Again... plants need CO2. Less CO2 = less growth, less life.
Scientists confirm basic physics - CO2 makes it hotter.

Are you claiming there was no CO2 until man started putting it into the atmosphere?
No. I'm claiming CO2 is part of the cycle of life.

I think we all know that. I'm talking about your claim that man preventing more CO2 is helping deforestation. Care to address that or are you going to continue to feign ignorance.?
Again, and I'm not sure what part of this is confusing you about my statement. More CO2 in the atmosphere = more and bigger plants. REDUCING CO2 in the atmosphere is equivalent to REMOVING mass from the aggregate amount of plant life on the planet.
Plants store and use the CO2 they get from the atmosphere to grow. Less CO2 in the atmosphere means the plants have to work harder to grow. And not just "vines." That's a silly myth.

The part thats confusing me is your illusion we can remove anything but our contribution of CO2 and the claim you made saying it helped deforestation by doing so?

RK, here's evidence that flat out refutes your mythology. If you disagree, post your evidence now. And remember, whining is not evidence.
How d They Do That Poison Ivy and Carbon Dioxide Studies - Boing Boing
---
Both trees and poison ivy grew faster, when exposed to higher concentrations of CO2, than their oxygen-only counterparts. But poison ivy grew faster than the trees--150% faster, in fact, compared to a 20% increase in tree growth. The difference, according to Jackie Mohan, is that poison ivy, like all vines, is a bit lazy.
"Vines don't need to devote so much of their CO2 resources to growing these big, woody trunks," she says. "Instead, they can devote that to growing more green leaves, which increase photosynthesis some more. And it becomes a cycle."

Study Vines crowding out trees in tropics harming CO2 balance
---
The report, published online last week in the journal Ecology Letters, surveyed eight studies on the state of woody vines in tropical forests from the Savannah River system and the Congaree National Park in South Carolina to an area in the central Amazon about 50 miles north of Manaus, Brazil. They found that in all forests, vines were increasing in abundance, biomass or both.

Carbon dioxide could reduce crop yields
---
The plants, which ensure our basic food supply today, have not been bred for vertical growth but for short stalks and high grain yields. Scientists from the Max Planck Institute of Molecular Plant Physiology and the University of Potsdam have now discovered that an increase in carbon dioxide levels could cancel out the beneficial effects of dwarf varieties.

High CO2 Makes Crops Less Nutritious
---
In the largest study yet, Samuel Myers of Harvard University and colleagues report that the CO2 levels expected in the second half of this century will likely reduce the levels of zinc, iron, and protein in wheat, rice, peas, and soybeans. Some two billion people, the researchers note, live in countries where citizens receive more than 60 percent of their zinc or iron from these types of crops. Deficiencies of these nutrients already cause an estimated loss of 63 million life-years annually.

Climate myths Higher CO2 levels will boost plant growth and food production - environment - 16 May 2007 - New Scientist
---
However, while experiments on natural ecosystems have also found initial elevations in the rate of plant growth, these have tended to level off within a few years. In most cases this has been found to be the result of some other limiting factor, such as the availability of nitrogen or water.

Climate change surprise High carbon dioxide levels can retard plant growth study reveals 12 02

But an unprecedented three-year experiment conducted at Stanford University is raising questions about that long-held assumption. Writing in the journal Science, researchers concluded that elevated atmospheric CO2 actually reduces plant growth when combined with other likely consequences of climate change -- namely, higher temperatures, increased precipitation or increased nitrogen deposits in the soil.

Not sure why you have the desire to turn everything I say upside down. Please cite where I said "we can remove anything but our contribution of CO2" and "it helped deforestation by doing so."
No one can be as dumb as you are pretending to be.
The first effing sentence you cite states:
"Both trees and poison ivy grew faster, when exposed to higher concentrations of CO2."
WHAT PART OF YOUR DEFENSE OF MY STATEMENTS WHILE ATTEMPTING TO ATTACK THEM IS CONFUSING YOU?
Why so much damn hatred???? Stop bashing and use your heads for something good for once.No idiot. The point is that man is causing another rise in CO2. Doesnt matter what or who is caused the last one. Were you born a ******* idiot or did you become one via environment?I'll ask this question one more time...wonder how all that human caused carbon dioxide accumulated 25,000 years ago when the CO²/solar radiation was so great as to melt the glacier which NOT ONLY covered what is now CANADA but also almost half of the United States...southward down to approximately northern Kansas and Missouri.
It wasnt humans moron.
The Last Time CO2 Was This High Humans Didn t Exist Climate Central
Which is the entire point you stupid son of a *****.
You are the dumbest mother fukker I believe I've ever run into on a forum board. There is no use even trying to make sense to your ******* idiocy.

In the first link, the part with "the vines grew 150% faster, the tree 20%" would be what conclusively debunks your crazy claims. The rest of the links there also pointed out how your claims were a fantasy, but you were apparently too flustered to go any further. I understand. Learning that your cult bamboozled you and that everything you knew was wrong must have been a shock.
It would if the world was a small experiment over a short period of time... however, I understood the difference between something that lives for decades, such as a tree, and something that dies off each winter like a vine. Do you? Maybe you could explain that one to the class.
sigh...

Maybe you could explain where you got the strange idea that vines die each winter.
Most large vines don't. The only large vine I can think of that sees some cold dieback is Kudzu. In my zone, the Wild Grapes, Poison Ivy, Virginia Creeper, Japanese Honeysuckle, Moonseed and Trumpet Vine are all just like the trees, dropping leaves in the fall and resuming growth in the spring. And the English Ivy is evergreen.
And in the tropics, there is no winter.
So, the vines explode, they smother the trees, resulting in a net loss of carbon fixing.

I see, so you are trying to tell me that during warmer times back when CO2 concentration was much higher than it is today that the earth was covered with nothing but vines and there were no trees.
Note: mammoth says all the trees were made extinct by man over most of the last 500million years because man caused CO2 resulted in all the vines choking out all other plant life. Amazing information there mammoth.
Where's the runaway CO2 effect? How did life on earth survive for hundreds of millions of years with CO2 4-15 times higher than it is today? Everything learned to live off vines?

The atmosphere is NOT A ROOF... A roof stops convection and escaping radiation, Our atmosphere does not... You really are a fool..

Don't make up weird stories about what I supposedly said. It makes you look desperate.
Why do you think there's supposed to be a runaway CO2 effect? Where do you get this stuff?
A younger sun was a fainter sun. 500 million years ago, the sun was 4-5% dimmer. The extra CO2 countered the dimmer sun. Prior to that, when CO2 was low, there was snowball earth.
So, nice work there, the way you demonstrated the warming effects of CO2 by paleoclimate evidence.

Hmmmm....let's see now. OK, I think I've got it. Because Asclepias is the dumbest mother fukker I believe I've ever run into on a forum board. There is no use even trying to make sense to the ******* idiot.
May I help you with any other questions?
