Global Warming Exists

Contention 1: CO2 increase from humans My opponent states that CO2 levels have never been this high, but that is incorrect. I give you the above graph measuring the past 600 million years of CO2 levels are we are actually at an all time low. Now the website I got this from no longer has this page up so I appologize. We can see from observance of this graph that we being at all time CO2 low levles that we are nowhere close to meeting the impact that my opponent brings up. We have been over 5,000 ppm of CO2 in our atmosphere and are now currently around apprx. 350 ppm CO2 levels. This chart above shows the CO2 and Earth's temperatures for the past 600 million years. My opponent's claims are incorect as we have had aburd levels of CO2 and temperature on Earth and may I ask how did we survive that? (. http://www.sustainableoregon.com...) My opponent tries to discard Dr. Spencer's evidence, because he doesn't appear to have a hypothesis, but that is not grounds to disqualify evidense as his findings were clear, so I extend them across the board. Contention 2: CO2 in atmosphere = increased temperatures. My opponent is under a great misconceptions as I acknowledge that CO2 traps heat, but I am simply arguing that Earth's temperature is not increasing, but is actually decreasing. To counter my opponent's first graph I'll reitterate my first graph of C2 in my last round. To see what my opponent does not show you is that the span between 0 AD- Present and you'll see an almost constant temperature. Humans have been on Earth for millions of years and the fact that it's nearly constant from a non-industrial era where there were no machines what-so-ever to present shows that there is no major change that my opponent change. My opponent question Dr. Eastbrock, but brings up no valid counterevidence other than Dr. Esper. Dr. Eastbrook naturally cools and ever since 2000 we have been in a cooling range. We have also seen how the IPP projections are incorrect. My opponent then tries to blatantly claim that Global Warming evidence that I have provided is skewed, but if that is true let's look at a graph from 1975 to 2010 it appears to have a positive slope, but let's back track a little back and make it a 1920-2005 graph since it would seem that it would only make the graph appear to have a steeper positive slope, right? Well that is where we are wrong. Here we see that the graph protrays a negative slope. (. http://blog.chron.com...) My opponent now brings up one theory relying on the Ozone hole and southern winds, but this is incorrect as the World Health Organization (WHO) has found that the Ozone is actually getting thicker and is expected to make a great recovery by 2025 due to the banning of Hydrocarbons. (. http://www.express.co.uk...) The graph above is raw satellite image data of the sea level rise over an 8 year period showing that there is little to no change in the Sea Levels rising. . http://joannenova.com.au...) (The sea level rises, on average, about 3 inches per century and it has been found to not even been rising at all. This graph is the sea levels off the cost of French Guyana which is one of the areas which is predicted to be flooded due to Global Warming, but as you can see by the graph (which goes to 2008) the sea level is currently on a downward trend. (. http://scienceandpublicpolicy.org...) The source is the PDF within the link. I have disproved both situations. Gore is one of the many who spread great awareness for Global Warming and he won the Nobel Peace Prize for it, but hen admitted that it's a scam to get money. That's a same.
