Pull my finger! Scientists solve knuckle-cracking riddle
Not quite "Nobel", but.. http://tech.mit.edu/V129/N41/ignobels.html
I believe someone won a Nobel prize for spending several decades of his life cracking the knuckles of one hand and just that one hand every day to see if there are really any negative effects from knuckle-cracking.
In his case there weren't.

Real Time with Bill Maher: 2016 Billionaire Buyers Guide
Dribble.
On the democrat side all there is is Warren. Hillery won't run. Her utter failure at the state department and the fact that she is married to pedophile Bill will keep her out.
I do agree that the republican party is filled with losers. Mit has the best chance. But leave it to Republican leadership to loose the election.
As far as Billionairs buying / swaying / influencing elections and all the left is bash the Koch brothers. - When will the medial look at truth?
The left are buying the elections, not the right.
For the 2014 election
Thomas Steryer gave $74M to the democrats
Koch brothers gave $2.4M to the Republicans.
Even George Soros ($3.8M) gave more to Democrats than Koch.

Beats me, I figure if a scientist from MIT does it with dry ice it's for a reason.
The police officers could be heard yelling stop resisting ;)
Definitely not irrelevant. I was just reading an article from MIT where they were able to extract audio from film footage that did not have an audio source. If we really need to hear what is being said in that cop car we could always have MIT extract the audio from the source file - it'll have artifacts but you would be able to hear exactly what the cops are saying in that car.
Radar Images Showing Planes Avoiding A Storm
Having just watched the first Air Crash/Mayday episode again (American Airlines, Flight 1420) I'm rather glad to see that
They reported a study from MIT that found that the aircrews were more likely to fly into a thunderstorm at night, if they were running late, or if aircraft ahead had gone through the same thunderstorm. (Rhoda, D.A. and Pawlak, M.L., 1999).
Bill Nye: You Can’t Ignore Facts Forever
@dannym3141, I understand that you are "stepping out of the debate," but, for your edification, I'll respond here... And, for the record, I am not "funded" by Big Oil, Big Coal, Big Solar, or Big Green. Nor am I a professor of climate or environmental science at a State University (and don't have a political agenda around this issue other than to help promote sound reasoning and critical thinking). I do, however, hold a doctorate and can read the scientific literature critically. So, in response to what climate change "believers" say, it's worth noting that no one is actually taking the temperature of the seas. They simply see sea levels rising and say "global warming," but how do they know? It's a model they came up with. But far from certain, just a theory. Like Antarctica melting, but then someone finds out that it's due to volcanic activity underneath, and so on.
And also, why is the heat then staying in the water and not going into the atmosphere? So, they then have to come up with a theory on top of the other theory... So the heat is supposedly being stored deep below where the sensors cannot detect it. Great. And this is happening because...some other theory or another that can't be proven either. And then they have to somehow come up with a theory as to how they know that the deep sea warming is due to human activity and not to other causes. I'm not denying that any of this happens, just expressing skepticism, meaning that no one really knows for sure. That folks would "bet the house on it" does not serve as any proof, at all.
The discussion on the sift pivots from "global warming" to vilifying skeptics, not about the original skepticism discussed, that there is catastrophic man-caused global warming going on. Three issues yet to be proven beyond skepticism: 1) that there is global warming; 2) that it is caused by human activity; 3) that it's a big problem.
When I ask about one, they dance around to another one of these points, rather than responding. And all they have in response to the research is the IPCC "report" on which all their science is based. And most if not all published "believers" say that the heat "may be hiding" in the deep ocean, not that they "certainly know it is" like they seem to claim.
They don't have knowledge that the scientists who are actively working on this do not have, do they? It's like the IRS saying, "My computer crashed." The IPCC says, "The ocean ate my global warming!"
Here are some links worth reading:
http://online.wsj.com/news/articles/SB10001424052702304636404577291352882984274
And, from a different rebuttal: "Referring to the 17 year ‘pause,’ the IPCC allows for two possibilities: that the sensitivity of the climate to increasing greenhouse gases is less than models project and that the heat added by increasing CO2 is ‘hiding’ in the deep ocean. Both possibilities contradict alarming claims."
Here's the entire piece from emeritus Alfred P. Sloan Professor of Meteorology, Department of Earth, Atmospheric and Planetary Sciences at MIT, Dr. Richard Lindzen: http://www.thegwpf.org/richard-lindzen-understanding-ipcc-climate-assessment/
And take your pick from all of the short pieces listed here: http://www.drroyspencer.com/2011/08/is-gores-missing-heat-really-hiding-in-the-deep-ocean/
And http://joannenova.com.au/2013/09/ipcc-in-denial-just-so-excuses-use-mystery-ocean-heat-to-hide-their-failure/
"Just where the heat is and how much there is seems to depend on who is doing the modeling. The U.S. National Oceanographic Data Center ARGO data shows a slight rise in global ocean heat content, while the British Met Office, presumably using the same data shows a slight decline in global ocean heat content."
http://www.arizonadailyindependent.com/2013/10/03/the-ocean-ate-my-global-warming-part-2/#sthash.idQttama.dpuf
Dr. Lindzen had this to say about the IPCC report: "I think that the latest IPCC report has truly sunk to a level of hilarious incoherence. They are proclaiming increased confidence in their models as the discrepancies between their models and observations increase."
http://www.arizonadailyindependent.com/2013/10/01/the-ocean-ate-my-global-warming-part-1/#sthash.oMO3oy6X.dpuf
So just as "believers" can ask "Why believe Heartland [financier for much of the NPCC], but not the IPCC," I can just as easily ask "Why should I believe you and not Richard Lindzen?"
"CCR-II cites more than 1,000 peer-reviewed scientific papers to show that the IPCC has ignored or misinterpreted much of the research that challenges the need for carbon dioxide controls."
And from the same author's series:
"Human carbon dioxide emissions are 3% to 5% of total carbon dioxide emissions into the atmosphere, and about 98% of all carbon dioxide emissions are reabsorbed through the carbon cycle.
http://www.eia.gov/oiaf/1605/archive/gg04rpt/pdf/tbl3.pdf
"Using data from the Department of Energy and the IPCC we can calculate the impact of our carbon dioxide emissions. The results of that calculation shows that if we stopped all U.S. emissions it could theoretically prevent a temperature rise of 0.003 C per year. If every country totally stopped human emissions, we might forestall 0.01 C of warming."
http://www.arizonadailyindependent.com/2013/08/01/climate-change-in-perspective/#sthash.Dboz3dC5.dpuf
Again, I have asked, repeatedly, where's the evidence of human impact on global warming? "Consensus" is not evidence. I ask for evidence and instead I get statements about the consensus that global warming happening. These are two different issues.
"Although Earth’s atmosphere does have a “greenhouse effect” and carbon dioxide does have a limited hypothetical capacity to warm the atmosphere, there is no physical evidence showing that human carbon dioxide emissions actually produce any significant warming."
Or Roger Pielke, Sr: http://wattsupwiththat.com/2011/09/20/pielke-sr-on-that-hide-and-seek-ocean-heat/
Or Lennart Bengtsoon (good interview): "Yes, the scientific report does this but, at least in my view, not critically enough. It does not bring up the large difference between observational results and model simulations. I have full respect for the scientific work behind the IPCC reports but I do not appreciate the need for consensus. It is important, and I will say essential, that society and the political community is also made aware of areas where consensus does not exist. To aim for a simplistic course of action in an area that is as complex and as incompletely understood as the climate system does not make sense at all in my opinion."
http://www.spiegel.de/international/world/meteorologist-lennart-bengtsson-joins-climate-skeptic-think-tank-a-968856.html
Bengtsson: "I have always been a skeptic and I believe this is what most scientists really are."
What Michael Crichton said about "consensus": "Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science, consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus."
Will Happer on the irrelevancy of more CO2 now: "The earth's climate really is strongly affected by the greenhouse effect, although the physics is not the same as that which makes real, glassed-in greenhouses work. Without greenhouse warming, the earth would be much too cold to sustain its current abundance of life. However, at least 90% of greenhouse warming is due to water vapor and clouds. Carbon dioxide is a bit player. There is little argument in the scientific community that a direct effect of doubling the CO2 concentration will be a small increase of the earth's temperature -- on the order of one degree. Additional increments of CO2 will cause relatively less direct warming because we already have so much CO2 in the atmosphere that it has blocked most of the infrared radiation that it can. It is like putting an additional ski hat on your head when you already have a nice warm one below it, but your are only wearing a windbreaker. To really get warmer, you need to add a warmer jacket. The IPCC thinks that this extra jacket is water vapor and clouds."
Ivar Giaever, not a climate scientist per se, but a notable scientist and also a skeptic challenging "consensus": http://www.telegraph.co.uk/earth/environment/climatechange/8786565/War-of-words-over-global-warming-as-Nobel-laureate-resigns-in-protest.html
Even prominent IPCC scientists are skeptics, even within the IPCC there is not agreement: http://www.climatedepot.com/2013/08/21/un-scientists-who-have-turned-on-unipcc-man-made-climate-fears-a-climate-depot-flashback-report/

I just saw that you can cut and past the automatic German transcript on the video info now, and maybe you even could before, it looks like it might be easier to correct this than to start from scratch? Actually you can get the gist of it from this, so maybe I was a bit hard on it earlier:

Bad ad hoc hypothese: he was imitating or lampooning a MIT professor everyone in the audience knows of.
This was not as funny as the audio track made it sound. I get humor. This was something else.
Last Week Tonight with John Oliver: Climate Change Debate
To be sure, it does not take "studies" and "experts" to "prove" that smog turns healthy breathable air into unhealthy unbreathable air.
But, again, the consensus among proponents of man-made global warming pretty much all agree that the cause is greenhouse gases. And the consensus is also that cattle accounts for the main source of greenhouse gases. I honestly don't see how anyone concerned with man-made global warming can ignore this and, therefore, not be vegetarian (i.e., be congruent in their behaviors and beliefs).
I recommend reading "Hot Talk, Cold Science", endorsed by respected physicist the late Frederick Seitz, William Harper professor of Physics at Princeton, Richard Lindzen, meteorologist at MIT, written by physicist Fred Singer.
If you want to know where Prof. Singer is coming from, read this (and skeptics are not "deniers"- that's just a slur).
But before you freak out, let me restate, it matters not; clean air is good either way; do things that contribute to clean air (like end the state -- > good luck with that!).
(Better to read and have these discussions with actual working climate scientists than to bother with Internet pundits either way.)
There is also "consensus" as to the three types of "deniers." If anyone calls me a "denier," I'd be curious as to which of the three types of "deniers" you think I belong to (as indicated in the Singer article linked above). And you can then give me your scientific explanations as to why my stance is not valid.
This is something worth keeping in mind (from Singer):
"I have concluded that we can accomplish very little with convinced warmistas and probably even less with true deniers. So we just make our measurements, perfect our theories, publish our work, and hope that in time the truth will out."
The warmistas matter as much as the deniers. And the bottomline remains: what are you going to do about it anyway? As has been shown over and over, your "votes" don't count for much (or anything at all). So, what are you going to do about this (other than fume and get your panties in a twist on videosift)? The same is true with the "deniers." And the skeptics (i.e., true scientists).
Science also doesn't work by consensus. No real scientist will say otherwise. You either prove/falsify some hypothesis or you don't. You don't determine the truth in science by "consensus." Scientific consensus, as has been said, is itself unscientific.
There is no "consensus" on the acceleration speed of falling objects. There is no "consensus" on whether the Earth is orbiting the sun. There is no "consensus" on water being made up of H2O. These you can measure and find out for yourself. (In fact, Galileo had less than 5% "consensus" on whether the Earth orbits the sun at the time of his experiments. Facts matter. "Consensus?" Not so much.)
But,
“If the science were as certain as climate activists pretend, then there would be precisely one climate model, and it would be in agreement with measured data. As it happens, climate modelers have constructed literally dozens of climate models. What they all have in common is a failure to represent reality, and a failure to agree with the other models. As the models have increasingly diverged from the data, the climate clique have nevertheless grown increasingly confident—from cocky in 2001 (66% certainty in IPCC’s Third Assessment Report) to downright arrogant in 2013 (95% certainty in the Fifth Assessment Report).”
Still, this does not in any way equate "denial" of man-made global warming or whatever other "climate change." That is simply an unfounded conflation made up by the propagandists which so many here take on as gospel.
And it still does not let anyone "off the hook" about actually doing something that matters if you care about it so much.
Let me know if anyone finds any "errors" in the science of the NGIPCC articles and studies that I posted above.
