Oceanic Carbon Uptake Varies

The Earth's oceans are thought to have taken up about one quarter of the carbon dioxide (CO2) that humans pumped into the atmosphere in the past 2 decades. While this drives acidification and has consequences for sea life, it also moderates the rate of climate change.

Researchers recently set out to create a global model of CO2 uptake using fine-scale observations on a global scale. Between 1998 and 2011, they found strong interannual variations, with the Pacific Ocean dominating the global flux variability.
