About one-half of Blunder is a non-technical description of our new peer reviewed and soon-to-be-published research which supports the opinion that a majority of Americans already hold: that warming in recent decades is mostly due to a natural cycle in the climate system — not to an increase in atmospheric carbon dioxide from fossil fuel burning.
Believe it or not, this potential natural explanation for recent warming has never been seriously researched by climate scientists. The main reason they have ignored this possibility is that they cannot think of what might have caused it.
You see, climate researchers are rather myopic. They think that the only way for global-average temperatures to change is for the climate system to be forced ‘externally’…by a change in the output of the sun, or by a large volcanic eruption. These are events which occur external to the normal, internal operation of the climate system.
But what they have ignored is the potential for the climate system to cause its own climate change. Climate change is simply what the system does, owing to its complex, dynamic, chaotic internal behavior.
As I travel around the country, I find that the public instinctively understands the possibility that there are natural climate cycles. Unfortunately, it is the climate “experts” who have difficulty grasping the concept. This is why I am taking my case to the public in this book. The climate research community long ago took the wrong fork in the road, and I am afraid that it might be too late for them to turn back.
NATURE’S SUNSHADE: CLOUDS
The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere and ocean to result in a 1% or 2% decrease in global cloud cover. Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming — or global cooling.

Ocean acidification is the name given to the ongoing decrease in the pH of the Earth's oceans, caused by their uptake of anthropogenic carbon dioxide from the atmosphere. Between 1751 and 1994 surface ocean pH is estimated to have decreased from approximately 8.179 to 8.104 (a change of −0.075).
Like plants, phytoplankton release oxygen into the air, and they produce half of the world’s breathable oxygen, Carpenter said.
But the world’s air is becoming so saturated with carbon dioxide that oceans have grown increasingly acidic since the Industrial Revolution, Carpenter said. Ocean acidity could rise by the end of the century because of rising carbon dioxide levels in the atmosphere, said Carpenter, who added that increasingly acidic water can burn through carbon shells that protect marine creatures.
To see whether plankton can survive and thrive in increasingly acidic water, Carpenter and two other researchers secured $1.2 million from the U.S. National Science Foundation to conduct long- and short-term experiments in the coming years.
One set of the short-term experiments will compare plankton growth in conditions that simulate today’s ocean conditions with conditions that simulate those expected by 2100, said UCSF biology professor Jonathon Stillman, who is working with Carpenter on the project at a laboratory in Tiburon.
Long-term experiments, on the other hand, will monitor clouds of rapidly multiplying phytoplankton as it evolves in acidifying water over 700 generations, according to Stillman. That will test whether plankton evolve defenses against the changing ocean conditions expected in the coming 93 years.

Absolutely freaking ridiculous...electrode based pH meters typically have an accuracy of +_ 0.02pH. So a difference of 0.05pH more acidic...they didn't have this technology back around 1800...LOL
What a joke...the difference is nothing...can't draw a direct correlation to CO2 levels even if there was.
Al Gore is saying that increasing to 350ppm and above from 250ppm will have dire consequences...OK Al...
That's a 0.0100% increase in a gas that makes up 0.032% atmosphere...wake up

Caldeira and Wickett (2003) placed the rate and magnitude of modern ocean acidification changes in the context of probable historical changes during the last 300 million years.
Since the industrial revolution began, it is estimated that surface ocean pH has dropped by slightly less than 0.1 units (on the logarithmic scale of pH; approximately a 25% increase in H+), and it is estimated that it will drop by a further 0.3 to 0.5 units by 2100 as the oceans absorb more anthropogenic CO2. These changes are predicted to continue rapidly as the oceans take up more anthropogenic CO2 from the atmosphere, the degree of change to ocean chemistry, for example ocean pH, will depend on the mitigation and emissions pathways society takes. Note that, although the ocean is acidifying, its pH is still greater than 7 (that of neutral water), so the ocean could also be described as becoming less basic.

What everyone seems to be missing is that the Ice Core data clearly shows a direct relationship between atmospheric CO2 levels and Global Temperatures. The only thing is that this relationship goes back 450000 years plus and it's clearly a natural cycle. Man-made global warming has only pushed back the time of the next Ice Age and is probably screwing up Mother Nature's way of dealing with this Natural Cycle.

Well either scientists from around the world including NOAA and Princeton Universities are all liars or you are wrong:
