Do you agree that we have seen a 40% increase in CO2 since the industrial revolution and human population explosion?
We as a species are destroying this planet.
For the record: never have i claimed to have a PHD, a cited Dr. Windsor a PHD who taught a atmospheric chemistry class in Florida Institute of Technology in 2003

These are real numbers. Within the last few hundred years, the very rightmost x value on this timescale , CO2 increase in the atmosphere has gone asymptotic. Can anyone really believe that there will be no ramifications to our climate from what you see here? If not, please explain why it is not important.

Underwater volcanoes heating Antarctic waters
Newly discovered volcanoes almost two miles tall
11 Jul 2011 - Scientists from the British Antarctic Survey (BAS) have discovered previously unknown volcanoes in the ocean waters around the remote South Sandwich Islands.
Sea-floor mapping technology reveals volcanoes beneath the sea surface
Using ship-borne sea-floor mapping technology during research cruises onboard the RRS James Clark Ross, the scientists found 12 volcanoes beneath the sea surface — some up to 3km (1.86 miles) high. They found 5km (3 mile) diameter craters left by collapsing volcanoes and 7 active volcanoes visible above the sea as a chain of islands.
According to a press release from the Proceedings of the National Academy of Sciences of the United States (PNAS), "this sub-sea landscape, with its waters warmed by volcanic activity creates a rich habitat for many species of wildlife and adds valuable new insight about life on earth." (Italics added)
The research is also important for understanding what happens when volcanoes erupt or collapse underwater and their potential for creating serious hazards such as tsunamis
Speaking at the International Symposium on Antarctic Earth Sciences in Edinburgh Dr Phil Leat from British Antarctic Survey said,
“There is so much that we don’t understand about volcanic activity beneath the sea — it’s likely that volcanoes are erupting or collapsing all the time. The technologies that scientists can now use from ships not only give us an opportunity to piece together the story of the evolution of our earth, but they also help shed new light on the development of natural events that pose hazards for people living in more populated regions on the planet.”

Magnetic Field Weakening in Stages, Old Ships' Logs Suggest
John Roach
for National Geographic News
May 11, 2006
Earth's magnetic field is weakening in staggered steps, a new analysis of centuries-old ships logs suggests.
The finding could help scientists better understand the way Earth's magnetic poles reverse.
The planet's magnetic field flips—north becomes south and vice versa—on average every 300,000 years. However, the actual time between reversals varies widely.
The field last flipped about 800,000 years ago, according to the geologic record.
Since 1840, when accurate measures of the intensity were first made, the field strength has declined by about 5 percent per century.

Abstract
A number of episodes of sharp geomagnetic field variations (in both intensity and direction), lasting on the order of a century, have been identified in archeomagnetic records from Western Eurasia and have been called "archeomagnetic jerks". These seem to correlate well with multi-decadal cooling episodes detected in the North Atlantic Ocean and Western Europe, suggesting a causal link between both phenomena. A possible mechanism could be a geomagnetic modulation of the cosmic ray flux that would control the nucleation rate of clouds. We wish to underline the remarkable coincidence between archeomagnetic jerks, cooling events in Western Europe and drought periods in tropical and sub-tropical regions of the northern hemisphere. The latter two can be interpreted in terms of global teleconnections among regional climates. It has been suggested that these climatic variations had caused major changes in the history of ancient civilizations, such as in Mesopotamia, which were critically dependent on water supply and particularly vulnerable to lower rainfall amounts. This is one of the foundations of "climate determinism". Our studies, which suggest a geomagnetic origin for at least some of the inferred climatic events, lead us to propose the idea of a geomagnetic determinism in the history of humanity.

Abstract
We report new archeointensity results from Iranian and Syrian archeological excavations dated from the second millennium BC.
These high-temperature magnetization data were obtained using a laboratory-built triaxial vibrating sample magnetometer.
Together with our previously published archeointensity results from Mesopotamia, we constructed a rather detailed geomagnetic field intensity variation curve for this region from 3000 BC to 0 BC. Four potential geomagnetic events (“archeomagnetic jerks”), marked by strong intensity increases, are observed and appear to be synchronous with cooling episodes in the North Atlantic.
This temporal coincidence strengthens the recent suggestion that the geomagnetic field influences climate change over multi-decadal time scales, possibly through the modulation of cosmic ray flux interacting with the atmosphere. Moreover, the cooling periods in the North Atlantic coincide with episodes of enhanced aridity in the Middle East, when abrupt societal changes occurred in the eastern Mediterranean and Mesopotamia.
Although the coincidences discussed in this paper must be considered with caution, they lead to the possibility that the geomagnetic field impacted the history of ancient civilizations through climatically driven environmental changes, triggering economic, social and political instability.

Observational arguments in favor of such a cloud are presented, and implications of the presence of a nearby cloud are discussed, including possible changes in terrestrial climate. It is suggested that the postulated interstellar cloud should encounter the solar system at some unspecified time in the near future and might have a drastic influence on terrestrial climate in the next 10,000 years.
ESA sees stardust storms heading for Solar System
PRESS RELEASE
Date Released: Monday, August 18, 2003
Source: Artemis Society
Until ten years ago, most astronomers did not believe stardust could enter our Solar System. Then ESA's Ulysses spaceprobe discovered minute stardust particles leaking through the Sun's magnetic shield, into the realm of Earth and the other planets. Now, the same spaceprobe has shown that a flood of dusty particles is heading our way.
...
What is surprising in this new Ulysses discovery is that the amount of stardust has continued to increase even after the solar activity calmed down and the magnetic field resumed its ordered shape in 2001.
Scientists believe that this is due to the way in which the polarity changed during solar maximum. Instead of reversing completely, flipping north to south, the Sun's magnetic poles have only rotated at halfway and are now more or less lying sideways along the Sun's equator. This weaker configuration of the magnetic shield is letting in two to three times more stardust than at the end of the 1990s. Moreover, this influx could increase by as much as ten times until the end of the current solar cycle in 2012.
Like a wounded Starship Enterprise, our solar system's natural shields are faltering, letting in a flood of cosmic rays. The sun's recent listlessness is resulting in record-high radiation levels that pose a hazard to both human and robotic space missions.
Galactic cosmic rays are speeding charged particles that include protons and heavier atomic nuclei. They come from outside the solar system, though their exact sources are still being debated.
Secular increase of the astronomical unit and perihelion precessions as tests of the Dvali–Gabadadze–Porrati multi-dimensional braneworld scenario

Abstract. An unexpected secular increase of the astronomical unit, the length scale of the Solar System, has recently been reported by three different research groups (Krasinsky and Brumberg, Pitjeva, Standish). The latest JPL measurements amount to 7 ± 2 m cy−1. At present, there are no explanations able to accommodate such an observed phenomenon, either in the realm of classical physics or in the usual four-dimensional framework of the Einsteinian general relativity. The Dvali–Gabadadze–Porrati braneworld scenario, which is a multi-dimensional model of gravity aimed at providing an explanation of the observed cosmic acceleration without dark energy, predicts, among other things, a perihelion secular shift, due to Lue and Starkman, of 5 × 10−4 arcsec cy−1 for all the planets of the Solar System. It yields a variation of about 6 m cy−1 for the Earth–Sun distance which is compatible with the observed rate of change for the astronomical unit. The recently measured corrections to the secular motions of the perihelia of the inner planets of the Solar System are in agreement with the predicted value of the Lue–Starkman effect for Mercury, Mars and, at a slightly worse level, the Earth.

Abstract
Several observations show unexplained phenomena in our solar system. These observations are e.g. the Pioneer Anomaly, an unexplained constant acceleration of the Pioneer 10 and 11 spacecraft, the Flyby Anomaly, an unexplained increase of the velocity of a series of spacecraft after Earth gravity assists, the recently reported increase of the Astronomical Unit defined by the distance of the planets from the Sun by approximately 10 m per century, the quadrupole and octupole anomaly which describes the correlation of the low l contributions of the Cosmic Microwave Background to the orientation of the Solar system. Lacking any explanation until now, these phenomena are still investigated intensively. In my talk I will discuss the present status of those investigations and the attempts to find reasonable explantions.
6 The increase of the Astronomical Unit
6.1 The observation
From the analysis of radiometric measurements of distances between the Earth and the major planets including observations from Martian orbiters and landers from 1961 to 2003 a secular increase of the Astronomical Unit of approximately 10 m/cy has been reported (36) (see also the article (37) and the discussion therein).
...
Cosmic expansion The influence of cosmic expansion by many orders of magnitude too small, see Sec.9.2. Neither the modification of the gravitational field of the Sun nor the drag of the planetary orbits due to the expansion is big enough to explain this drift.
...
The reason for this is totally unclear. One may speculate that an unknown gravitational field within the Solar system slightly redirects the incoming cosmic microwave radiation (in the similar way as a motion with a certain velocity with respect to the rest frame of the cosmological background redirects the cosmic background radiation and leads to modifications of the dipole and quadrupole parts). Such a redirection should be more pronounced for low–l components of the radiation. It should be possible to calculate the gravitational field needed for such a redirection and then to compare that with the observational data of the Solar system and the other observed anomalies.
...
8.2 Other anomalies?
There is one further observation which status is rather unclear bit which perhaps may fit into the other observations. This is the observation of the return time of comets: Comets usually come back a few days before they are expected when applying ordinary equations of motion. The delay usually is assigned to the outgassing of these objects. In fact, the delay is used for an estimate of the strength of this outgassing. On the other hand, it has been calculated in (44) that the assumption that starting with 20 AU there is an additional acceleration of the order of the Pioneer anomaly also leads to the effect that comets come back a few days earlier. It is not clear whether this is a serious indications but a further study of the trajectories of comets certainly is worthwhile.
Ribbon at Edge of Our Solar System: Will the Sun Enter a Million-Degree Cloud of Interstellar Gas?
ScienceDaily (May 24, 2010) — Is the Sun going to enter a million-degree galactic cloud of interstellar gas soon?
Scientists from the Space Research Centre of the Polish Academy of Sciences, Los Alamos National Laboratory, Southwest Research Institute, and Boston University suggest that the ribbon of enhanced emissions of energetic neutral atoms, discovered last year by the NASA Small Explorer satellite IBEX, could be explained by a geometric effect coming up because of the approach of the Sun to the boundary between the Local Cloud of interstellar gas and another cloud of a very hot gas called the Local Bubble. If this hypothesis is correct, IBEX is catching matter from a hot neighboring interstellar cloud, which the Sun might enter in a hundred years.
...
[atsimg]http://files.abovetopsecret.com/images/member/63ffeeb144dd.jpg[/atsimg]
The Sun traveling through the Galaxy happens to cross at the present time a blob of gas about ten light-years across, with a temperature of 6-7 thousand degrees kelvin. This so-called Local Interstellar Cloud is immersed in a much larger expanse of a million-degree hot gas, named the Local Bubble. The energetic neutral atoms (ENA) are generated by charge exchange at the interface between the two gaseous media. ENA can be observed provided the Sun is close enough to the interface. The apparent Ribbon of ENA discovered by the IBEX satellite can be explained by a geometric effect: one observes many more ENA by looking along a line-of-sight almost tangent to the interface than by looking in the perpendicular direction.

Our solar system may be headed for an encounter with a dense cloud of interstellar matter
Our solar system may be headed for an encounter with a dense cloud of interstellar matter–gas and dust–that could have substantial implications for our solar systems interplanetary environment, according to University of Chicago astrophysicist Priscilla Frisch. The good news is that it probably won’t happen for 50,000 years. Frisch presented the results of her research Monday, June 10, at the meeting of the American Astronomical Society in Madison, Wisc.
Frisch has been investigating the interstellar gas in the local neighborhood of our solar system, which is called the Local Interstellar Medium (LISM). This interstellar gas is within 100 light years of the Sun. The Sun has a trajectory through space, and for most of the last five million years, said Frisch, it has been moving through a region of space between the spiral arms of the Milky Way galaxy that is almost devoid of matter. Only recently, within the last few thousand years, she estimates, the Sun has been traveling through a relatively low-density interstellar cloud.
“This cloud, although low density on average, has a tremendous amount of structure to it,” Frisch said. “And it is not inconsistent with our data that the Sun may eventually encounter a portion of the cloud that is a million times denser than what we’re in now.”
Frisch believes the interstellar cloud through which we’re traveling is a relatively narrow band of dust and gas that lies in a superbubble shell expanding outward from an active star-formation region called the Scorpius-Centaurus Association. “When this superbubble expanded around these stars, it expanded much farther into the region of our galaxy between the spiral arms, where our sun lies, because the density is very low,” Frisch said. “It didn’t expand very far in the direction parallel to the spiral arms because it ran into very dense molecular clouds.”

There is no such thing as "imbalance" with regards to atmospheric CO2. The Earth has gone through periods when atmospheric CO2 levels were 4,000 ppm and higher yet the Earth recovered.
What proof do you have that an increase of 100ppm-120ppm or even 500ppm of atmospheric CO2 is catastrophic?... Computer models which have been shown time and again not to account for natural factors that affect climate change?...

In fact, as I have pointed out before with other research, the Earth has been warmer than during the 20th, or the beginning of the 21st century, yet CO2 levels in the atmosphere were much lower than now.
Such dramatic Climate Changes occurred globally, not just in one area, or just in the northern hemisphere.
...
More abrupt climate changes have occurred in the past.
The claim that the warming of the 20th century is "unprecedented" is nothing but a lie.
Global borehole temperature changes have shown that as areas of the world were still undergoing the LIA (Little Ice Age) the Earth was warming and continued to exponentially warm since the early 1600s.
...
That's without mentioning the fact that people like you continue to ignore the real fact that during warming periods, as the atmosphere warms water vapor levels increase naturally.
The sign of the correlation between the AM and temperature switches around 1960, suggesting that anthropogenic forcing superseded natural forcing as the major driver of AM changes in the late 20th century.

You didn't answer any of the questions that I asked directly to you...you call me a liar instead of answering the questions.
I have more integrity than to get down to insults with you. But, don't dare accuse me of lying, I know exactly what I wrote and the context I wrote it in... This:
As Ray already pointed out, the percentage of the carbon isotope that represents human emissions is not 40%, so a large part of the increase is from natural sources too.
Was in reference to the 40% increase in CO2 that JRod kept referring to, which Ray pointed out is NOT all 100% human emissions. I was pointing out that part of that 40% was natural emissions as well, and was not purely anthropogenic.
I question your integrity since you flat out accuse me of lying about something that you didn't bother to read and do your homework on. Here was the original comment from raymunduko:
You mean 60 ppm? And I already gave you those articles...
According to the isotopes the other 60 is natural.

Amazing double-standard. Of course the past is relevant to today's understanding, what kind of scientist are you? You aren't applying the same standard of "conditions were far different" a few hundred thousand years ago to your data when it is convenient for you.
...
So it was so different in pre-historic times, but NOT so vastly different in the ice cores over the last 800K years that you don't ignore that data? Only the last 800K years of findings apply, right? And not the GEOCARB data or stomata records or anything else?
What a joke. You can use data from sources that are from hundreds of thousands of years ago to support your arguments, but ignore the data conveniently when it doesn't match your mental model.

You would know if your paper was printed, but you aren't sure? LOL Impressive. Must be a really big journal. One that I shouldn't be concerned with, because they are a small journal that nobody has ever heard of?

Again, double-standards. You can call someone else's journal crap, the same standard can be applied to your work and anything you say.
You don't see the hypocrisy in your comment, that you expect that your paper should be taken seriously because it was peer-reviewed and possibly published, even though we don't know what publication.... yet you scold Beck's work because it's in a journal that YOU think is crap? Geez.
And you are going to bust my chops over a claim I made from something I heard first hand? You discredit everything else he understands about CO2 and the physics of it, simply because I made an off-hand comment?

You injected yourself into the thread, made a bunch of claims, tried to poke holes in mine and others. When I call you out on them, you avoid them. That's is why you should address them, and they were directed to you as direct questions.
Questions such as:
Q1
Q2
Q3
I would re-phrase the above question to say - can you show me anything, in papers or otherwise, that shows that these factors are accounted for in the same models that predict our doom? If they aren't, and we know they have an impact on CO2, please show how the models aren't wrong and we're all supposed to believe that human emitted CO2 is the cause of current warming and not something else?

And instead, said it is "irrelevant". It is most certainly relevant.

Last but not least, the one question I will ask, is why does temperature increase before CO2 does?
...
Rather than argue the science and the work of the papers that have been published, you are trying to find a reason to discredit me personally and attack me by calling me a liar for something that was clearly a misunderstanding on your part.
I look forward to open discussions and discourse, but not with people the likes of you. You are dishonest. Each of the posts I've written to you, you have done nothing more than try to attack my character, the character and integrity of my references instead of the work that is published.
You should be ashamed to call yourself a scientist, if you do. You are clearly a proponent of AGW and not someone who is open to finding truth, just following the truth others lay at your feet.
Natural CO2 emissions account for about 96% of annual CO2 emissions. There is no surprise from me that the Amazon or other large carbon-dense areas are emitting a much higher amount of CO2 than humans - it's simple math. Before we started pumping CO2 into the atmosphere, it was was essentially 100%. As I recall, global carbon sink capacity is about 101% of natural emissions. Thus the imbalance, since global CO2 emissions are now at 104.17% or so of natural emissions. There's simply not enough being taken out of the atmosphere annually, and so even the small amount that we contribute adds up.
Those are roughly IPCC estimates, so you'll have to take it up with them if you disagree. This is another source of information on the subject; one concern is that the sinks themselves might start contributing to CO2 emissions. Already, I've spent a great deal of time posting today, and competition for my time is immense, so further examination of this will have to wait.
I will not defend the models and have no reason to do so.

How is there not an imbalance? We are emitting enough CO2 that the global CO2 concentration is increasing. Prior to the industrial age, it was roughly the same or slightly declining. Were humans around when CO2 levels were at 4000 ppm?
I don't see why I should offer any proof of that at all. I didn't claim it was catastrophic; the IPCC might, but they can defend themselves. I wrote that one shouldn't assume cold is bad or hot is good.
It is very amusing that you claim to have integrity to not insult someone, then immediately insult someone in the same post. You for some irrelevant reason asked if I had a peer reviewed paper. I responded that I did. You mocked me for not knowing whether or not it was published yet. Rather ironic. For your information, there have been some issues with the journal; it was supposed to be published back in April, but it keeps getting pushed back. I'm not keeping tabs on it; it is a paper I wrote over an experiment I conducted several years ago, in a field I do not work in currently, done when I was still in college. I don't mean to brag, but getting a paper into a journal as an undergraduate is no small feat. But if you want to proceed to mock and demean, you might as well throw up your publications so that we can judge you, as you have me.
If I had no upcoming journal publication, what would you then have written - that I have no room to criticize because I had no paper past peer review? Do you also tell people not to critique movies unless they make their own?
That's rather harsh, I must be so mistrusted. My sources for that chart:

On November 17, 2003 National Oceanic and Atmospheric Administration reported that the concentration of the potent greenhouse gas methane in the atmosphere was leveling off and it appears to have remained at this 1999 level (Figure 1). The Intergovernmental Panel on Climate Change in 2007 acknowledged that methane concentrations have plateaued, with emissions being equivalent to removals. These changes in methane atmospheric dynamics have raised questions about the relative importance of ruminant livestock in global methane accounting and the value of pursuing means of further suppressing methane production from ruminants. At this time there is no relationship between increasing ruminant numbers and changes in atmospheric methane concentrations changes, a break from previously assumed role of ruminants in greenhouse gases (Figure 1).
...
Despite this lack of success in reducing ruminant methane production, since 1999, the link between atmospheric methane and ruminant population growth seems to have broken down. This has occurred despite accelerated increases in ruminant numbers without an equivalent increase on global methane concentrations within the current time frame.
