Human induced global warming exists

Thanks to my opponent for his response. 1) "His long-term graph does show that there have been instances in history warmer than today. He argues that that does not mean human induced global warming does not exist. However, if you look at his wonderful graph, you will see that the period of time between each "hike" in temperature is about the same. Furthermore, the increase in temperature has been steeper before." This proves and disproves nothing. Con has yet to prove that this disproves human induced global warming, which he should do as there is a shared BOP. 2)"I don't know where your link to NASA goes, but it is not NASA explaining that global warming exists, it leads to a page called What NASA does?" That was to prove that NASA was a space organization and not an environmentalist company. The link after that is a link to the chart at http://data.giss.nasa.gov... . The chart does prove that temperatures are increasing. Solar Flares In 2008, the solar cycle is at the deepest minimum in nearly a century. [2] However, if you look at the chart in [3], there was no significant drop anywhere after 2000. This proves that solar flares have no significant effect on climate. NOAA also agrees that solar flares do not do much warming to the Earth. "Although solar flares, and associated coronal mass ejections, can bombard Earth"s outermost atmosphere with tremendous amounts of energy, most of that energy is reflected back into space by the Earth"s magnetic field. Because the energy does not reach our planet"s surface, it has no measurable influence on surface temperature. A small fraction of the extra heat from the solar flare radiates to layers of the atmosphere below the thermosphere, but it is miniscule compared to the normal amount of heating the lower layers of the atmosphere already experience from incoming visible and ultraviolet sunlight. Short-lived solar explosions don"t influence weather events like the March 2012 heat wave, but longer-term variations in solar output might affect Earth"s climate."[1] My analogy explained P1. There were times that were warmer than now. P2. Temperatures have risen lately, with a high correlation to CO2. [4] C. Because there were times that were warmer than now, the temperature rise is not due to CO2. The above logic is flawed, which is the logic my opponent's quote at 1) is based on. Correlation and Causation CO2 does not just correlate to temperatures, it also does cause global warming. "Carbon dioxide is a greenhouse gas as it transmits visible light but absorbs strongly in the infrared and near-infrared, before slowly re-emitting the infrared at the same wavelength as what was absorbed."[5] Greenhouse gases cause the greenhouse effect[6], which causes global warming.[7] I also have proven that humans emit lot's of CO2 in round 1. In conclusion, CO2 is emitted by humans, causes global warming and correlates with temperatures. I await my opponent's response. [1]http://www.climatewatch.noaa.gov... [2]http://science.nasa.gov...
