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.
