commons stemmed from a socialist "commons" policy... nothing even remotely Libertarian. In a Libertarian society such commons would scarcely if ever exist, and if any did, no party would be allowed to exploit them at the expense of others.

I think your analysis is off. I believe democrats see government is a moderation of society, where people come together to create a better society and life for EVERYONE, not just the few wealthiest fucktards that will buy them into office (as the republicans believe), or that only-the-strongest-and fuck-everyone-else as conservative libertarians do.

The first thing to note is that you are confirming my own comment, to a rather laughable degree.

The second thing is: you prove your ignorance by speaking of "conservative libertarians". There is no such animal. There are libertarian-leaning conservatives, but it does not work the other way around.

As for the big government democrats, maybe you need to do just a little smattering of research before continuing to use a stupid talking point that is basically propagandized projectionism utilized by con men preying on the willfully ignorant conservative base.

And maybe you should learn something about people you are speaking to before assuming they are just repeating media talking points. In fact I was speaking strictly from personal experience, much of it gleaned from right here on Slashdot. From comments like yours.

The largest state governments by percentage of population are red states:

Yep. Because people are sick and tired of "Progressive" liberals and their provably failed policies. I mean not just failing now, but that have historically failed, for many decades.

But on the other hand, the largest single voting bloc (>40%) are people who identify themselves as "independent" or "libertarian". In other words, not members or followers of either of the "Big 2" parties.

Maybe the biggest reason for the hatred is, libertarians and republicans continue to push policies that simply DO NOT WORK,

How do you know? Again you confirm my original comment by conflating libertarians with conservatives (a false notion), and then go further to suggest that YOU HAVE EVER SEEN A LIBERTARIAN POLICY. That's a hoot.

Just a lot of really bad arguments.

To me, the worst of the lot is the statistical "reasoning" which is all based on the presumption that these events are equally distributed. The thing is: we know that they are not uniformly distributed... and even worse, we don't know how they are distributed.

Sure, we do know of a few particular cycles of tendency, but those don't predict individual events.

So the very basis of TFA's statistical reasoning is nonsense. We don't have any way to actually calculate the probability of such an event. We don't have enough information.

Correction: arctic ice is below 1 standard deviation from 1981-2010 average, but within 2 std. deviations.

Still, remember that 1981 is a (dare I say deliberately chosen?) high point from which to start measurements, so going by the 1981-2010 average is probably a bit misleading.

And the total global ocean ice is still well above normal, because of the record high Antarctic ice right now.

I've not really followed Antarctica. However, back in the 80s I'm pretty sure it was "tens of millenia to melt all of Antarctica if it's possible at all". More recently I've seen comments along the lines of "It can't happen in less than 5-10 thousand years" with the assumption that it will happen eventually if we continue dumping CO2 into the atmosphere.

Currently, global sea ice is well above normal. That is largely because antarctic sea ice is at or near a record high, while arctic sea ice is slightly lower than (but approximately within one standard deviation of) average.

Now, while I know that overall ocean temperature and surface ice may not be a direct correlation, it's a bit of a mystery to me how they can claim that ice is melting due to unusual ocean warming, when we know that ocean surface ice has been at record levels.
