Enhanced Plankton Growth

Quote:


“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.


Increased carbon dioxide enhances plankton growth, opposite of what was expected | Watts Up With That?

Zooplankton are predatory animals and run of the mill plankton are plants. In a healthy ecosystem there must be predators and prey. If you see blue green algae growing don't swim in it but I did and it never killed me but may have built up a tolerance.

Check out how algae blooms are harmful to aquatic environments. Check out how warm waters encourage algae blooms. Check out how increased detergent use and farm fertilizers also fertilize plankton growth. Check out how as dead plankton cells compost they use up the oxygen in water thus suffocating aquatic oxygen utilizing organisms and fish.

I don't see a single thing here to celebrate other than it being proof of man's negative effect on our environment.

You're missing ex's "Heh" point.

He's celebrating "...how little we know about how complex ecosystems function." See? He told you so.

Here's the next paragraph that ex didn't post:

Quote:
Coccolithophores are often referred to as "canaries in the coal mine." Some of the key coccolithophore species can outcompete other classes of phytoplankton in warmer, more stratified and nutrient-poor waters (such as one might see in a warming ocean). Until this data proved otherwise, scientists thought that they would have more difficulties forming their calcite plates in a more acidic ocean. These results show that coccolithophores are able to use the higher concentration of carbon derived from CO2, combined with warmer temperatures, to increase their growth rate.
But wait, haven't the deniers all along been denying that human-caused CO2 has any significant effect on the climate?

Ooooooooooops...........

And if ex, or Guru Watts, bothered to study coccolithophore biology, they'd know that some species of coccolithophores thrive in environments with elevated levels of CO2 and the consequent decreased alkalinity.

Heh.....

Except the historical record has shown that this has occurred in the past, and that had zero to do with any CO2 output by mankind.

And the "settled science" crowd had used their usual scare tactics to warn that plankton would die off, even though they admit to knowing that plankton did just fine when CO2 levels were >400ppm. IOW, they've been busted, again, telling porkies. And send us more $$$$$$.


Quote:
This finding was diametrically opposed to what scientists had expected since coccolithophores make their plates out of calcium carbonate, which is becoming more difficult as the ocean becomes more acidic and pH is reduced.
And that phony "ocean becomes more acidic" meme. What is the pH today vs. 100 years ago? Slightly less base, does that make it more acidic? Does that phrase "more acidic" imply it is/was already acidic?

Interesting read:

Responsiveness of Atmospheric CO2 to Anthropogenic Emissions: A Note by Jamal Munshi :: SSRN

Quote:
Abstract:
A statistically significant correlation between annual anthropogenic CO2 emissions and the annual rate of accumulation of CO2 in the atmosphere over a 53-year sample period from 1959-2011 is likely to be spurious because it vanishes when the two series are detrended. The results do not indicate a measurable year to year effect of annual anthropogenic emissions on the annual rate of CO2 accumulation in the atmosphere.

So what if this has occurred in the past AND it had nothing to do with CO2?

That's one of the stupidest rationales deniers have ever come up with, and, you guys still use it.

Still using it shows the utter bankruptcy of your position.

This is exactly what deniers do: offer up competing theories that deny each other. This is exactly what the Kremlin does.

It's called "obfuscation." It's what deniers do 'cause they have no real case.

So unless someone agrees with the AGW/MMGW premise (collapsing as I write this), their science is no good, and the usual suspects rant "deniers".
