Very interesting, Neal. Thanks for teaching.

 

Nice job guys. I never even knew that about the volcanoes or c02 being so rare in the atmosphere.

If anyone dosnt believe these guys, then hear it from the wisest of the wise:

I just sent this to all my students !

Now for the test question: Why is CO2 so rare a gas if over 6 billion people and countless gazillions of animals are breathing it out, as well as all the electric plants, autos, trucks...etc...etc..etc?

 

Holy cow, I started a thread just because I think too many people are like lemming's and I end up needing a PHD just to understand most of the replies.

 

Im gonna have to guess due to photosynthesis?

 

DING...DING...DING...We got a winner! That's absolutely correct and the next time you are in northern Nevada the adult soda pop is on me! Go back to the short lecture and you will see references to ecosystem (biospheric) regulators...the chief regulator of CO2 depletion is photosynthesis and the chief regulator of CO2 addition is all living things which consume others (heterotrophs).

 

Actually a lot of scientists argue that the rise of CO2 is a result, and not a cause of, a warmer climate.

 

True, but I have always been a believer that the simplest explanation of any phenomenon is the best one in absence of evidence to the contrary. The fact that we are pumping billions of tons of CO2 a year seems to me to be the simplest explanation for a CO2 increase that coincides with human industrialism. I'm also not convinced our climate (on a geologic time scale) is actually changing any more rapidly than it was before the Industrial Revolution.

 

Well the simplest may be the best answer and the simplest is that fact that raises in CO2 Levels are natural not man made. Why do I say that? simple even the ones that are pushing man made global warming will admit that CO2 Levels have risen intermittently throughout history around the time that the temps rose thus the simple truth is that it does it whether man is here or not so the complex hard to swallow answer is that man is the cause.

One thing to look at here real simply is that it's known and proven fact that the global temp has been raising for several hundred years, yes may not have large quatities of data but you can check it with trees, with ice cores (the cores that check the CO2 levels can also tell much about the temp at that time too) etc so now if you believe it's man made then you have a situation where the result predates the cause. So how can it have any truth to it with the above mentioned facts that are even published by those pushing the man made agenda?

Also you mentioned simple, how about the fact that Al Gores chart shows timeline sorta (he neglets to let you see the missing spaces) but it shows the temps beginning to rise before the CO2 levels in past times of global warming, now the current group would have you believe that was man causing CO2 emissions? not hardly, and this is the reason that many scientist are beginning to question the man made part do to CO2 emissions, history is not on Al Gores side.
