THE HOCKEY SCHTICK: New paper finds algae have to manufacture their own CO2 due to a paucity in the atmosphere
A paper published today in Nature finds that marine algae, which evolved and thrived with atmospheric CO2 levels 15 times higher than the present, required a novel adaptation to adjust to the relatively low CO2 levels during the Cenozoic era, when CO2 levels were still more than twice current levels. According to the paper, this novel adaptation was to manufacture their own CO2 at the reaction site for photosynthesis, required due to a paucity of CO2 in the atmosphere. Algae evolved more than 500 million years ago, when CO2 levels were ~15-17 times higher than the present; current CO2 levels are near the lowest levels of the past 500 million years.Visions at crossroads as carbon farm reality bites - Yahoo!7 Finance Australia
