Global Warming is not significantly affected by human activity

Now, in debunking the opponent’s case, we have to observe one thing; accordingly to the Industrial Revolution/Co2 release correlation graph, we can see that the Co2 release has gone outside the main tenants of the normal Co2 equilibrium, which accordingly is around (when effected by negative feedback) 200ppmv. However, we humans now have a ppmv-Co2 rate of 380ppmv, henceforth this may be an offspring, but very unlikely, of huge negative feedback, or it may be the beginning of huge positive feedback in the creation of a new Venus-like Equilibrium. The opponent mentions the 100,000 years Ice Age Cycle phenomenon; henceforth, we are heading towards another “Ice Age” in the opponent’s view. Firstly, the world’s orbit-tilt, which causes the earth’s temperature to change (as well as volcanoes), are not acting as strong as they were during the last Ice Age. This means that the current Interglacial might be extended by 10,000 years. Apart from this, the plethora of Greenhouse Release, from Co2 and other gasses, outweigh the cooling capacity of the world. If they weren’t, then the world would have been experiencing a period of cool-down, perhaps a mini-Ice Age, from the 1950s. However, as seen, this has not been the case. [1] Apart from this, the opponent’s graph seems to show that in each 100,000 year Ice Age cycles; there has been a natural release of Co2 that has caused a gradual change in temperature. However, scientists know about how this change of temperature came about already. Interglacial epochs were characterized by the balance of Co2 concentration in the air and the Co2 sink in the ocean. There have been occasional times of massive Co2 release rise from volcanic eruptions known as large igneous provinces. These large igneous provinces have been known to cause a sudden change in temperature; however, there are no large igneous provinces that are active. Apart from this, one must observe the fact that today’s volcano does not emit as much Co2 as humans. In fact, accordingly to the USGS, annually humans generate 130 times more Co2 gas than volcanoes. The opponent is implying that there are natural causes for Co2 and other greenhouse gas release in the world; however, there is a plethora of evidence that suggests the contrary. This data has already been presented. Apart from this, correlation is not causation; because the current Co2 rates in the atmosphere correlates with those of ancient times (which it does not, as already stated), does not mean that this rapid release of Co2 has not been caused by humans. The opponent must observe; there is a difference between gradual change and sudden change. Gradual change implies that the change is made clear gradually. Sudden change is built upon the common knowledge that this change is sudden and unexpected. If this were to have been gradual change, then we humans would have knew about this much later; however, that is not the case. The opponent seems to argue that this change is normal for the earth; however, we must see that before 1750, Co2 was at a rate of 20ppm in the atmosphere; however, this Co2 rate rose rapidly from 1750, after the industrialization of human capital output capabilities. Now it is at 379ppm, an 18 times increase from the pre-1750 rate. Fossil fuel usage has released 7.2 gigaton of Co2 in 2000-2005. (gigaton-1 billion metric tons). One cannot simply argue that humans do not play a massive role; we are messing with the earth’s ability to absorb Co2 via deforestation, as well as adding 42% more Co2 into the earth’s atmosphere within the last 300 years. Humans have, in a significant manner, effected the overall global temperature. Citations: [1] . http://www.skepticalscience.com...
