So if there's less ice, it's because of global warming. But if there's more ice, it's because of global warming.

Yes. There is less ice in some areas due to global warming and more ice in other areas due to global warming.

Think of it this way: Imagine the entire planet heated up by 20C, we wouldn't expect to see any permanent ice outside of Antarctica. (The North Pole might get some seasonal ice, but the much warmer oceans would melt it fairly quickly.) Now, with all of the oceans that much warmer, think how much additional water vapor would make it into the atmosphere. When the additional water vapor ends up over the South Pole, it will be cold enough for it to freeze and fall as snow. As the snow accumulates, it compacts into ice and we end up with a LOT more ice at the South Pole.

So: Less ice everywhere but Antarctica due to global warming, but a lot more ice in Antarctica due to global warming.

(And, yes; I do realize that this example is a vast simplification - and overstatement - I just used it to illustrate the point.)

It absolutely does not matter who has your PUBLIC key. The entire point is for the entire world to have it. Now, the PRIVATE key - that you need to keep to yourself, and as secure as possible.

Note: I say "as secure as possible" because, at some point you are trusting an underlying layer to be doing their job correctly - be it browser, email client, PGP application, OS, or that rootkit that got installed.

Your error is in assuming a simple, isolated system and ignoring the complexity of dealing with the horribly analog world of biology.

In general, there are two considerations for when, and how much, plants grow. The first is the amount of sunlight they receive (hours per day) and the second is the number of "degree days". Since duration of sunlight isn't going to change (at a certain latitude), let's focus on "degree days" first.

A "degree day" is based on the temperature of the day, so the higher the temperature - the higher the value. However, there are bounds for this. For example, corn needs at least 50 degrees Fahrenheit, but not more than 86 degrees Fahrenheit. i.e. - Below 50 means "0 degree days" and 92 will be the same number of degree days as if it were 86.

The problem comes in when it is far too warm which, for corn, comes in around 86 degrees. The plant hasn't adapted for growing in temperatures much higher, and will shut down growth; much higher temperatures will even cause damage to the plant. Here is a human analogy - a human might be able to run really fast and really far but, if it is 115 degrees outside, that isn't going to happen and any activity may result in heat stroke. A plant will be stressed in this kind of heat and will actually be damaged. In this way, too much heat will cause plants to grow less, and we will have lower yields.

However, since plants also depend on certain amount of sunlight, it isn't a simple matter of moving things northward (or southward in the Southern Hemisphere) to match temperature. All of the plants are also expecting a certain duration of sunlight. This isn't constant with latitude, so moving the plants north will reduce yield. (And more sunlight doesn't mean higher yield - plants also do things at night like release water vapor.) This means that we will have to reengineer our crops to match new conditions - which will take decades. (And crop genetics isn't a simple matter - companies spend billions on trying to make better species.) So, until we do that, we will have lower yields.

Also, many plant diseases like the heat (or like that they don't freeze to death in the winter - see Asian Soybean Rust ranges) - so they will enjoy millions of square miles of new territory - increasing the cost of production (herbicides and pesticides) and, since bugs and molds eat the plants, will give us lower yields.

The other problem is related to economics and infrastructure. Farmers have certain equipment to plant and harvest the crops native to their area. Plus, their fields have been designed for those certain crops. For example, they may be terraced in a certain way or be designed with a certain level of drainage based on existing weather patterns (temperature and rainfall). Renovating millions of square miles of farmland is going to be expensive and ridiculously time consuming and until it is modified to match new, prevailing weather patterns, will contribute to lower yields.

The other side to the economic coin is that decisions are not going to be made on a 50-100 year strategy. To operate next year, a farm needs to turn a profit this year. So, they aren't going to completely retool if yields go down 10% - it would make no sense. The capital costs would dwarf any profit from the new crops being put in. Therefore, they will operate at lower capacity and accept a lower profit - since it is still a profit. Sure, we will get changes when push comes to shove, but that will take decades as climate change forces them to change. Until that point - lower yield.

Moral of the story, we are looking at decades of lower yields as climate change really kicks in.

But that's the problem - Bitcoin isn't "real" money. If it were, there would be a huge number of regulations to follow, sinking it as an anonymous currency. However, if it isn't "real" currency, thefts and/or fraud will not be investigated by law enforcement agencies. So, pick what you want: An anonymous currency with no support of law enforcement, or a "real" currency where regulations such as requiring a photo ID to open an account apply.

I don't see why archival storage should be much different. You should have at least two copies of everything in different locations, on-site and off-site. Basically, if you're shoving archival data in a third-party facility like this, you have no backups of your archives...

I'm guessing they only keep a single copy of 13-year-old data because the cost/perceived value equation says they don't need multiple copies. I mean, how often does someone pull up detailed business data that hadn't been used in that long? (Summaries and stats, sure. But the detailed records themselves? Practically never.)

I've used online dating sites, and found them quite effective. My girlfriend of over 2 years and I met on an online site. A close friend of mine met his wife on an online site. So, they do actually work.

I remember when I gave that idea a go and found I generally sent out tons of emails but rarely got any responses.

This probably means your emails sucked. Did you send a one-sentence email? Something like: "I saw your profile and you seemed interesting so I thought I would say hi." Where was your effort? If you want to meet someone, you need to demonstrate you are interested. Did you point out your similarities, common interests or things you both enjoy? You need to show that you aren't just some random guy spamming a hundred girls to see what will work. Does she have a cat or a dog? Even if you don't have one, you can mention that you used to, or you've wanted one, or ask how much the darn thing sheds. Just something showing it's personalized and, most importantly that you read her profile.

While I have met people online, I've definitely found my chances are significantly higher in person, face to face.

Again, that's probably because your emails sucked. There is no tone of voice, no body language or dimension to an email, so you have to do it all with words. This isn't easy, and a lot of people suck at it because they've never had any practice. However, most people (although not all) have a lot of practice interacting with people in real life - even if it is just to order something from Starbucks - making them better at communicating in real life than in an email.

If I were to become single again, I would be back online right away. It's a fast way to find people who are interested in similar things, and to meet a lot of people that you wouldn't in your regular routine. (When was the last time you went to a coffee shop on the other side of town just to see if you could meet someone new?)

He is responsible for enforcing the law. (Or not.) If Congress objects, they can impeach him. However, within his bailiwick, he is the supreme authority.

It's how the checks and balances of the three branches of government work. None is beholden to the others, but they can be stopped, blocked or removed by the others.

And while tuition is going up, technology has driven the prices of course materials down significantly from the old days, when you were stuck with the single College bookstore selling at full price.

You aren't paying enough attention to textbook prices - or tuition. The rapid increase of tuition is far more than a full set of books would cost. Even a bad semester would be less than $1k of books, and tuition is going up by double digit percentages every year. In addition, while you can get a deal on some textbooks, the publishers are out to maximize their profits and spin new editions, or make sure there are shortages of old editions to offset the difference. Plus, sending free copies of the new editions to any professor who uses them in their class is a nice way to make sure used books are a dead end.
