The ocean is the largest carbon sink we have, and within it sits a microscopic phytoplankton called Emiliania huxleyi. Naked to the human eye, this phytoplankton plays a critical role in drawing carbon from the atmosphere and sequestering it deep in the seas. But with climate change causing ocean water to become warmer and more acidic, researchers have found this phytoplankton could be under threat.

New Zealand’s Exclusive Economic Zone (EEZ) is a valuable asset, both economically and environmentally. Now NIWA is hoping its new digital regional climate change atlas, which maps out New Zealand’s resources within the EEZ, will highlight climate change issues and show how plants and animals in the area may respond to future changes facing New Zealand's waters.

We’re lucky to be living in a country surrounded by so much beautiful ocean. But as well as its aesthetic function, the ocean plays a critical role in CO2 absorption, sucking up as much as one-third of all human-made carbon emissions. But how exactly is climate change affecting its ability to fulfil this critical function? A new analysis by the University of Wisconsin-Madison finds some conflicting results.
