Humans are causing the rise in clobal temperature, which if not stopped will result in global warming.

For the record- I believe in Global Warming (not all theories, but the basic premise of most). What I don't believe in is feeding the conservative view of global warming with lackluster arguments in favor like "humans are causing the rise in global temperatures" which can be easily debated against.

I will debate against my opponents simple statements with simple statements of my own, as well as a rebuttal.

"Humans are causing the rise in clobal temperature"

-This is impossible. Yes, humans give off heat, but unless you can prove that our collective body temperatures are somehow raising global temperatures, then this statement cannot be true.

" Humans are causing the rise in clobal temperature, which if not stopped will result in global warming."

-The natural cycle of global warming cannot be stopped. For thousands of years the Earth has had a warming period in which the ice caps melt, the sea levels rise, and weather patterns are drastically affected which in result cause global cooling- the Earth's natural protection mechanism which brings about periodic ice ages. Because of the dynamic between our atmospherical makeup, our proximity to the sun, and other factors like the moon's effect on tides- global warming cannot be stopped.

Yes it is true that Global Warming cannot be stopped. It is also true that
it has recently gone up more in the 20th century then it has before. Why do you think that is if not because of the constant burning of fossil fuels humans burn daily. This lets off too many gases into the atmosphere which causes the green house effect which results in Global Warming.

Why don't we define Global Climate Change:
Climate change refers to any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). Climate change may result from:
•Natural factors, such as changes in the sun's intensity or slow changes in the Earth's orbit around the sun
•Natural processes within the climate system (e.g. ,changes in ocean circulation)
•Human activities that change the atmosphere's composition (e.g., through burning fossil fuels) and the land surface (e.g., deforestation, reforestation, urbanization, desertification)

Notice the part where it says "human activities". As you can clearly see, humans are a huge factor in Global Warming.

"It is also true that it has recently gone up more in the 20th century then it has before."

-According to the EPA: "Records from land stations and ships indicate that the global mean surface temperature warmed by between 1.0 and 1.7�F since 1850 (see Figure 1). These records indicate a near level trend in temperatures from 1880 to about 1910, a rise to 1945, a slight decline to about 1975, and a rise to present (NRC, 2006)."

Now, the problem with this is that there was not a decline, rather a rise, in CO2 emissions between 1945-1975, so it is nearly impossible to pin the blame on any one factor, particularly humans. The EPA also states that: "Between roughly 900 and 1300 AD, evidence suggests Europe, Greenland and Asia experienced relative warmth. While historical accounts and other evidence document the warmth that occurred in some regions, the geographical extent, magnitude and timing of the warmth during this period is uncertain (NRC, 2006). The American West experienced very dry conditions around this time."

This all occured BEFORE the industrial revolution, and before humans could possibly have any significant effect on global greenhouse gases. According to the EPA, though there is confidence within the scientific communit, there is not enough evidence to assign human fault in recent climate change: "Present evidence suggests that temperatures at many, but not all, individual locations were higher during the past 25 years than any period of comparable length since A.D. 900. However, uncertainties associated with this statement increase substantially backward in time." That's just referring to the last 25 years, and discounting the drop in climate between 1945-1975.

"Why do you think that is if not because of the constant burning of fossil fuels humans burn daily."

-Well, thanks for asking what I think. I think the Earth has a natural cycle of warming and cooling. I believe the Eearth has natural elements which control the percentages of greenhouse gases in it's atmosphere which regulate the temperatures between cooling periods (ice ages), warming periods (like now), and stable periods. There is enough evidence to suggest that humans are a contributing factor in a significant rise in the amounts of greenhouse gas emissions in the atmosphere, but the sharp rise in greenhouse gases in the atmosphere does not coincide with the slight rise in global mean temperature.

"This lets off too many gases into the atmosphere which causes the green house effect which results in Global Warming."

-The "greenhouse effect" is a GOOD thing. Any planet with an atmosphere has a "greenhouse effect"... otherwise the Earth would be like the moon. Global warming is also a GOOD thing. Can you imagine what the Earth would be like if it wasn't naturally insulated???

"Notice the part where it says "human activities". As you can clearly see, humans are a huge factor in Global Warming."

-You didn't prove this, you simply stated this. Even if you were right, you are now contradicting your original statement. A "huge factor" is not en exclusive cause as you suggested in your statement: "Humans are causing the rise in global temperature". It also is contradictory to the entire statement: " Humans are causing the rise in clobal temperature, which if not stopped will result in global warming."

Here are a few points you have failed to prove:

-Humans are causing the rise in global temperature
(Not true. The natural warming and cooling cycles of the planet, our current place in the warming/cooling timeline, and other natural anomalies are at least mostly responsible for any significant rise in global temperature- even by the estimates of the most staunch global warming scientists)

-Humans are causing global warming.
(Not true. This is completely false and impossible. Humans are not greenhouse gases, nor are we a part of the atmosphere. We are not the Sun that shines on the earth, we are not the ocean that traps and releases CO2 according to mean global temperatures, and we are not a part of hundreds of other natural factors that create the beneficial process of global warming)

Now, for those of you who are too liberal and hardheaded to read a debate before voting on your own opinion- I am not saying greenhouse gas emissions should not be regulated. I am not saying that the global temperatures WON'T rise to higher levels, and I am not saying that humans do not contribute to greenhouse gas emissions. What I am saying is that the environmentalist position is misunderstood by many, and thus causes conservatives to disagree with and dismiss the issue of global warming. We must address the issues that are facts- greenhouse gases are required to promote the natural occurence of global warming. Greenhouse gases have risen by more than 38% in the past 100 years. Even if we cannot personally account for that 38% increase, we have the power to regulate further increases so that we may better aide in the stabilization of the presence of greenhouse gases so as to prevent the POSSIBILITY of an alarming increase in global temperatures.

Stop the fearmongering and deal with the issues according to the facts (that applies to conservatives and liberals alike).

sophia-timpson forfeited this round.
Mangani

Con

Even though my opponent forfeited her last round (for obvious reasons), I will reiterate my rebuttals to her opening statement and premise of this argument:

"global climate change is human caused"

-I presented scientific arguments from liberal as well as conservative sources disproving this premise. My opponent (who, as Pro, has the burden of proof) never presented one argument in favor of this premise. My opponent contradicted this statement with the following "Climate change may result from:
• Natural factors..."

"Humans are causing the rise in clobal temperature"

-Again, I presented scientific arguments contrary to this statement, even though my opponent never presented any scientific arguments in favor of this statement. I suggested it was impossible for humans to "cause" global climate change, which occurs and has occured without the presence of humans on this planet (according to scientific evidence from both liberal and conservative sources).

"which if not stopped will result in global warming."

-I presented arguments denouncing this statement. Global warming cannot be, and should not be stopped. If the Earth did not have a natural mechanism to warm it's climate, life on Earth would be impossible.
My opponent conceded this with the statement "Yes it is true that Global Warming cannot be stopped." presented in Round 2.

Not only did my opponent not present any scientific arguments in favor of her premise, she contradicted statements she intended to support her premise.

It amazes me that global warming is still so poorly understood.

And, global warming could of course be stopped by any of dozens of mechanisms:
- solar reflectors in space
- mist generators on the ocean
- sulphate particulate emissions

Reducing man-made greenhouse gas emissions is of course the best choice as it attacks the problem rather than the symptom.
