and human produced CO2 is even less significant.


well, thanks to humans the ammount of co2 in the air has increased by 20% over the last 50 years
and thats a hell of a lot of co2

and to quote wikipedia:
NOAA states in their May 2008 "State of the science fact sheet for ocean acidification" that:
"The oceans have absorbed about 50% of the carbon dioxide (CO2) released from the burning of fossil fuels, resulting in chemical reactions that lower ocean pH. This has caused an increase in hydrogen ion (acidity) of about 30% since the start of the industrial age through a process known as “ocean acidification.” A growing number of studies have demonstrated adverse impacts on marine organisms, including:

The rate at which reef-building corals produce their skeletons decreases, while production of numerous varieties of jellyfish increases.
The ability of marine algae and free-swimming zooplankton to maintain protective shells is reduced.
The survival of larval marine species, including commercial fish and shellfish, is reduced."

Thanks for bringing up other effects of CO2 increase. I do not believe in it contributing to the global temperature in a serious matter (quite the opposite, temperature increase, increases CO2 natural production) but it might affect life in other ways, possibly harmful as you have pointed out.

http://dangerousintersection.org/wp-content/uploads/2006/09/CO2-Tem... This is often pointed out as a proof of CO2/temperature relationship. Careful examination shows that it's the CO2 that lags after temperature.

Your are spewing out the usual climate denial junk we expect to see from the wattsupwiththat crowd as well as the various conservative think tanks funded by Exxonmobile,the Koch brothers or the tobacco industry at the Heartland Institute. Are you a stool for those interests or can you study think for yourself.

If what you say is true, write a paper on all your beliefs and get it published in a peer reviewed journal. You will find your points have all been debunked.

It is one thing to be a conservative/republican, it is quite another to buy into the idea that conservatives automatically have to work for free for Koch industries to promote coal and fossil fuel burning.

It is a simple fact humans have increased CO2 levels from around 250 to 460 ppm since the industrial revolution started, nature can not do so that fast. Since China and India have joined the energy party, we are likely headed to 700 ppm in the next century with no stopping. Last time CO2 levels were this high due to nature, was eons ago when life and flora was very different.

And yes CO2 is good for vegetation up to a point. It is also a trace gas, and physics says CO2 is a warming gas although water vapor and methane are much worse. The Oxygen, Nitrogen, Argon that make up the bulk of the atmosphere are not warming gasses so indeed the remaining gasses can and do make a huge difference.

The CO2 normally cycles through the system over very long periods of time, about the same amount goes into the atmosphere as is taken out by natural processes. The human load is just a small push of a few percent but it is always adding, so the CO2 level drifts upwards, that is simple integration math.

I could go on but you could learn more from your own research.

Personally I think that the only way to a future of guilt free plentiful energy for all the nations is Nuclear power from Thorium LFTR, despite all the green loons anger at Nuclear. Nuclear energy is millions of times energy denser compared to solar in any form and there is enough Th for the entire planet to live well for thousands of years until fusion works. It can even help rid the world of the nuclear waste from weapons and regular nuclear plants.

You obviously don't know any chemistry because the treat of acidification is exactly zero. It is literally impossible:

- pH is logartithmic. In other words a pH of 6 is 10x as acidic as a pH of 7.

- Carbonic acid (dissolved CO2) is weak acid. A 30% increase in dissolved CO2 has negligible impact on the pH of seawater.

- pH is highly temperature sensitive. The pH of seawater changes far more in due to temperature changes than atmospheric CO2 levels.

- seawater cannot become acidified (or significantly less basic) by CO2 because it is heavily buffered by dissolved salts.

- Ocean acidification has never occurred even with CO2 concentrations 20x as high as present.
