At the level of 1% concentration of CO2 (10000 ppm) some people will begin to feel some effects. At a level above 5% concentration of CO2 (50000 ppm) it is directly toxic and will kill you rather quickly. EDIT: I see Rob Smith beat me to some of this information. Takes me a while to make posts sometimes. I keep getting interrupted by other, more important things. Currently, we are at about 400 ppm (0.04%). How much is too much? THAT is what the debate here is about. Fair point Kong, and taken to heart. But never the less it was you who said---life went on. Yes, life went on. But there is no guarantee that humanity will. Yes, life will go on, *unless* we trigger a 'nightmare' scenario of a runaway greenhouse effect similar to what happened to Venus where the surface temperature is hot enough to melt lead. This, however, is extremely unlikely. Venus' atmosphere is MUCH denser than ours, and it is over 95% CO2. How much is too much? There are those that say *any* human influence on the climate is bad. Well, that ship sailed thousands of years ago (somewhere between 15000BCE and 5000BCE or thereabouts) during the Agricultural Revolution. Human activity changes the climate. How much is too much? There are others that say that we should try to restrict the climate from changing more than 2 Degrees C warmer. Well, that ship has likely already sailed as well. If we totally stopped *all* human activity that even potentially produces climate change TODAY, the climate would likely take several thousand years to fully 'recover'. How much is too much? I have no clue. |

You are talking rubbish - the facts do not align with your ill formed theory. The change in atmospheric carbon has JUMPED in the last couple of hundred years, far faster than at other comparable period of time. In that time man has burnt millions of tons of fossil fuels (coal, gas, oil). That combustion has released into the atmosphere about three times that mass of carbon dioxide. Some of that has been absorbed by the oceans, some by plants, but the vast majority is still in the atmosphere. Current CO2 concentrations are hardly double the pre-industrial 300ppm. http://www.esrl.noaa.gov/gmd/ccgg/trends/weekly.html We are only right at about 400ppm now.. In fact, the March 25 daily average (yesterday) WAS 400.00ppm. |

I have no clue--you said. Honest answer, thank you for that anyhow... Must not conflict resolve by suggesting that someone should go sit on an ice pick... |

But my dear, Co2 is not trash. You exhale it. LMBO! It is part of our bodily functions. Hi Julie :) Nice to see you (and of course everyone else too!) I sense, like me, that you like trees? :) and they do need C02 to exist - but since my post last night a further 13,227 hectares of forest was destroyed. That's less C02 needed to keep them alive - and of course now they're no longer living, they'll release a lot of their locked up carbon, and more will be generated clearing them from the land they were growing on and so on and so forth. :( |

Hi ID, sorry for late reply, only just got home :) my exhaled CO2 doesn't come out grey and/or black and jam packed with toxins (as far as I know - how can I get that verified?) although I think I might be coming down with a cold, so there might be some germs in it :) or :/ or :( |

the following quote is from NASA Climate change: How do we know it is caused by humans and really happen ? ![]() This graph, based on the comparison of atmospheric samples Certain facts about Earth's climate are not in dispute: ◾ The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. Increased levels of greenhouse gases must cause the Earth to warm in response. ◾ Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in solar output, in the Earth’s orbit, and in greenhouse gas levels. They also show that in the past, large changes in climate have happened very quickly, geologically-speaking: in tens of years, not in millions or even thousands. 3 Scientific Consensus Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities, and most of the leading scientific organizations worldwide have issued public statements endorsing this position. Click here for a partial list of these public statements and related resources. The evidence for rapid climate change is compelling: Good Night ... or morning ... or afternoon to all in our SETI@home community, where ever you happen ... to be on our only home ..... tiny little planet Earth :) be kind and gentle to one another ... and ...

LOL... Point taken on the trees. But they are not the only ones who take up carbon and let out O. average 'hectare' of corn removes 22 tons of carbon dioxide from the air. Trees will sequester atmospheric carbon dioxide at an average of 50 pounds of carbon dioxide at an an average of 1,000 trees per hectare When the tree dies it leaves more carbon behind then a corn plant does. This effect evens itself out as we can see... :-) Must not conflict resolve by suggesting that someone should go sit on an ice pick... |

I have no clue--you said. And neither do you so you advocate letting it ride and find out. |

I advocate doing nothing because there isn't a problem, one that we can fix by even a fraction one way or the other. We have a zero impact in carbon in the air. The forces of nature are what they are. We cannot change them in any way, shape or form. We cannot Terra Form a planet, we are not that advanced as a race and wont be for many a year... ...just that simple.

LOL, because we are still on this rock. That is why I know we have not advanced enough to make a differance one way or the other. Must not conflict resolve by suggesting that someone should go sit on an ice pick... |

Current CO2 Level on graph looks like a Redwood amongst Dogwoods. DENIED HuWoMan Are LIARS and Prone to BIG MISTAKES. Their Data 'is' BIASED and AGENDATIZED. Therefore, NO BELIEVE.

Air is Breathable and Water is Crystal Clear. Says a man who's never been to Izmir, Bangkok or Beijing. I have, and you don't breathe the air there, you bite off a lump and chew. Then there's the Great Pacific Garbage Patch, plus similar situations in the Atlantic and other oceans. There's no denying humans have had a very negative effect on parts of this planet. Life on earth is the global equivalent of not storing things in the fridge. ![]() |

Air is Breathable and Water is Crystal Clear. I know, sometimes it seems like it's no use. Too many people only have eye for money and their own greed, they don't think of the consequences their actions have or what it does to Mother Earth. And then you indeed have the 'emergency countries' who just don't have the means to do anything, so sad... rOZZ Music Pictures |
