Look at 1959, when the CO2 was 315.98 and Temp was 14.07 Then in 1984, CO2 was 344.42 and Temp was STILL 14.07 And in 1982, CO2 was 341.13 and Temp was STILL 14.07 Then between 1988 and 1989, CO2 went up and Temp went down. Again in 1990 and 1991, CO2 went up and Temp went down. The only "upward trend" I notice is that both data points went up together from 2000 thru 2003. But then 1998 was hotter than 2003, so how did CO2 fall into that equation? Anyway - science tells us that CO2 is a problem, and there are LOTS of other sources of CO2 besides cars.

http://www.oism.org/pproject/s33p36.htm This paper reviews papers that have been published. There are a number of graphs that some of you may find interesting. You will need to read the paper to understand them and I do not claim to have a clear understanding myself. |

Replying to: larsb (Nov 06, 2006 7:19 am) The only conclusion we can draw from that is the Hybrids have caused the increase in GHG

There were about 150,000 hybrids in the WORLD by the end of 2003, of about 500 million + cars and trucks and motorcycles in operation. So, YES, I'm sure they had a MASSIVEglobal warming effect.

Replying to: Mr_Shiftright (Nov 05, 2006 8:50 pm) Well, it would seem to show that higher CO2 levels occur at the roughly the same time as higher temps. Of course, it looks like CO2 levels are up not quite 20% since 1959 (375/315), while global temps are up by 'only' about 3.5% (14.5/14). Is it possible that the elevated CO2 atmospheric content is NOT just from the addition of CO2 from fossil fuels, but also from removing large swaths of earth's rainforest (removing portions of the CO2 sink)?

Replying to: rorr (Nov 06, 2006 11:41 am) I would say yes. We can also add to that the trees that have been removed in temperate climates over the last few hundred years. Some scientist are even suggesting that there may be a problem with burying a lot of vegetation under water in reservoirs behind dams. http://www.commondreams.org/headlines02/0612-07.htm So it appears that cars are just one of many things causing global warming besides methane producing termites and cows. I would make a hot air joke about politicians causing global warming, being that it is the day before elections here in the states, but we all know there is no evidence to support that theory
