Global warming is likely (and mostly) anthropogenic


This is for Subutai's environmental tournament. In this debate, I am for the resolution. The BOP will be even since this is a contested issue--BOP shall not be negotiated. The debate structure is first round acceptance, second round arguments (no rebuttals), third round rebuttals/defense, fourth round rebuttals/defense. My opponent is familiar with the wording, and definitions are not needed. Have fun!...
Mankind Is the Main Cause of Global Warming


Full Resolution
I will be arguing that mankind is the not main cause of global warming. We will not be arguing if global warming exists or not, it will be assumed that it does; only if global warming has an anthropogenic cause.
BoP is shared.

Mankind Is the Main Cause of Global Warming

You have asked to debate this first, so I am sending you the challenge directly. My last opponent on this subject forfeited, so I want to try this resolution again. Full Resolution: Mankind is the main cause of global warming. I, as con, will argue that it is of natural causes, not mankind. We will NOT be arguing if global warming exists or not, it will be assumed that it does. Only if global warming has an anthropogenic cause. Definitions: Mankind: "The human race; human being...
The Earth is currently going through a global warming phase.


Definitions. "Global warming phase" – a time period of decent length (compared to a human lifespan) where the average global temperature increases. Over the course of this phase, average temperatures may fluctuate up and down, but the statistical trend is upward (example seen here [1]). In order to qualify, one must be able to extrapolate from the data that the average temperature will continue to increase over the next several decades (pending no action taken to prevent the current trend). S...
Resolved: Countries ought work to end climate change/global warming.


First round acceptance....
Global warming is mostly anthropogenic


Definitions:
Global Warming: An increase in the Earth's average atmospheric temperature that causes corresponding changes in climate
Global warming (full resolution in debate)

Resolution: The MAIN CAUSE of global warming is CO2 emissions made by humans My opponent argues CO2 is the MAIN cause of global warming, I argue it is NOT the main cause. Definitions: CO2 emissions - [emission] A substance discharged into the air, especially by an internal combustion engine.[1] he chemical formula for carbon dioxide, a heavy odorless gas (CO2) formed during respiration and by the combustion or decomposition of organic substances; it is absorbed from the air by plants i...
Humans are the main cause of global warming

The CON must prove humans do not play a significant role in global warming. I recommend a experienced debater that opposes global warming to debate with me. EDIT: Per Ron-Paul's request, the resolution is changed and the voting period is now 1 month. My Starting Arguments: Yes, the Earth is warming. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 "C (1.4 "F), with about two-thirds of the increase occurring since 1980.[1] Is it caused mainly...
To stop the usage of fossil fuel is the only way to combat global warming

Dear Opponent, Thanks for accepting for this debate. Let's start the debate. Fossil fuel has some major impacts in our lifes. It usage has resulted in economic development, job opportunities and environmental issues that is industrial revolution. Today, I will be speaking for the topic. The temperatures have been rising steadily but we have to stop it.rising temperatures is turning the life of living organisms. I agree that there are other causes of global warming but fossil fuel is the m...
