First can i state that this is going to be a debte which should be fun for both sides
Global warming as a whole(natural and man made)
The proof that global warming is real is right in front of our eyes the average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.
Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss.
Man made global warming
Industrialization, deforestation, and pollution have greatly increased atmospheric concentrations of water vapor, carbon dioxide, methane, and nitrous oxide, all greenhouse gases that help trSome experts point out that natural cycles in Earth's orbit can alter the planet's exposure to sunlight, which may explain the current trend. Earth has indeed experienced warming and cooling cycles roughly every hundred thousand years due to these orbital shifts, but such changes have occurred over the span of several centuries. Today's changes have taken place over the past hundred years or less. ap heat near Earth's surface.

On the topic of Global Warming I can assure you that it is not man made, or even existed for that matter. Even in this day of age with our advanced technology and super computers Scientist's predictions are based on computer models, and use "flux adjustments" that can be incorrect, as opposed to using historical data. Reliable temperatures only go back 150 years, How do we know the earth is warming in comparison to past temperatures? Earth Naturally goes through warming and cooling cycles.
Even for a second let's pretend Global Warming is real, statistics show that only 0.00022 percent of all CO2 emissions throughout history are caused by humans, this is not nearly enough to prove Global Warming is caused by men. There is no sufficient proof of a link between man made greenhouse gases and global warming.

He's probably got the criteria set to exclude anyone with more than a certain number of wins.

The challenge was not spell checked. There should an extra line after each paragraph to avoid the "wall of text" problem. Sources are essential for a debate that relies on scientific evidence.

NASA is not a good source for temperature data. They keep revising the temperatures upward. HadCRU and the two satellite data sources agree and are lower than the NASA data.

What's with the criteria? I'd love to have a crack at this one!
Can you substantiate your "facts" put forth in your opening statement? Where did you get them? From Al Gore? Your category in't Science....it's Romantic Fiction!

I'm 21 and in the 97th percentile, but cannot take this challenge. What in the world criteria must your opponent meet?
