The more CO2 we emit, the warmer the average global temperature is likely to become.
However, the real question is...is a warmer climate necessarily bad? There exists demonstrable causation between CO2 emissions and warming, but is there demonstrable causation between warming and disastrously unpleasant conditions?
My friends, I'll leave you in the trusty hands of David D. Friedman. |

One volcanic eruption sends forth enough gases to make global warming gases seem like some vapor fart in comparison.
We should outlaw volcanoes. |

If there are aliens out there, chances are they may be like us.
Expansionist, territorial, greedy for loot and fame, xenophobic.
They'll either hit us with treaties, or war. |

Bullsh*t is fun to say, but hard to back up.
The USGS estimates 200 million tons of carbon dioxide comes from volcanoes each year (1), compared to 30 BILLION tons of carbon dioxide from human activity (2). Note that the 200 million tons is the average for ALL volcanoes per year, not one.
But then "ignorance is strength" anyway, right? |

That's fine. But if the discussion is about "greenhouse gasses", then it is not limited to CO2 (which volcanoes have produced much more of over hundreds of millions of years than humans). It would also include the most important and abundant greenhouse gas in the atmosphere: water vapor, which is the main gas given off by volcanoes. CO2 is negligible by comparison, and on a geological time scale we are currently CO2 starved.
What insignificant amount of CO2 we humans do produce merely creates a small benefit for the world's plant life, and beyond that, any effect it has on climate change ranges from slightly beneficial to completely negligible. The barely measurable effect of CO2 does not even compare to the much stronger greenhouse effect of water vapor. There is no convincing evidence to the contrary. |
