manmade activity is probably a significant cause of global warming
detractors from MMGW man made global warming, who say it's not ssignificant, and only a hoax, usually rely on sun flares and volanoes. essential facts. one is that studies have shown that the sun cycles have accounted for only a third of the warming that's occurred. the other is that the volcano theorists have never cited sources... and sources that can be found show that they produce only a small amout of heating. i've never seen any sources cited for the volcano theory, but here's wha...
Global warming a "Human cause?"
Debate will start off with me stating my position (In short) then the PRO will put in his/her position in short. The position should be like a quick thesis statement. My position in SHORT: Global warming is a natural process with little to no influence from Humans....
The sun is the main cause of global warming
No semantics or trolling, this is to be a honest debate with serious attitudes. I would usually argue pro, but I am devils advocating. I argue the sun is not the main reason for current climate change, my opponent argues the sun is the main reason for current climate change. Current global warming is from the last century, though data from before then is welcomed as evidence as long as it relates to the now. 1st round acceptance. good luck!...
Resolved: Global Warming Exists
As we have agreed to it, here is the challange. ...
Global warming
The government needs to take the issue about Global Warming more seriously! This can lead to serious consequences in the future and needs to be reduced....
Man made global warming is a myth.
I would like to invite someone to prove how man is at the cause of global warming. I agree that global warming exists, but not that it is a result of mans actions here on earth. I believe that global warming is a part of a natural cycle of cooling and warming that the earth constantly goes through.. I'm not very interested in links, though you can use them. Anyone can show a link and a counter link. The only time I recommend links is when you are including something that you think is a fact such...
Electric cars should be a priority in plans to fight global warming
The debate will go in the following order: Round one: Intro Round two: main round/ Case Round three: CX Round four: conclusion. My opponent will answer the following questions as well as use these questions as a base for his contentions: Are electric cars helpful in fighting global warming? Are electric cars economical? Are electric cars compatible with electric grids? Are electric cars reliable? Thank you....
Anthropogenic Global Warming Is Real
First off, I want to thank Con for offering to take up this debate. This resolution is based on a discussion that originated in the comment section of another debate: http://www.debate.org/debate/13812/ == Definitions == Anthropogenic Global Warming (AGW): Global Warming influenced by human activities. Real: Being or occurring in fact or actuality. == Rules == Pro and Con will both refrain from attacking the sources of scientific information in order to keep this debate focused...
Global Warming is Chiefly caused by Natural Phenomenon and NOT Humans
I'll start this off with a background of the issue. *** Background: Some disagree on the degree to which global warming might also be caused simply by natural changes in the earth's climate. Some claim that humans are the chief cause of the warming that has occurred over roughly the past century, while others claim that our role has been relatively insignificant as compared to natural forces. Therefore, the debate roughly defined here centers on the question of whether human are the "c...
The human effect on global warming is significant.
I'm not sure how well I worded the debate resolution, so I will explain further. This is a scientific debate about whether humans are driving global warming and whether it is a problem. And so as not to cause any confusion, I hereby discredit Al Gore. Any arguments that cite Al Gore as a source should be ignored. Definitions Human effect: Effect caused by unnatural human actions; this includes sources such as factories and power plants but excludes sources such as natural respiration. Glo...
