Scientist says CO2 ‘good for planet’

<<---PRESENT Day is on the left side!!! This chart shows the CO2 levels for the past 500million years.

The two major ways that plants use CO2 are called C3 and C4 photosynthesis. The C3 process evolved first when CO2 levels were at least double today's, from 100M-500+M years ago, and is used by 99% of plants now. About 30Million years ago, the increasing SCARCITY of CO2 gave rise to the C4 process. Even though the C4 plants are only 1% of species, they are much more efficient in this scarce CO2 environment, and yet represent over 5% of plant mass since that 1% of species is 30% better at using CO2 in this rarefied CO2 environment.

As CO2 rises, the C3 process, used by so many plants including many of the "endangered" species, becomes more competitive. No surprise! It was evolved in a MUCH higher CO2 environment!

C4 plants are much better in extreme hot temperatures and drought (read deserts). In normal damp tropical environments nowadays (tropical jungles) they overwhelm the C3s now.

A true ecologist would be cheering for HIGHER CO2 to help the all those endangered C3 species grow better!

The AGW hoax is all about de-developing the developing world.

Today Dear Leader made an excited speech claiming how the US has reduced CO2 release more this past 8 months than ever before! GREAT THING!

Fool doesn’t mention the reason is that the current RECESSION has been the cause of the drop. Recession is temporary de-development. These alarmists are trying to make this type of thing PERMANENT.

However, the drop in CO2 emission they are pushing dwarfs the small decrease caused by this recession.

GLOBAL WARMING HOAX = PERMANENT RECESSION

CarrieOakly? Freeper? former freeper? had written a book on the complexity of nature’s systems and the folly of being able to model them. (Sorry if I butchered this)

If their AGW models were so good, they should have shown the stall and the cooling we have seen in the last 10 years.

What do you think trees and plants breathe?

If somehow we could eliminate CO2 from the atmosphere, we’d all die.

The plants generate our oxygen.

There's a FReeper named CarrieOkie, don't know if that's the one you're referring to

Two great places for objective (should that have to be stated?) scientific information are http://www.discovery.org/v/30 and http://www.globalwarmingheartland.org/ . Also, consider going to the article “Environmental Effects of Increased Atmospheric Carbon Dioxide” at friendsofscience.org/assets/files/documents/robinson.pdf . At least read the Abstract, and consider reading the Summary (about 1300 words). Dr. Arthur Robinson at oism.org is one of the leading voices in this debate and a scientist’s scientist. (Consider subscribing to his newsletter Access To Energy - the best $35/year you can spend.) Arthur’s home-schooled son, Dr. Noah Robinson, presents the video lecture at discovery.org.

Yep...looks like a racist, Obaman-hatin’ teabagger. LOL!

When confronted with Gorebal Warming fear, I bring up the fact that around 1000 AD the Vikings grew grain in Greenland (which is now under permafrost).

I simply ask, "didn't you ever read about the 'Little Ice Age'"?

It is a fact that a person can die from drinking too much water, are we going to start calling water bad or a pollutant?

Dihydrogen monoxide should be banned, and every effort made to eliminate it wherever it occurs. I can't think of any other chemical that is more destructive of human life. Not only does it suffocate people, but it damages property so catastrophically that often people who do not suffocate die from being hit by the debris or trapped in it.

Actually, I’m wondering at what concentration of CO2 would it become impossible for plants to function?

Since chemical reactions are driven by the relative concentration of the reactants on each side of the equation, that would be interesting to know.

It worries me when I read about schemes not just to reduce CO2 production, but to sequester it from the atmosphere. China has a carbon sequestration plant either currently or soon-to-be operational. How much CO2 can be sequestered before shutting down photosynthesis? What minimum concentration of CO2 will still support plant life?
