Rapid plankton growth
Nov 28^th, 2015 at 12:26pm

'A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found.'

'"Something strange is happening here, and it's happening much more quickly than we thought it should," said Anand Gnanadesikan, associate professor in the Morton K. Blaustein Department of Earth and Planetary Sciences at Johns Hopkins and one of the study's five authors.

Gnanadesikan said the Science report certainly is good news for creatures that eat coccolithophores, but it's not clear what those are. "What is worrisome," he said, "is that our result points out how little we know about how complex ecosystems function." The result highlights the possibility of rapid ecosystem change, suggesting that prevalent models of how these systems respond to climate change may be too conservative, he said.'

It's worse than we thought. We just don't know.

It's much better than you thought. You just don't know.

Prochlorococcus.

Like our planet’s trees, Dr. Chisholm’s bacterium—a sausage-shaped creature that is little more than half a micron in diameter—obtains its life force through the marvels of photosynthesis: it absorbs carbon dioxide, and employing as its agent such sunlight as is visible in the upper region of all the seas, it regurgitates the gas as oxygen. It produces so much oxygen that in fact one in every five breaths we take is likely produced by this tiny, single-celled oceanic creature—a creature that we only learned about twenty-five years ago.

This simple fact is then augmented by another—though more properly a supposition—that is both subtler and more uncertain. Since the beast likes to live in warm water (draw a line between New Jersey and Gibraltar and another between Buenos Aires and Cape Town, and you have the approximate northern and southern boundaries of its home) it will probably increase in both its range and numbers as the world’s seas continue to warm. And since this warming is said to be the result of greater levels of man-made carbon dioxide in the world’s atmosphere, and since Prochlorococcus absorbs this gas—then the more of them there are in the ever warmer seas, so the more noxious gases will be absorbed and the more oxygen sent back into the atmosphere, until the balance is restored.

CO2 = plant food. More CO2 = more photosynthesis = more oxigen.

Clearly its not doing a very good job then given that measurements from Mauna Loa show that CO2 levels are continuing to increase

The Right Wing only believe in free speech when they agree with what is being said.

Maybe El Nino's are a function of CO2?

No. The onus is on you. You make a very extraordinary claim, despite the well established atmospheric physics that reinforce the fact that carbon dioxide is a powerful greenhouse gas, and despite the fact that there are no peer reviewed studies that support your wild claim.

The onus of providing evidence for this very strange theory of yours lies fairly and squarely with you.

JT, and I thought you were a scientist. AGW is the theory trying to overturn the null hypothesis. Therefore the proponents of AGW are the ones to provide proof. Not obfuscation.

Please continue.
