Or, you could just look up what he actually wrote instead of speculating - Svante Arrhenius (1906):

That was over a hundred years ago. The IPCC last estimated doubling the CO2 concentration to cause a 1.5C to 4.5C increase in temperature. NASA says the Earth's temperature rose between 0.6C and 0.9C from 1906 to the present. The CO2 concentration has risen by about 1/4th, from ~300ppm to ~400ppm. How wrong was he, precisely?

It's an illustration of the simple scientific fact that even a minute quantity of a substance can have an effect on an environment, which you mocked with your gigantic images. Botox is not simply a cosmetic treatment - it's an extremely potent toxin.

I think I've gone over this before. Why don't you define "now" and "much higher" for us, so that we can have a clearer understanding of your argument? Since skeptic websites frequently cite this, I'm sure it won't be much trouble.

Abstract
Lake-based paleotemperature reconstructions are of particular importance in the Arctic, where other useful archives (e.g., tree rings, speleothems) for developing dense networks of quantitative climate records are absent or limited.
...
The previously published mass accumulation rate from Lower Murray Lake has been interpreted as a paleotemperature record and provides complimentary information to the new alkenone record. Melt percentage measurements from the nearby Agassiz Ice Cap provide another independent summer temperature reconstruction for comparison. Most strikingly, the alkenone record reveals warm lake water temperatures beginning ~800 AD and persisting until ~1200 AD, with temperatures up to 2-3 deg C warmer than the mean temperature for the past 100 years. This dramatic medieval warm period on Ellesmere Island interrupted a distinct (neoglacial) cooling trend that had begun approximately 2000 years earlier. Furthermore, the three warmest intervals seen in the alkenone record during the past 5,000 years correspond to the periods during which the area was occupied by Paleo-Eskimo groups, providing evidence that local climate conditions played a significant role in determining migration patterns of people of the Arctic Small Tools tradition.

Now that you recognize this, you can abandon the talking point that an increase in CO2 has no effect because the concentration is so low, which is what you were implying with the pictures before.

I can only speculate as to why there hasn’t been a prosecution. But it’s worth noting that the Pine Tree project is owned by the Los Angeles Department of Water and Power. Prosecuting such a high-profile governmental entity for repeatedly violating some of America’s oldest wildlife-protection laws would be politically embarrassing. On its website, the LADWP claims that the Pine Tree facility is the “largest municipally owned wind farm in the US.” The agency also says the Pine Tree project “displaces at least 200,000 tons of greenhouse gases” per year.xv
In March 2013, a peer-reviewed study published in the Wildlife Society Bulletin, estimated that in 2012 alone, US wind turbines killed 888,000 bats and 573,000 birds. Those bird kills included 83,000 raptors.xvi In September 2013, some of the Fish and Wildlife Service’s top raptor biologists reported that the number of eagles being killed by wind turbines has increased dramatically over the last few years, going from two in 2007 to 24 in 2011. In all, the biologists found that wind turbines have killed some 85 eagles since 1997. And Joel Pagel, the lead author of the report, told me that that the eagle-kill figures they used are “an absolute minimum.” Among the carcasses: six bald eagles.
Pagel’s study was published just five months after the Fish and Wildlife Service issued a report which said flatly “there are no conservation measures that have been scientifically shown to reduce eagle disturbance and blade-strike mortality at wind projects.” xvii
The Pagel study is key because it shows that as more wind projects have been built, more birds have been killed. In 2007, the US had about 17,000 megawatts of installed capacity. By 2011, that figure had nearly tripled to about 47,000 megawatts.xviii Over that time period, the number of documented eagle kills increased by a factor of 12.

When SSTs are anomalously cool in the interior North Pacific and warm along the Pacific Coast, and when sea level pressures are below average over the North Pacific, the PDO has a positive value. When the climate anomaly patterns are reversed, with warm SST anomalies in the interior and cool SST anomalies along the North American coast, or above average sea level pressures over the North Pacific, the PDO has a negative value.

That's what was thought, but in fact we know now that heat has been escaping the Earth's atmosphere at much higher levels than were previously thought possible.
show us where CO2 didn't cause warming while other factors were not involved
The model has no realistic ocean, no El Niño, and no hydrological cycle, and it was tuned to give the result it gave.

He was VERY wrong about a lot of things. First the absorption of infrared radiation by CO2 does not double with a doubling of CO2 levels...
...
Wrong analogy... CO2 is not a toxic substance at the levels it exists on Earth's atmosphere. Botox in itself is a very toxic substance...
...
The Medieval Warming Period had global temperatures up to 1-3C the levels of the late 20th century and the beginning of the 21st century. Not even today on 2014 are temperatures higher than they were in the Medieval Warm Period. A period in which CO2 levels were LOWER than now...
...
Again, who is to forget the graph and research that showed a COOLING trend in overall temperatures from 2000 to the present in the northern hemisphere.

BTW Greven, and the rest of the AGW religious followers out there....
You're quite ignorant of how electrical grids work and greatly misunderstand what's being done in this situation.
I certainly could be wrong in this instance, since I don't know the full situation.
I still fail to see how this derail has anything to do with climate change.
In addition, I know quite well how the grids work and generating stations, because I am an engineer and I designed critical systems in both nuclear and thermal generating stations.
You'll probably gloss over it, just like SonOfTheLawOfOne did earlier when shown how wrong he was. Maybe with a series of random quotes and charts again, even!
The reason they look much different is because I was plotting average annual temperatures, rather than monthly temperatures.
base my opinion on AGW on scientific findings. Not models, not theories, but what's been recorded as happening and known mechanics.

Look Greven… if you’re going to call someone out, you better be ready to lay all of your cards on the table. You already tried this once before in this thread, by falsely accusing me of something I didn’t say, because you didn’t read the rest of the posts in the thread. You were flat out, WRONG, for doing so. You were convinced that I was lying until I shoved the proof in your face by pointing you to Raymunduko’s prior post, and you hardly admitted you were wrong.
You also did something similar with bobs_uruncle by first insulting him, when he CLEARLY has a far superior background to yours in that area:
...
And then turned around after you got owned by his response and said:
...
I think the same applies to the rest of the thread. And even after that, you continue to try to cover up your arrogance in a follow-up post with this:
...
You presented a graph that was an inaccurate representation of the data. I showed you where you were wrong because you were using the wrong data from GISS. You have the cajones to say something like this:
...
Even though when you were shown that your own graph was incorrect because of a simple mistake in your source data, you admitted that I was correct:
...
And then you tried to cover it by pointing out stupid axis shift tricks in the graph that anyone could do, to try and show how the data can be manipulated, which ironically illustrated most of my arguments about bad data.
...
That alone, shows how ridiculous your statement is since your sources from SkepticalScience LOVE to use the IPCC and all of those wonderful models and theories that you pretend not to use. In my next post, I'll make sure to highlight how little you use the models and theories.

Clearly, by looking above, the science is not settled. There is still far too much dispute over just the role the sun plays, and too much that is not understood about our climate and natural CO2 sinks, of which we have no way to accurately measure their capacity or their rate of emission. To say otherwise, is foolish and asinine, and I would laugh at any “proof” claiming to be accurate. So would any climate scientist. Few would argue that CO2 sinks are poorly measured.
The AGW theory is not sound, and it has been shown unequivocally that CO2 rises as a RESULT of temperature

I will NOT however, let you diminish my character any further in a post to myself

The AGW theory is not sound, and it has been shown unequivocally that CO2 rises as a RESULT of temperature - ie. Cause and Effect, which governs the entire universe. For AGW to be true, either the theory is wrong and there are only rare cases of CO2 preceding temperature for some other reason besides man (because we weren't around when it happened), or cause and effect are wrong and all of science will be turned upside down by AGW.

Please learn what the term temperature anomaly means and how it is calculated. (Hint, it is not the same as absolute temperatures). After having done so, revisit that idiotic blog. 2012 was the hottest year in North America on record.
You see, understanding the terms helps go a long way in understanding the science. The same applies to what the term heat wave index actually means. Yes, the heat waves of the 1930's have not been matched. But that's weather, not climate.
The myth:
CO2 is plant food
Earth's current atmospheric CO2 concentration is almost 390 parts per million (ppm). Adding another 300 ppm of CO2 to the air has been shown by literally thousands of experiments to greatly increase the growth or biomass production of nearly all plants. This growth stimulation occurs because CO2 is one of the two raw materials (the other being water) that are required for photosynthesis. Hence, CO2 is actually the "food" that sustains essentially all plants on the face of the earth, as well as those in the sea. And the more CO2 they "eat" (absorb from the air or water), the bigger and better they grow.
The reality:
An argument made by those who prefer to see a bright side to climate change is that carbon dioxide (CO2) being released by the burning of fossil fuels is actually good for the environment. This conjecture is based on simple and appealing logic: if plants need CO2 for their growth, then more of it should be better. We should expect our crops to become more abundant and our flowers to grow taller and bloom brighter.
However, this "more is better" philosophy is not the way things work in the real world. There is an old saying, "Too much of a good thing can be a bad thing." For example, if a doctor tells you to take one pill of a certain medicine, it does not follow that taking four is likely to heal you four times faster or make you four times better. It's more likely to make you sick.
It is possible to boost growth of some plants with extra CO2, under controlled conditions inside of greenhouses. Based on this, 'skeptics' make their claims of benefical botanical effects in the world at large. Such claims fail to take into account that increasing the availability of one substance that plants need requires other supply changes for benefits to accrue. It also fails to take into account that a warmer earth will see an increase in deserts and other arid lands, reducing the area available for crops.
Plants cannot live on CO2 alone; a complete plant metabolism depends on a number of elements. It is a simple task to increase water and fertilizer and protect against insects in an enclosed greenhouse but what about doing it in the open air, throughout the entire Earth? Just as increasing the amount of starch alone in a person's diet won't lead to a more robust and healthier person, for plants additional CO2 by itself cannot make up for deficiencies of other compounds and elements.
What would be the effects of an increase of CO2 on agriculture and plant growth in general?
1. CO2 enhanced plants will need extra water both to maintain their larger growth as well as to compensate for greater moisture evaporation as the heat increases. Where will it come from? In many places rainwater is not sufficient for current agriculture and the aquifers they rely on are running dry throughout the Earth (1, 2).
On the other hand, as predicted by climate research, we are experiencing more intense storms with increased rainfall rates throughout much of the world. One would think that this should be good for agriculture. Unfortunately when rain falls in short, intense bursts it does not have time to soak into the ground. Instead, it quickly floods into creeks, then rivers, and finally out into the ocean, often carrying away large amounts of soil and fertilizer.
2. Unlike Nature, our way of agriculture does not self-fertilize by recycling all dead plants, animals and their waste. Instead we have to constantly add artificial fertilizers produced by energy-intensive processes mostly fed by hydrocarbons, particularly from natural gas which will eventually be depleted. Increasing the need for such fertilizer competes for supplies of natural gas and oil, creating competition between other needs and the manufacture of fertilizer. This ultimately drives up the price of food.
3. Too high a concentration of CO2 causes a reduction of photosynthesis in certain of plants. There is also evidence from the past of major damage to a wide variety of plants species from a sudden rise in CO2 (See illustrations below). Higher concentrations of CO2 also reduce the nutritional quality of some staples, such as wheat.
4. As is confirmed by long-term experiments, plants with exhorbitant supplies of CO2 run up against limited availability of other nutrients. These long term projects show that while some plants exhibit a brief and promising burst of growth upon initial exposure to C02, effects such as the "nitrogen plateau" soon truncate this benefit
5. Plants raised with enhanced CO2 supplies and strictly isolated from insects behave differently than if the same approach is tried in an otherwise natural setting. For example, when the growth of soybeans is boosted out in the open this creates changes in plant chemistry that makes these specimens more vulnerable to insects, as the illustration below shows.

I think your response was well thought out and written but you fail to take into consideration the technology of the time.
People hypothesize based off the current data and the instruments available at the time to interpret that data. That has been the history of science ever since the church got out of the way.
My point is very simple and not overly complex. New instruments are constantly developed, and those instruments allow us to interpret data differently. The fact hat so many are working on new instruments right now to prove global warming correct makes be believe they will eventually prove it wrong.
Climate Change is an undeniable fact, but human induced Climate Change ultimately is a theory, and most theories are proven wrong. Those theories are constantly adjusted until one day something completely breaks everything we understand.
Those anomalies make be believe that no matter how much science believes it understands, we are still at minimum 200 or more years from even understanding physics. If we don't even have a full grasp of physics, then it is safe to say we don't understand the workings of our planet, and the entire climate model.
So how about the Theory of Blank Slate that was proven wrong?
Or phrenology
How about Einstein's Static Universe?
Cold Fusion?
Or this entire list of superseded scientific theories that were once accepted by science?

You are citing prehistoric CO2 levels, way before man walked the Earth. That is misleading, it is as if you are trying to compare apples to oranges.
