Geoengineering
We can dump iron in the oceans as a fertilizer which produces bigger fish harvests and sinks co2.
https://en.wikipedia.org/wiki/...
We could use calcium too.
https://www.technologyreview.c...
https://www.wired.com/2008/07/...We could farm Kelp.
https://www.scienceforums.net/...But unless we stop emitting co2 this will not be enough. We should really consider Thorium reactors especially if they are as safe as scientists are claiming.
https://www.nextbigfuture.com/...Sorry about the quality of the links but it should be a good starting point for some research. None of these by themselves will be enough but we have many options even terrible ones like reflective aerosols.

Re:'Muricans are too stupid to do this.
Of course we haven't figured it out. Too many goddamn hippies tell us that we need to preserve the pristine nature of the area... so we made it a park and forbid any serious effort to try to poke around at it and make any useful headway.
Then you have morons like the guy on scienceforums.net that says "The idea is like trying to put a pin into a balloon to let just a bit of the air out." Idiot doesn't realize that there is a way to do just that. Put a piece of tape on the balloon; poke a hollow needle coupled with a valve into balloon through the tape; have as much control as the valve allows to let the air out slowly without bursting the balloon. Using science it'd be easy enough to figure out a method to tap the volcano and bring it under control for man's usage in much the same way.
There's all this talk of making America great again as a leader in business and scientific innovation, but it just isn't going to happen until we get over this fear of death and killing thing going on right now. You can't make a damn omelette without breaking a few eggs. Likewise you can't make meaningful progress without killing a few people in experimental ways. Case in point, how many test pilots died as we tried to figure out how to get into space? How many people died from the effects of radiation exposure and gave us a better understanding of nuclear technology from it? How many people died in the construction of the various skyscrapers that dot the oldest American cities? True progress can't happen without the deaths to learn from.

Re:size?
you do realize interstellar transport is impossible right? even if you use atomic metals to power it it would take roughly a third the power of the largest atomic bomb to accelerate 1 kilogram of mass http://www.scienceforums.net/topic/34180-energy-needed-to-reach-99-c/. to accelerate and then decelerate from light speed is unrealistic. not to mention the problem of needing working force fields, as hitting anything is the same as a http://en.wikipedia.org/wiki/Relativistic_kill_vehicle without force shields nothing works, and again you'd need all the uranium in the whole solar system to speed and decelerate a small ship with humans on board, or perhaps send machine grown clones at the end of the journey to save on power consumption.

Re:Courtesy of the Sun
I was waiting for something to happen after hearing about the massive solar flare yesterday, but nothing this big.
And how is that supposed to work?
Well, I thought this was a more accepted concept than it is, but I guess not.
For your reading pleasure:
Change in magnetic field: an early warning system to understand seismotectonics
Universality in solar flare and earthquake occurrence
Earthquakes, Solar Flares, and Solar Wind Anaylsis
Whether solar flares can trigger earthquakes
Hopefully, that'll shed a bit more light on this growing theory for you. I don't think anyone is saying that every earthquake is caused by CME's, but when you have massive ejections like yesterdays they can certainly contribute to instability in the Earth's magnetic field, which leads to tectonic shifting.

Re:Wrong power
Yes, it does apply. Laser light is subject to the inverse square law like any other light.
Not according to posts (below), summarizing:
The inverse square law applies to light radiated in all directions. The reduction in intensity is because the same amount of light is covering an ever expanding area. With a laser, you're sending the light in a straight line (theoretically, at least). The light beam covers the same amount of area 10 miles from its source as it did when it first left the laser.
The inverse square law applies only to isotropic light sources. A laser is highly directional and thus does not obey the inverse square law.

Re:Compression
"Sensels"? There's no need to invent new words. The word "pixel" means "picture element" and is relevant whether discussing monitors or CCDs. Stick with accepted terminology.
sensel. Not my invention, I assure you.
Pixels emit data. Pixel is a neologism coined from picture + element.
Sensels collect data. Sensel is a neologism coined from sensor + element.
They're not doing even remotely the same task. Consequently there is a practical reason to discriminate between them. If you are under the impression that anything arranged in a grid that does anything with light, regardless of task, is a pixel, then I suggest you get over to Wham-a-lart and ask them for some linoleum pixels and see what that gets you.
If this aggravates you, I'm sorry. Language evolves despite the digging in of your heels.

Re:I wish
Right because upgrading Linux installations always works every time.
Not every time. You may have broken hardware, or you may erase half of distribution after installing it. Then it won't work.
Umm, you mean you try it and it fails and Linux apologists tell you you have broken or hardare or RTFM. And then you waste ages trying to find someone who actually knows what they are talking about.
Linux is about progress, not back compatibility and no one is willing to do the work to maintain old ABIs or filesystem formats. In fact they often deride Microsoft for caring about it.
In fact, you know absolutely nothing about Linux. ABI changes very slowly, and older versions will work with modern kernel, and may require old libraries that usually are provided in "compatibility" package for this very purpose.
Hmm, that's ok if someone bothers to do it. Otherwise you need to do it yourself. And my point is how many people are going to get it right for a 13 year old disti.
E.g. Firefox 3 won't work on Fedora Core 4 which is a lot newer than 13 years.
http://www.scienceforums.net/forum/showthread.php?p=417678What Microsoft does is different -- it has SHITTY OLD INTERFACE, and it continues throwing shit into the newer and newer versions of its OS supposedly to provide compatibility with old shit, but really to avoid making any progress toward anything better. Instead of deprecating obviously bad systems such as most of Win32, everything new is either added or built on top of it. The reason for it is very simple -- it's very difficult to provide a compatibility layer on another platform that will imitate extremely bad, poorly designed, bug-ridden subsystem in a way that will support all "creative uses" and workarounds that accumulated over decades of evolution of such a massive engineering failure. If Windows wasn't that bad, Wine (or Windows interface under OS/2 before it, or Wabi,...) would be orders of magnitude more simple, and it would become "better Windows than Windows". With Windows being full of unmaintainable finicky crap every imitation of it necessarily has to be full of unmaintainable finicky crap.
You say shit a lot. But it's sort of interesting that I can run Firefox 3 on Windows 2000, which is a lot older than FC4.
And that's because of all the work people like Raymond Chen do on making sure that software works after an upgrade. Because Microsoft want to sell you that upgrade. In the FOSS world no one gives a shit because there's no money in it. If some developer does some refactoring that inconveniences a user, the user goes to the community which is full of people like you yelling that they are idiots and the sort of work Raymond does is shit. That's why Linux has negligable market share
http://marketshare.hitslink.com/report.aspx?qprid=10
Hmm, doesn't that seem a bit of an ad hominem attack to you? Even if it were true how does it affect what I'm saying.
You and other Microsoft defenders have literally flooded this discussion with your comments. Obviously you are trying to create an impression of validity by posting large number of comments with unsupported claims instead of participating in a discussion.
I just like trolling people like you who will defend Linux without knowing anything about how much work good commercial companies put into migration plans and ABI stability. No one cares about that shit on Linux. If you want it to work you need to reinstall a new OS every few months.
If this is true, please tell me what embedded systems are. Then I will know what to avoid like plague because it's made by a person so hopelessly

Re:treat the host poolYou see this is when it starts to sound ridiculous as the notion of 'vaccinating bats' seems funny at best. After all, how do you get the bat to sit still?
But the point remains: "Nature will find a way" ie mutation will occur and it will occur in the host.
The goal should be filovirus eradication and vaccinating humans will not acheive that. Therefore, spending money (a lot of money) on only one part of the problem is a mistake.
But why is so much money being spent?

More Titor quotes and predictions
Heres some of the most convicing quotes. Attributes goes to crims on scienceforums.net.
Remember these quotes were made in the early 2000-2001s, before 9/11, Patriot Act, Iraq-war, etc: http://www.scienceforums.net/forum/archive/index.p hp/t-19841.html
These following predictions by John Titor were the most convincing and made me think he could be real:
"Real disruptions in world events begin with the destabilization of the West as a result of degrading US foreign policy and consistency."
"In the grand scheme of things, the war in the Middle East is a part of what's to come, not the cause." [This was posted in November 2000]
"I'm glad to see it's so easy for [you] to dismiss the Middle East. Yes, I suppose it is a no brainer but pretty soon it will be a "no armer" and a "no legger". [Nov 2000]
"I believe they [China] are pretty close to putting a man in orbit. It shouldn't surprise you if they do that soon." [Late 2000/Early 2001 - China put a man into orbit in Oct 2003]
"Are you really surprised to find out that Iraq has nukes now or is that just BS to whip everyone up into accepting the next war?" [Late 2000/Early 2001]
Plus he said there would be a woman president in 2008 (Condi Rice or Hillary?)... which would make sense for Condi, since she's an expert on Russia/USSR and John Titor predicted Russia would nuke USA in 2015...
My most memorable Titor-quote is:
"Are you really surprised to find out that Iraq has nukes now or is that just BS to whip everyone up into accepting the next war?" [Late 2000/Early 2001]
How could he know that so early, even before 9/11?
Heres more predictions from: http://www.bbc.co.uk/dna/h2g2/A6345407
Besides the American civil conflict and a third World War Titor made a number of other significant predictions:
*
America will wage war on Iraq, claiming Iraq has nuclear weapons. Titor made this statement years before a war with Iraq was considered. He also claimed no weapons of mass destruction would be found.
*
War will erupt between Israel and its Arab neighbours, and weapons of mass destruction will be used.
*
Korea, Taiwan and Japan will be annexed by China as the West becomes unstable.
*
In the early 2000's CERN will lay the foundations for time travel. In the autumn of 2001 after Titor had left, CERN released a statement indicating the creation of mini black holes was possible.
*
Mad cow disease will be a health issue in America but it will be under-played.
*
Genetically modified food will be used to produce hybrid seeds that will have detrimental effects on the population's health.
*
Titor made a number of statements about constitutional and civil rights in America. He also said the American government will assume its citizens will prefer security over certain personal freedoms.
*
The future will judge the present harshly.
Maybe not all will come to pass, but his way of writing is very convincing. We CAN do more than just hope though. We can start with ourselves, and raise the global spiritual awareness. Service to one another is the greatest thing any human can do in her lifetime. -
Original research
I brought this up over at ScienceForums yesterday, and someone pointed to the mentioned article that says: "They wrote up their results in the 29 April 1999 issue of Nature, but I've been unable to find it online."
The original article that particular blog is based on can be found here
Abstract is here
and full text (HTML and PDF w/ images) for those without access to Nature is here
However, this research was done on words that are reversed, not internally scrambled. I have been unable to locate research on the letter order within longer words, however the principle is accurate and I'm sure it exists. -
