Yes there are more sources. To quote wikipedia: " Quantities such as tree ring widths, coral growth, isotope variations in ice cores, ocean and lake sediments, cave deposits, fossils, ice cores, borehole temperatures, and glacier length records are correlated with climatic fluctuations."
These other proxies agree with the tree ring data from about 1600-1950. Before that time, we have too little data to use the tree rings for this purpose in a sensible way, and after there is the famous divergence problem. . It is, of course, simply a matter of some other limiting factor for tree growth in the Northern hemisphere. It is an interesting problem, of course, but not for global warming, as we have much better records from direct measurements before 1950.
And for the record, I'd hope that the global warming wasn't true, but it'd be a vain hope. I prefer the facts over what I wish were true.
The downside for solar is primarily cost, and the land used. Also, for non-Si-based cells, which is most of the high-efficiency ones, you'll be using expensive and/or toxic materials in production. Finally, they do not produce electricity at night, so either you will have to supplement the power generation by something else (wind, gas, something else), or you'll need substantial storage.
None of these problems are unsurmountable, but neither are they trivial.
Sorry if I came off as rude, I thought this was common knowledge. The electricity generated by the solar panel will be used somewhere, and in the process, be converted into heat. In other words, the electricity is temporary. The motion in the motors you mention will eventually be converted to heat (perhaps in brakes, or in tires); the light will eventually be absorbed by materials in e.g. a building. Admittedly, a tiny fraction of the light might escape earth, but mostly it will dissipate as heat.
Heat is sort of the ground state for energy: sooner or later, every form of energy degenerates to heat. I could give you the full lecture, if you wanted, but I am going off a limp and guessing that you would prefer the above 1000-feet explanation.
For the pedantic then yes, in principle you could use the electricity to, say, generate sugar for CO2 and bury it deep, thus postponing the eventual release of the heat for a (possibly long) time. I don't believe that will be a major activity, though;)
Because there are more sources showing the same picture. I don't know why the points stopped matching in the 1960s, and I do not know that anyone do know. If it bothers you, leave out the data: You will get the same picture anyway.
Except that the temperature did not stop rising in 1998. 1998 was just a very hot year. Check the graph yourself, you don't need advanced statistics to see that 1998 was no turning point.
Worrying about using up our Si-resources is a bit silly. As for the panels, they would go to whatever we are going to do with the roofs.
The bit about worrying about the "Less sunlight reaches the Earth and heats it" is similarly silly. Whatever energy we extract, it will convert to heat. And the panels will likely go where there is little plant life anyway (like roofs).
Technically, it is not necessarily so. E.g, windmills (on land) have about the some lifecycle cost ($100/Mwh, according to wikipedia) as coal or nuclear, not counting external or subsidiaries. They, of course, suffer from the same as fission: too few wants to live near a windfarm. Hence, much of the world subs expensive energy production (e.g. offshore, solar). At least, that is the case around here (DK).
The wildest prediction would not submerge Denmark... for instance, I am about 50m above the surface of the sea.
The capital Copenhagen, now, would be possible, at the central parts. But as we are set for a few-metres-rise-by-2100, even most of Copenhagen will be above-sea-level. At worst, it could be a new Venedi with bad weather and international cuisine.
Not sure if I count as an advocate... but I am thoroughly convinced. And all for nuclear, given proper attention to the hazards of fission-based energi. Fission isn't going to be the only source of power any more than wind is, though, it's not flexible enough --- unless of course we develop a way to store energi in large scalas.
You can only copyright an expression of an idea, not the idea itself. So the list of ISO country codes --- not much to copyright there. The format, how the table is set up, perhaps, if it isn't done too generically.
No, you are not. You could even compile your own list of country codes (from wikipedia, e.g.), and publish it. What you cannot do is to buy a copy of an ISO standard, and print out 10 copies for your friends.
But yes, I too wish it wasn't so. That would in practice mean that the price of being a member of ISO for a country would have to rise significantly, with the obvious consequences.
In this country (DK), how say a contract or agreement is formed has no bearing on how binding it is. Vocal agreement are just as binding as signed with witnesses. However, if the parties afterwards disagree, it certainly helps your evidence to have a digitally signed document ---though it is (I think) impossible to prove that you did not first steal the private key.
In most countries, denying that you signed something is raising the stakes pretty far if you lie. That is what holds the system together. The point of a signature is to signify that the agreement was made. You can actually sign with an X, or another mark if you like. At least around here.
If you deny signing something that you did, or if you forge a signature, you are facing a much more serious penalty if caught.
It is not so simple. The medical assistance in the US is far superior to the ditto in Norway. Not to dismiss the blessing of socialized medicine, but there is a price.
I am, by the way, living in a country with socialized medicine, and I am in no way a big fan of the U.S.
It is not quite so simple to get access to a TCP/IP connection. You need to be listening at the right (and relatively few) wires. It's not as if you are broadcasting to the entire internet. In fact, the easiest points of access would be whatever email gateway the 2 companies uses, either by physically hooking up on the wire or cracking the servers.
You just need to buy the right scanners. The one in our office has an address book, and you can just send/type in an email. Doesn't sync with google to my knowledge, but typing in an email address is only slightly worse than typing in the phone number.
When we get IPv6, you could even imagine being able to the scanned copy directly on another printer, though avoiding spam and similar will be an issue (as it is with faxes today).
I heard that in the 80's when everyone started outsourcing their manufacturing to Asia, A society based on Mental Labor as you put it, or Innovation and creativity as they put it back in the 1980's really has worked out well for us hasn't it ?
What always struck me as odd in that is that there is no reason why Asia could not learn the innovation and creativity skill. Really, what will happen (and is happening) is that the Asian and Western standard of living will slowly harmonize, and thus equalize the labour cost. Somewhere along the road, more poor countries will stabilize enough to start on the same road. In other words, in time, China will also be struggling with poor economic growth and burgeoning public spendings.
Unless some major disaster/war strikes, of course.
Where does it say you cannot say 1/3 meter? And certainly, saying 333mm for 1/3 meter implies too much precision, even 33cm would be off. Unless you really meant 1.00 meters.
I always find this argument a bit off. There are tons of stuff I don't know much about, and it never caused me any anxiety. Why is it that only the center octave can be turned by using a tuning fork/machine? What is the chance earth is hit by a largish meteor, or how often do people in my country get hit by lightning? Will I get hit by a bus tomorrow?
For my money, religion is mostly cultural. Sure, the seed is doubt, anxiety self-delusion and all that stuff. And sure, it grows because some people knows how to exploit that to get indoor jobs with no heavy lifting (as a famous author put it). But mostly it is a delusion transferred from parents to their children, and more general from society to the next generation.
Don't get me wrong, specific anxieties can be cured by dispelling ignorance (lightning is not caused by demons, e.g.) But there is no requirement to know everything in order to avoid ignorance, nor do complete possession of available facts dispel all anxieties.
They were showing charts and graphs and manipulating them. A few things that they did were zooming, drilling, slicing, etc. They were not looking at text and tables.
I wonder, were they avoiding text because text were not relevant, or because it was too cumbersome on the pad?
As for the wine list, yes, a restaurant could print a new wine list every few minutes but how utterly impractical is that?
Very practical. When a table is taken, you press a button, get a fresh sheet of wine menu, and puts it on the table when you greet/seat people together with the welcome snacks. Much better than having to log around a 'pad, and you can leave the paper with the customer without fear of someone stealing the menu, if they want to peruse the list a bit. I know what I would pick:)
Just like I could haul my desktop everywhere I want to do email but it's far easier to use my smartphone.
Ah, but the smartphone is significantly smaller. it fits in a pocket, unlike a 'pad or notebook, which fits in a small bag. I can see the point of smartphones, though I don't currently own one. 'pads, on the other hand, just seems like a notepad with a touchscreen instead of a keyboard.
I just cannot see what a 'pad can do that a notebook cannot do better.
Think more about advantages of form factor instead of tech specs and you can probably come up with a few use cases.
I don't even know the specs, I assume their are about the same as a notepad/small laptop.
I've seen some business men discussing a report and passing an iPad around manipulating the charts and graphs. While you could do that with a laptop, it's a bit more cumbersome.
Bit more cumbersome for the graphics, perhaps, but a bit less for the text and numbers. Throw in a mouse, and the notebook wins on both counts. That is a weak usecase.
I know that some high end restaurants have started to use them for their wine menus. The advantages I can see is that their wine lists are up to date and a tablet is less cumbersome than a laptop and more readable than a handheld.
Again, I suspect this is the show-off effect. A good printer and roughly the same software would give you paper-menus, which would be lighter, more durable, and disposable, while being up-to-date as of a few minutes ago. And lets not forget, cheaper. And again, this usecase is so special that I could draw upon my "tiny minority" argument again.
I actually have come up with a usecase: Inspectors might have a use for the form factor, using them to check off lists and stuff. When walking around, the lid can be a bit in the way, and the inspector would only need a limited amount of text input. But again, this is a really tiny minority usecase.
Heh. Ok, I had not thought about that usecase, I freely admit. Though I wouldn't trust any of the music stands (except a conductor's) to protect the 'pad.
So, yeah, maybe that could work. If I were composing myself, or if music sheet publishers suddenly decided to get on to an electronic format that could compete with the paper equivalent (e.g., not Adobe's DRM epub monster). But now we are REALLY talking a tiny minority.

So does mine, so I can print on my printer at home or here at the company. But, it's hardly ubiquis yet.
My DNS is also signed and ready for DNSSEC, if that helps :)

Most thermometers cannot even measure the (absolute) temperature to within one K/degree C without careful calibration. So that is kinda moot :)
