CO2 Levels above 400 PPM Threshold for Third Month in a Row
Atmospheric concentrations of the greenhouse gas, which helps drive global warming, haven’t been this high in somewhere between 800,000 and 15 million years

April fell first. It lasted through May. Now June will be the third month in a row with average carbon dioxide levels above 400 parts per million.

CO2 Levels for February Eclipsed Prehistoric Highs
Global warming is headed back to the future as the CO2 level reaches a new high

More and more carbon dioxide molecules are accumulating in Earth's atmosphere.

February is one of the first months since before months had names to boast carbon dioxide concentrations at 400 parts per million.* Such CO2 concentrations in the atmosphere have likely not been seen since at least the end of the Oligocene 23 million years ago, an 11-million-year-long epoch of gradual climate cooling that most likely saw CO2 concentrations drop from more than 1,000 ppm. Those of us alive today breathe air never tasted by any of our ancestors in the entire Homo genus.
Homo sapiens sapiens—that’s us—has subsisted for at least 200,000 years on a planet that has oscillated between 170 and 280 ppm, according to records preserved in air bubbles trapped in ice. Now our species has burned enough fossil fuels and cut down enough trees to push CO2 to 400 ppm—and soon beyond. Concentrations rise by more than two ppm per year now.

I have read a lot about this subject, and when referring to "religion" i only point out that the fervor in which supporters attack deniers or even doubters is a parallel. Its a matter of close mindedness on both sides. I take a third stance that both are wrong and only time will tell. I like what both sides have to offer which is debate, which in most instances furthers the pursuit of knowledge.
Undoubtedly the eventual slinging of "Logic Flaws" comes to every discussion as a means to discredit or even silence the opposition, but can be applied to the logic of both sides.
Argument from ignorance (appeal to ignorance, argumentum ad ignorantiam) – assuming that a claim is true because it has not been or cannot be proven false, or vice versa
Argumentum ad hominem – the evasion of the actual topic by directing an attack at your opponent.
Burden of proof (see – onus probandi) – I need not prove my claim, you must prove it is false.
Circular cause and consequence – where the consequence of the phenomenon is claimed to be its root cause.
Fallacy of composition – assuming that something true of part of a whole must also be true of the whole
False dilemma (false dichotomy, fallacy of bifurcation, black-or-white fallacy) – two alternative statements are held to be the only possible options, when in reality there are more
Fallacy of the single cause (causal oversimplification[37]) – it is assumed that there is one, simple cause of an outcome when in reality it may have been caused by a number of only jointly sufficient causes.
All of these apply (and More) to both sides of the argument. I'm not saying the data is incorrect or even falsified, but even the slightest chance that is it misapplied or applied incorrectly has been questioned multiple times by multiple creditable sources. So I say again its a Theory and only time will reveal the true cause of Global Climate Change once ALL factors have been accounted for (which will take time as its deciding factor).

That is a cute trick you tried there, but flawed in so many ways. The 40% increase is significant, the fact is has been observed in such a short amount of time(50 years is a blink of eye as far as the Earth is concerned) is of great concern to this planet and our species.
Raising atmospheric concentrations of CO2 to 0.04 percent may not seem like much but it has been enough to raise the world's annual average temperature by a total of 0.8 degree Celsius [33.44 fahrenheit] so far

Fox News is not a credible news channel, so fat chance of getting people who know something about global climate change on it. Bill Nye or Al Gore would eat any opposition alive by simply reciting basic facts. Faux News is about as scientifically credible as Pat Robertson.

It truly is futile with you.
Now you are questioning the Moana Loa data based on a complete BS argument, that is is too close to a volcano for accurate numbers, when the reason why NOAA picked that location is because it is on an Island in the middle of the Ocean, a great spot for good data points, far removed from the pollution of big cities. Moana Loa does not spew CO2........
There are other locations that track CO2, unlike some of us, I do not get paid to post on here and do not have the time nor patience to do the research, provide good links, only for someone to just turn my links and research into a strawman debate full of logic fallacies.
The information and data regarding the CO2 concentration at 400ppm is there, there is NO debate that this is where the CO2 levels are. I do not care if you wish to ignore the data, ignorance is bliss for some. I do NOT appreciate it when you one tries to spread the ignorance, pull the wool over our eyes. It is obvious that you, Justoneman, and Semicollegiate are doing little to add to the discussion and a lot to disrupt the conversation.
Can any of you 3 provide good sources the 'debunks' the 400ppm CO2 levels we are currently observing?

The AIRS instrument measures 2,378 different infrared channels, or segments, of infrared light. Carbon dioxide absorbs and emits very specific wavelengths of infrared light, giving it a unique fingerprint. By measuring the emitted thermal infrared radiation, AIRS can detect this fingerprint, giving scientists a way to estimate carbon dioxide concentrations globally.
AIRS has shown that carbon dioxide is not evenly distributed over the globe; it is patchy with high concentrations in some places and lower concentrations in others. The gas’s transport and distribution through the atmosphere is controlled by the jet stream, by large weather systems, and by other large-scale atmospheric circulations. The findings from AIRS have raised new questions about how carbon dioxide is transported from one place to another—both horizontally and vertically—through the atmosphere. To address these questions and others, NASA is preparing to launch the Orbiting Carbon Observatory in 2014. It will be the first satellite dedicated to monitoring carbon dioxide, and it will do so with greater precision and detail than current instruments.

I think you meant to say "Data not conclusive" and I will continue with my previous train of thought on this. Is that your data, straight from the source, or has it been processed by Big Science for your digestion? The same talking points regurgitated over and over only follow the logic of "A lie repeated often enough tends to be mistaken for the truth".
Your Religion of Man Made Global warming may have tons of data behind it, but it has more rhetoric than a Sunday bible tent revival and is as close minded and hostile as the Klu Klu Klan when it come to acceptance of outside ideas and theories.
I still hold my ground in saying think for yourself, challenge each and every theory and never ever take someone else facts as gospel because a theory is an idea that needs to be challenged.
The atmosphere has a mass of about 5.15×1018 kg,[2] three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen,[1] 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.

What is your obsession with HFC's? They're terrible for the environment. They are a very detrimental part of the greenhouse effect. We still use them. What we used before HFC's were CFC's, those depleted the ozone, so we can't go back to those.

Actually, I was using satire.
Ok, I got HFC's mixed up with CFC's, and got that wrong.
But the principal of the satire is the same.
One day they tell us to stop using CFS's because it will cause an ice age.
The next day we have to stop using .... because it will cause global warming.
My satire was, if scientists are so concerned about global warming,
well they know how to cool the earth back down by doing
what was "causing" the global cooling.
It is the inane and contradictory back and forth that is absurd and that I was attempting to satirize.
In my opinion and from what we see in ice core samples and geological samples, the earth has, long before man arrived, gone through NATURAL extreme cooling periods and extreme warming periods. It is part of the natural life cycle of the earth, not caused by man.
Also, I want to make the point that it is not mandatory that one
must believe in global warming
to care about the environment.
One can care about clean water, air, etc. (the environment)
and not believe the contradictory "science" of global warming.
That is a line of propaganda that has been foisted upon people to make it appear that the two are inexorably linked, which they are not.

what amazes me is scientists have shown they can not be trusted through the years and make fun of those who don't trust them. the have basically lost public trust but instead of trying to earn the trust back they go the arrogant condescending jerk off route and tell everyone else they are stupid.
Nice PR campaign they have going LOL. when they start releasing technology for the sake of science instead of getting patents and selling technology to corporations the hide it away while lining their own pockets then I might listen to them a bit more. as it stands now i trust them as much as politicians and actors flying around first class or on private jets funded by taxpayers screaming the climate is changing.
people need to clean the trash out of there front yards before they worry about climate change. maybe start drinking out of glass bottles again. go back to making products that actually last and can be fix instead of everything being throw away. I would say all the trash is a bigger mounting problem than climate change. Funny how big trash cans are these days compared to 20 years ago.

I think we finally got to the meat of the matter, why so many armchair 'reseachers' vehemently deny man made climate change...........having to pay for it.
It doesn't get much more selfish than that.
