Do you believe NASA & NOAA when they say CO2 rates have doubled since the 50s? This question seems to scare a lot of people on this board.Harrison Bergeron said:That seems to be pretty important. If one is going to argue for taking a particular action, one should understand the benefits and risks of said action. If anyone is going to advocate that we should reduce carbon emissions, there should be a pretty good, data-driven "why" and a quantifiable results if all these actions occur.Osodecentx said:Are you saying that CO2 has not doubled since the 50s? I believe NOAA and NASA. Those are actual measurements, not assumptions.Harrison Bergeron said:Osodecentx said:Changes in past atmospheric carbon dioxide concentrations can be determined by measuring the composition of air trapped in ice cores from Antarctica. So far, the Antarctic Vostok and EPICA Dome C ice cores have provided a composite record of atmospheric carbon dioxide levels over the past 800,000 years.Harrison Bergeron said:Correct. There can be selective measurements of CO2 but nye impossible to measure the entire atmosphere ... much like how the location of temperature stations can impact temperature readings.Oldbear83 said:
You are not addressing the main point., It doesn't matter worth a fart what happens with CO2 unless CO2 is proven to be dangerous.
And if you are contending that scientists in 1950 considered carbon dioxide a threat, they sure hid it well, because I cannot find a single meterological journal claiming so before 1975, and zero experimental evidence anywhere to back up the claim.
As for whether there is more or less carbon dioxide now than in 1950, that depends on how, where and when scientists measured. Given that there is zero evidence it was considered a danger in 1950, I'd submit common sense drives less effort to find or track it in 1950, and ergo there is less evidence of it.
The only thing you have proven is you've got the Vapors, son.
But still trying to understand how we have CO2 measurements from 100, 200, or 800K years ago.
If we stopped all man-made carbon emissions today, how much would that reduce the global temperature in 100 years?
I have said nothing about the effects of the doubling of CO2. I have no idea on what happens to the global temperature with your hypothetical. What do you think?
I prefer Occam's Razor:
- the same people telling us we were going to be in an ice age 50 years ago now are telling us all the ice will melt
- the people that told us polar bears would be extinct don't realize the population of polar bears has been growing
- the people that told us the world would end by 1990. 2000. 2020, are still making up new hysterics
- the same people that advocate cutting domestic oil production are just buying billions from Putin, Iran, Venezuela, and other bad Middle East actors
- the same people worried about "carbon footprints" fly private jets and live in mansions
- the same people that tell us the sea levels will flood American live on the water
At some point common sense just lets one realize you're being manipulated and lied to.

If atmospheric CO2 has not increased there is no reason to do anything.
Occam's razor is a principle of theory construction or evaluation according to which explanations that posit fewer entities, or fewer kinds of entities, are to be preferred to explanations that posit more. Your explanation seems complex, not simple and straight forward
