| Nov 6, 2017 at 22:10 | comment | added | Charlie Jiang | @bon CO2 and CH4showed strong correlation with global temperatures. But: 1. It is not a cause relationship. It can be explained as the temperature change is the cause to the change of CO2. 2. You have assumed that ice core record is contiguous. Any warm years could wipe out thousand years of record. 3. if the correlation is correct. then about every 100 ppmv CO2 increase will increase temperature 9'C. Now the CO2 increased from 300 to 400 ppmv, does the temperature increase 9'C? | |

| Feb 16, 2016 at 21:45 | comment | added | bon | @CharlieJiang In a simplified model, climate is a reflection of conditions in the troposphere but as I said before it is influenced strongly by processes in the oceans, on land, in the stratosphere, tectonic processes, etc. Unfortunately, we can't model climate perfectly yet (and never will be able to) but we are making steady progress through the use of computer modelling and interpretation of paleoclimatic data in order to test the models. | |
| Feb 16, 2016 at 21:33 | comment | added | Charlie Jiang | @bon : As I am told here, if you figure out how to simulate the atmosphere, Nobel prizes and billions of dollars await you. Even if you can only simulate the Troposphere that would be a great advance in human knowledge, because that is where the climate is. | |
| Feb 16, 2016 at 15:41 | comment | added | Pont | @CharlieJiang You say "Only direct measurements from simulated atmospheres will convince me." And yet, in other comments, you confidently tell us about the CO2 levels in "the dinosaurs time atmosphere", which are reconstructed using sedimentary records just like the ones you reject here. So it seems that for you, palaeo records are sometimes reliable... but only when they happen to serve your argument at that particular moment. | |
| Feb 16, 2016 at 12:34 | comment | added | bon | @CharlieJiang Yet you have no evidence for your belief and you dismiss any evidence against it as poor quality or 'theoretical'. Your argument is purely based on opinion. | |
| Feb 16, 2016 at 12:31 | comment | added | Charlie Jiang | If one believes CO2 changes climate, one would worry CO2 being released too fast. I do not believe it, I do not worry it. I truly appreciate the opportunity allowing me to voice a different opinion. | |
| Feb 16, 2016 at 12:30 | comment | added | bon | @CharlieJiang I disagree. The Earth's climate system is far too complex to simulate in a lab experiment. It is not enough just to put the contents of the atmosphere in a flask and vary the $\ce{CO2}$ concentration. This is in no way representative of the Earth's atmosphere as it ignores the very strong coupling with other parts of the climate system, namely the hydrosphere, cryosphere, lithosphere and biosphere. | |
| Feb 16, 2016 at 12:27 | comment | added | Charlie Jiang | @bon: Thanks for your patience. I am told not to question answers here. So I will make a few statements. To me, the lab works from anent ice core or sediments are indirect data collection which requires many precision steps. There were many unknowns in millions years, e.g. volcanoes, meteors.... Even though we think we have explanations. I must be an odd person. I have my reasons and evidences. Only direct measurements from simulated atmospheres will convince me. That is a much easier work than the lab work you've done. | |

One plausible theory (though not the only one) is that large volcanic eruptions under coal beds added large amounts of CO2 to the atmosphere. | |
