Mankind Is the Main Cause of Global Warming

Contention 1: No Major/any CO2 Increase. Many Global Warming advocates state that CO2 levels are skyrocketing, 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. The above graph shows that comparisions of C13 (Carbon isotope) and this shows that there is little to no trend pertrade in many of these as the average is zero while the trend for all of these are zero. (http://www.drroyspencer.com...) This is important as the Carbon isotope is important in measuring this so called "Global Warming." 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...) Now I will move on to how Earth is actually cooling and how it's temperature is cooler than it has been. Contention 2: Earth is cooling. If we observe the above graph we can see that Earth has been a whole lot hotter than where we currently are to the point where the Earth's average temperature has been 7.5 degrees Celcuis hotter than it currently it is. You can also see that in the span of the past 10,000 years the temperature has leveld off, but you may ask yourself where does that place us in the lights of modern day? I am going to site Dr. Done Easterbrook, who is a climate scientist. Back in 2000 he predicted that Earth was entering a cooling phase. He predicts that for the next 20 years Earth will cool by 3/10 degree each year and that we are going to enter another little Ice Age like we did from 1650 and 1790. (http://www.cnsnews.com...) The funny thing is that many of my opponent's charts are actually from the incorrect IPPC. How about the "Hockey Stick" graph that many Global Warming supporters , including my opponent, argue about? Well if we observe the fallowing chart taken from Northern Scandenavia we can see that the Global trend over the past 1,000 years that the Global Cooling trend slope is that of -0.31 Degrees Celcuis, give or take 0.03 degrees (for the error room). Professor Dr. Jan Esper has found that the Earth's temperature of Earth actually decreases 0.3 per millenia due to the Earth moving away from the sun. (http://newsbusters.org...) Here is another graph from 1920 to 2005 and we can see that the graph has a negative temperature slope, thus meaning that the Earth is under a period of cooling. (http://blog.chron.com...) You can see in terms of more Warming in the evidence in which Scientists use Ice Cores Earth has actually been Cooling the past Mellenium. You can see that in terms of Gasses contribution to the Green House Effect the major contributer is Water Vapor and it's at 95% to CO2's 3.6% and this is the overall contribution including man made and natural. When we look to the chart on the left we can see that Man-Made CO2 does have a higher contribution to the atmosphere than Water Vapor, but that's because we do not create much water vapor as humans. Even with this evidence we can see that CO2 does not have any effect what-so-ever compared to Water Vapor. (http://www.geocraft.com...) Where might those CFCs be on this graph you may ask. Why it's under the Misc. gases section. Contention 3: Artic Ice. First, I would like to state that Pro's claim about the North Pole completely melting is bogus. Al Gore stated that the Artic Ice would be completely melted by 2014, but he is incorrect then and now. Jan. 6, 2012: The Coast Guard Cutter Healy breaks ice around the Russian-flagged tanker Renda 250 miles south of Nome. The Healy is the Coast Guard’s only currently operating polar icebreaker. The vessels are transiting through ice up to five-feet thick in this area. The 370-foot tanker Renda will have to go through more than 300 miles of sea ice to get to Nome, a city of about 3,500 people on the western Alaska coastline that did not get its last pre-winter fuel delivery because of a massive storm. (http://www.thegatewaypundit.com...) Let's go back to 2007-2008 and see if his claim was justified in the Artic Ice activity. Hmmm... It seems that he is incorrect, but let's look further into the near past. How about 2012-2013? (http://ginacobb.typepad.com...) We all remember the Climate Scientists that got stuck in Arctic Ice Earlier last year correct? Then a Russian Ice Breaker tried to free them, but got stuck. Can you guess what they were studying? They had predicted that all the Arctic Ice had melted due to Global Warming and that Earth would get flooded massively. Boy were they wrong. (http://www.nytimes.com...) ( http://www.americasfreedomfighters.com...) Dr. Koonin, former head of the Department of Energy under President Obama, has stated that the Global Warming scare is not suttle. This is because that he has found 3 things wrong and highly incorrect about the scare. 1. Shrinking of Artic Sea ice doesn't acount for the gaining of the Antartic ice. 2. The warming of Earth's temps today is the same as it was 30 years ago. 3. The sea levels rose at the same height and rate in the 20th cenury. (http://www.newsmax.com...) Contention 4: Sea Levels Here is another corralation that must happen. If the Ice Caps are completely melted as Pro claims then the sea level would have risen completely drowning tons of land. 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.

The source is the PDF within the link.Contention 5: The Weather My opponent is claiming that Hurricanes are increasing due to Global Warming, but this claim is indeed false! The hurricanes since the year 1900 to 2008 have actually been decreasing. The slope of this downward slope is .0016. Though it is small the hurricanes are still in a downward trend. As a matter of fact not only are Hurricanes on a downward trend, but they are at an all time low as in the year 2010, there was only 68 Hurricanes Globally, which is an all time low in the past 40 years. How about Tornados you may ask? In the graph above you can see that tornados are at an all time low in the past 60 years! (http://wattsupwiththat.com...) But what about Hurricanes? Here is a graph showing the number of days between hurricanes and this shows that the number of days between hurricanes is greatest at 76 days between hurricanes.The slope of this line is zero showing no trend of a massive storm increase. I'll pass it back to Pro now.
