It's exactly the same thing for each and every element, and too much CO2 leads to plants literaly dying of suffocation. Though it's not the main problem of CO2 pollution, but you're maybe in the same guideline as the others idiots explaining that "NASA is lying that's all"...
So, ignorant on effects of CO2 and O2 partial pressures, refuse to consider Trenberth's admissions, what else can you be ignorant or wrong about?
Lol, try operating a greenhouse some time.
Doubling or tripling CO2 certainly does increase plant growth considerably.
http://www.omafra.gov.on.ca/english/crops/facts/00-077.htmincreasing the level above 340 ppm is beneficial for most crops. The level to which the CO2 concentration should be raised depends on the crop, light intensity, temperature, ventilation, stage of the crop growth and the economics of the crop. For most crops the saturation point will be reached at about 1,000–1,300 ppm under ideal circumstances. A lower level (800–1,000 ppm) is recommended for raising seedlings (tomatoes, cucumbers and peppers) as well as for lettuce production. Even lower levels (500–800 ppm) are recommended for African violets and some Gerbera varieties. Increased CO2 levels will shorten the growing period (5%–10%), improve crop quality and yield, as well as, increase leaf size and leaf thickness. The increase in yield of tomato, cucumber and pepper crops is a result of increased numbers and faster flowering per plant.
Regarding O2. Numerous spacecraft have operated with pure oxygen - 100% oxygen. The danger from this is obviously fire.
If total pressure exceeds 1.6 atmosphere, that is bad.

Hi all
Well I have my own article on
where the heck is global warming? We are asking that here in Boulder where we have broken records the past two days for the coldest days on record. We had 4 inches of snow. The high the last 2 days was below 30F and the normal is 69F, and it smashed the previous records for these days by 10F. The low was about 18F and also a record low, well below the previous record low. This is January weather (see the Rockies baseball playoff game was canceled on saturday and then played last night in below freezing weather).

The fact is that we can’t account for the lack of warming at the moment and it is a travesty that we can’t. The CERES data published in the August BAMS 09 supplement on 2008 shows there should be even more warming........

Oh, and the Stephen Schneider in his email list? Let's take a look at one of his little opinions.
On the one hand, as scientists we are ethically bound to the scientific method. On the other hand, we are not just scientists but human beings as well. To do that we need to get some broad based support, to capture the public’s imagination. That, of course, means getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. Each of us has to decide what the right balance is between being effective and being honest.Could it be that you simple fell for some of those "Scary Stories?"
LOL...
