Perfect. A science fiction writer talking about the greenhouse effect. That instills more confidence about the accuracy.

He said, in January 1989, the CO2 was .035%. That equates 350 ppm and it is at most 395 ppm today. That’s not too much of an increase is it considering it was 470 ppm around 1943 according to chemical testing done at that time.

Or you could say:

Perfect. A professor of biochemistry from Boston University, Vice Presient of Mensa and President of the American Humanist Association, awarded 14 honoury doctorate degrees, wrote of over 60 science books covering several catogories of science and winning several awards for them. Talking about the greenhouse effect. This instills more confidence about the accuracy. (He did also write a few science fiction books which were also award winning and critically aclaimed, but that's another matter)

He said, in Janurary 1989, the CO2 was .035%. That equates 350 ppm and it is at most 397 ppm today (http://co2now.org). That's too much of an increase consicering it was 310 ppm around 1943 according to the generally scientifically accepted figures, and not the chemical testing figures which shouldn't be considered accurate by any means, as explained here (http://www.ferdinand-eng elbeen.be/klimaat/beck_da ta.html#Accuracy_of_histo rical_CO2_measurement_met hods)

I read the article that you intended to link.

It seems strange to me that they are concerned about the collection methods of the air that was sampled because of variabilities in the time of day, the air being close to the surface, and the wind speed when it was collected; however, they have no problems using ice core samples which have been known to be inacurate without knowing what the wind speed was and the time of day the ice captured the CO2. All the ice samples have air collected near the surface.

Ice core data averages out, whereas chemical testing is a specific moment in time - like the difference between cllimate and weather. LINK

No one can be that stupid. Original123fuk must have an agenda.

Hang on a minute, OK so there is not 1% of the air made up CO2, not even 1/10th of 1% made up of CO2 and even less than half of one of those 1/10ths and of course it is the essence of life on the planet and without that little bit in the atmosphere life as we know it would not exist.
