Could Coccolithophores Save The Earth From Global Warming ?


Source : https://dofollownet.com

Ever heard of Coccolithophores? Despite their small size and their weird name, these tiny single-celled marine organisms are major regulators of global climate.

Most of the models used to predict climate change are based on ocean level, carbon dioxide and temperature measurements but fail to integrate marine ecosystems in their projections.

Actually, the whole process of climate and gas regulation by marine organisms is so complex that it is quite impossible to integrate in already complex models...and much more impossible to explain in details in this artile. I'll try to do my best to keep it simple, concentrating on one of the top players, the Coccolithophores.

Coccolithophores are microscopic algae that are part of the Phytoplankton and build an exo-skeleton made of calcium carbonate (CaCO3) platelets called "Coccoliths". They live at the surface of the oceans, and when they die, they sink and the calcium carbonate platelets form, over millions of years something that you are familiar to : chalk. Does that ring a (school) bell?

Calcium carbonate (CaCO3) is made of calcium...and of carbone dioxide CO2 that the Coccolithophores capture in the atmosphere. They are the most efficient "carbon traps" that Nature ever invented.

Some scientists are promoting the stimulation of phytoplankton growth as a way to counterbalance the increasing carbon dioxide
emission that contribute to the GreenHouse Effect, but it was expected that the ocean acidification will prevent coccolithophores growth, making them unable to build their carbonate armor.

Recent observations have proved just the contrary: oceans acidification seems to cause the Coccolithophores to form bigger coccoliths, trapping more carbone dioxide from the atmosphere.

This fact alone could mean that current projections about climate change are over pessimistic. But the complete mechanism of global climate regulation is far too complex to allow quick conclusions.

Excellent information Keiros.

You just forgot to mention that the Coccolithophores also play an important role in clouds formation, and that the clouds have a negative feedback on phytoplankton growth cycle.

In fact, Coccolithophores release dimethyl sulphonioproprionate (DMSP) in the atmosphere, which later can convert into dimethyl sulphide (DMS), a cloud condensation promoter. Clouds exert a strong influence on the Earth’s energy balance; changes of only a few per cent have an important effect on the climate

I just feared to right a too long and boring article, but yes, I'm aware about the cloud condensation.

I've found a lot of additional informations in this article:
Coccolithophores: Earth's Little Helpers that may interest readers who want to digg more in depth in this subject.

It mentions that approximately 3 billion tons of carbon dioxide (half the yearly production) are sequestered by and converted into coccolithophores !!! That's really impressive.

About the clouds formation and it's negative impact on Global Warming, that's even more complex. Clouds block sun rays, so coccolithophores do not get enough light for photosynthesis and die, which leads to less clouds and again to coccolithophores growth. That's a well regulated system that maintains balance over time, a natural thermostat within a growth and death cycle.

I don't know much about biology, and even less about phytoplankton but I found your article interesting enough and read it till the end.

I still don't know what you want to prove. Do you mean that the situation is not as bad as what Al Gore describes in his movie?

Please, explain because I'm lost.

Hi Laura, thanks for your

Hi Laura, thanks for your comment.

I'm not at all one of these right-wing Global Warming deniers. There are enough facts to prove that a climate change is occuring.

What I'm trying to say is that the models and climate simulations used to predict the scale of the change are not accurate enough, because they do not integrate all the parameters that regulate the global climate.

About Al Gore, I would say that is is a good preacher: but science does not need preachers, it needs data and facts.

I feel concern about Global Warning, but I think that a better understanding of ALL regulation mechanisms is mandatory in order to take the right actions.
