Global warming

I would like to thank my opponent for continuing into the second round of this debate, and I accept his definition of global warming. I would like to point out that my opponent has not prove any piece of his argument,nor has he provided any sources. For these reasons, again, I strongly urge you to vote in affirmation of the resolution. Now I will present an overview, of my points then negate my opponents. Whether we choose to take action or not is a different story, but once I prove to you that global warming is real, I promise you will think twice about selecting "con" in the BIG ISSUES spot for your profile on debate.org. Now when it comes down to it, the whole debate is centered around proof. Well I know that I am not a scientist, nor my partner. So as the Pro side of this resolution I would like to provide you with a source that shows, "scientists" agree that global warming is real. (http://www.cnn.com...) My contentions, 1. Glaciers have melted and retreated dramatically, proof that global warming is real 'Around the world these massive moving fields of ice have been posting record losses. The World Glacier Monitoring Service, based at the University of Zurich in Switzerland, looked at nearly 30 reference glaciers in nine different mountain ranges across the globe. In March, its scientists reported disturbing news. The average melting and thinning rate of those glaciers has more than doubled between the 2004 and 2006. "The latest figures are part of what appears to be an accelerating trend with no apparent end in sight," said Wilfried Haeberli, who directs the glacier-monitoring group. In Antarctica, a large chunk of the Wilkins Ice Shelf recently collapsed into the sea. Satellite images show the Wilkins Shelf began falling apart in late February, when a large iceberg 41 kilometers by 2.5 kilometers (25.5 miles by 1.5 miles) broke away from the shelf. This triggered a runaway disintegration of an additional 405 square kilometers (160 square miles) of the shelf. The total loss was 8.5 times the area covered by New York's Manhattan island. As of March 23, only a 6 km (3.7 mile) wide strip of intact ice was protecting the shelf from further collapse. Scientists from the U.S. National Snow and Ice Data Center and the British Antarctic Survey put the blame for the Wilkins' massive melt-triggered event on a warmer world. "We believe the Wilkins [Shelf] has been in place for at least a few hundred years," said Ted Scambos, a lead scientist with the snow and ice data center. "But warm air and exposure to ocean waves are causing a break-up." With strong evidence that ice is melting globally atop mountains and at Earth's poles, scientists say that it's pretty clear our planet is warming. And that could spell big changes even in regions where the only ice you'd normally encounter is in a beverage.' Refuting Mr. Cotton Ball's arguments, "1.)First of all the world we live on is billions of years old and in this time period the earth has went threw many cooling and heating periods this is a fact currently we are coming off the last ice age and the world is gradualy heating back up." 'This is not new news. These changes started 18,000 years ago, as the earth emerged from the Pleistocene Ice Age-- a time when ice-covered mammoths and mastodons roamed the earth. Geologists know great ice sheets once covered large portions of the continents. These glaciers have alternately retreated and advanced as the earth has warmed and cooled, in cycles spanning hundreds, thousands, and millions of years. Historical data from ocean sediments and ice cores indicate warm interglacial periods of 15,000 - 20,000 years separate each major ice age. We currently are in an interglacial period, and are due for the next 100,000- year Ice Age.' "2.) My next point is a point i have come up with my self and supports my first point. it is largley accepted that the resone dinosours grew so large is because a slitly more heated earth than we know now, and a excess of oxegen and carbon manoxide. over the last 400 years literly not even a second in Geological time the average height of human beings has grown a foot and a half. this is likely do to the increase in carbon monoxide and oxeygen in our ozone layer." I do not agree with this, because their is no proof. Making the ground to debate this point, hard. Sources: (http://www.millenniumassessment.org...) (http://climate.weather.com...)
